As part of the Hackspace Manchester door control system, we have a raspberry pi running a little script that checks scanned cards against a database of members and opens the door if the card is known. This has been humming along happily for around 3 years now, until recently it stopped updating card IDs when […]
I’m a big fan of the SmoothieWare project for driving 3D printers, CNC machines and Laser Cutters. The code is clean, efficient, and the software actually designed in a modular and sensible fashion. Compared to most 3d printer firmwares, which have accrued layers of cruft, its very readable and usable. The only real issue is […]
We like to do occasional workshops at the Hackspace, so when MadLab asked us to make something ‘bug themed’ for a workshop, we jumped on it. The first thought we had was to make up some bug-shaped PCBs with a circuit to flash LEDs, and run a soldering workshop. When we found out the workshop was a […]
I’m a big fan of XBMC, and have an Ouya running XBMC set up in my lounge, streaming from my NAS. I normally use XBMC remote on my phone for controlling it, but this gets annoying when the phone is on charge, or I’m using it for something else. I noticed that the majority of […]
Over the weekend I ordered the mainboard for the new robot. It contains an arduino, battery voltage monitoring, battery regulation and a pair of motor driver chips. It is designed to sit on top of a hardcase 5Ah LIPO, with short leads going into the battery power output.
Last night I retrieved the first chassis printout and did a test assembly with the parts that have arrived. It looks good! The axle distance is perfect, the chunks I carved out for the pi are all the right sizes, and it looks bitchin. The only negative was that the mount for the raspberry pi […]
Before leaving the hackspace on saturday, I set the wheels and motor mounts for my robot printing, as I figured these parts probably wont change while I finish the rest of the design. Tonight, I cleaned up the printed parts, and did a test assembly of the track sets: They looked about right, so I […]
Here is a teaser shot for my new rover robot, based around a raspberry pi and a massive lithium battery. Fairly heavily inspired by Wlll’s ball collecting robot.
