Workshops at BetaLab

In the next weeks we’ll be giv­ing two work­shops at Beta­Lab, a co-work­ing space orga­nized by beta­haus| within the Chi­ado-After-Work pro­gram.

Here’s all the infor­ma­tion and work­shops’ sched­ule (in Por­tuguese):

Work­shop DIY Kinetic Solar­Bots — Con­strua o seu próprio robot cinético solar.

Neste work­shop os par­tic­i­pantes vão con­struir um pequeno robot cinético através da mon­tagem de um cir­cuito solar com um pequeno motor e do design/modelagem do corpo do robot com Shmel­zolan (plás­tico uti­lizado em arte­sanato).

Datas : 12 de Maio / 19 de Maio / 26 de Maio

Horário : 17h — 21h

Preço : 25 Euros/Pessoa

Local : Rua Gar­rett, 70 (Baixa, Lis­boa)

Work­shop Elec­trónica Apren­der a sol­dar

Qual­quer pes­soa é capaz de fazer uma boa sol­dadura, é só uma questão de prática! Neste work­shop apren­demos a sol­dar con­stru­indo cir­cuitos muito diver­tidos como o Pisca-Pisca LED, uPONG (Retro Video GAME), Draw­dio (um lápis/pincel que emite sons enquanto desen­há­mos) entre out­ros.

Datas : 14 de Maio / 21 de Maio / 28 de Maio

Horário : 17h — 21h

Preço : entre 10 — 35  Euros/Pessoa (con­soante o kit selec­cionado para con­struir)

Local : Rua Gar­rett, 70 (Baixa, Lis­boa)

Mini-workshop “Motores de Passo”

(scroll down for Eng­lish)

Vamos pegar aleatóri­a­mente num motor de passo e ten­tar desco­brir que tipo de motor é, desen­har um dia­grama sim­ples do mesmo.
Depois vamos pegar no ferro de sol­dar (não há que ter meeeeeedo :)) e mon­tar um cir­cuito que per­mite con­tro­lar esse motor a par­tir de um Arduino ou qual­quer outra placa baseada num micro­con­tro­lador.
Todo o mate­r­ial é fornecido e fica para os par­tic­i­pantes, sendo ape­nas necessário trazer ferro de sol­dar e mul­ti­metro (ou esperar que alguma alma cari­dosa vos empreste).

O número de par­tic­i­pantes é lim­i­tado pelo que, se dis­serem que vêm, con­ta­mos MEEESMO con­vosco 😉

Para inscrições e pedi­dos de infor­mação: work­shops /arroba/
Lotação máx­ima de 10 par­tic­i­pantes
Sábado 13 de Março de 2010
Alt­Lab em Cacil­has

Let’s each of us pick up a ran­dom step­per and try to find out what kind of step­per it is, draw a sim­ple dia­gram.
Then pick up the sol­der­ing iron (have noooooo fear :)) and assem­ble a cir­cuit to con­trol that motor from an Arduino or any other micro­con­troller-based board.
All mate­ri­als are sup­plied to the par­tic­i­pants and every­one gets to keep them; you’re just required to bring your own sol­der­ing iron and mul­ti­me­ter (or wait a ran­dom amount of time to bor­row some­one else’s).

The num­ber of par­tic­i­pa­tions is lim­ited, there­fore, if you tell us you’ll come, we’ll REEEALLY be wait­ing for you 😉

For reg­is­tra­tion and infor­ma­tion requests: work­shops /at/
Max­i­mum of 10 par­tic­i­pants

First Soft Circuits Open Lab

soft circuits open lab

This Sun­day we’re hold­ing our first Soft Cir­cuits Open Lab at the School of Fine Arts in Lis­bon (FBAUL — Fac­ul­dade de Belas Artes de Lis­boa). There is no pre­de­fined struc­ture for the event. We will meet for the course of one day with the pur­poses of shar­ing knowl­edge, exper­i­ment­ing freely, advanc­ing on-going projects, and just hav­ing fun work­ing together. Some of the peo­ple attend­ing will be spe­cial­ists in elec­tron­ics and oth­ers in tex­tiles. Bar­camp style impromptu pre­sen­ta­tions are very wel­come.

Alt­lab will pro­vide some basic tools such as pli­ers, scis­sors, sol­der­ing irons, iron­ing board, etc. But par­tic­i­pants must bring all the mate­ri­als and addi­tional equip­ment nec­es­sary for their own projects/experiments (includ­ing lap­tops). Here are some sug­ges­tions: any kind of fab­ric, nee­dles and thread, yarn, t-shirts, con­duc­tive and/or resis­tive fab­ric, con­duc­tive thread, con­duc­tive and/or resis­tive yarn, knit­ting and/or cro­chet nee­dles, LEDs, coin cell bat­ter­ies, bat­tery hold­ers, EL wire, strands of fiber optics, cop­per foil, cop­per adhe­sive track, alu­minum foil, resis­tive foam, reg­u­lar foam, arduinos (lily­pad or any other kind). If you’ve never worked with any of these mate­ri­als and don’t have them handy, come any­way, you can help some­one else with their project and learn along the way.

For more infor­ma­tion on soft cir­cuits tech­niques and mate­ri­als, check out the Soft Cir­cuits Resources sec­tion on the open­Ma­te­ri­als wiki.

This open lab will take place on Feb­ru­ary 21st, from 10:30 to 18:30, at the School of Fine Arts in Lis­bon, room 307, 1st floor (since our own space is still under con­struc­tion). All are wel­come, there is no fee nor reg­is­tra­tion, but please do let me know if you are plan­ning on com­ing: catarinamota(at)

PAPERduino’s design

This is a fully func­tional ver­sion of the Arduino. We elim­i­nated the PCB and use paper and card­board as sup­port and the result is.. the PAPER­duino 😀

This is the the first ver­sion of the lay­out design, next we will try more designs, and other mate­ri­als. You just need to print the top and the bot­tom lay­outs, and glue them to any kind of sup­port you want. We hope that you start mak­ing your own boards. If you do, please share your pho­tos with us, we would love to see them 😉

There is no USB direct con­nec­tion, so to pro­gram the paper­duino you will need some kind of FTDI cable or adapter. One of this prod­ucts will be fine:
FTDI cable from Adafruit Indus­tries
FTDI adapter from Spark­fun
