More recently, we’ve seen ARM Cortex kits for $10-$50, the flowering of the whole Arduino ecosystem, and of course, the Raspberry Pi. It’s microcontroller heaven with very many dev boards available. You you want more performance, there is a wide selection of

Measuring the Plank Constant With Lego

Something for the weekend: Measuring the Plank Constant With Lego tells how you can do science experiment with LEGO. A Watt balance looks like a double-armed scale where one weight can be compared to another weight of known mass. Instead of using two arms, a Watt balance only has one arm, brought into balance by a
