Workshop Ruído Táctil

0
2 years ago
by mm in
Neste work­shop, com a duração de 2 dias, ire­mos con­struir sin­te­ti­zadores low-tech, reac­tivos ao toque, capazes de pro­duzir uma var­iedade de sons e tex­turas em função da posição, humi­dade e pressão dos dedos que tocarem em pontos-de-contacto destes instrumentos.

As tare­fas nas quais os par­tic­i­pantes vão ser envolvi­dos permitir-lhes-ão familiarizarem-se com os princí­pios bási­cos da elec­trónica, nomeada­mente com­po­nentes, esque­mas elec­tróni­cos e processo de sol­dagem. Não se exige exper­iên­cia prévia como pré-requisito e o work­shop é des­ti­nado a todos os curiosos com mais de 15 anos.

Cada par­tic­i­pante ter­mi­nará o work­shop com um sin­te­ti­zador con­struído por si, que per­mi­tirá acabar com o sossego de co-habitantes, humanos, cani­nos ou felinos.

Pede-se que os par­tic­i­pantes tragam con­sigo objec­tos de madeira, plás­tico ou cartão, que pos­sam ser fura­dos (caixas, tup­per­wares, fras­cos, etc) nos quais pre­tendam alo­jar o seu sintetizador.

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:

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)audienciazero.org

Drum Pads

Hey.

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.

Circuit Bending

Hello “intrenets” people(s)

This post today reflects a lit­tle about  what cir­cuit bend­ing and diy are.

I have many friends and col­leagues  ask­ing me “-So what is cir­cuit bend­ing?”, well here goes the awser and a bit of the his­tory behind cir­cuit bending.

Seems that a guy called Reed Ghaz­ala, was mak­ing exper­i­ments with some syn­the­siz­ers, try­ing to get some more sounds out of the elec­tronic instru­ments, so he decided to open one and poke the guts of the beast .

He soon  finds out that the core of an elec­tronic instru­ment its a lot of fun and this could be excit­ing discover.

Now…have you ever heard of the Savant syn­drome ?  a per­son who as Savant Syn­drome have the abil­ity of mix­ing emo­tions, like see­ing num­bers in a wide vari­ety of col­ors or the alpha­bet in shapes and forms, the cause of this, its sim­ply the brain and some short fuses in some areas, and this its exactly what Cir­cuit bend­ing is.

So, when Reed decided to explore the pos­si­bil­ity of the short cir­cuit he open a big door for exper­i­men­tal music and a new form of see­ing elec­tronic devices, the idea its sim­ply bril­liant, lets open some toys, synths, ped­als (what­ever) and lets start to take some really cool sounds out of it, and the bril­liant part is : you don’t need to know about elec­tron­ics or be a geek who spent all day in the garage (myself included), because cir­cuit bend­ing its like a a brain in short fuse.

What you need to cir­cuit bend­ing some stuff ?  This is another ques­tion and an impor­tant one. Hummm lets see:

First, you will need some kind of device that pro­duces sound, like a toy, a dis­tor­tion pedal, an old synth just to name a few.

Sec­ond, this is the impor­tant part DON’T USE ANYTHING THAT CONNECTS DIRECTLY TO THE AC/DC POWER, this means DEATH, instead use bat­ter­ies, all kinds of bat­ter­ies and even trans­form­ers as long you don’t touch that evil 220 V you are in business .

Third, open your device and choose your method of oper­a­tion, this could be done in a vari­ety of ways, you could use your fin­gers with a lit­tle of saliva (ughhh), or two screw dri­vers con­nected by an alli­ga­tor clip.

Four, explore and see if the device reacts to your touch pok­ing some cir­cuits, i often get some great results pok­ing the chips legs and con­nect­ing them together, find­ing the cool points its fun so don’t give up if you don’t find some­thing in the first 5 minutes.

Five, ohh the “intrenets” yes there’s a lot in here just search a bit and you will find your­self in a brand new world, of course the cir­cuit bend­ing com­mu­nity its open minded and friendly, so don’t be shy and ask ques­tions (most of us don’t know what are doing so join the club).

Now you know were Beck, Madonna, Mike Pat­ton and many oth­ers are get­ting they inspi­ra­tion (yeah that’s right Madonna), the musi­cal pos­si­bil­ity are immense, just think  is you, who  are dis­cov­er­ing your own sounds and mak­ing it at the same time (not like a patch in a syn­the­sizer ) some­thing really new and fresh made entirely  by you.

So,  what is Cir­cuit Bending  ?
