LiPo Charger with Reverse Polarity Protection

LiPo batteries are cheap, high capacity and ubiquitous in portable electronics. Having a portable USB charger to top them up is extremely useful, but not all batteries are wired the same.

This board adds reverse polarity protection to Adafruit’s Micro LiPo board, protecting both the IC and battery.

Thermaltake 4x USB 3.0 Front Panel

The Thermaltake Urban S31 is a full featured PC case. It has several optical drive bays, a SATA dock, and four front panel USB ports. Two of these front panel ports are USB 2.0. With many motherboards having multiple USB 3.0 headers, it would be great if all 4 could be converted to USB 3.0.
