[Modustrial Maker] is at it again with another seriously cool LED visualizer. This time around, he’s built pair of pendant lights inspired by the rings of Saturn.
The rings are made mostly of walnut plywood using a circle router jig to make the cut easier. If you are inspired to make these for yourself, [Modustrial Maker] is clear — the order in which you cut out the pieces of the rings is absolutely critical. The pieces are glued together — with any edges sanded smooth — and edgebanding applied using a hot air gun due to the curved surface before staining. Duplicate for the second (or more if you so choose!) rings. Be forewarned — a little geometry will be needed to find anchor points that will keep the rings properly balanced.
[Modustrial Maker] suggests an off-the shelf LED controller to handle the visualizations and lighting effects, but he used an Arduino Mega clone as the brains — code available here, a MonkeyJack MAX9814 electret mic, and a four-channel RF remote/transceiver to control the different modes. Pulsing along to the music, these rings make for sleek lighting indeed.

Standing at your desk all day is healthier by far than sitting, but the commercial options tend to be expensive. [drivenbyentropy] had to contend with a heater right where the desk would go, but building an adjustable office desk to accommodate it turned out — well — gorgeous.
Two 18″ heavy duty 12 V DC actuators raise and lower the desk with a 600 lbs static load capacity and 200 lbs of lifting load each. One actuator is actually slightly faster than the other, so instead of working out something fancy, [drivenbyentropy] simply extended the cable length on the faster actuator to disguise the difference.
Framed with some standard 2×4’s and sheathed with plywood, the massive four by eight foot desk has twelve ball-bearing drawer slides in the legs to add stability and smooth out height adjustments. Because of its size and having to build around the heating unit, the desk is stuck in the room since it does not easily come apart. There is, however, easy access to the two electronics compartments for troubleshooting!
