Sump pump Monitor My parents have a cistern and a sump pump which would be useful to have some sort of water level monitoring. In the past, we would check the cistern level with a pressure gauge calibrated in inches of water. There was a rubber squeeze bulb which which would pressurize a plastic line which fed into the cistern, and the resulting level would be shown on the gauge.

MySensor board After reading about the MySensors project, I decided to design a small circuit board to hold the Arduino and radio module. Status: * Nov 25th: I've assembled two working boards. Imgur photos * Nov 24th: I received the boards, Yay!! * Nov 7th, 2014: I'm waiting on the PCB's from

SD GPS Track Logger Why? This is why:Bicycling Trips ICSP Connector Need a PIC18 chip with more memory, I'm using the PIC18F4685 with 96Kbytes of program memory. Microchip Mass Storage Class Firmware [Still not working] Still not working. Might be software or hardware, I'll need to check it on a digital oscilloscope. Correct clock rate (less than 400KHz).
