So the hackerspace will imminently have a number of Realtek-based SDRs as demonstrated last meeting. An SDR, or Software-Defined Radio is a very flexible device, that performs the equivalent of a “raw recording” of a portion of the RF spectrum and then the raw samples can be processed in any way you like on your computer.
Monday was a good day for hacking; we had an impromptu Minimus workshop. This was surprisingly successful, attendees were able to get their boards programming in Windows or Linux as to their preference, and then start diving into code.
The devices aren’t as friendly as the Arduino boards, and the example source code will compile but not always run without extensive tweaking, but by the end of the session, in addition to a medley of flashing lights, we also had a one button keyboard and a virtual serial port that reported its button state.
Due to demand we will run another of these in April (2nd or 16th, TBC) and again will have Minimus boards available for use on the day or purchase. There’s no fixed cost for the workshop, but donations are appreciated. If you have a Minimus board or are interested in a step on from Arduinos, why not come past?
As a reminder to Northackton members who are also NSME members, their auction is on the 13th of March.
On Monday we visited Martin’s laser cutter, as once he installed it at his house with a water tank for cooling, it’s not particularly mobile. He showed us some of the many things he’s made for his blog, and his lightbox for photographing them.
This post is unfortunately almost two weeks late, but last Monday, Pat gave a chainmail workshop, similar to Martin’s at Nottinghack. This covered the easier European and Japanese styles and also how to make rings from fencing wire or similar. Many scraps of chainmail were produced, but nothing to rival Pat’s half-finished chainmail shirt!
Nick continued to resuscitate aging hardware in Linux and we discussed methods of supplying Internet to the NSME clubhouse. Via a landline this would be expensive, wireless access of the nearby BT Openzone hotspot, or 3G personal hotspot appear to be the more affordable ways forward…
Next date for the space: Monday 17th October.
