Playable Papercraft Piano Box

Our foun­der Cata­rina Mota @ NYC Resistor

From NYC Resis­tor website

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!

Olá tudo bem?

Era só para dizer que gos­tei muito do workshop.
Está aqui uma ani­ma­ção que rea­li­zei em casa com os conhe­ci­men­tos adqui­rido no teu workshop.



Podes ver tam­bém o meu web­site que tem alguns pro­je­tos rea­li­za­dos no Blender.

Gos­tei muito e espero que haja mais workshops do Blen­der que achei espetacular.

Um abraço:

Friendly robots!

A swarm of robot’s inva­ded yes­ter­day AltLab mee­tup… swarm… meh… should I say… 3? Well… 3 it’s gre­a­ter than 2, so… a small swarm of robots inva­ded AltLab!
They were brought by André Almeida, from Artica.Two of them were Gui­bots and the big­ger one is a Maga­bot.
The Gui­bot is Far­rusco is a small robot based on the Arduino plat­form, in this case it’s using a Moto­ruino wich is an Arduino clone with a cou­ple of enhan­ce­ments – dc motor dual con­trol­ler, servo and sen­sor plugs, pos­si­bi­lity to select 5v or exter­nal power source for motors and PWM pins.
With Far­rusco you will be able to make it avoid obs­ta­cles, fol­low walls, enter in free space mode, and in the future more add-ons will be avai­la­ble, just to name a few: line fol­lower, spe­a­kers and light sen­sors, RGB leds, and so on.
Maga­bot is an Arduino based, open source robo­tics plat­form desig­ned to give mobi­lity to any por­ta­ble com­pu­ter and in this case Skype was used to con­trol it… video con­fe­rence with the abi­lity to stroll around a remote room/office.

Pedra d’Água

CONCEPT:

This project’s desig­na­tion intends to pro­ceed to a new over­view of the human con­di­tion.
We must think of a box that is direc­ted to the inside, to the place where we find our mea­ning and where, the­re­fore, we part in search of our sig­ni­fi­cance.
I want to relive this awa­re­ness because it implies a demand and this demand will take us, no doubt, to some kind of fin­ding.
We can des­cribe “Pedra d’ Água” as a Tech­no­logy and Digi­tal Art Tem­ple, that tries to raise the need of one for another and the ritual way we cho­ose to cele­brate the emp­ti­ness left in us when some­one lea­ves.
I won­der if in a near future, this kind of tech­no­lo­gi­cal chi­mera will be the only way to ensure the exten­sion of our dise­a­sed and lost into the living world.
Also, I ask myself if the machine beco­mes equal to the human cre­a­tor, like a post-maker without the bur­den of a body or if the cre­a­tor beco­mes domi­na­ted by tech­no­logy. We must stop and medi­tate over the pos­si­bi­lity that this way will lead us to the over­powe­ring of machine over human, taking us further into ali­e­na­tion.
Nowa­days it’s been noted a high num­ber of vari­ous mani­fes­ta­ti­ons by web users meant to be some kind of memory or tri­bute to the dise­a­sed loved ones.
Today, fri­ends and family keep web­si­tes upda­ted, as if they refuse to accept the impo­sed absence. They keep their rou­ti­nes, exten­ding an emo­ti­o­nal con­nec­tion simi­lar to the one that was expe­ri­en­ced with the loved one.
“Pedra d´Agua” will be like a sanc­tu­ary that will regis­ter mani­fes­ta­ti­ons from web users: when some­one wri­tes or upda­tes one of this “tri­bute” sites, Pedra d´Água will light up, rele­a­sing a sound. When we don´t find find upda­ted infor­ma­tion, Pedra d´Água” will cry.
I wish to cre­ate a arti­fact that claims our soci­ety as one of living but, also, as one of dead and that will allow the per­pe­tu­a­tion of the indi­vi­dual and col­lec­tive memory accor­ding to a new way: the web.

 

Doodling in 3D

Don’t worry, he’s mos­tly harm­less!
Basí­lio, a good­fella, a Lobs­ter, a good fri­end and a Goo­gle Sket­chUp ninja!
Well, yes­ter­day was AltLab mee­tup day, and the plan was: make a 3D model of an X axis car­ri­age for a mini-mendel.
It was a suc­cess! After a few hours using Goo­gle Sket­chUp, we’ve mana­ged to cre­ate a darn good loo­king car­ri­age.
The next step will be print it and assem­ble it.
