Over at Darker Technologies they're making good progress on the Maker Faire projects that we're exhibiting in the same booth this May. The first LED grow lamp array has been built and tested. It uses red and blue LEDs, since those are the wavelengths plants absorb (they reflect green, so no need to waste power emitting that color). He'll be testing the arrays on live plants this month, using other light sources as a control. If you're in the SF Bay Area this May, stop by the Maker Faire in San Mateo and check out all the great projects and exhibits! There's a lot to do! It's fun!
