Hackaday alum [Adam Harris] hacked an FTDI cable to use for programming his Arduino. After cracking open the plastic case he found the FTDI chip used is the same as the one in the SparkFun programmer. The only real difference was that his cable wasn’t resetting the Arduino, he had to do that manually. The solution was to reroute the RTS wire so that it connected up to the DTR pin. This proved difficult because of the tiny footprint of the chip, but after many tries he managed to get a piece of wire wrap soldered in place.
