This converts a PS2 controller into a MIDI controller. The current firmware supports remapping of the buttons to different notes or controllers. It’s based on a PIC microchip–full, explained source code and instructions for making modifications are supplied. [more]

Demo-application for Philips LPC2000 ARM7TDMI controller with a KS0108/KS0107-based graphics-LCD (128*64 pixels), DCF77 time-receiver and Onewire-Bus (for DS18×20-Temp.-Sensor).The time and date are received with a DCF77-receiver-module .The DCF77-signal is transmitted from a station near Frankfurt/Main, Germany and can be received all over Europe, North Africa and the Middle-East.

This schematic is ment to digitally display the output of my electronic Swissflow SF800 flow sensor. This sensor puts out an open collector square wave signal (like a fan RPM monitoring signal) between 50Hz and 2000Hz . By dividing the measured frequency by 10 and putting the decimal point at the right place you get directly a display in liter/minute.[more]

his is a student project from Cornell University.It designed by Reid Gurnee.He writes:
My senior project is to design and build a digital oscilloscope for Professor Land. This project involves a number of design challenges. On the analog side, I need a fast, low noise A/D converter. In addition, the circuit requires a -20V bias from a 5V supply. In the realm of digital, it involves interfacing two micro-controllers with each other, an LCD display, and an analog to digital converter. With such a broad range of challenges, I searched for help from my professors and contacts I made on the web. I was successful in getting help on floating point arithmetic for an 8 bit micro-controller and LCD interfacing.
