Parts to order and why…

Need

3 pin female header (1x3) - To build sensor end of wiring harness to connect to Parallax sonar sensor.
100uF capacitor (Digi-Key part number: P803-ND or equivalent) - To eliminate dirty power to MaxSonar EZ1 ping sensor.

Want

MaxSonar EZn sensors - Smaller, lighter than Parallax sensors. Narrower field of operation. Although Parallax version can read <5" -EZ1 cannot read closer than 6".
tri-color LEDs
Tiny LEDs for final prototype board - take up less space.
Shorter NXT cables - Easier wire management, save weight.
