Making, Etching and Printing

We had some awesome meetups the past two weeks. Last week we had our ‘Etch your own Arduino workshop’ which went great. We used the Nanino design for the pcb and they turned out great!

For the toner layout we used the blue Press-n-Peel, its very easy to use and you get great results. For the etching we used ammonium persulfate which is not as nasty as the usual ferric chloride (although you still shouldn’t drink it!), we used gloves when handling the etchant.

DSC_7521We used a regular steam iron for the toner transfer onto the blank pcb. Not sure if the guys would appreciate it if their wives saw that they can actually handle a steam iron …

Last year we started working on our own Cyclone PCB Factory. We were missing some parts back then and the project got shelved for a while. Last night Gerhard and Romeo started working on it again. They managed to get all the mechanical stuff sorted and next week we are hooking up the electronics.

Myself and Sebastian are also currently working on a new monthly project for December which involves the new esp8266 wifi modules and some ws2811 LED’s. Sebastian gave a little demo of the code he has done so far. It’s going to be awesome … more info soon!
