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.

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!

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.
