Made this a while back. The minecraft server is a regular one without any mods and a webserver that can run cgi-scripts.
How it works: The lever not only controlls the lamp but also sends a signal to command blocks that writes to the server log if the lamp is powered or not. The logfile is read by a script that then sends a message (via the serial port) to an arduino with one of these. The arduino then sends a signal to the desk lamp, connected to one of these.
To make the phone controll the redstone lamp, it simply make the script running on the webserver send setblock-commands to change the lever.
P.S. I'm not only bad at titles, I also suck at explaining things.

Get a lock for her door.... Please.
Plus, maybe a small camera that records motion. ( http://www.dx.com/p/hd-720p-12mp-mini-camera-photograph-video-voice-record-motion-detection-webcam-131040 ) set it up... and see....
you should probably buy a high-powered wifi adapter, an aimable yagi wifi antenna, and some free aiming software and get your neighbor's wifi all the way from your own room.
Note: I used to be a notorious wifi leech until all the neighborhood signals dried up.
Physics are against them. There's only so much you can do with the teensy little drivers in modern devices. They're never going to sound good; the best you can hope for is that they sound slightly less bad than the competition.
If you need more volume or better audio quality, a good bluetooth speaker can be had for as little as $20 or less. With that being the case, it's a tough argument to make that manufacturers should devote precious real estate to upgrading the speakers on their devices, especially when even the mere hint of bezel is enough to send r/android into a frenzy.
Just fyi, on mobile (edit: or desktop) you can hyperlink text by using this format: [Text to be displayed](link URL)

Sorry for the long link. I'm on mobile :/
Those are called ads man, or ads pretending to be content (see relevant south park season).
Anyway they are like the old X2000 lights of like 2008 that came in 3xAAA, 1x18650 and what not.
Was kind of popular in the cheap light community back then, and I have the 1x18650 verson when I first started getting into flashlights. It should not cost more than like $7 if not less than that.
Example link from dealextreme.
I mean it still lights stuff up, but it's not at all the worlds most powerful anything, and zooming to some people is the bees knees, but with the lens the beam is not great if you care about that.
It's using old tech, and gets hot as well, but to people who don't know any better, or care then it's fine. Just don't be ripped off/fooled into thinking it was ever sold for $200. It was like $12 8 years ago.
I use this one, it's all right, but it's a bit top-heavy when there's a smartphone on it (in my case, a Nexus 5X).
Un frontal mortel impliquant que des cyclistes, c'est particulier...
C'est juste une hypothèse, mais peut-être que les cyclistes n'avaient pas de lumières. Rouler sans lumière est dangereux, surtout que l'investissement est négligeable. Personnellement, je recommande ce modèle, à 5$ pour la lumière avant et arrirère : http://www.dx.com/p/2-led-3-mode-white-red-light-fog-bicycle-lights-black-pair-2-cr2032-51737#.VdseBvl_NBc (J'ai aussi entendu dire qu'on pouvait les trouver en magasin).
If you just want the whole block lit up, then yeah, you could wire it up directly and have it flash the proper colours. If you want to control patterns and such, then you'd need a controller for the matrix - its easier to hook up (less wiring), but more coding involved.
Here's an example: Controller. This essentially lets you control the whole matrix, colours and patterns, over 3 wires to your teensy. More coding involved, but you eliminate all the soldering and wiring OP had to do.
To further simplify hookup, there is an arduino called the Rainbowduino - its a controller, with an arduino built in. You simply plug the panel into it and program the on-board chip - no teensy required.
I got it a bit cheaper here: http://www.dx.com/p/neje-diy-low-temperature-stirling-engine-antique-brass-black-365003

I can really recommend it, it's great fun to watch!
No, a hijab would be totally inapropriate. But a bikini, a boxer a g-string or basically any other piece of clothing is appropriate though. Heck even toilet paper is alright.
Third party mount. http://www.dx.com/p/wearable-head-belt-mount-strap-for-gropro-suptig-black-24cm-185124#.VXTPhXA8KrU

Once I realized it was a crayon I got it together. :) I guess they're just known as Haws Crayon? Not seeing the same one as yours though. They all seem to be the smiley face version.

In the past I've made several orders of 20-50 pairs of each of the red and white lights in these links
and tested them and put them pairs of one red and one white. I'm not specifically committed to them and it's entirely possible that I can do better somewhere else now but this is what has worked well in the past for me personally. My specific requirement was under $5 per pair and could be clipped onto a bike without tools. I'd prefer they not use coin cell batteries but that is the tradeoff I'm making to get the other two things.
These lights can be found in lots of places for lots of prices. And just dx.com and affiliates has half a dozen pricing schemes you can use to buy these. Depending on where you are and how many you're buying different schemes will work better for you.
Sorry, I guess if you didn't know about the cables I guess it was pretty ambiguous.

Não só o Suiço, o padrão Europlug é a coisa MAIS COMUM na europa continental, a maioria dos plugs por lá vem com europlug, que encaixa perfeito aqui.
Alias, tudo o que compramos da China vem na opção Europlug (Ou plug UE), que encaixa perfeito nas nossas tomadas.
As opções dos vendedores são o plug escroto americano (com pinos chatos, que eram o único tipo possível de ser feito em 1900, martelando pedaço de aço, eram tempos de manufatura), algum pino quadrado alemão ou britânico, e o europlug.

Browsing http://www.dx.com/ for cheap Chinese crap can be entertaining. $10 spare is good for picking up just-in-case supplies like bridges, connectors, memory card adapters, etc. Grab a cheap bluetooth adapter and play Wii games on your PC with Dolphin.
Haven't tried tinydeal, but I have good experience with dx.com, their alternative is almost as cheap at $3.97
(not advertising for dx or anything, just as an alternative store)
I don't honk/yell/rev or do anything to cyclists while I'm in my car.
But I do try to keep some spare cheap rear lights in my car to hand out to ninja-riders, if I see them out at dusk/night. I have given out a handful of these, but I just made a new order of these which are cheaper so I can hand more out.
That's a TRRS connector. Probably power/gnd and signal - either two out or one in one out.
It looks a little bit like a nurse call button but I don't think they need that many signal paths.

I REALLY recommend getting one or two aluminium alloy tripod adapters The plastic ones break. (available in multiple colors) You can also get alloy mounting thumbscrews too that are easier to use. I recommend that too.
http://www.dx.com/p/petc-s10-5t-usb-output-foldable-portable-solar-panel-charger-black-236561#.VQfmG_mUexk I carry one of these with me, along with a portable rechargeable battery for my phone when camping/hiking. In total weighs about 2kgs. It does take about a full day or 2 to recharge the battery enough to use the phone with these panels though. I'd imagine your radio uses much less power than my android phone.
Rest assured, we'll be finding an adequate replacement for payback! We will strike swiftly. Beware:
~~It could be "Leather Punch Pliers"~~
More likely it is Watchmaker's pin removing pliers
It's a random Chinese bike light like this Magicshine. They usually come with a crappy battery pack and unsafe wallwart charger and can be found under $30 if you look around.

Super happy with it, it's nice and powerful.
I think it's a bluetooth pedometer that is missing its wrist band. It looks very similar to this one in the picture where they remove it from the wrist band to charge it.

This is my 486 DX2 66 MHz with 20MB RAM, Cirrus GD5428 1MB and SB16. Got this computer not that long ago but it means much to me because my first computer had the same processor. I've been mostly playing Blackthorne, Sim Farm and recently began on Police Quest Open Season (ofc I got stuck almost immediately but i'm not going to use a walkthrough before I start pulling my hair of my head :P).
I don't know how many hours I have been using this machine but most of the time I have been installing stuff and configuring it (DOS 6.22 and Win3.11, editing autoexec and config and installing new and old stuff like CTmouse and 4DOS).
Also I have been planning to buy a Compact Flash to IDE like this one http://www.dx.com/p/cf-compact-flash-card-to-ide-40-pin-adapter-w-rear-pci-slot-panel-max-32gb-93248#.VtnQhdA5GQY to replace the harddrive.
Another project I have been planning is to make a Raspberry Pi to a WLAN bridge so I can connect my 486 to my wireless network.
Oooh, looks like it's a magnetic play doh/silicone grease. example
There should be a magnet inside the goo.
I have that exact USB fan featured down the page. Cost me $10 at DX way back in 2010.
...I sure wonder where the rest of the products come from...
These are the ones I ordered. The price seems to have gone up by 70cents since I last checked.
800M (DX has these in more colors, but they come up with a different search)
AWEI's website for more products and descriptions. Note the funny way chinese people decide to name their products.
Might order a few more of them tonight.
I love arduino projects. As a side note, if you don't mind waiting a month for parts... http://www.dx.com/s/arduino?category=436
Microcenter, if you have one near you is also a good source for parts.
I got them from a local store. The owner recommended (I'm in Pakistan) but here's what I got from Google.
Holy fuck, your dad has one expensive flashlight.
I bought this one (not very expensive) and two rechargeable batteries for another 10 bucks. I already had a charger that could take such batteries.
Let me just tell you, this thing is BRIGHT. Like, really powerful. Drains the battery in about 2 hours, which is a bit disappointing, but it's SO BRIGHT. Really surprising, considering that it fits easily in my pocket.
Then you focus the beam and it is like a wide square laser, easily goes 300+ feet, illuminating everything in its path.
All CPUs had pins on them until half way through Pentium 4, but that's not a P4 either because it doesn't have enough components in the centre.
Edit: But it is an LGA 775 so it's about 10 years old.
Edit 2: found it http://www.dx.com/p/intel-core-2-duo-e8400-3-0ghz-4m-lga775-wolfdable-desktop-dual-core-cpu-silver-golden-215161#.VzAtknPmjbs
I had a Nokia Ngage for nearly 10 years and I absolutely loved it, despite its many shortcomings. The landscape has changed though, and I don't really think there is much need for a phone with dedicated hardware, since the third party options work very well and are not too expensive. I have this controller and it works flawlessly with all emulators I've tried.
Earlier today, I tried to take a picture of the crystals on my tobacco flake. It kinda worked, but really, it sucked.
Tonight, I rigged up a platform to keep the pocket microscope steady, and with a "helping hand" tool, a better light source. I hovered over the eye piece with my point & shoot in macro mode, and got some better shots.
I'm not going to win any prizes over these, but I thought the piping community would have some interest in seeing the results!
It's one of the cheapest phones on the site that still has 512 MB RAM and the only two cheaper don't have light-up capacitive buttons. However, it is a refurb.
Dealxtreme's cheapest phones seem to be mostly Samsung knock-offs running Android 2.3 (lol) or have ridiculous specs like 512 MB internal storage. And they're still more expensive. And very likely don't have light-up capacitive buttons.
However, I did find a Gionee phone on SnapDeal for rs 4000, which is like $80 Canadian. Still a lot more expensive .. but it does appear to have light-up buttons. Yay. Unfortunately it's running 4.3, which is probably the worst version of JB you can run on a phone with limited RAM .. it's the version right before Google optimized Android's RAM usage with 4.4.
thanks, this is correct. I now found the exact one here. Although designed to spin, the ones in my picture definitely did not. Solved!
u mean this?
I'm sure it's been reversed engineered already...and since writing firmware is part of my day job...BRING IT.
edit: just ordered three. TRY TO STOP ME.
7/30/15: Just received two of them (third was cancelled for some reason). Man, these are nice! Folds flat, then gaps between in keys are filled by sliding the pieces together.
Looks like the interface is just RS232, so I'll probably make or use a module based on the TI CC2541 Bluetooth LE chip that has a little microcontroller with uart, and flash, that supports HID!
Mossberg 500 w/tactical (pistol grip) stock, eight round magazine extension, and high lumen tactical flashlight/laser.
Cost would be approximately $400. Luck.
I saw the kinds you were using, and recognized them. I have the same/similar daisy-chainable LEDs, and with a wireless remote have them rotate colors around my bar at home. They are awesome, and for the price really can't be beat. Since they're just kinda stuck under the bar, you can't see the strips.
I use this controller from DX.
Here's a starting point http://www.dx.com/p/2-8-lcd-touch-shield-module-for-arduino-leaf-maple-raspberry-pi-blue-318034
the elecfreaks LCDs are great. There are TONS of similar screens on ebay for similarly cheap prices.
I see you found how to do it as you asked but if you want a more permanent solution you can buy some cheap ass usb wifi dongle for less than $6 shipping included.
I'd never been to DX.com, so I checked it out just now. The first thing I noticed after the questionably cheap electronics was this lobotomy tool.
Here you go, cat shaped ball point pen.
This is correct.
I can open the magnetic locks on my liquor cabinet (very similar design) with the small rare earth magnets I use on my fridge.
I recently bought a Weloop Tommy and am very pleased with it. Altough its from dx.com, the battery life is good (around 2 weeks) and notifications and different watchfaces are pretty solid as well. DX link
The Rimei Razor is the king of inexpensive "giveaway" razors. They are less than $4 shipped from Deal Extreme, come in a nice little carrying case and more importantly they are much higher quality than their price would suggest. The handle and cap are made from chrome plated brass, and the baseplate is chrome plated stainless steel.
These razors give a really nice shave, equal in quality to razors costing 5-10x the price.
Occasionally there are some QC issues, so if you decide to buy them you may want to pick up an extra just in case you get one with a bent base-plate or something.
quite a basic cam. plus only available in US. vey less features
I am searching for last 1 month in Mumbai stores, impossible to get one.
finally ordered sj1000 from dx.com from HK. it is with customs now. costs 5.5k http://www.dx.com/p/sj4000-1-5-tft-12-0-mp-2-3-cmos-1080p-full-hd-outdoor-sports-digital-video-camera-black-288812
quite a few people have used it decided after this review http://www.team-bhp.com/forum/product-discussions/148338-sj1000-action-dash-camera-extended-review.html
Is $2.25 cheap enough? On the same site they are selling a USB C to HDMI, VGA, and 3.5mm converter for $20. (and yes, all prices are with free delivery)
Yes, these are probably not that good, but the idea that $20 is a normal price is really not true. Is the $20 one really 10 times better?
I go trail running quite a bit.
Earlier this week I wore my mountain bike shorts that are kind of like more athletic cargo shorts..anyways it has belt loops, so I just ran with my appendix holster on like I would normally wear it.
I used to throw my gun in my camelbak for runs, but I still hate having it off of me, even in the woods.
That solution works for me, so it might work for you, too. My Glock gets completely doused in sweat, but whatever, doesn't matter too much.
Edit: These are the exact shorts I run in.

Put some Nvidia stickers on the fans and everyone will buy it? ;) Seriously, i thought nvidia just started selling their very own cards with the latest generation (1060-1080). Any other manufacturer would probably not use any nvidia sticker on their own version of that graphics card wouldn't they?! Not to mention the text on that stickers looks just like the worst fake ever ;).

I run a sino-red dot on my 10-22. It's a rip off Aimpoint Micro. It holds zero, has red and green dots. It was $25. I cannot remember if I got it on AliExpress of DX, but it took a few weeks to get here.
Lets be honest here, for a red dot, where the only need is to super impose a red LED on a piece of glass, you don't need to go crazy. Most of the low end red dots are made in China anyways, so do some searching on AliExpress and you'll find one that you like for stupid cheap.
That being said, if you want magnification, buy better.
::edit:: Here this is what I bought. Price has gone up with weaker loonie. Works just fine. Easy to zero. Holds that zero. Two colours of dots. If you want to spend more money, shop around. But really, the low end red dots are all made in China. Don't pay for the brand name.
and what about steel and dazed who apperently both play with it?
edit: dazed also made a video there he compared most common competetive mice and decided in the end for the finalmouse. https://www.youtube.com/watch?v=YSHZXoizjw0

Thanks! TL;DR: Axially magnetized. N40. Manufacturer in China, interested in getting in touch?
These are actually axially magnetized, the picture is a little misleading as that is the best way to stack them neatly and handle. Our office has a lot of assembled Magination-pieces and a lot of prototypes, so when the other magnets are stacked like this, their total "outward" magnetic field is not that strong. So they pull on each other rather than all the other pieces and magnets we have laying around!
These are N40, and we have done tests with N35 to N52, and we haven't really seen any improvement in the overall functionality. For the final game I believe that we will go for the N35. The magnets are protected in a relatively large encapsulation, where a final Single piece is 22 * 5mm to a 20 * 2mm (d * h) magnet.
We started with these: http://www.dx.com/p/super-strong-rare-earth-re-magnets-20mm-x-2mm-100-pack-13515 but compared to the new magnets these are weaker and fragile. DX inform that the magnet grade is N33, but the new N35 magnets we have are a lot stronger. That's either DX-quality, or our manufacturer got us some of the same N40. Should we really feel a significant difference between N40 and N35 for magnets with this size encapsulated in plastic?
We got a great manufacturer in China for these magnets. They usually make magnets for sound systems, but have started to expand somewhat now. Are you interested in getting in touch? You might want to have at least 3000-5000 order quantity. We first got 3000-ish to test and prototype, and then 7100 for a pilot-test. Next we will order for the Kickstarter backers, so that's hopefully going to be a worthy order :)
Thanks for commenting - It brought me back into the thread.
He has commented with some information including a wiring diagram - but basically he used one of these.
I had no idea you could bluetooth anything for $5. This is awesome.

I've bought this dropin for my mag 4D. It was easy to fit with some small modding (mostly connecting it) and it works great with 4 D cells. Bright as hell, probably 1000ish lumens.
Don't know if this helps, but if you can get to an AutoZone, they'll lend you one for free. You may have to pay a hefty deposit, but they'll refund it when you bring the scanner back. If they say they can't do this, try sweet-talking the manager.
I'd offer my scanner up, but it's in my car which is sitting dead at my mechanic's.
And for future reference, the combination of a cheap bluetooth interface with the Torque Android app is a great tool to have around.
If you want 200 of them, Ali Express ;)
Edit: DealExtreme has more reasonable quantities.
Or if you just need something to hold cables to the wall, there are lots of other more attractive options: self adhesive cable clip
Without direct evidence, Ie, Dashcam. (point it toward the point of impact) It becomes a case of he said, she said. Nobody wins and even in small claims court, paint colour transfer is not proof. It is better than nothing, but you won't win.
Something to consider about dashcams. Some models have motion detection. But.... in most cars today the cigarette jack dies when you shut down the car. Dashcam batteries last maybe 20 minutes. So you need to connect the dashcam to a live 12V source after the key is out. The new problem then is the camera draining the car battery so you need one of these....
This item will power the dashcam until the car battery hits 11.8V and then it shuts down the camera.
BTW, here is an excellent thread on what is considered to be the best dashcam available for under $100.
Since I have been partaking of Easter wine, this just dawned on me. A cheaper method would be to paint the impact area in UltraViolet paint. It is clear. Then buy a cheap UV flashlight and you have your proof. But it may not be good enough for a court since you could just apply the UV paint to the victims (excuse me, perpetrators) vehicle.
Time to put down the bottle.
Most places sell them for $10 or more, but you can get them for less than half of that online at places like dx.com. Their selection rotates frequently, but they've had the "manateas" and other animal ones quite frequently for about $4 with free shipping from China.
I've bought many lights from Aliexpress and Dealextreme, they all work quite well. The middle one is my favorite, it's incredibly powerful and it only costs around 5 euros.
It uses one 18650 battery. I strongly recommend buying the batteries locally from a reputable seller because chinese cells are usually very shitty and die quickly.
Ha! Found it. That's one of the SKUs anyway, I can't find 112255.
Hard to believe that you can get such amazing high-quality knives so cheap. I'm almost tempted to buy a set. That works out to about $10 for just the peeler though, since you can get this other set with just the knives for cheaper.
That set isn't featured in the video though, so what's the point?
Edit: All right, I ordered a set. I expect these to bring enjoyment to me and to my whole family.
I've got a green laser pointer pen. I was ordering a few things from DealExtreme, spotted it on the site for a few bucks and thought "hey cool, I've got a red laser pointer, now I'll have a green one too". It's this one.
It's fuckin' bright. Like, it hurts your eyes to look at the dot if you shine it on a wall, especially if it's dark indoors. I can point it at a wharf across the bay from my house at night and make out the dot. I don't think it's got the power to permanently damage your eyes, but I'm sure if you had it aimed in your eyes you'd be seeing spots and unable to do anything for a while. You know, things like read the instrumentation on an airplane you're about to land.
But if you're not convinced, I propose a test. We'll meet in a Tim Hortons beside a busy street at night, I'll zap you in the eyeballs with the laser pointer, and you have to take a left out of the parking lot without getting T-boned. Best of luck.
Thanks for posting this. I'll also mention another cheap PIR option that works great if you have a Zigbee radio anywhere. It's the Xiaomi Human Body Sensor
I use it with my SmartThings hub and it works perfectly. Xiaomi also have a gateway that is supported in Home Assistant.
These are a little bit more money but the form factor is smaller and quite a bit nicer, imho.
Se é pra perto (Grau positivo, pra leitura), a DX.com tem alguns, e eles aceitam nosso antiquado boleto brasileiro como pagamento:

Eu preciso pra longe (Grau negativo), pedi da eyebuydirect.com, como não tinha cartão na época precisei um malabarismo pra conseguir colocar uns dolares no Paypal pra pagar, mas compensa já que no BR só óticas vendem lentes de grau, e cobram algo tipo o triplo do preço de fora nas versões mais simples (Comprei algo por uns R$ 60, que aqui sairia mais de R$ 160)
E talvez valha a pena experimentar lentes, as de poucos meses são baratas e muito ecommerce vende sem receita (Tenho o mesmo grau a 20 anos, chance ZERO de eu fazer novos exames a cada poucos meses só pra ter receita). A cada 3 ou 4 anos eu tento, mas nunca me acostumei com lentes.
>isn't that just the pc speaker that beeps when it's turned on?what makes you think a speaker that tiny could reproduce any low frequencies?
You obviously haven't seen one either? Why would you ask him about tiny speakers when you can't even see the difference between the speaker in the picture and your beep speaker?
I'm not sure about this site but this is the first thing that came up when I googled.
Specifically for the battery. Not sure about other parts.
Edit: http://www.dx.com/c/consumer-electronics-199/video-games-187/nintendo-ds-604/repair-parts-and-tools-635 can't speak to quality of this site though.
That is just a Siberia v3 dressed up to be a Fallout theme. The Siberia v3 as far as I know has a 3.5mm connector on the end. In theory it should correctly. If you want audio controls on the controller then I would recommend getting a chat adapter either the MS one or Turtle Beach one.
Worst case scenario is if they dont work out of the box you will need a OMTP to CTIA connector such as this one:
Here is the xbox page on headsets
There are a lot of them out there like this 5" one. But it doesn't have the resolution you're looking for (and it's not an assembled monitor, you'd have to build it into something). At that size, I'm not sure you'll be able to find anything 800x600.
There are also smaller ones like this 3.5" model. You would need to use an S-Video to VGA adapter though and again it won't have the resolution you need.
If you're willing to go a little bit bigger, there are a lot of them in the 7" range that include a VGA port and support the resolution you're looking for. Like these.
Not sure I'd trust my phone with that. It looks kind of light weight. But if you want to get that phone mount, you can get it here for $5. Shipping from China. Will take a while.
Or here for $4 (ebay)
Xiaomi i Kina gör bra grejer. Har deras 16 000 mAh powerbank och de har nyligen släppt en på 20 000 mAh, beställs fraktfritt härifrån: http://www.dx.com/p/xiaomi-20000mah-dual-usb-mobile-li-ion-power-bank-white-421190 till ca 300kr.
Kan även rekommendera deras bluetoothhögtalare, riktigt bra ljud för en väldigt billig peng.
Why is it horribly written? How about this sentence: "If you have a low budget and want urgent perfect razor regardless that it’s made from plastic, then Wilkinson sword classic is a good choice." If English is your first language, you should be ashamed of yourself.
Why is it wrong? Let's try "Lord L6 is the cheapest metal razor you will find in the market." Um, no. And the RiMei shaves a helluvalot better than the Lord.
I could go on (and on, and on) about how bad your blog post is. Obviously, though, you're just trying to draw clicks so that people can follow them to your sponsored links. I sincerely hope that doesn't happen. Because bullshit like this should not be encouraged.
I own a pair of these and have had a great experience so far. Bluetooth connects instantly to my phone (iPhone), Siri works perfectly, phone calls are surprisingly good quality, and the intercom connects automatically when you're in range with another paired device.
My one complaint is that the included helmet mount broke after awhile, so I ended up using the included 3M VHB sticky pad to mount it instead. Works fine now.
Also... shipping took like 5 months (ordered in January, got them beginning of June) to Canada, so beware of that. They shipped from Sweden.
For reference, purple(Blu-ray) lasers are 405nm, common blue lasers are 445nm, direct diode green lasers are 520nm(First produced around 5 years ago), Diode pumped solid state(dpss) green lasers, the ones that use crystals, are 532nm, red lasers are 650nm and infrared lasers are 808nm.
A diode pumped solid state green laser uses an 808nm laser diode and two different crystals to produce coherent green light. The first Crystal pushes the light further into the infrared too to produce light at 1064nm wavelength. The 2nd Crystal is a frequency doubling medium which cuts the wavelength in half, resulting in green light with a wavelength of 532nm.
Self levelling green lasers have been around much longer than direct diode green lasers have been around. So to answer OPs question, the more expensive self levelling green lasers that likely used dpss(crystals) green lasers are very difficult and time consuming to produce with any precision.
A cheap green dpss laser pointer like this one:
is thrown together as quickly as possible and the laser beam being emitted may be "off" by as much as 20°, and depending on the quality control of the manufacturer, could be the size of a tennis ball at 100 feet. This is called poor divergence.
For a high quality and precise green dpss laser, it would take higher quality lenses and crystals, and it would have to be tuned and calibrated manually by the manufacturer in order to produce a laser beam that is aligned properly and doesn't expand(diverge) too much.
Direct diode green lasers are coming down in price, so the price of red versus green self levelling lasers could even out in the next few years, but likely won't because of greed.
I don't recommend a cap. If you have existing LED wiring it may be current limited so you are overloading it with the relay requirements (~130mA instead of 30mA), worse than this the circuit is probably designed for simple loads, not nasty inductive loads.
I suggest, if you must use this line you use an opto isolated relay like this one http://www.dx.com/p/jtron-1-channel-opto-isolated-relay-module-isolation-module-black-270934 because it presents a load that looks like an LED.
you can find more details here including a circuit diagram: https://arduino-info.wikispaces.com/RelayIsolation
The circuit functions like this (remove jumper): When the lights are on the LED in the opto-isolator lights up the internal transistor and makes it conduct. Unfortunately this only allows small currents to flow so this signal is passed to the base of another transistor (Q1) that acts like a current amplifier boosting the signal upto a level where it can switch the relay. The final circuit feature is the diode which crosses the coil of the relay, this diode deals with "back emf" which is the sudden voltage spike that a coil will create when you cut the power (see nasty inductive load comment)
I didn't mention it, but I do have one in the cooking kit. I'm pretty redundant on firestarting mechanisms. In my camping bag I have a bic in a waterproof container and one of these shitty firesteels. In my box I have my zippo, and there's a matchbox in my coin drawer.
I'm using alcohol-based Interflux IF8001 in my videos. Search eBay for it, and you'll find some sellers that have small 50ml bottles.
EDIT make sure you get a needle bottle as well
I just bought my first GoPro and I'm also looking for this. There are $2 clips on eBay but they look cheap. The GoPro clip linked here looks a lot better.
Peak ones to but it's too pricey for me. Here are alternatives I found
I don't know which I'll get.
uh, it doesn't really get much wider. You'd be looking at a full on fish with huge vignette
You'd need something like this http://www.dx.com/p/highpro-0-38x-super-wide-angle-fish-eye-lens-for-gopro-hero3-hero3-black-273159
warning: never shopped there, may be crap but thats the kind of thing you'd need with an adapter I'm sure. I used one way back in the day with 35mm film and they're really not very sharp
Täältä hyväksynnän hylje tuolle RiMei höylälle. Pysyy lapasesa, on jämäkkä ja sopivan painava, ja vaikka terä onki enempi esillä ku joisain muisa malleisa ni en ainaka ite oo vielä onnistunu kertaaka töpeksihän naamaani auki sillä. Jos kotona on jo arvokkaampi aparaatti, ni tuon voi tilata vaikka matkavehkeeks. Jos tykkää ajatella tuotteelle jotain päivähintaa tai käyttökertahintaa, ni joku 30e jostain maailman tappiin asti suvusa kulkevasta höylästä ei välttämätä oo kovin kauhea hinta.
Edit: ja lisätään tähän nyt vielä että ihtehän oon atoopikko ja naama kukkii välillä ja kuivaa helposti, mutta iho ei ainaka huonommaks mee ku mitä braunin sähkösuristimella tai Gillette MacStealthUltraActionPro 5-BladeTwinTurbo höylillä. Iteasiasa väittäsin että pysyy jopa parempana ku tulee ajettua varovaisemmin ja hoidettua täsä ajamisen yhteydesä samalla helpommin.
I would use a charging module like this: http://www.dx.com/p/tp4056-diy-1a-micro-usb-li-ion-battery-charging-board-charger-module-blue-373990
This one even have a micro USB port on it, so you can use any phone charger you already have. It charges with up to 1A, which is perfect for a single 18650.
$5 tire repair kit, compressor, condoms, water, space blanket, quick detailer and microfiber, flask of bourbon, various phone chargers, headlamp, 2m/70cm HT's, OBD-II scanner, emergency cigar, ...
I'd recommend getting a 2A phone charger to charge it. I found this site which states a 9 hour charging time, probably using a 2A charger. (1.2A is really slow and yes, USB standard is 0.5A from a computer or hub) I wouldn't be surprised that your charger gets a bit hotter, that battery is a lot bigger than your average phone so the charger has to supply power for a longer time to fill it up.
You need a better USB car charger. Spikes on your 12V should not make it on to the 5V output. The caps on the coil side are for tuning purposes not for decoupling/storage.
For reference I've been using this for over a year now and I haven't had any problem with it.
