Soldering is Easy workshop report

Ter­rific night yes­ter­day @ alt­lab!
The work­shop started with an intro to elec­tron­ics leav­ing the atten­dees anx­ious to get down to sol­der­ing.
Despite that, every­one was focus­ing their atten­tion on what was being said.
Half an hour later the sol­der­ing irons were plugged in and the fun started.
Soldering is Easy!
Hands-on and hav­ing fun!

Here is the final result, every­one leaves with their own blink­ing gad­get.

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 😉

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

Com­po­nents list:
1 x 7805 Volt­age reg­u­la­tor
2 x LEDs (dif­fer­ent col­ors)
2 x 560 Ohm resis­tors (between 220oHm and 1K)
1 x 10k Ohm resis­tor
2 x 100 uF capac­i­tors
1x 16 MHz clock crys­tal
2 x 22 pF capac­i­tors
1 x 0.01 uF capac­i­tor
1 x but­ton
1 x Atmel ATMega168
1 x socket 28 pin
Female and Male head­ers

Use a nee­dle to punc­ture the holes for your com­po­nents.

Don’t rush, place one com­po­nent after another and do all the sol­der work care­fully.

Fol­low the con­nec­tion lines.

And this should be the final look of your paper­duino con­nec­tions.

openMaterials :: research project

My dear friend Kisty Boyle and I recently launched open­Ma­te­ri­als — a col­lab­o­ra­tive research project ded­i­cated to open inves­ti­ga­tion and exper­i­men­ta­tion with DIY pro­duc­tion meth­ods and uses of mate­ri­als. In the spirit of the open source soft­ware and hard­ware move­ments, we hope to pro­mote mate­ri­als to be researched and devel­oped in a pub­lic, col­lab­o­ra­tive man­ner. We see mate­ri­als as an open resource, and wish to estab­lish an open process for explor­ing and shar­ing knowl­edge, tech­niques and appli­ca­tions related to mate­ri­als sci­ence.

I’ll be con­duct­ing most of my hands-on research right here at Alt­Lab. We’d love for you to be involved if you are work­ing in these areas or inter­ested in learn­ing more about smart mate­ri­als.
