USB data killer

thingiverse

Rather than making it sound too dramatic, I merely required a cable that would let through USB power but not data signals. To control my homemade clock using a Stellaris Launchpad, I discovered that sometimes, I accidentally flash the firmware over my clock's system. While there might be software solutions, I opted for a quick fix. To achieve this, print the STL file (containing both halves), solder a USB female socket to a PCB, and attach the power cables of a cut-off USB cable to the specified pins. Finally, fill the two halves with hot glue and press them together until they cool down.
