Wow, I'm still overwhelmed that my R2B4 robot won the runner up prize in the Sixth Sense Design Challenge . I was quickly contacted by danzima to tell me that my prize was being shipped.....and yesterday this box was delivered by UPS. Up until then I had never used a 3D printer let alone owned my own one. About two years ago I started trying to make my own following along the lines of a Prusa i3 but without access to a 3D printer to make the joints I found myself using pieces of metal, wood a ...

During a discussion over a friend's flat car battery they brought out their 'car battery booster' but it soon became apparent to me that that also wasn't working....and so, like most tinkerers, engineers and makers, it ended up on my bench at home.   The unit contained a 12v 13Ah Sealed Lead Acid (SLA) battery, large diameter cables and croc clips for connecting to the discharged car battery, a voltmeter, a light and an external cigarette lighter socket. Charging the booster unit was via ...

Satisfied with progress I ordered some more modules...the aim was to control ...
