Motorcycle custom instrument panel
Josh from Colorado build a nice dashboard for this motorcycle based on ATMega128 and EPSON S1D13700 LCD Screen: Since the GSXR is now a street fighter the factory gauges won’t do, and I wanted something I could log air/fuel ratios with so I can jet the bike. I went a little...

DIY milliohmmeter
by hwmakers.eu: This is an example of a simple and cheap milliohmmeter that can be made by every maker. The core of the circuit are a current source (LT3092) and a current sense (INA225): a costant current flows through the milliohm resistor under test and the voltage at the current...
