    Power supply question

    I am attempting to light many 700mA LEDs (e.g., this) and am trying to figure out the cheapest/easiest way to power them in parallel. The Mean Well 90W power supply looks like a pretty decent solution based on preliminary research. However, I am still criminally ignorant on a lot of the...

    LED dome

    I was unclear. Although even illumination is a feature, it also needs to be able to light with different patterns for complicated reasons that I can go into if anyone is interested. The TLC5940 looks like it will work perfectly for what I'm trying to do. I'll update this thread once I get...

    LED dome

    I had figured that this approach would be more expensive, but maybe microcontrollers are cheaper now...

    LED dome

    The lights are inward-facing and white in order to evenly illuminate the center from all directions. It looks like I can limit it to 350ma per light source. I haven't been able to find charlieplexing examples at that current, but I'll keep looking. The store links are very helpful; thank you...

    LED dome

    I'm looking to make something conceptually similar to this: I was wondering if anyone has thoughts regarding: How to implement PWM for ~200 channels. How to buy hundreds of Luxeon / Cree emitters for relatively cheaply.. Thanks for reading!
