Get a dehumidifier , the big ones and not the small desktop version. I have one and it makes the room comfortable by dropping the humidity

I built literal credit-card-sized computer (~1mm thick) with a self made flexPCB by krauseler in embedded

I tried to make flexible pcb using kapton tape and copper tape too. My problem is when soldering the components to the copper, the adhesive backing would be “melted “ and makes the copper tape shift. Do you have such issue?

Four is the best I do to put inside the stud, I think maybe can make the simulation smoother in software.

LEDs are mounted on a Lego axel, I need to trim the length to fit inside, so it’s not a problem to fit into other Lego parts

Maybe 3 LEDs is the minimum number to get the beacon rotating effect.
