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”

by Njay in

(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/ audienciazero.org
Lotação máx­ima de 10 par­tic­i­pantes
Sábado 13 de Março de 2010
Alt­Lab em Cacil­has
14h00m
5€

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/ audienciazero.org
Max­i­mum of 10 par­tic­i­pants

PAPERduino’s design

5
4 years ago
by guibot in

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 :D

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

Down­load PDF

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

Instruc­tions:
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
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.

Paper and cardboard circuits

A cou­ple of years ago i found out on the “inter­nets” that you don’t really need a pro­to­board or a cir­cuit board to make your cir­cuits come to life, the idea was to fold a piece of paper with the cir­cuit design in it (com­po­nent side and cir­cuit dia­gram side) and then insert­ing a piece of card­board in the middle.

The main idea was the eco, recy­cled “thingy” since cir­cuit boards are not so eco friendly and take a bunch of time to get recy­cled by our mother earth, also the eco­nomic side (paper and card­board are almost free), instead cir­cuit board­ing takes a long time and it’s haz­ardous for the environment.

So here’s what i do :

1– print the schematic you want (be sure to include on the sheet of paper both sides of the schematic (com­po­nent side and schematic)

2-fold it (the idea is to fold where the com­po­nent side meets the schematic)

3-cut a piece of card­board and insert it in the mid­dle of the sheet of paper

4-glue both sides on to the card­board (now you must have a beau­ti­full cir­cuit board made of cardboard)

5-with a nee­dle pierce (com­po­nent side) all drilling holes into schematic side

6-insert the com­po­nents (resis­tors, ic, capac­i­ta­tor etc..)

7-turn it back (schematic side) and start to sol­der (be sure to folow the traces on the paper), the best way to do this is to sim­ply bend the leads of the com­po­nents and sol­der them together, if you have a large area were the lead is not long enough just use a wire or some­thing similar.

8-have fun
