Where are my LEDs?

I haven’t done any work on the old Light Show for a while because I’ve been waiting for some WS2812B LED modules from an eBay seller in China. It’s been so long that I’m thinking of just making my own WS2812B modules. I was hesitant about doing that in the first place since I’ve never used these LEDs before, but, besides the cost, there’s not many reasons why I shouldn’t try. I can get the WS2812B LEDs and capacitors from a local (well, within the province) supplier and the PCBs take about two weeks to manufacture and get here if I pay for fast shipping…

Thanks to the popularity of these LEDs, it’s not hard to find the resources I need. I’d like to try other PCB layouts in addition to the simple single LED board. I think this could turn out to be a really fun project! I will have more to share on this when I get a little more of it completed.

While we’re still on the topic of the Light Show, a few other parts came in for some upgrades. I purchased 5 more pumps which look better than the original pumps. My intention was to have them as spares to replace any of the pumps that don’t perform well, but now I’m considering expanding the number of fountains. The main challenge with that is finding or building a larger pool since the current container is too small for that. I also got some new mosfets in so I can redo the circuit for the pumps. I’ll have to decide how many pumps I’m going to be working with before I get to that…

As a side note, a new PCB design of mine should be here by the end of the week so stay tuned for that as well!
