Bluetooth 4.0 (BLE) - 04: Etching a PCB at Home

After a whole day of editing you can finally enjoy my PCB etching tutorial. Etching at home isn't really very difficult. You can even get the chemicals from an online store, since they aren't very dangerous. You might have to give the shop a note, that you are not using it to build a bomb (at least in Germany). Give it thumbs up if you liked it and subscribe if you like more of this.

P.S.: If you don't know what I meant by the guy in Robocop just search the interwebs for "robocop acid bath" (caution: I had nightmares as a child from this scene) And also if you don't know Breaking Bad... then... then... seriously?! I wish I could delete my memory and watch this awesome series all over again. ... https://www.youtube.com/watch?v=G7xVEpTBbkU
