I this USB-Serial CP2102 6pin version US$1.25 - It fits my P8XBlade2 by just bending the DTR pin to the next 0.1" position. This is shown on the Parallax Forum.http://www.ebay.com/itm/6Pin-USB-2-0-to-TTL-UART-M...If you use a P8XBlade2, don't forget you may need to enable the WE to the EEPROM (solder link), and you will need to solder the QE link (enables the onboard transistor reset circuit from DTR) if you use a non-PropPlug USB-Serial otherwise you will need to solder the other side of the 3pin link for PropPlug compatible.
Very nice project. Congratulations!!!I love the idea of 3D printing the ring for the LEDs.
