Here’s a handy tip from the forum for those etching PBC’s at home: forum post
…about 4 years ago, I saw that someone said that you could protect an etched copper clad PCB with polyurethane once you were done soldering. So as a test, I grabbed a scrap of PCB and scrubbed it up till the copper was shinny. I then sprayed 1/2 the board with polyurethane, and left the other half bare. I put it on a shelf, and it’s stayed there ever since. That was four years ago.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
