Here we have a fully 3D printed low-cost optical microscope using both a 3D printed chassis and ..yes.. 3D printed illumination and imaging optics too!
There’s a lot more info on their project page https://feministhackerspaces.cargo.site/Clay-PCB-Tutorial but I think it’s important that I provide context re the PCB being part of their disaster survival backpack! That had lots of other things in it too, tho unfortunately I can’t find the video about it now. But yeah, so the PCB was designed for a kinda worst-case scenario.
As regards the urban mining, yeah it wasn’t quite what I expected: “[we bought] silver paint, commercialised by a German company, that is made with waste silver powder collected by jewellery makers. It's like an urban mining technique of silver dust.” I was expecting them to find things and extract silver from them!
We built an Ethical Hardware Kit with a PCB microcontroller made of wild clay retrieved from the forest in Austria and fired on a bonfire...
I just saw this presentation at the Chaos Computer Club conference, for an “Ethical Hardware Kit with a PCB microcontroller made of wild clay retrieved from the forest in Austria and fired on a bonfire. Our conductive tracks use urban-mined silver and all components are re-used from old electronic devices”. It was part of the feminist hardware strand!
