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 […]
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.
I spent some time earlier in the week getting the bandsaw at Hackspace Manchester working, so now its cutting again! The main problem with the bandsaw is cutting straight, as it was an ebay purchase it diddnt come with a fence, so there was nothing to run the cut material against. This model of bandsaw hasnt […]
Ok, bit of explanation first. We have an iMac set up as a ‘democratic jukebox’ at HAC:Manchester. The idea being that anyone can put music on it, and it plays the entire library on shuffle during our hack sessions for a bit of background music. The problem is, of course, some people have an… odd […]
Found these the other day, may be handy for anyone doing something they want GPS assisted. I’m considering the em-411 for the quadcopter’s GPS assist (as its the only self contained unit).
