Playable Papercraft Piano Box

Eric Skiff wro­te:

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!
