Propeller chip, tri-axial accelerometer, flexi-force sensor, & PING Sonar senso

The goal is to have all three sensors inside of remote control race car simultaneously taking data from model scale car crashes.

Each of my sensors listed in subject all have different voltage requirements. Is there a way I can power all of my sensors and propeller chip with as few as one or two sources?


FLEXI FORCE SENSOR
TRI-AXIAL ACCELEROMETER

PING DISTANCE SENSOR

PROPELLER CHIP

    Usually you will need a 3.3V supply and a 5V supply, both well-regulated. The Propeller needs the 3.3V. The accelerometer and PING need 5V. Usually, you can run the flexi-force sensor off anything you can run an op-amp off and that includes 5V if you choose an op-amp for that supply voltage. You could just copy the regulator chain for the Protoboard from the schematic where the 5V is derived from an unregulated 6 to 9V supply and the 3.3V is derived from the 5V supply.

    I will try this out! Thank you so much sir, this has been driving me crazy.
