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!

One of the more ludicrous (but delightful) boards I was given at #Supercon was this one - the CapKey. It's a capacitive-touch keyboard the size of a keycap.
Would tag the maker, but can't seem to find him!

In #Florida, it's illegal to not #vaccinate your dog, cat, and/or ferret. It's considered by law to be animal cruelty.
Not vaccinating your children, however, is "doing your own research".

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.
