The Siemens heating system is meant to work with intermittent electric power to take advantage of lower electric rates. The prior controller was analog, and used a capacitor to average outside temp and control the heaters. The heaters were...

This plotter was made in DDR, but didn't work even once since 1989, and was kept in its original package.Some bulged capacitors were on PCBs. All electrolytic capacitors were replaced with new one.This plotter is very heavy (16 kg), requires a lot of...
The first thing was to figure out how the keyboard worked. It's a standard matrix keyboard with an 8x8 matrix, for a total of 64 keys. This takes up 16 pins of a 20 pin connector. There is a 65th key, "Restore", that is on it's own, so another...

Wirelessly controlled chess clock, to save the motion of pressing a button: you save time, you save energy, and it looks cool... Just kidding.Recently i have joined a chess club at the google campus meetups, and as fitting for a meetup at the google...
Firstly, here's a diagram to clarify how the system is connected:In summary, the arduino converts the analog input from one or more (up to 8) sensors, concatenates the data into a 32 byte value, and sends the value over SPI to the NRF24 module. On the...
Driving the TCD1304:The TCD1304 requires the following input to functionThe master clock (fM)The shift gate (SH)The integration clear gate (ICG)The frequency of fM must be in the 0.8-4 MHz range. In this project fM = 2.0 MHz (but it is user changeable)The...
