The piano box is a (somewhat polypho­nic) paper toy synthe­si­zer with 12 keys, each trig­ge­ring a tone and an LED. The keys are a set of capa­ci­tive sen­sors, made of cop­per tape, con­trol­led by an Arduino Mega run­ning the Cap­Sense and Tone libra­ries. The code for this pro­ject, writ­ten by Will Byrd and Cata­rina Mota, can be down­lo­a­dedhere. Ple­ase note that the cur­rent ver­sion of the Tone library has some pro­blems on Arduino 1.0. so it’s best to use ver­sion 23 or ear­lier.

The libra­ries used are avai­la­ble here:

So full of win!

So it was, yes­ter­day AltLab mee­tup was full of win.
It star­ted with some­one showing off his pro­ject, Laser Tag… no, no lase­rish paint­bal­lish kind of laser tag, it was more graf­fiti tag­ging, but using a laser poin­ter, a video pro­jec­tor, a camera and a kind off nifty soft­ware 🙂
Everyone played with it, and hea­ded back inside, it was a kind of chilly in the back alley.Next, João Neves and me went on a date with Vio­leta… It was a kind of thre­e­some, but Vio­leta is AltLab Cup­cake 3D printer!I tried prin­ting a part from a Wal­lace, bat as usual, Vio­leta didn’t finished the print, and I was using my com­pu­ter, so the plot thic­kens! 🙁


The pro­blem is in the prin­ter, now we’re cer­tain of this! We sca­ven­ged AltLab junk… err… the nice and very orga­ni­zed warehouse for ATX PSU, and tried a few, but that didn’t, so we plug­ged the ori­gi­nal one back, and it wor­ked! Vio­leta is prin­ting again, at least two parts for Franky (a mini-men­del) without a hitch, the future will tell us.


And the pièce de résis­tance was the first test of a ste­reo litho­graphy prin­ter… “what?!!?” it’s a 3D prin­ter using photo sen­si­ble resin as a medium, very impres­sive piece of tech­no­logy. They made some expo­sure tests to unders­tand how long they need to expose the resin for a per­fect cure, it’s around 15 seconds and they-re ready for the next layer 🙂 A full of win day!
