$17. definitely cheaper than DIY, especially starting from not knowing arduino.

So damn irritating. The old model had a simple dial. Same form factor. Now they don’t make them with a dial and you basically need to dig up an instruction manual to figure these things out.

OP, is there any advantage to the new one besides the fact that it led me to find the TS100 ?

It’s a USB header connector. They are for case-side USB ports. Here is an adapter with the right connector. https://www.amazon.com/Duttek-2-Pack-Female-Dupont-Motherboard/dp/B06Y5C7DKH/ref=mp_s_a_1_1_sspa?dchild=1&keywords=usb+header+to+usb+port&qid=1624047182&sr=8-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExNTUwWE9HU0tBSkwmZW5jcn...

Battery in the mason jar? https://www.amazon.com/Battery-Operated-Bedroom-Christmas-Decoration

Otherwise you have a wire either into the top of the mason jar (down the twine ruin aesthetic) or through a drilled hole in the back. Either of those options makes removal for travel complicated.

You just buy a boost converter. Every other method will be an order of magnitude more annoying then giving Amazon 6-10 bucks.

Adam I would try to build a small tone generator - with a led associated with each tone. Use the tactile switches as keys and a speaker for output. Be sure to use a limiting resistor on each led and the speaker so you don't fry anything;) Arduino has some great tone functions and you should have the parts. Tinkercad is a great free tool - it has a virtual breadboard with all the standard parts simulated and an Arduino emulator so you can build a circuit, write the code and test it (even has virtual instruments like a multimeter, oscilloscope and function generator). You can build some pretty sophisticated circuits with it - all free!

Wow that site is actually pretty cool, I made demonstration of what I think he is trying to do: here

I do remember a "smart" egg holder....

​

Aha:

https://www.amazon.com/Quirky-Minder-Enabled-Smart-PEGGM-WH01/dp/B00GN92KQ4

​

Used to be like $50 if I remember.

Edit:

Reading the reviews, what a train wreck. "Premium subscription is REQUIRED to use this product" -- you pay $5 per month for it....

Honestly, if this kind of thing interests you, you might consider investing in a half decent soldering iron. Once you fix one thing, you might find yourself fixing other things, until one day you are considering making your own things. Pro tip: good solder and flux are more important than a good iron. A half pound spool will last you a long long time.

As for the replacement, get a USB 3 type A cable and cut the cable at the length you need, ditto the cable on your device, then splice the wires together instead of replacing the connector directly. It will likely be easier for a first time try.

You may want to buy a starter kit. Here's one I found on amazon: https://www.amazon.com/WayinTop-Electronics-Electronic-Breadboard-Resistance/dp/B07Z1BK7NG/

Buying individual components is good when you know what you're trying to accomplish, but if you're starting out, having a bunch of common components handy and instructions for assembling them was really helpful for me.

These Arduino kits on Amazon are a pretty great value

Elegoo UNO Project Super Starter Kit with Tutorial, 5V Relay, UNO R3, Power Supply Module, Servo Motor, 9V Battery with DC, Prototype Expansion Board, ect. for Arduino https://www.amazon.com/dp/B01D8KOZF4/ref=cm_sw_r_cp_apa_CbCCyb4YGFY9H

There are hundreds of tutorials on the web for how to get started with the basics, but sparkfun and adafruit are really good places to look

Another cheaper option is IR based touchscreen. Basically a frame just above the screen with an array of IR leds and phototransistors or camera(s). Amazon for example has one for a 55" screen with 10 point touch for under $300. It could also be DIY.

https://www.amazon.com/Touch-Overlay-Screen-Frame-Interactive/dp/B074FT9T8P

https://www.amazon.com/Aluminum-Housed-Metal-Wirewound-Resistors/dp/B07LBBT943

There are many metal case resistors, 5 watt, 10 watt,etc. Google ' metal case resistors' . With a battery, it won't heat for very long.

Easiest way would be to use autohotkey (https://autohotkey.com)

create a basic script with the tutorials on their site to have a function key act as alt tab, and then just keep one note and google calendar open in seperate windows

well if its not plugged into usb or VIN, then it has over-discharge protection and cuts the OUT+ line when the battery gets to 2.9v, obviously you don't want a lipo going to 0v. its has overcharge protection when the battery is full (and usb is plugged in).

its called a TP4056, it essentially means you don't need to have a protected lipo/li-ion as its all on the tp4056 module.

but i still don't see how you expect to do this. if its plugged into usb it'll never empty the battery as it will just be topped up as its used, so it'll never cut power. its a really weird requirement you have there, what's the design?

I used template matching in this project, so it does not need any training to detect villagers. Therefore, it can run successfully during four seasons by adding templates from each season.

The price differs depending on PCB manufacturer service fees. I used PCBWay, but you can download the Gerber files here to try it with your manufacturer.

There is a free electronics class on the instructables website - https://www.instructables.com/class/Electronics-Class/ There is also an electronics simulation program in Tinkercad. It enables you to connect components together to create circuits and also connect microcontrollers and write programs for the circuits and simulate running programs etc. It's actually a lot better than my description, here's a link - https://www.tinkercad.com/circuits

Ah ok, you made it sound like you had a very specific application in your OP (your counter doesn't have a strong enough output driver).

If what you're asking is:

> Is there any way to apply a single voltage to the top of multiple strings of LEDs, and still control them individually, with no other components?

In general, no. In pure theory, maybe? If you don't count resistors, and for some level of "control". I was experimenting with falstad, trying to get it to work with some sort of resistive / diode ladder and a current source but it doesn't quite work the way you want.

Practically speaking you just get four mosfets, one for each string of LEDs, and control them individually. Analog circuits are quite a bit tougher :p

Have you tried falstad's circuit simulator? While no replacement for real calculations/functional testing, it's fun and intuitive to play around with the circuit and get you in the right ballpark with values. A 555 timer oscillator should be a pre-made circuit option in the 'circuits' menu.

http://www.falstad.com/circuit/circuitjs.html

It's look like a 5v 1.2a. I would recommend getting something like this.

https://www.amazon.com/dp/B07KXBKHJZ/ref=cm_sw_r_apan_glt_fabc_AQN6QPYR9Q5582D8QQ4P

It's a usb cable with different barrel plugs..you will also need a usb charge that can give you 15 w. 5v 3a cell phone square should work.

Edit. It's mostly a class 2 power supply. That's why it's expensive

https://www.amazon.com/dp/B087FG37Z7/ref=cm_sw_r_cp_apap_KzX3q4mR9yTs7 I bought this for that very purpose and hooked it up to a pair of 100 watt speakers, this things is amazing, I built a battery pack of 6 18650s to power it. We watched Aquaman at full volume, it was really impressive. Those old bookshelf speakers never sounded that good when being powered by amp they came with.

First of all props to you to introduce your son to electronics and ask to find a good method for him to learn it out of interest.

I remember having electronics kits which had a bunch of simple components connected by those metal spring terminals. They often came with booklets to go step by step through simple projects to gain some understanding.

Perhaps you could look at toy shops and see if they carry some educational electronics kits? I remember book shops also sold them though I'm not sure if they'd still.

I found this on Amazon, seems a bit different with magnets snapping together but looks like it goes step by step in explaining: https://www.amazon.com/Snap-Circuits-SC-300-Electronics-Discovery/dp/B0000683A4/. Looks a bit expensive but not sure if that's different in the US.

Oh boy I even found one of those kits with the spring terminals: https://www.amazon.com/gp/product/B00000IUD2

Best of luck!

There is a super-cheap stepper motor for very low-end projects: 28BYJ-48 You can buy a set of 5 from Amazon, with the motor-controller board that your Arduino or RaspberryPi can interface to, for $14.

https://www.amazon.com/ELEGOO-28BYJ-48-ULN2003-Stepper-Arduino/dp/B01CP18J4A/ref=sr_1_15?keywords=Cheap+stepper+motor&qid=1554555711&s=gateway&sr=8-15

An Arduino Nano is more than sufficient for this project, unless you want to get exotic for the trigger inputs, like voice-commands, Internet-controlled, etc.

I just bought a 10 pack for 8 bucks a couple months ago. You can get these most anywhere probably cheaper. https://www.amazon.com/gp/product/B075N69BMN

For the 500ma you're charging at what you have will be fine though. Just a passing recommendation.

Sorry to say but this isn't hard to find at all.. It pretty clearly says '16V 10uF' on it, I think a car amplifier can heat up but shouldn't reach higher than 50°C so something like this will do: https://www.amazon.com/20PCS-Nippon-Audio-Electrolytic-Capacitor/dp/B089M4DYCZ

If I understand your goal correctly, you just need a relay that is normally closed.(held open when power is applied) this would be wired into a 12V circuit that is hot-in-run, or powered when the car is on, and de-powered when the car is off. Here's an example of what I mean.

https://www.amazon.com/dp/B0748F1JK4/ref=cm_sw_r_cp_apa_i_RZnfFbM9QYJRD

If you need the jack itself too, you can buy DIY/replacements. Here's the first one I found on amazon, which coincidentally also has a pinout color coded diagram as one of the product photos.

My understanding for the transmitter the simplest implementations can be done simply with a PWM pin of a microcontroller and an appropriately sized wire for an antennae, provided the microcontroller has a fast enough oscillator.

rasppi example

I also found this googling for a much more analog approach simple fm transmitter

That's using (at least in one of the styles they're selling) SPI as it's communication signaling. Here's someone's project made to run on an SPI display: https://retropie.org.uk/forum/topic/14519/fast-refresh-rates-up-to-60fps-with-an-spi-display-ili9341

You should be able to search around for more details on how to drive SPI displays now that you're aware of what that means.

As people already pointed, welding these manually is difficult AND dangerous, there is a chance the cell explodes when you do it.

You can find special equipment to spot weld these quite easily though. But they cost quite a bit. Not worth buying for a pack, but if you want to make a business off it, spending 150$ on one would be a good idea.

here is one (not affiliated, no idea if this one is good, just an example of what you are looking for)

https://www.banggood.com/SUNKKO-737U-NEW-Spot-Welder-Machine-2_8KW-Double-Pulse-Battery-Spot-Welding-Machine-USB-Charging-Test-18650-Battery-Pack-Welder-p-1693871.html?rmmds=buy&ID=515155&cur_warehouse=CN

The derivation for this is a nice one.

Power is voltage times current: P=IV, which you can rearrange as V= P/I. Ohm's law is V=IR. Substitute and you get P/I=IR. Multiply both sides by the current (I). P = I^2 R.

The power dissipation on your cable is equal to it's resistance in ohms times the square of the current in amperes -- in this case 5.76 times the resistance of the cable (since you specified the amperage is 2.4A).

You can calculate wire resistance here: https://www.omnicalculator.com/physics/wire-resistance (or work it out by hand if you like. Or measure it.)

At my pessimistic parameters (pretty cheap thin wires), at 2.4 amperes and 5V, you'll lose about 0.12 Watts (almost 1%) of the power on a 50cm cable (which is 1m 'long' because power+ground wires). Then four times that if the cable is twice as long (a 2m cable means 4m of wire length the power has to go through).

Transferring the same amount of power (12Watts) at 12V instead of 5V means the current is only 1 Ampere. So, transmission losses would be 5.76x less when compared to 5V (0.17% power loss). The power dissipation does not go down with voltage, it goes down with current, and at higher voltages it takes less current to deliver a given amount of power.

Transmitting 2.4A at 12V means about 29W of transmitted power and the same losses as the 5V system (0.12W) -- but since you're transmitting more power, that represents only a 0.4% loss.

The nature of your power source doesn't matter -- e.g. maximum wattage (in theory). In practice it's entirely possible that some power supplies work more efficiently at some particular voltage -- however this is impossible for me to predict in any useful way.

Hope that helps! Actual amount are back-of-napkin estimate only based on copper wires with a diameter of ~1mm and a resistance of 0.02 ohms/meter

Thanks for your comment. Since I utilized template matching to detect characters, I got impressive results by adding templates for each villager from different game conditions, such as four seasons and the day/night cycle.

https://retropie.org.uk/ is an obvious one (make a cabinet)

use it as an aid to learning *nix type systems (Linux is a not Unix but closish)

do a search for "raspberry pi shields" once you find some kind of sensor(s) that interest you or spark inspiration then why not write some kind of data logger (Python is very popular on the Pi for this kind of thing)

remember that you have the potential to do much more than with an arduino and the Pi is much more than just a retropi machine

just start by familiarising yourself with the pi first, have a look at https://retropie.org.uk/ once you have everything sorted out and running all out on the desk, then you can think about how you can cram it all into a small space!

AFAIK, there is support for those so that the vibe is connected to your GF's phone, and you send the signal to that through wifi/3g so all she needs to do is stay close enough to her phone. But we are talking about a woman, and if I learned anything from fashion from my ex, it's that their clothes are not designed with highly advanced functions such as 'pockets to hold objects in'. Plenty of fake buttons, ribbons and zippers though.

Anyway, as for increasing the range of the remote control, you can't really add power to the BT or modify the vibe, so your only target is that antenna, and the first thing to take note of is polarisation.
We don't know how the antenna is located in the vibe, but if you hold them 90 degrees against each other you will have an absolutely massive signal loss. So try turning the remote on its side and see if the range increases.
Also, always point the remote right at the vibe, as the antenna has deadspots at the tip and bottom.

BT also works on the same 2.4GHz frequency as WiFi, so the high gain antennas are compatible, but with higher gain always comes larger size.
Although something like this could be small enough and a 5dB gain theoretically means it should almost triple the range.

If that is indeed the ID/CC pin, you would connect it through a 56 kOhm resister to VCC.

Here's a useful chart with the various ID pin configurations, based on use cases. Yours should be "USB-C plug to USB 2.0 Type-A plug", I believe.

Tasker and the Cars bluetooth could solve the Andoird problem. It might even be able to sense the iPhone.

if it's a workweek, at the time she would normally be driving, and there is no home wifi, and not within the home geofence, then sound an alarm. Close enough to the home and she could drive back to get it.

If you just want to base it on time, you could have it sound an alarm if she's late and it's not paired with the car.

I use Sonoff S31 wifi outlets in conjunction with Homeassistant (EspHome firmware) logging to InfluxDB and Grafana. Right now I have 3 years or history down to the minute.

You don't necessarily have to go to that extreme. You can just use the free Sonoff app to get historical, but I am not certain how long it retains it.

IR sensor will be more reliable but may not work well with dark items. Perhaps ultrasonic is the best option.

Look for replacement RC transmitter gimbaled joysticks. These types have the ability to be set up as either spring-loaded to center or maintained-position such as would be used for throttle control. Here's an example from Amazon. There are more expensive high-precision types using Hall-effect sensors also available.

The simplest method:

Get these battery powered lights that run on 3 AA batteries. Instead of using the battery pack, connect them to the RV wiring using an adjustable voltage buck converter adjusted to 4.5 volts. Connect a switch in there if desired.

Check the voltage of the battery pack to make sure it's outputting 4.5V before connecting the lights. If you don't have multimeter, buying one will be well worth the investment for this project and any future projects. You'll need it to set the voltage of the buck converter as well. Final note, when doing any vehicle wiring, make sure you're connected to a proper fuse.

FYI; I am sure you had the old style battery around but they make these that work well:

Not sure it matters but I know dewalt now has a 40v battery too.

Maybe some arm rests like this: https://www.amazon.com/Packs-Rotating-Extension-Elbow-Armrest/dp/B00QMMMFU8/ref=sr_1_2

Flux

And my favorite flux

AC is NOT DC. You connect it to the INPUT side of the power supply. You know, the one conveniently labeled "AC".

And what do you mean you can't find one? https://www.amazon.com/Reliapro-ADU120150E1012-Adapter-Transformer-Straight/dp/B00B88621O/ref=mp_s_a_1_3?dchild=1&keywords=12+ac+transformer&qid=1615227242&sr=8-3

It might, but the time will pass anyways, so might as well start now! A couple of years ago, I ordered this Elegoo Arduino starter kit from Amazon, and started doing the activities in the PDF that came with the kit. It teaches pretty simply, and I started learning. I'm still learning too. Last week I had a 'lightbulb moment' and finally understood what pull-up and pull-down resistors were for and when to use them. I've read the same stuff about them a bunch, and it just clicked for me last week. I'm in the process of using ESPHome to build a ButtonBox for my 2 year-old daughter, and I've got some other things in the works. You can do it!

Can I make a suggestion? I use these small AA battery flashlights for work every day. My go to is the Streamlight jr. LED. https://www.amazon.com/dp/B0002IO2A4/ref=cm_sw_r_cp_apa_fabc_AAHG1PNPPNS9WWQTT211

Fantastic warranty and customer service!

I've had luck on ebay and Amazon for those in the past.

While this isn't exactly the same, I wonder if it'd fit...

https://www.amazon.com/dp/B01D2I9818/ref=cm_sw_r_cp_awdb_imm_t1_F4365H3Q2K51Y1Y1S2NK?psc=1&vs=1

I have these and really like them. They fit really nicely and make good contact. At 30 A, they get a little warm but I ran them on 45 A once for about 20 minutes and it didn't hurt them.

If they should blink, then there's actually LEDs that blink by themselfes likes e.g. these: https://www.amazon.com/EDGELEC-Blinking-Diffused-Flashing-Resistors/dp/B077XCM7QZ

If you wanto to have something simulating flames, then you could get some of these led tea lights and salvage the electronics.

I am saying you should be using relays that have a 12 volt coil, so you aren’t using the regulator for the relay coil energy.

If you can’t find a 3 terminal switch mode regulator with the footprint you need that can handle the current you need, consider an off-board switch mode buck converter like this: https://www.amazon.com/Adjustable-Converter-1-25-36v-Efficiency-Regulator/dp/B079N9BFZC

That's right, not only do they never catch the dot but they never even TOUCH the dot sensation wise. It you play with them long enough like this you can see the frustration building and I've had cats start to huff in desperation. I know they love it at first but I've stopped lasers all together.

For lazy people (like me) I've found that a thing on a string on a stick is the best toy for sitting on the couch like a lump while exercising kitty. Like this: https://www.amazon.com/Feather-Retractable-Assorted-Interactive-Exerciser/dp/B07F45GGPT/

I have and I am sad to admit it has spent all of its life in a drawer owing to it's terrible user interface.

My favourite at the moment are those cheap DSO kits (you can also get them pre-made) that come with a nice case. I find I use it 95% of the time for general electronics and only resort to using my bench scope for digital bus debugging etc.

They look like this, https://www.amazon.co.uk/dp/B076HD5862

If you want one make sure you shop around as they can be obtained really cheaply.

It really illustrates how important a decent user interface is to making something usable!

I don't think you'd have interference issues with CAT-6 cables, but it may violate electrical codes.

I recommend you try one of these little guys.

Fiber is going to be a pain because you would likely still have to terminate it on each end which takes training, expensive tools and expensive connectors.

What about something like this?

Thank you! Dang, the only thing I can find is $40 for some reason

Edit: Hmm, that's actually not that expensive by the foot, they just sell so much of it at a time, I don't need 600 ft of it...

I got this electronics kit and this set of arduinos. With all this you get three arduinos and all the LEDs, capsators, resistors, diodes, transistors, potentiometers, etc... and a breadboard + jumpers and wires. You can pick a different version of the kit if you want a seven segment display or something, but this is what I got for $33

What is on the other end of the wires that you're trying to control? Seems like an odd pattern to be connecting things, especially with 3 changing polarity between the different states. I thought DPDT at first, but you've got three changes occurring here so I think you actually need 3PDT (Triple Pole Double Throw, two position) to do this

Something like this would work, but make sure what you pick is rated for teh appropriate voltage and current you're switching... https://www.amazon.com/dp/B07XHQ99HL/ref=cm_sw_em_r_mt_dp_DulzFbHGNCYBN

Sometimes it helps to build a state table when I'm thinking these things out

So you'd have the following configuration on the pins of the switch.

2 - 1 - 4

3 - N - 2

4 - P - 3

Yes, both cut power. This variant of the same model also has two off positions, but they're styled the same. I was just curious why one would be yellow and one green but I think you were right just chalking it up to /r/crappydesign

any suggestions on the type of wires I should use for this project. Is getting a really good wire over kill?

Thanks for the idea - it certainly sounds promising.

I'm waaaay over my head when it comes to electronics. If I can impose on a bit more of your time, would something like a guitar pickup wiring kit with prewired amplifier be a good starting point?

Amazon Wiring Kit

Thanks!

Hmm...that’s a little trickier than my design since the lights will be further apart. I’d maybe check out this LED strip. The lights here are individually addressable, so you can use the peel-off adhesive to stick them to the outside in the corners. You’d have to wire them together on the inside of the mask, but that shouldn’t be too hard. That strip is powered by 5V, so you could use an Arduino Nano and the 5V battery pack, no problem.

Good luck! It’s a killer mask design and I hope it all works out.

Recently, I let the little ones of my house play games on my PS4. Undoubtedly one of the controllers broke after getting too hard of a fall.

I go on amazon, ordered one of these https://www.amazon.com/gp/product/B07NYWV186/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

notes

Burning Smell I was ecstatic to fix the controller, but as soon as I do the replacement and plug in a charging cable I smelled burning. I open it back up and find the 12 pin ribbon cable melting and giving off the smell.

Power Surge on USB Port (PC) As I plugged it into my computer, my USB port starts to give my PC warning about power surge. Moreover, the replacement JDS-040 does not turn on the RGB lights when I plugged in power. Is the replacement part faulty?

Unknown JDS Board Type The charging port the controller was using previously didn't say what JDS type it was. I assumed it was a JDS-040 because of their shape. The controller worked fine, as it can't charge anymore since the port broke, I needed a replacement.

Any ideas on what I should do? Should I get another replacement JDS-040? I looked everywhere and I don't know how to solve this.

As others have mentioned, windshield/window/snowblower motors are all good options. These types of motors have a built in worm gear gearbox to convert to low speed high torque. Here is an example of one on Amazon that I think would work well for you. This one is a snowblower motor. I would suggest snow blower motors over window/windshield motors because they tend to be built more robustly.

Not sure if this is in the spirit of this subreddit, but you can do this via software if all else fails. Ip webcam for example.

Most smartphones has TRRS headphone jacks (4 conductors, Tip Ring Ring Sleeve), which means two channel output (left and right) and one channel mic level input (mono).

Since tapping into the mic connection of the phone itself likely also gives you mono sound, I would go for the much easier route of making a simple adapter from a headset cable.

Software-wise I don’t have any experience, but google gave me this, which seems capable of routing sound between most interfaces on an Android phone. I didn’t look too close, but check it out!

Edit: If the phone has stereo mics, and you feel confident enough with a soldering iron, I can’t see why not. I’m not sure if you’d need an amp to get mic level or if you can do it in software though.

Look for some control surface servos for model airplanes. They are very small and light and might fit in your forum factor.

Something like this https://www.amazon.com/Actuators-Digital-Actuator-Ultra-Micro-Aircraft/dp/B07STC2K1W/ref=mp_s_a_1_3?crid=PQT3K8T6BGRP&keywords=rc+airplane+linear+servo&qid=1671746428&sprefix=rc+airplane+linear+servo%2Caps%2C144&sr=8-3

I'm an electronics beginner so I tend to trust what's in the title, but hey, you never know. I'm interested in knowing what makes you say that it's not parallel just by looking at the images? Probably the way the batteries are arranged, with or without alternating +/- direction? But if I look at this other amazon listing:

https://www.amazon.co.uk/gp/product/B09YHMC327

I see that the batteries are also arranged in alternating direction, but it clearly says parallel again. Confusing stuff...

You are correct. I just put the batteries in the holder and measured with my multimeter. It cames out as 16.53V..... ! The battery holder specifically says "parallel" in the title! https://www.amazon.co.uk/gp/product/B08CY5LC8M. Good lesson for me to ALWAYS check with my meter.

Looking at those light strips they are designed to be powered by the USB port on a TV and not via battery so they are probably not as power efficient as they could be. Since they are controlled via an iPhone app (if I am looking at the right one) even when the lights have been switched off in the app the microcontroller will still be drawing power. You would probably get better results if you had some kind of hardware switch between the power bank and the lights.

You could also get a USB power meter to see how much power they are using in their various states and then do the math to figure out what to size up your battery capacity to for however long you want to go between charges.

Hi guys, I am currently having issues trying to find the right wire for this 12V DC Motor (https://www.amazon.de/gp/product/B087NSVDFY/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&th=1). According to the specs, the motor draws 300 mA.

In the photo you see I have tried to use 0.5 mm2 wire, however it does quite fit in the holes of the contacts, nor am I able to succesfully solder it with my iron (could be that it is not hot enough, or because the cable is copper?!).

So I am looking for the smallest guage wire, that is able to handle 12V DC at around 0.5 A of current. Would 0.33 mm2 (22 AWG) wire be fine for this application? I am fairly sure it would, just need a second opinion. Thanks!

I made a box that just makes annoying sounds. It just uses a small circuit board for greeting cards (Similar to this one) that lets you put an MP3 file on it to play whatever sound you want.

If you can make the base hollow, and just large enough to fit the sound module, then that should work.

Looks like its a 6.5kv, 30ma transformer. I have no clue how the exact replacement would be connectorized, but about any neon sign transformer rates for that would be fine. Here's an Amazon one for $33 or I think I saw some ebay links for $30ish for the same thing

Even if you hack all the case off of that unit the two connectors wil probably be stuck at that angle. Better to keep this adapter whole and get something that works:

https://www.amazon.com/Cable-Matters-Micro-Adapter-Inches/dp/B00JDRHQ58

There’s manuals out there, but can’t locate fuse data other than 10A. Measure the approximate length and diameter of the fuse clips. This will help you reference the size online. There’s only a few physical sizes of fuses, but many types. It’s hard to tell from the photo, but as was mentioned, could be a cartridge type fuse.

https://www.newark.com/superior-electric/236b/variable-transformer/dp/05F813#anchorTechnicalDOCS

At 48 volts DC, phantom current would be in the order of 5mA per microphone. For $15 this DC booster can go up to 1.5 amperes, way above and beyond any of your power consumption needs.

Technical term is a linear actuator.

But the cheaper solution would probably be to use a car door lock motor.

Unless it needs to move with a lot of force, then go with the slow but more powerful Linear Actuator.

I don't really want to switch out the electronics but rather try and make a "new" battery pack.

Would there be any way to take this and figure out a way to attach a USB-C to 3.5mm that the light would plug into?

Is it not feasible to get something like this? https://www.amazon.com/MakerHawk-Raspberry-Uninterruptible-Management-Expansion/dp/B082CVWH3R/ref=asc_df_B082CVWH3R/?tag=&linkCode=df0&hvadid=416926807659&hvpos=&hvnetw=g&hvrand=13911300747420513196&hvpone=&hvptwo=&...

or what about something like this.. I'd just need to figure out how to get USB-C to the 3.5mm jack

https://www.amazon.com/Makerfocus-Charging-Lithium-Battery-Protection/dp/B071RG4YWM?th=1

Could I solder 2 18650s in parallel, attach to a board like this, then use a microusb-to-aux connection that my light would attach to?

This is what I use: https://www.amazon.com/gp/product/B09QRS1B1B/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1

I would buy dual 4ohm coil speakers and then wire them into a 2 ohm load

Something like this. https://www.amazon.com/Cadence-Midrange-Speaker-Loudspeaker-XM644Vi/dp/B09NPKLT8T/ref=mp_s_a_1_4?adgrpid=57629734482&gclid=CjwKCAiAhKycBhAQEiwAgf19estQdBfVe0uDihKN9uW1KDdfWGMIRwniiMlLAz0BIxrZaQVM_cLtjhoCq8EQAvD_BwE&hvadid=274735633807&...

> How? I have no idea. I don't think anybody ever actually implemented the 1Gbps physical protocol.

Yeahhhhhh. Nice dreamin', folks.

The fastest I recall being implemented was the 4Mbit FIR:

https://www.amazon.com/Compex-iRE201-Infrared-Wireless-Access/dp/B00006B74G

Though evidently common palmtops couldn't take advantage of it:

http://www.palminfocenter.com/news/4504/review-compex-ire201-ir-access-point/

I assume the 4Mbps hardware would've been more common in laptops. Hmm. I wonder if any of mine in the basement have IrDA. I remember it being everywhere for a while, but I don't know if I bought anything new during that era.

I've gotten SFP's to link over a few inches of free space, I haven't been willing to drop the coin at Thorlabs to do more. ;)

The optocouplers I typically use aren't fast enough for Ethernet. There are some that use magnetic isolation instead of optical that are faster though.

The RJ45 connectors may be sending a VGA signal. If this is the case, maybe stick a powered signal repeater between the PC and the screen, then power cycle the powered repeater -- this is an easier problem to solve e.g. via a relay board or SSR.

Here is an example of a powered repeater:

https://www.amazon.com/MOERISICAL-VCYCQ100V-sr-Extender-Sender-Receiver/dp/B01GFHBJ24/

I saw this device on another post. Something like this possibly. Then get a simple USB hub between your sign and the LAN. Use a device like that below to cycle power to the hub.

Only problem might be the OFF time may be hard to get that low.
