Many of the useful tools and utilities you’ll find on this site are released as what I like to call CollegeFundware, which is basically shareware with a bit of a twist. You may use the software for a reasonable period…
This makes a great gift, t-shirt, mug, etc. for any computer or math geek, friend, child or baby! Write you name or message in up to 100,000 of the infinitely non-repeating digits of pi. Originally published: Mar 21, 2006. Introduction…
I suppose this doesn’t *need* the ATMega, but they’re only a few bucks, so what the hey. This uses an old GI SP0256-AL2 speech synthesizer IC containing all 59 English phenomes. It sounds very computer-like (even though the original documentation…
An even tinier 4-amp dual stepper motor controller and driver, providing 500mA per phase for two 4-phase unipolar steppers, or 1A per phase for 1 motor when signals are combined (separate input for motor power). Four-position DIP switches assign a…
NOTE: Each picture on this page has its own scale.BlueBot is a platform for autonomous robot experimentation, engineered around a specific set of motors. It’s in itself an experiment in mixing easy-to-find components and custom components, with the end goal being a well-engineered,…
A tiny I2C master controller designed to monitor and handle sensor loop and control operations. Conditioned power (+5V) is brought into this board, where it is coupled with the TWI for twelve external devices on three independent clock and data…
