Finally got some denser RGB LED strips in, and while I'm not sure they're brighter, they're more fun.
Still more experimenting to do!

That's definitely going to need to be brighter - it's also hard to take a video of!

A little #RaspberryPiPico project with a DAC for sound effects, some lights, and a PIR for motion sensing.
Should be "fun" for the trick-or-treaters on #halloween!

This is mostly a thought experiment, and LEDs have long been used as useful indicators in oscillator circuits, but LED noodles can be a useful tool to help "see" what's happening in a circuit.
