Some doings, plans, and developments

The board of Umeå Hackerspace actually performed its function (to the surprise of many),  and held a meeting, laid some plans, and actually did something vaguely related to same.

Specifically, there is now a way to give us money (yay!), namely through Bankgiro 742-4690, meaning that we will soon begin collecting membership fees, and thus have some money to spend on our projects! See the organisation page for details.

Further, there is going to be a small party at the space for the release of Ubuntu 11.04 Natty Narwhal on the evening of the 28th of April. Bring some Ubuntu cola and come eat CAKE, woo!

Plans are proceeding on a bunch of RFID related projects, both in relation to Länstrafiken and to Bostaden. It is quite remarkable how an at least somewhat secure method (regular metal keys) is being supplanted by, in effect, a proven-to-be insecure method (RFID tags) for various reasons. Even more remarkable is that this is said to be done for security reasons. Oh well, money talks, I suppose, as well as shiny high tech sales people.

OpenLase and first Mifare steps

Last night we had a great hacking evening with lasers and security-related wireless transmissions. What more can one ask for?

OpenLase is a sort-of framework with several stand-alone tools which are combined to produce real-time laser graphics with hobbyist-grade components. One of Grill-bit’s hackers hast started fiddling with this, getting Jack to run and connecting the output to his two galvos which twist mirrors to create a laser show.

This is supposed to be a Pong playing field. Due to bugginess we'll avoid posting a video. We'll get back to you when it works as it should :)

So far it’s a bit buggy, mostly because of certain hardware making it impossible to show as many points per second as one could wish for. Nevertheless it’s a cool proof of concept and definitely in the cost-range of any dedicated hobbyist! Real-time laser graphics is definitely something fun we encourage more people to play with!

The actual hardware in use. Two galvos, a soundcard, a board with op-amps etc.

Also we’ve got an RFID reader now for Mifare tags etc. that may come in handy for examining bus cards and entrance passes! Progress is soon to be made.
