Workshop Arduino Shields II — Photo Report

 

Laser Etching a PCB with a RepRap by Leonardo

Leo­nardo has been wor­king on a laser-head RepRap for some time. His latest expe­ri­ment was etching a PCB with it. Above is the video of the first tests, but go on over to his blog to check out all the details.

Arduino Hack Day

I want to join !

a glove that lights up when you shake hands

light up glove

This mit­ten lights up when its wea­rer sha­kes hands with some­one. It has two expo­sed soft con­tacts around the thumb and across the palm which, when brid­ged by bare skin, turn on the LED embed­ded on the flower. The mit­ten itself was cre­a­ted by fashion desig­ner Isa­bel Tomás, and we then sewed a sim­ple touch switch cir­cuit onto it using con­duc­tive fabric and thread. It also works with high fives and hol­ding hands :)

high five and holding hands

Isa­bel and I desig­ned this as a soft cir­cuits exer­cise for some upco­ming mate­ri­als workshops. You can find all the ins­truc­ti­ons and ima­ges we pre­pa­red for this pur­pose @ openMaterials:

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 :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

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.

Control your motors with L293D and Arduino

I rea­li­zed there was some lack of infor­ma­tion regar­ding the use of this chip with Arduino, so I made this Ins­truc­ta­ble. Hope you find it usefull ;)
