How to Measure Planck’s Constant Using Lego

* Plus several hundred dollars of non-lego equipment.

I strongly suspect a working setup could be made for <$50 in electronics parts.

The LabJack ADC, Phidgets DAC and Photodiode make up nearly $450 of the total cost. An Arduino, breadboard and a few components could probably do the same for a whole lot cheaper.

The concept of "low cost" here is relative to a dedicated lab watt balance machine, which is probably thousands of dollars.

Exactly, plus the actual stuff that makes the measurement.

Yea. A really enticing title. But disappointingly complex.
