Although RepRaps, Makerbots and Lasercutters are more common these days, many groups are still lacking CNC routers/mills to create really solid tools or parts for bigger machines. Maybe some of the solutions presented here will inspire other groups, to build more CNC machines and extend our ability to make stuff on our own and for each other, by sharing pl… text/html 2015-01-27T20:28:53+00:00 Anonymous (anonymous@undisclosed.example.com) https://open-resource.org/mission:resources:picodrill?rev=1422390533&do=diff picoDrill Heavily modded proxxon tool and stand.

Where ever we go or whatever technical problem we might encounter, we can just build the parts we or others need to solve that problem. So, in the end of 2013, we had another look at the 3D printer market and a lot seemed to have happened since the RepMan. Almost all major tinkerer suppliers had some form of 3D printer to offer r… text/html 2016-10-27T22:33:20+00:00 Anonymous (anonymous@undisclosed.example.com) https://open-resource.org/mission:resources:picoreflow?rev=1477607600&do=diff picoReflow More and more semiconductors are produced in packages (the chip's case) which have become impossible to hand solder with a solder iron. The switch from through-hole (THT) to surface mount technology (SMT) has actually made hand soldering much easier (although still many believe the opposite to be true) but now we are faced with BGA and other packaging forms which only have contacts on the bottom of the chip. text/html 2023-04-19T13:26:35+00:00 Anonymous (anonymous@undisclosed.example.com) https://open-resource.org/mission:resources:picouvx?rev=1681910795&do=diff picoUVX The picoUVX is a highly efficient, mobile 10W UV-Exposer unit, based on modern LED technology and a very efficient, yet simple step-up switch mode supply design, with a low conversion loss of about 7% (93% efficiency).
