Consisting of three 200+ lumen neutral-white Rebels, the spotlight puts a lot of light onto a spot on the workbench. I’m going to pick up a diffuser optic for the collimator so it’s not quite such a tight spot. [...]Fresh PCBs
Updated: 2012-01-16 01:04:47I just received these FedEX on Tuesday, fresh from China via Colorado. The first stack of boards is the prototype taillight driver, sporting a tilt switch for motion detection. The second board is a pretty similar design, with a bigger inductor and more compact layout. The intention here is to run a trio of Lumiled’s [...]
