What are /r/stratux's favorite Products & Services?

From 3.5 billion Reddit comments

Some people might have heard some rumors about a new UAT radio being tested.

Well here is it. This one only uses about 20 mA vs 190 mA for a typical SDR.

https://www.amazon.com/dp/B07JNSHCLQ/

It is a big change from a normal SDR and uses quite a bit less power and offers improved reception. This radio is based on the TI CC1310 so it is a much more narrow band receiver so it should improve UAT reception in difficult circumstances like airliners.

This chipset only operates on UAT so you will still need a 1090 mhz SDR for most traffic. There is other hardware in development at TI that would allow for a similar radio at 1090 mhz.

You will need to be running 1.5.b1 or higher for this radio to work.

Stock should be available via Amazon prime in about a week.

/u/strangerwithadvice and Jamez1970 can supply more details on how this new radio operates.

For the Canadian customers out there this will be in stock shortly and this hardware is part of the development of DIY 915 mhz ground stations to broadcast weather data.

It costs more than the small ones, but I got one of the RAM mounts from Amazon. It's easy to attach to just about any case, you can mount it anywhere and it's really secure.

Same antennas different SDR's.

Dan sells them cheaper on Amazon perhaps he just hasn't updated the site.

There is a lot of RF interference that comes from the radios and the pi. My solution was to just run an external antenna. I keep the pi on one side of the dash and the gps antenna on the other. I get ~3m on foreflight constantly.

It is a standard feature of Stratux.

You will need a serial adapter that you can change the serial number so that Stratux can tell that it should use that for serial output. The ready to go Stratux adapter is currently out of stock but you can use any CP2102 and program it.

https://www.amazon.com/Stratux-Serial-Adapter-RS-232-RS-485/dp/B01N7RNFRJ

It outputs GDL90 over serial so you will want to set the baud rate as high as possible. If you are not interested in the weather data you can either not include a 978 radio or turn it off in developer mode. The software is not clever enough to send the weather data over wifi and only traffic over serial.

Another option might be to look at Stratoflier? It is a traffic and AHRS display for Stratux that is intended to run on a cheap android phone.

https://play.google.com/store/apps/details?id=space.skyfun.stratofier&hl=en

That one unfortunately wont work.

Your GRT expects RS-232 voltage levels and that unit will only output TTL. It needs to have the right serial number/name assigned so that Stratux knows to use it for serial data. /u/strangerwithadvice can give you more details regarding that.

I have setup a GRT system using this hardware https://www.amazon.com/Stratux-Serial-Adapter-RS-232-RS-485/dp/B01N7RNFRJ/

Actually, FltPlan Go is free for both iOS and Android

When i did all I got was a multi colour page, no boot messages.

Looks like this: https://lifehacker.com/what-the-raspberry-pis-rainbow-boot-screen-and-rainbow-1768470271

The power supply is the micro usb cable plugged into an anker adapter plugged into the wall, so I don't think its a power problem.

Ordered another Pi, we'll see what happens

Here's my new Stratux build with the new case. I first built it with two SDR's and antenna, but the 1090 did not work, so I installed the PingEFB. I fly rentals, so this should work well for me.

https://photos.google.com/share/AF1QipNdfEJPnRh5QrBuY9NEFQIYSoYXcdAsnglPqU8EOUPkw5rHXYZRWeMnwXx3RpAWqg?key=MlpMWm1VQXpEdEloSUVuLTFianNrZHRGa1FJTFZB

The retailmenot item mentions it is only good in the NYC area. Looking at their main page, it looks like there is a valid $5 off coupon for all their sites.

Might have to get another!

It's probably feasible based on the fact that all the rtl-sdr front end clients like gqrx, and many others, configure the receivers on the fly with very good results, but is it practical from both a performance and development point of view?

I suspect given the right architecture (much more complex code) it could be done with reasonable results but given the fact that dongles are so inexpensive and the complexity of the code remains reasonable there isn't a lot of motivation to go the dual freq, single dongle, route.

> I think I can help, but haven't done much on golang (it looks simple enough to pick up).

For the most part, the language is straight forward and fairly easy to learn. Browsing through Go's standard library is one of the best ways to learn how to write well architected, idiomatic, Go code. And of course there's the Go lang website, which has lots of great info, and I'd recommend googling "golang gotchas."

> Can someone point me to a link that walks me through how the code is structured? Or should I just dive into it (please suggest a starting place)?

Yup, your best bet is to just deep dive in to the code.

Note, I always put the golang tools and gopath in my user folder so the pi environment variables would look like this:

GOPATH=/home/pi/gopath GOROOT_BOOTSTRAP=/home/pi/go1.4.2 PATH=$PATH:/home/pi/golang/bin:/home/pi/gopath/bin

Now untar the 1.4.2 archive to /home/pi/go1.4.2 and from /home/pi clone the go repo:

$ git clone :golang/go.git golang

Stay at tip or checkout a specific version then:

$ cd golang/src $ bash ./all.bash $ go install -v all

And you're done. The last command rebuilds all the packages in your GOPATH. Also, you can use go version 1.4+ (e.g. version 1.5) to bootstrap build version 1.5 from source. I.e. you could set, and use, GOROOT_BOOTSTRAP=/home/pi/go1.5

You may need to install some deps I've not listed to build Go from source

On a side note, there's also a Go front-end for gcc, maintained by Ian Lance Taylor one of the Go core devs, that you can install via:

$ apt-get install gccgo-go

edit: add link, Installing Go from source and info about gccgo

Highly recommend the RAM suction twist lock, but have to screw it on to the Stratux mount with 4 suction cups. Those four suction cups wouldn’t hold for me in the sun and mid-flight it was popping off the window. RAM suction was a solid upgrade:

https://www.amazon.com/dp/B001447JYG?ref=ppx_pop_mob_ap_share

I bought one of these and unscrewed the ball and the plate and just used one of the cups screwed directly into the case. You can also screw it into the bracket that comes with the crewdog case suction cup mount. That works pretty well but the screws scrape on the case if you don't replace them with counter sunk screws and holes.

​

https://smile.amazon.com/gp/product/B07VSNK6CP/ref=ppx\_yo\_dt\_b\_search\_asin\_title?ie=UTF8&psc=1

How did you get the Ram suction cup to screw into the case? (I have a similar problem) Did you start with ball mount suction cup and make a modification? https://www.amazon.com/RAM-MOUNTS-Twist-Suction-Mount/dp/B00F54LGJK/

Spoiler alert. They are actually still available on Amazon and will be for the foreseeable future. We are working on getting supply sent over to Europe in the next few weeks.

Stratux AHRS 2.0 - Sensors and Fan Controller/Raspberry Pi ICM-20948+BMP280 https://www.amazon.com/dp/B06ZZCHBHT/

I just have one of these connected to the SDR's.

https://www.amazon.com/female-right-Spliter-Combiner-pigtail/dp/B015ASUJ48/

Then an SMA-BNC cable to the antenna. Stratux is attached to a window with a suction mount and is powered by a long USB cable to a lighter adaptor.

This app supposedly will work with an OTG dongle.

http://zk4u.blogspot.com/2015/10/the-cheapest-and-most-stable-efb-ads-b.html

I tried it with every type of SDR that I have and couldn't get it to work.

>Tried it with Avare on my phone configured the same (Port 4000), not getting any data from the Stratux. Any ideas?

Download this:https://play.google.com/store/apps/details?id=com.apps4av.avarehelper

Connect to "stratux" WiFi. Select "WiFi" in the avarehelper app. Put port 4000. Select the "Listen" checkbox. Should be working after that.

Link to my log So if i'm reading the log correctly, it seems that the GPS is not passing the position to the Stratux or locking on.

There is an entire thingiverse group for Stratux bits. Just do a search there.

Or buy the injection molded version I designed from amazon. It will fit a pi4 with a few minor mods to fit the video ports.

https://www.amazon.com/Stratux-Case-Fan-White-ABS/dp/B072ND582W/

If you are based in Europe, you may try Amazon, e.g this one here in Germany: Amazon

I would be interested buying your 978 red SDR for testing purposes.

Best,

Stefan

That was really my question. If they have to be vertical, I will attach a 3 inch mast to the side of my Stratux and attach the Ping to it.

https://photos.google.com/share/AF1QipNdfEJPnRh5QrBuY9NEFQIYSoYXcdAsnglPqU8EOUPkw5rHXYZRWeMnwXx3RpAWqg?key=MlpMWm1VQXpEdEloSUVuLTFianNrZHRGa1FJTFZB

Hello,

My setup is very similar to yours but I'm struggling with the partial old/new setup instructions, which have little in common. I'm new to Stratux and appreciate the work and contributions of the community. I've used Stratux in it's basic form along with Avare and now I cannot fly my experimental AutoGyro MTO without it!

I'm running the latest Stratux Europe Edition 1.6r1-eu027 (With US settings) and I purchased the USB WiFi dongle to access the Internet via my phone's hotspot. So far I haven't been able to get my R-Pi 3B to recongnize the WiFi dongle.

Could someone please share the steps necessary to get the R-Pi to recognize the add-on WiFi device

Thank you!

I was not successful with my attempt. I did however find a tool called webmin and I like it.

Take a look here: http://www.webmin.com/index.html

install I followed here: http://www.webmin.com/deb.html

It is a complete web based administration tool. With SSH,file manager,and plenty of other tools!

Hi Lisa,

The way to install the full image is to write the image to the SD card using a program from your computer. If you're uncomfortable with that, you might want to wait for the update .sh file to be released when .9 goes stable. If you're on Windows, I use w32diskimager which is pretty straight forward.

Hope any of that helps!

The Go compiler is always cross compiling and defaults to what it identifies the host system as, therefore, provided GOOS, GOARCH, and GOARM aren't being set they will/should default to GOOS=linux, GOARCH=arm, and GOARM=7, but it could be that the GOARM variable isn't configured (ie defaults to 6 instead of 7) since it's kind of unique and specific to arm. "go env" should show the settings.

From the go install via source page

$GOARM (for arm only; default is auto-detected if building on the target processor, 6 if not)

edit: if GOARM isn't being set dynamically at compilation it can be pre-pended on the compilation line in the make file.

Note, Armv6 does have VFPv2 optionally but it is usually implemented, Armv7 does have VFPv3 optionally but it is usually implemented

I’ve used both. The external is really great if you fly commercially and just want to use for reference and also nice if you want to keep the stratux down on the floor or in a pouch while flying yourself. Additionally, if you get the external it will still work without the external antenna.

On a side note - I replaced the antennas with shorter less conspicuous ones and prefer that. They have kits on Amazon. Stratux ADS-B 3dBi Gain Small... https://www.amazon.com/dp/B07Z8FT94M?ref=ppx_pop_mob_ap_share

I would highly suggest doing this pieced together with the kit list on the stratux website and getting a gigantic external battery. It’s half the price and was a fun little project. The battery I have is 30000mAh and lasts a full 9 hour flight to Denmark and some even have solar panels built in.

Happy to help. I use a torch to clean up stringyness but i have also messed with my profiles over years to minimize it. I suppose you could also use a lighter. The torch is just so fast when your prototyping all day.

(https://www.amazon.com/gp/product/B01LXNYTFT/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1) is what I am using. The 6 ft one might work OK too.

Check with the manufacturer manual or email them.

Im not familiar with your unit since I built mine

Buttt pretty much every issue with the stratux can be fixed if you re flash the card or buy a new power cable (anker is the most popular) i recommended using a 90 degree adapter and velcroing it to the stratux. This relieves the pressure on the raspberry pi and doesn't wear out the power cables nearly as fast

https://www.amazon.com/dp/B06Y4FDVNN/ref=cm_sw_r_cp_apa_glt_fabc_MXZ9QP9VRDTW6QZTVNRS?_encoding=UTF8&psc=1

I assume you have an antenna marked 1090 and another marked 978. Try swapping them and see if the behavior of the unit changes. You might see the towers more consistently. If so, replace the antenna marked 978. I have a small 978 antenna which is bad, but a larger replacement (5dBi) that works well. https://www.amazon.com/NooElec-ADS-B-Discovery-Antenna-Bundle/dp/B01J9DH9U2

I am running the original clear case from years ago. https://www.amazon.com/Stratux-Case-Fan-Clear-Acrylic/dp/B01ERQPPWU

I've been using BadElfPro on Bluetooth to get gps data to ForeFlight.

Will the new internal GPS USB for STRATUX fit in the older case?

I have the original nano SDRs stacked. I see from the updates that they need to be side by side on the lower USB slots for the GPS to be above the 978 SDR.

Will everything fit the old clear case or should I consider the new white case?

I have not needed the STRATUX lately, the Arrow III I am currently flying has the Apparo STRATUS transponder with ADS-B wifi to the iPad for all ADSB data.

It looks a lot like the original Stratux case. /u/strangerwithadvice made a ton of those early on.

https://www.amazon.com/Stratux-Case-Fan-Clear-Acrylic/dp/B01ERQPPWU

I actually did a lot of the things you have done such as integrating a battery but in the end it just makes it a bit harder for people to make so we ditched the idea.

You should publish it on the Stratux thingiverse group. Lots of different case options have made over the years.

https://www.thingiverse.com/groups/stratux/things

Update: I essentially got this working using the new instructions, though I didn't completely undo everything from the old settings. The key was getting an adapter that actually had RPi drivers. I got one off Amazon using the Ralink 5370 chipset.

This is what I use:

https://smile.amazon.com/gp/product/B07W5F556K/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Along with:

https://smile.amazon.com/gp/product/B07K4HTBSM/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1

It fits very nicely on the standard case, if you cut off the retaining portion of the bracket. It's also very thin. I then just use the velcro strap to hold it all together.

there are a few choices https://www.amazon.com/Rigid-Carry-Stratux-Tablet-General/dp/B07V1K2ZKK/ref=sr_1_5?dchild=1&keywords=case+for+stratux&qid=1605542456&sr=8-5

I do have the AHRS 2.0 installed, I am not entirely sure if that part is the one you refer to. I know my ahrs works fairly well, but I am not certain how to test against the baro pressure. I believe once I took off ownship, the altitudes starting to display correctly again on foreflight.

hi, I have same issue but solution does not work.

I got everything new as of yesterday from stratux amazon store.

I run 1.5b2 , pi3b board

Antennas and SDRs ( https://www.amazon.com/gp/product/B07K1GZMM9/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 )

UAT/Gps runs fine. I can get traffic and see towers in UAT

Web gui shows 2 SDRs connected.

I cannot get any 1090 messages, even under airliners, next to the airport.

I run the SDR serials script (only for v2, no failsafe) no luck

I tried without UAT installed, no luck

Switched Pi3b boards, no luck

​

Shall I return it or is there anything else to troubleshoot?

Thanks!!!

Hello everybody and thank you a lot for your answers ! :)

The aircraft of my students is equiped with a L3 Lynx NGT-9000 and I found this in the manual :

"Traffic Advisory System (TAS) The Traffic Advisory System (TAS) is an optional feature of the Lynx NGT-9000. This feature provides the capability to interrogate nearby aircraft transponders and issue Traffic Advisory (TA) alert as well as a voice audio output that announces Traffic Advisories and relative altitude to the flight crew. This option requires the installation of a directional antenna."

This is what I want to do, it will not be possible with the Stratux ? :(

I have bought his kit of antennas : amazon antennas

I have bought this kit of adapters but they are too big : SMA right angle

I would like the adapters thats fit on the stratux antennas.

Anyways, if there is no way to see the nearby trafic with the Stratux, I will just not use it and ship the parts back.

A Stratux user told me that it will work in the Montréal aera thank to the Burlington ADSB tower.

Do you think it can't do what I want at all ?

Thank you a lot for your precious advices !

No direct link Scroll down to have a question ? On product page and type in ‘kitchen foil’

It is just an antenna. If you look on the backside of the GPYes there's a beige square thing. That's the antenna. The external kit just moves that antenna outside the case so you can remotely mount it to have a better view of the satellites. The VK-162 (https://smile.amazon.com/dp/B01EROIUEW/) is a different story. It basically is a GPYes with a long USB cable on it and is more what you're thinking. That moves the entire GPS module (antenna and everything) outside the Stratux. You can do the same thing by taking your GPYes and putting it on a GPS A to A extension cable, but it doesn't have a nice housing around it like a VK-162. 2 different ways to do pretty much the same thing. Get the antenna away from the noisy electronics in the Stratux case and give it a better view of the sky.

Thanks for the response and clarification, even on such a basic question. I think I may have characterized the external GPS wrong as it's not an antenna per-se but a gps puck (the amazon listing is here). I was under the impression they are separate GPS units.

I just spent an hour or so outside with the stratux for calibration and locking satellites and what you said now makes sense. It appears the internal GPS had ~3-4m accuracy and then the external drops that down to 1.5-2m or so. So having the option to move the GPS location out of the unit definitely seems beneficial to getting better accuracy, I think I will utilize if I have a trip where the accuracy is needed.

Clear skies!

The official mount is decent, but the suction cups included with mine (in 2017) were junk. I bought a RAM mount suction cup - https://smile.amazon.com/dp/B008JGZMZK/ - removed the ball via the screws, and drilled + countersunk holes through the Stratux holder to attach it to the RAM mount.

I was contemplating the same but ordered a 90 degree whip to take some of the stress off the connection. Solved my issues... RIIPOO Micro USB Extension Cable Right Angle

I added an external antenna. I consistently see 3m or less. It's the radios causing the interference so get the gps antenna as far as possible from the pi and the sdrs.

Since you know you're on unsupported hardware, you might try looking at dmesg and some of the logs in /var/log. Obviously, you'll need a way to get into the system after it's locked up but before you reboot it, so a keyboard/monitor might be easiest.

That said, if your power output's only 4.64 volts, that's probably your problem. Get a better power supply and USB cable - bigger gauge, the better. These have 20 ga power lines: https://www.amazon.com/dp/B012VZ7MUM/

I am an aircraft electrician/ avionics guy and what we use to reinforce connectors is called RTV. It is a silicone-based product and won't conduct electricity. You can slather it all over your board and be fine. I used it to secure everything in place on my stratux build because my GPS kept coming unplugged.
https://smile.amazon.com/J-B-Weld-31310-All-Purpose-Silicone/dp/B00M2USVI4/ref=sr_1_3?crid=1XW9SLI8JULZZ&dchild=1&keywords=dielectric%2Badhesive&qid=1597056033&sprefix=dielectric%2Bad%2Caps%2C215&sr=8-3&th=1

Also, you can try resoldering the micro-usb connector back on but it is probably the tabs on the inside that aren't locking in the cable in tight enough anymore. So you would need to replace the whole connector by soldering. If you don't know your way around a Soldering iron then your best bet is probably to replace the whole Pi.

You're probably gonna have to get a new pi or fix the connector. But your primary issue is likely the plug coming out too far giving it leverage to put stress on the connector.

Try this

https://www.amazon.com/StarTech-com-91cm-Micro-USB-Cable/dp/B003YKX6WC?ref_=fsclp_pl_dp_1&th=1&psc=1

Then Velcro the cable down to your case so it can't move around so much.

There are 2 different versions of the GPYes module sold with Stratux. The older one had to be put on a USB extension cable. THe newer, current one has a little u.FL port so you can put an external antenna on it. So the module itself stays inside the Stratux and just uses an external antenna. This is the antenna puck on Amazon.

Yeah I have pictures but they’re not hosted anywhere so I can’t post a link to it. I’ll try a link to it on amazon. But the one I got is mirrored from what it shows. I ordered another one and it should be here tomorrow.

It might be easier to just buy a preloaded card

Stratux Software Card (pre-Programmed Micro SD Card) - v1.5b1 https://www.amazon.com/dp/B01I0G15YU/ref=cm_sw_r_cp_api_i_5QdBEbM145TJ6

Here is one from stratux off of Amazon. Other than that just buy an SD card reader.

I found DIYmall VK-162 GPS Module 7 Gmouse USB Interface Navigation for Stratux Support Google Earth on Amazon, which looks to be just the USB module for the external USB antenna from the official parts list.

The internal GPS's work OK at best.

One thing to watch for is to be sure there are antenna wires running over the top of the gps chip as that is where the antenna is located.

I found that by using the external GPS chip as found on Amazon:

https://www.amazon.com/VANWEI-VK-162-Notebook-Navigation-Support/dp/B01N01W8SK/ref=sr_1_9?dchild=1&keywords=stratux+GPS+chip&qid=1574510609&sr=8-9

You will get <3m accuracy most of the time

It sounds like you have covered everything except the card reader hardware. Have you been able to flash images other than Stratux? I use this one and it works fine with Etcher: https://www.amazon.com/Anker-Portable-Reader-RS-MMC-Micro/dp/B006T9B6R2/ref=sr_1_5?keywords=card+reader&amp;qid=1571774145&amp;sr=8-5

As suggested earlier, sounds like you are missing the radios and antennas. Link below ...

https://www.amazon.com/Stratux-1090ES-UAT-Radios-Antennas/dp/B01M7NMWCD?ref_=ast_sto_dp

> I'm only getting a fix on two GPS satellites on the ground. Could the duct tape be causing interference?

According to wikipedia, "powdered aluminum pigment gives traditional duct tape its silvery grey colour".

So, it seems plausible to me that the duct tape is screwing up your GPS reception.

With the GPYes v2, you can get an external antenna that would probably solve your problem by not making the GPS signals try to get through powdered aluminum.

Also, I have no idea who runs stratux.co, but you should check out the parts list on the official Stratux website, http://stratux.me, for newer, better radios for your next build.

Instead of getting a vK-162 why not get an external antenna? It is the same shape as the VK and fits in the mount I designed that you are getting printed.

https://www.amazon.com/Stratux-GPYes-2-0-External-Antenna/dp/B07NDPXDDY/

I cut 2 of these up, one under the Anker Batter Pack for the dash, and one on top of the Anker to secure the Stratus.

https://www.amazon.com/gp/product/B00V5099GU/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&amp;psc=1

Nice sticky stuff, but doesn't mar up the dash of the Schools 172P.

Here's a link to a set of antenna connectors

2PCS RF coaxial coax cable assembly SMA female to MCX male right angle 6''

https://www.amazon.com/DHT-Electronics-coaxial-assembly-female/dp/B00CP17WMG/

u/helno : any thoughts on how one might use the new UAT with an external antenna? I've used the dual MCX to single SMA splitter (https://www.amazon.com/gp/product/B015ASUJ48/) as suggested in a previous post. With the u.FL-to-SMA pigtail, have you come across a splitter with the different connectors?

The Nooelec antennas include two sets for the same price because they are kind of crappy.

https://www.reddit.com/r/stratux/comments/7qlsj8/nooelec_vs_stratux_antennas/

Get this set with the V3 UAT radio it performs better and uses less power. https://www.amazon.com/Stratux-1090ES-UAT-Radios-Antennas/dp/B07K1GZMM9/

1) 6 ah will last roughly 4.5 hours per charge. If you are using the latest V3 UAT radio it will last longer.

2) the image is compressed. It is 2 gb when fully expanded and leaves around 300 mb free space. Stratux does not really log anything.

3) Moving the GPS away from the rest of the electronics will always improve accuracy but at the expense of portability. Most people will not notice the difference between 3m and 1m GPS accuracy.

Keep in mind that if you have two USB radios AND a USB connected GPS, you will need 2.4A of power. If you underpower the Stratux, it will not function correctly.

EDIT: I use this one, and it works just fine for me: https://www.amazon.com/gp/product/B00VH84L5E

Well, now... this is where I deviated from the build instructions. I went with the "more is better" line of thinking and got the Anker PowerCore 10000 battery. It comes with a relatively short (maybe 12") power cable that I have been using.

Edited for formatting.

The wiki article and the original document point to the Stratux store on Amazon. I originally followed that link to purchase the dongle. As of this time, it is listed as "Currently Unavailable." This is why I purchased the unit I did, not knowing it would need to be updated before it would work with the Stratux.

Thank you for the comment.

Maybe I didn't use the correct wording. When I said "bench tune them" I was under the impression they are able to "pre-program" the hardware to optimize the receive sensitivity in the specify application frequency band (if they could do that it would be news to me) before they ship them out.

Read this from their listing on Amazon and you can see what led me to ask the question.

If you are looking for an assembled and tested unit I do have one in stock. https://www.amazon.ca/RXWX-Dual-Band-ADS-B-Receiver/dp/B0741DMK8P

I cannot actually update the listing to show the firmware version number since that is a shared listing. You can see that the US listing still shows 1.4r2

I always ship with the latest firmware version so it is likely that unit has the latest firmware or one back. 1.4r5 is only relevant to Foreflight users and updating the firmware if you require it is pretty straightforward.

As far as hardware differences go the main vendors all use a common hardware platform, My white ABS case, Dan Murray's antennas, Chris Young's low power SDR's GPYes and AHRS module. You will see this same package sold under different brand names such as the FlyQ Merlin, ifly as the RXWX, and then the units sold by Crew Dog electronics and Everlast concepts.

Where things begin to differ is that some are sold with batteries and carrying cases, suction mounts etc. I prefer to sell kits, I sell 10 kits for every preassembled unit stocked.

There are quite a few people out in BC flying with these. They are very popular in areas close to the border so BC southern Ontario and Montreal buy a lot of them.

I bought the standard case, but added the ram suction cup. I’ve used the ram products in the airline cockpit and they are tremendous. I’m glad I went with one of these as opposed to four “normal” suction cups. This is just my personal PSA. https://www.amazon.com/Mount-with-Suction-Cup-Base/dp/B001447JYG

Apologies! It was in the video comments. Here's an Amazon link.

Hi I am considering making a stratux, and want to implement FLARM, just to be sure, this https://www.amazon.co.uk/gp/product/B076GWVNHS/ref=ox_sc_act_title_3?smid=A1TIGMJ4AZ1K1A&amp;psc=1 would cover everything I need? or is a separate receiver required for FLARM (868 MHz)?

Stratux "AHRS" is a software implementation based on combining GPS data (of certain supported GPS sources, not all) and "gyro" data from add-on optional chipsets installed to your build.

What MPU unit are using for your gyro data? Often the MPU has a companion BMP unit that supplies the baro data. I expect that STRATUX will not know about the BARO data on your Ipad. Whatever EFb app you use on the Ipad might be able to access the Ipad baro.

The unit below is a common way of getting MPU (for ahrs) and BMP (for baro). It also has the fan controller included: https://www.amazon.com/gp/product/B06ZZCHBHT/ref=oh_aui_detailpage_o08_s00?ie=UTF8&amp;psc=1

I just got one from Amazon. They appear to be back in stock. Stratux AHRS Sensors and Fan Controller / Raspberry Pi MPU9250+BMP280 https://www.amazon.com/dp/B06ZZCHBHT/ref=cm_sw_r_cp_apip_7RpFzoyjBNMPq

Which "new white ABS case"? I'm in the process of some updates and am trying to select a case. I'm tempted to go with the "recommended" case, https://www.amazon.com/gp/product/B072ND582W/ref=ox_sc_act_title_1?smid=A1FY2FJYL6LK7D&amp;psc=1 but, reading the specs, it says it's 5.5" X 2.5" X 3". The photo looks like only 1.5" like most of the cases I've seen. Is the 3" measurement correct? Seems unnecessarily bulky.

Here is what I use. Splitter connects directly to the SDR's and then a single cable straight to the antenna.

There is serial GDL90 format data available. If you have one of the programmed serial adapters later versions will automatically send data.

Anker is my go-to place for anything mobile power related. They have a dual 2.4A for $9.99.

It doesnt have a voltage indicator, but my plane has one of those with temp and density/pressure altitude readout.

I was wondering if somebody was going to pick up on the headset config. I tried to crop the picture in such a way that it was not real apparent. :-)

I have been on a headset quest for awhile now, experimenting, etc. I put Headsets-INC ANR modules in my older Softcom headsets and built my own version of a Clarity Aloft before buying a real one (which I don't like because of small ear canals).

I had a pair of QC-25's for my non-flying life and found this boom microphone cable. It seemed very interesting so I bought one:

https://www.amazon.com/Headset-Buddy-ClearMic-Cancelling-Microphone/dp/B0195SUXMM

..to see if I could make it work. I built a small box with a set of matching transformers and volume pot in it and the ANR headset part of of the QC25 works great. I even tried to hook the microphone up through the box as well. If I had even a small amount of EE and audio engineering experience, I'm sure I could make the mic work. I ran out of time before departing for KOSH though.

In the picture, I'm actually wearing my Clarity Aloft under the QC25's for the microphone part only. That setup worked very well.... right up until departing KOSH and my QC25 ANR battery died. At that point, I was nearly completely deaf to ATC which made for an interesting 30 seconds while I changed the battery.

With the revelation that I couldn't hear nearly at all with a dead battery, I now consider the QC25 not a good choice for an aviation.

My Bose A20's arrived yesterday! Bose is very proud of them and it hurt a little but they make a beautiful headset.

does this unit (https://www.amazon.com/Stratux-Sensors-Controller-Raspberry-MPU9250/dp/B06ZZCHBHT/ref=sr_1_3?ie=UTF8&amp;qid=1496870371&amp;sr=8-3&amp;keywords=stratux) use gps for ahrs or is it a true ahrs sensor?

Awesome. That's all I want! I assume when https://www.amazon.com/Stratux-Sensors-Controller-Raspberry-MPU9250/dp/B06ZZCHBHT/ref=sr_1_35?ie=UTF8&amp;qid=1493845954&amp;sr=8-35&amp;keywords=stratux is available I will be able to run the beta software with it.

For someone new to this whole thing, I assume the installation of the AHRS sensor will be easy enough? Do I require an external GPS to use the AHRS hardware? I have an iPad with LTE, so it has the internal GPS.

Thanks again for answering my questions. All I have to give in return are upvotes, but I will definitely be a new Stratux customer imminently!

I've had great lucking using the ram mount that screws into the back of the summitlink case.

I used these: Amazon SDR Kit and I'm running the current version of stable 1.2r2

I've been tinkering with designs and now offer a fully assembled Stratux unit complete with DMURRAY14 antennas, low power SDRs, and battery pack. Decided on the white SummitLink case to block light for night flying and allow for the ram mount option. I've found having vertical orientation makes a big difference at high altitude (FL200 and higher). Appreciate any feedback! Products assembled and tested by a couple of military pilots.

Here is the connections needed for an MPU9250.

If you want a drop in solutin you might wanto to just buy one of these.

https://www.amazon.com/dp/B06ZZCHBHT/ref=cm_sw_r_cp_ep_dp_855ezb9PA606E

Appreciate it! I attached four rubber bumpers to the bottom to keep it from sliding for people resting it on the glare shield like you mentioned. Also keeps the case from contacting and potentially scratching the windscreen.

It is a tiny USB OTG adapter. Don't use it with a pizero as the EMI reduces the ping's range to almost nothing.

Works great in a pi3 setup.

The only omnicharge I could find was almost $300. Is that the model you're referring to?

That's exactly what I wanted. Unfortunately, doesn't ship to Canada... :( I did find someone who will ship a 5-pack, but that seems like such a waste...

[update] Found one... $3.85 and free shipping! https://www.amazon.ca/dp/B01N52EPSK/ref=pe_386430_126088100_TE_item

Just to update: I saw this post https://www.reddit.com/r/stratux/comments/620hjx/using_the_zero4u_usb_hub_with_the_raspberry_pi/ I see there's interference issues from the p0w but should that be negated if I'm using a "regular" USB hub connected via OTG. I was using this one: https://www.amazon.ca/ORICO-SuperSpeed-10-Port-Premium-Detachable/dp/B00CBEVTIA/ref=sr_1_4?ie=UTF8&amp;qid=1490723001&amp;sr=8-4&amp;keywords=orico+usb+3.0+hub

Turns out my OTG cable is broken (tested with some other android devices) so I'll need a new one of those anyway.

But is working? I mean are you able to have both on and see any 1090 traffic?

btw, are this the radios that failed? https://www.amazon.com/gp/product/B01M7NMWCD/ref=oh_aui_detailpage_o01_s00?ie=UTF8&amp;psc=1

I'm asking because I just bought a set

Is this what you're referring to?

There are multiple options on Amazon, search CP2102 RS232. Not a lot of prebuilt cables though, you may have to solder or crimp it yourself, it's just 2 wires so an easy job. I built stratux into a case for mounting behind the panel, and brought the power, screen, and serial out connections to a DB15 connector on the side, so I just used a small converter similar in form factor to the SDRs:

USB TTL 232 485 converter serial module https://www.amazon.com/dp/B01CNW061U

Be sure as you're picking modules that the output levels are correct for the device you're connnecting -- some of the modules only convert to TTL which may not work with your device's serial port.

I used my old IOGear GBU321 to set this up. Auto reboot and my stratux pairs to my skypro and rebroadcasts the GPS Signal over wifi. My ipad can still pair to it via bluetooth.

I wanted to report that I have successfully connected my Stratux to my GRT EFIS. I used the CP2102 based USB adapter (https://www.amazon.com/gp/product/B014PBYER4/ref=oh_aui_detailpage_o02_s00?ie=UTF8&amp;psc=1) on the stratux (TTL level output) and changed the product name as outlined above. I used an FTDI- based USB adapter on the GRT (https://www.amazon.com/gp/product/B014PBYER4/ref=oh_aui_detailpage_o02_s00?ie=UTF8&amp;psc=1). My research shows that the GRT is best able to use the FTDI drivers. This converts the TTL back to USB. I have not tried using serial into the HXr, as all 8 are consumed with other interfaces. I am pretty sure that products that I used won't work for connecting to a serial port, as they are TTL level interfaces.

I have confirmed that I am getting weather data and I think I am getting traffic data. My GRT also gets TIS traffic from my transponder and I haven't yet turned it off to be sure that I am getting reliable taffic data from the Stratux.

I used these : https://www.amazon.com/gp/product/B01F76BPAU/ref=ox_sc_act_title_1?ie=UTF8&amp;psc=1&amp;smid=A3T95V05QKJ0CN

For my case holder I made for Helno's squared off case http://www.thingiverse.com/thing:1741150

They hold well, but are a little big.

Big yes on this. I think this case could be adapted for yolk mount. https://www.amazon.com/Premium-Touchscreen-Official-Raspberry-Display/dp/B01GQFUWIC/ref=sr_1_50?s=electronics&amp;ie=UTF8&amp;qid=1474313338&amp;sr=1-50&amp;keywords=raspberry+pi+3+case

Here's a good link to determine speed of SD card. https://www.sdcard.org/developers/overview/speed_class/ I think the following SD cards would be good: https://www.amazon.com/SanDisk-MicroSDHC-Memory-Adapter-SDSDQUAN-008GB-G4A/dp/B01CCEDLNE/ref=sr_1_5?ie=UTF8&amp;qid=1470243295&amp;sr=8-5&amp;keywords=micro+sd+card+8gb+pack+speed+ultra

Playing around with this more, I got the Stratux to operate using the GPIO serial port and a USB to TTL-UART cable (https://www.amazon.com/gp/product/B008AGDTA4)

I had to use a power USB hub though, and the TTL-UART cable powers the Stratux from that.
