Martin Raynsford shared detailed instructions of how to make a DIY Heng Lamp, project instructables here:
The HENG Balance lamp just successfully funded on Kickstarter, the design is pretty cool and unique so we decided to make a copy of it. At it’s heart it’s just an LED lamp with a simple micro switch to turn it on and off, we had all the parts to hand and a laser cutter to make the more complicated bits. The lower magnet is pulled towards the upper magnet and that turns on the micro switch.
