Boolier

thingiverse

(We say boulier for abacus, thus that pun with George Bool, father of the famous boolean algebra) It's an object to teach computer science to kids, without computers :) e.g.: JPEG compression and other binary related things. You can see how the tokens switches on this short video : http://flic.kr/p/auGs4d The original idea was brought up by friends at our Makerspace for the Science Fair. And there will be others things to come in this "Computer Science In Real Life" project :) http://wiki.nybi.cc/index.php/CSIRL Instructions DownloadArrangeCut (or print a little version) The models were finally made in 3mm acrylic for the base/sides/tokens (less friction than wood/wood) and 5mm for the long support parts. The "full3mm" use two support of 3mm instead of one of 5mm. The last file "renfort" is easy to cut in leftover sheet Glue the long parts with the base (we're thinking of a second version that will be assembled without glue). That board may also serve to play/teach things we didn't thought about, feel free to remix :)
