BUS PIRATE: pin order and cable colors

The Bus Pirate pinout was supposed to be intuitive, except for one Arduino-like mistake. Each protocol uses the same pin for similar functions, and the pins used are supposed to “walk” up the row. 1-Wire uses Master Out Slave In (MOSI, pin number 1). I2C uses MOSI (1) and CLOCK (2). UART uses MOSI (1) […]

Powerpole fused distribution board

There are commercial Powerpole distribution boxes available but they are very expensive and difficult to obtain in the […]

So I hacked this connector comprising a short length of 10 wire ribbon cable, a 5×2 IDE connector to mate with the BusPirate […]

Fragile connectors on the SparkFun Nokia knock-off

Fragile connectors on the SparkFun Nokia knock-off LCD are a headache. They’re not rated for multiple insertions, but we can usually move them very carefully on a final prototype. A mating connector we soldered must have warped from the heat. It ate two LCDs right away. On the right is the ‘good’ from a few […]
