Over the last few days there’s been loads of activity at the hackspace, today we’ve had mosfet power controllers, Bristol Braille, bike automatons, CNC spoon milling, PCB design & fab, cardboard surfboards, set design and solar phone chargers! It’s fantastic to see so many varied activities all going on in the space.
I spoke to the guys from The Converging World about their solar phone charger and persuaded them to pose for a photo.
They’re using an old farm’s 120W solar panel to charge a 12V battery (inside the drawers). Then using the classic trick of car mobile phone chargers (the circles in the top drawer) to step down the battery suitable for mobile phone charging. It’s all come together over the last 2 days and they just left the space on their way to the festival. Good luck!
and here’s the current version, before finishing (Sab rather likes the diagonal lines):
The key, he says, was a combination of parameters and tweaking until he got the effect he wanted. Vectric has a free time-limited trial, which was very useful as he could simulate the shape and texture without having to come down to the Hackspace.
At the regular Hackspace open evening on thursday he was discussing with Richard and Anton how to finish the spoons. His original plan was to finish it by hand: Richard’s suggestion was a fine and fast last pass on the router; Anton suggested buffing it with a wheel and Tripoli.
Some of the wood lathe chisels had got blunt so Anton took them home where he has a jig ready to give the chisels the right shape again. We’re currently discussing which grinder to upgrade to, and it seems it might be a good idea to get one with a jig for these tools.
Our latest skill share workshop is using 10 Arduinos and a Raspberry Pi. We bought a brand new bunch of 10 but wanted to make sure they stayed at the hackspace! Joe kindly offered to design a board to hold one alongside a breadboard. We think they came out great! Thanks Joe!
