Crazy stuff happening with my 16F877A. I can program it fine, and it runs. Right now it's running a program that blinks an LED, connected to port...
I have a PICkit 2 and MPLAB, and I'm trying to program a 16F877A. The PICkit 2 programming software identifies the UC correctly, and can read from...
So my tip for this nice little iron is pretty worn down. It had some fancy coating that wore off long ago, so I've been sanding away the oxidation...
So I'm looking to use a PIC for three channel PWM lighting control on a project. The PIC16F685, 690 would seem to fit the bill. 4 PWM channels...
*Long post! I apologize, but bear with me, I promise it has nice grammar and is easy to understand!* I have a project where I have red, green...
I'm looking to create an audio controlled PWM setup for red, green and blue lighting of a particular object (think a CD lamp, but way cooler). I'd...
CD lamps are cool, especially well-made ones that look like this. But they all have a few problems...they need cold cathodes, which usually means...
A friend of mine is building a (well, many) DDR pad, and is looking for the best solution to detect steps. Apparently the arcade versions are...
So the flyback transformer in my Samtron 75V has that annoying ringing sound. You all know it, and I want it to stop. My dad worked in TV repair...
So it appears I know how a lot of things work but I can never actually MAKE them work when I build them. Here's about the most simple NPN...
I can only seem to find NC relays that are "reed relays" on DigiKey. I realize there are probably quite a few places that have NC relays, but I'm...
Made with SketchUp and hosted by ImageShack. [IMG] [IMG] [IMG] [IMG] The frame would be made of 1/2" wide, 1/8" thick aluminum angle, all...
My Circuit Theory I professor told us that as heat increases, conductors raise in resistance. Which of course is true. He also said however, that...
Okay, two things. First, anyone have any good tutorials on using BJTs for switches? I've built circuits myself that do this, it's easy, but I was...
Does anyone know of an epoxy or super glue which is a liquid? It would have to be about syrup-thick, thin enough to say, flow between microfins on...
I do all the time. I had a small bolt in some lineman's pliers, I was grinding it flat on my bench grinder. It wasn't a straight surface so I...
Hey, been lurking for a while and since I have something practical to say, I thought I'd register. :) I'm thinking of building some custom...
