I have quite a few already but more will be added.
Current projects into LED/RGB Christmas light panel. Current panel is 96"x48" with 1152 LEDs. I'm considering rebuilding it to be a bit smaller over all but with higher resolution. This looks good right now if you are far enough away (50+ feet). I've thought about putting it on the roof and sending messages to Delta flights as they head north over head.. ;)
I've pretty much decided to buy a 3D printer (finally). The MakerGear M2 seems to be a very good one with excellent repeatability and durability. I'm thinking this might be a good "diversion" while I'm in treatment. Where was this back when I owned a hobby shop ! (And David Burnell was alive. He would have loved it. Miss you Dave...)
