JDM2 PIC programmer

The previous PIC programmer that I posted only programs a PIC16F84. You may want to build a PIC programmer that will program a higher variety of PIC chips. Ian writes: …Prior to reading sites like www.hackaday.com & www.makezine.com/blog I had worked only with the Amtel/AVR line of microcontrollers. After seeing all the cool projects people [...]

Video signal generation with PIC chip

The idea of creating video signals with a microcontroller is very fascinating to me. Creating live video data through software is not an easy task. The task is even more complicated if implemented on a PIC chip. The video signal has to constantly be generated, and any calculations have to be done during a small [...]

Run out of pins on your PIC chip?

I remember when I was building my line following robot that I ran out of output pins. I was using two sensors as inputs, and just didn’t have enough output pins left to control the motors the way that I wanted to. Here is an article on how to make an external multiplexor that will [...]

DIY Line Following Robot 2

Introduction: Well, I have finally had a chance to get over all of my finals, and hopefully did well. I will find out on Monday. Well, as I have promised, here is my next DIY how to project. Beware, it is going to have to be in depth, and long. As any good engineering project [...]

Solder with toaster oven

Here is a DIY project that lets you solder those tiny surface mount pins on a microcontroller. You can use solder paste on the board. You place the component exactly in the right location, and then stick it in your toaster oven. It will activate the solder in the paste, and it will ball up [...]

DIY pong game

Well, here is yet another cornell project. Why am I still using them? Because they are cool, and complex, and I really want to make one of these. They use an atmel mega 32 microcontroller. They program the entire game, including the video output to control a television. This is the game that I would [...]

Build your own Microcontroller programmer

Well, this is a pretty neat DIY project. Not super useful these days when you need USB. I have a laptop, and that is all I have. Otherwise, here is a project so you can build your own microcontroller programmer. It is neat just because it can be done, and maybe if you make your [...]

How to make your own Duck Hunt video game

This is one of the coolest things that I have seen in a while. This is way beyond my abilities, of course, I have never taken a class in video output. These guys for an electrical engineering assignment at cornell university, reproduced their own version of the old NES duck hunt. They used two micro [...]

Robot follows black tape

Here is a website that makes a robot that will follow a line of electrical tape layed down on the floor. This is similar to one I made in undergrad. If I can find my notebook, I might put up how I did it. I do have a video of mine somewhere, also, but no [...]

Build a Gps

Here is a how-to project for making your own GPS. This guy takes a LCD from a cell phone, and a GPS unit, and makes everything he needs for his own personal GPS. It seems hard, but what a challenge. [Link]
