Well, now's the time I make you all feel better about yourself. I stopped by my local electronics store and picked up a diode. I put it in the circuit and it still had the same problem. Turns out I had gotten a zener diode which will do that. I was resigned to a second trip to the store when I recal...

Okay, I have an actual question with which, hopefully, someone can help me. The audio amp I'm using I got at Wal-mart out of a device for kids' bikes so they can listen to their MP3 players. The problem is the signal in/out is supposed to be a separate power supply from the main amp circuit. When I ...

So I have managed to hook up a screen. It works and I learned a bit. http://i1146.photobucket.com/albums/o521/theantithesis/HNI_0038.jpg As you can see, I have an adafruit powerboost and a lipo battery attached. I had tried to hook the screen up directly and it worked, but the screen would flicker b...

I'm planning to turn my Velleman MK191 Classic TV Tennis Game with Analog Bats into a semi portable pong system by implementing a screen and 3D printing a case. https://www.quasarelectronics.co.uk/media/ecom/prodlg/velleman-mk191.jpg For those unfamiliar, the MK191 is a soldering kit. I'm not entire...

I tried that. It didn't work. It rebooted the pi immediately when plugging in anything. I think the usb hub has more to it than just wiring multiple ports. Probably sending different instructions from different devices to the computer. Quite right. I have a cheap hub from Big Lots and it has a MA86...

I would like to see a non-game related project. I love retro games, but it's all I can think of to do with a Pi. I have three different models and I loaded Retropie on all of them. So, how about something else to get my mind off of retrogames. Maybe a home theater system that is also portable so you...

So, here's my set-up with the hacked Pigrrl. http://i1146.photobucket.com/albums/o521/theantithesis/3ds%20033.jpg What I've got so far works except there's a couple vertical lines on the left side of the screen as shown here: http://i1146.photobucket.com/albums/o521/theantithesis/3ds%20029.jpg http:...

As is typical of such things, as soon as I posted, I continued to google and found a nice post on another forum that explained this and a link to a datasheet for an audio socket. I'll post what I found for those who may also need help. http://i.stack.imgur.com/Yjl5u.png http://i1146.photobucket.com/...

So I'm building the Pigrrl 1 kit from Adafruit because I want to build a couple projects before attempting something like the Gameboy Zero. I'm not doing the kit as written. I've already soldered a 3.5 screen to it, eschewing the PiTFT the kit came with. (I'll find a use for it elsewhere.) The kit j...

I have used aluminum foil to make a gamepad once. There was a Youtube video where a kid shows you how to make a gamepad using a microcontroller from an old keyboard. (My attempt was a story of colossal failure, but that's for another day) The video can be seen here, for those who are curious: https:...
