KeyboardCowboy got a reaction from skynet1010 in Smart On/Off switch for pc using relay
OK, so here's my take on the whole mess. Well first things first, I think your idea is cool, whats your experience level with this kind of stuff? your expectations should match your acquired skill level. How much work are you willing to do? as far as I'm aware, there is no turn key solution to this sort of thing. How much are you willing to spend on components? I would shoot (pun) for around 50 bucks USD.
IOT boot switch!!!
Jumping (pun) right in, the 'jumper' interface.... solution, the jumper pins are standard 2.54mm pitch headers (double check me), if your wanting to run your switch in parallel as a redundancy, yes, do it! do it now!
2x2 headers
Jumper wires
So, after a bit of cutting and stripping, you could wire your mobo jumper pins to an off board controller, and connect your switch in parallel off board.
(I'm not even going to try and draw this in paint, use your imagination. I can provided graphics upon request)
Switching the jumper.... solution, the jumper pins need to be connected / shorted for at least 50ms to turn the PC on/off, longer just dose a hard shutdown, I think its 8 seconds? so... you have options. you could use a relay, an N channel Mosfet, or what I recommend is a SSR, solid state relay. You can expect to see .5mA across the jumper pins (jacked from Intel), well there about. A single pole, single throw, normally open ssr is right below, its though hole too. Now, the typical forward voltage of this guy is 1.15 volts @ 8mA, so I'm using a 261 ohm resistor. Refer to the image below (assumes 3.3v logic).
solid state relay
resistor
Controller board..... solution, I would recommend the 'HUZZAH32' , why? well let me explain. Its 20 bucks USD off the shelf. It has arduino support. It has an integrated lipo charger (alternative power solution btw). its supported by the 'fauxmoESP' library (more on that later). It has great documentation. It comes in black, my favorite color. It has micro usb power + charging + programing. Slap your TLP222A + hacked together wiring harness on the HUZZAH32, and your ready to go fight with firmware.
documentation
interfacing with Alexa.... solution, the 'fauxmoESP' library. So what the hell is that? exactly! Using black magic it connects your Huzzah32 board to Alexa. Its more complicated than that, refer to this tutorial here, there's even a sexy video. The linked tutorial goes over an example project with the fauxmoESP library. I'm not going to touch on the firmware bit, it would just take to long, if your interested, quote me and I can give ya a break down or help with your sketch.
Powering all the things.... solution... umm yeah a solution, that's really up to you. You have 3? options as far as I can tell.
1.) power it with a USB cable (connector on the board)
2.) power it from an unpopulated USB header on your motherboard. Use a few extra jumper cables I linked above (you get 20), the pitch is also 2.54mm.
3.) hack apart your power supply (not recommended)
4.) use a battery in conjunction with the molex power. If your pc is on more than its off, and you get the right capacity battery, *attacked by math* you should be able to battery operate your IOT switch given your current draw is low and the battery has enough time to charge between power cycles.
Your going to need a small prototyping board to solder all your wires and components to, yes soldering, its not that hard if ya have the gear.
I hope your project turns out well, let me know if this helped or just pissed ya off.

KeyboardCowboy reacted to Rune in Tempered Glass Etching - Overwatch Mercy
I recently bought an SL600M to upgrade from an aging 900d. I wanted something that was kind of unique that wouldn't compromise on performance, but was smaller than the 1000D because jesus christ my desk. After getting everything mounted properly, I began to make a stencil (first time) for a free mercy design I found online. Unfortunately made the mistake of using the wrong side of the vinyl like an idiot and had to use an xacto to attempt to save the stencil and more or less ruined the first go, but I think it ended up being okay in the end. I think, with some more cable management, this will be my best looking system yet Hopefully my next project will go a bit smoother.
Parts:
CASE: Cooler Master SL600M
CPU: 9900k @ 5.2Ghz
MB: Z390 Aorus Xtreme
RAM: Corsair Vengeance RGB 3600c17
SSD: 960 PRO 512gb || 2x Sandisk Extreme Pro 512gb
GPU: 2080ti FTW3 + Hydrocopper block
PSU: EVGA 850P2
RADIATORS AND COOLING: 2x EK Coolstream XTX 360 || EK Supremacy Evo || 6x Corsair ML 120 PRO Red
LIGHTING: Nzxt Hue+ || Custom Overwatch ssd covers

KeyboardCowboy reacted to YoFavRussian in Multimeter help
Did you investigate further inside the meter, I've seen where corrosion will leak into areas and cause issues with traces on PCBs. That would call for a trace repair.

....I mean...if you custom built you could get way better...but..if pre-built...its okay. I would definitely add a 120gb ssd for 20$
but...that same system..and systems like it(and better) are 100-120 USD shipped. in the US

Have you ever wanted to see a really bad CPU bottleneck? Like the kind where you can barely access half of your GPUs potential? That's kinda weird... but also this is the perfect video for you.
Buy a Titan RTX

KeyboardCowboy reacted to tsmspace in planning an arduino game controller
Thanks all so far. Vjoy runs my fpv transmitter , so its not completely alien to me.
I have a pro nano v3, with 8 analog inputs, and 14 digital inputs. I definately need two triggers per side, and a 4 button xyab on right thumb, but have to then choose between the remaining 4 buttons left, and stick presses. Basically, I think that the thumb presses are the easier ones, meaning i will axe trigger stick press first, thumb press second. ... but i can probably keep the thumb presses to make 14 digital buttons since thats all i will need to connect to.
Heres more pics of the layout. Wiring is be careful, but programming might take forever.....

KeyboardCowboy reacted to Hackentosher in planning an arduino game controller
I'll just leave this arduino HID library with gamepad support here https://github.com/NicoHood/HID...
4 Joysticks sounds like a lot to keep track of in your brain. I'm drawing a blank on what kinds of games need 8 axes of analog control but okay.
You'll need an arduino with a built in USB tranceiver on the chip, which limits your options a bit, but it makes the device act as a native USB gamepad. You'll need a board with either an ATMEGA 32u4, or a SAMD21. The latter is my favorite, but the 32u4 is more common and typically a bit cheaper. If this was my project, I think I would get an arduino pro-micro off ebay for $3. However, I just realized each of your 8 axes is going to need an analog input pin. Most arduino boards have around 5. There are two ways I know of to get around this: 1. i2c IO expander. The name says it all, you get more IO to your microcontroller using the i2c protocol to communicate the data between the chips. However, idk about analog support. The ones I saw on Adafruit appeared to be digital only, but you might be able to find an IC on Digikey or Mouser. 2. A larger board/chip that has the enough analog inputs broken out.
