The final part for Hydrobot 1.0 has arrived! A couple of months ago, Nate C. from Heatsync recommended the MCP1460 DC/DC boost converter. It can boost at least 0.6V to 2V, 3.3V, or 5V.I'm using it to amplify the 0.935V and 255mA to 5V to power the Arduino using hydrogen (Sweet!). I found a tutorial online that went over how to build a DC/DC boost converter out of off the shelf parts, but this Microchip development board has a smaller footprint than building it. I can't wait till Monday to go to Heatsync and solder it to the fuel cell and power my Arduino off of water!
