=== Programmable Electronic Load ====

Use micro controller to read current from sense resistor and control the drive of multiple parallele power resistors.

=== Laser alignment ===
Attach laser diode/ pointer to xy stage and point it to a quadrant photodiode. Can use diff amp to get error signal from quadrants to move stage.
* need to find affordable xy stage.
* decide on dc motor vs stepper.
