food for your stomach

Fee­ding 15 sleep depri­ved hac­kers is not an easy task and during the AZ Resi­dency only 3 peo­ple were brave enough to put their culi­nary talents to the test: Joel, Vitor and Mari­ana. Everyone agreed that their home­made meals were awe­some and no bug reports were filed. Since we beli­eve in sha­ring, here are Joel’s deli­ci­ous open source reci­pes (in french comme il faut):

Salad Dres­sing [ VO ]

4 cuillère à soupe d’huile d’olive
3 cuillère à soupe de vinai­gre bal­sa­mi­que
2 cuillère à café de miel

Goû­ter et ajus­ter : si trop sucré, ajou­ter du vinai­gre / si trop amer, ajou­ter du miel.

makerbot as microscope: what we learned

Joel Belouet has been wor­king on an art piece invol­ving micro­or­ga­nisms and nee­ded a sup­port struc­ture for his micros­cope camera. It turns out the Maker­Bot sit­ting on our table was the solu­tion.

At first Joel atta­ched the camera to the z axis and the slide res­ted on the build plat­form, but it soon became clear that it would be much bet­ter to have the sam­ple remain still and the camera move ins­tead. Inver­ting the posi­ti­ons meant atta­ching the slide to the bot­tom of the z axis plat­form in order to pre­vent the camera lens from bum­ping against it. This setup also allowed him to use the z crank as a focus mecha­nism. Con­ti­nue rea­ding “maker­bot as micros­cope: what we lear­ned”

Thom Yorke 3D Print by Tiago Serra

During our recent 3D Prin­ting Workshop, Tiago Serra from xDA used altlab’s Maker­Bot to print a model of Thom York’s head 🙂

Drum Pads



Four drum pads ready to go.

All made of old mate­rial found in the Alt/Lab ins­tal­la­ti­ons, and a very spe­cial big thankxxx for Mónica who brought the casings (we are going back to that in a moment) for the drum pads.

So the idea was to make drum pads that we could hook up to a sound card(or wha­te­ver) and them make sweet music, this is a very nice com­bi­na­tion between pie­zo­e­lec­tric com­po­nents and a few layers of some absor­bent sound  mate­rial like rub­ber or cork foil (that’s what we use because there was nothing more) and a piece of alu­mi­num foil for a gre­a­ter drum area .

We use an old can (20l) of paint, four pie­zo­e­lec­tric found in elec­tro­nic junk like old modems and old telepho­nes, wire for con­nec­ting the pie­zos, cork foil for insu­la­tion the drum pad area and Mónica sup­ply the casings (square rub­ber cd´s stands), and glue for put­ting everything nice and tight .

First we cut a piece of the can (cir­cu­lar about 10cm radius)and we glued the piezo into it, then we dril­led one hole into the rub­ber casing for the wires to came out, them we cut two square cork foil parts (the first in the bot­tom of the casing and the other for the top) a bit of glue and that’s it drum pads ready to rock.

Now we got some audio coming out of the pads but thats just boring because its always the same and we want to go further like trans­for­ming audio into midi mes­sa­ges, and we found the right tool for it, its cal­led  “KTDrum­Trig­ger” and he trans­forms the audio sig­nal into midi notes, we can use this midi notes inside a sequen­cer pro­gram to con­trol any kind of ins­tru­ment (either VSTI or some other stuff), in our case we use the drum pads to con­trol “Bat­tery” and thats it ins­tant fun.

There are some other links and some other ideas for drum pads. This “one“uses ardu­nio as a source for the imput sig­nal.
