Things I've Built
3-Instruction Forth for Arduino
Contact me for details. This is a work in progress. It is what I have built to enable rapid prototyping/development of embedded/microcontroller applications. http://www.mathscitech.org/articles
Turtle Logo in Forth (1000 lines of code)
Full-featured Turtle Logo drawing program accessible to 4yo children written in 1000 lines of Forth (Windows).. Drive turtle using 3 keys, leaving a virtual ink trail. Algorithmic thinking. http://mathscitech.org/articles/turtle-logo-forth
RFID Proximity Sensor
8-foot perimeter proximity sensor driven by Arduino Nano interfaced with an RFID tag reader (ThingMagic) and a high-gain RFID antenna, interfaced with strobe and 100dB alarm. http://mathscitech.org/articles/microcontrollers-nano
13-key Purely Analog Musical Piano
13-key analog piano using a chain of 13 individually tunable astable multivibrator circuits with outputs connected to audio amplifier (LM386) and 8-ohm, 0.2W, 2″ speaker, 9VDC battery. http://mathscitech.org/articles/building-music-synthesizer
