William Garrido writes, “I released the USB Tester OLED Backpack today and thought it would be good for you guys to post up. It is an add on for the USB Tester for measuring voltage and current. With the OLED you don’t even need a DMM and can view the measurements on the OLED display and log them to your computer with the Java app.” In the above photo, the backpack is measuring voltage and current usage by a Raspberry Pi.
More details can be found in William’s post at Mobilewill. He is also seeking supporters for this project via a two-week fundraiser on Tindie. He says the source code will be available for download upon the project’s final release.
