The original micronoise-in-a-tupperware we built at various festivals and workshops.
You can buy the parts from our shop.
NAND Schmitt Trigger Oscillator
The NAND gate is a logical circuit and plays a very important role in all digital technologies. Its purpose is to compare ones and zeros and a resulting output!
The abuse of the NAND gate by a feeding back an oscillating R-C circuit makes the Schmitt Trigger to oscillate at an audible frequency. A sound is generated!
Assembly plan
Ok, let’s try this and go for some soldering action…
Tips: melt some tin onto the copper pads before soldering. Do one thing at a time.
-> IC-chip, the groove on the chip has to point to the right
-> Battery-clip, red is +, black GND (outside area)
-> Attention C1 is polarized, + = top, – = outside area
-> LED is also polarized, long leg to the left
-> mini-jack, inner ring is GND (outside area)
Now mount everything into a nice little box so you can make real music with it. Using the jack output you can connect it to an amplifier and listen to the micro noise for real!
Electronic schematic
SGMK’s micro_noise uses two NAND gates, where the first one (LFO) turns on and off the second one, which generates the tone modulated by the photosensor.
POT1 is reducing the current to the chip in a non-conformal way, which makes it scream and noise…

aarg, i like micro_noise so much. pure crazyness. made a version2… video.google.com
thank you mechatronicart.
awesome!!!!!!!!!!
i m loving it.
Shoot! Wanted to upload my video; didn’t work, will try again at a later stage!
das isch wohl au meeeiiigiii

Hallo zusammen.
habe am samstag bei euch gelötet, war grossartig danke, aber jetzt funktioniert mein lärmmacher nicht mehr und ich find nicht heraus warum… und das macht mich traurig… wo krieg ich hilfe?????

Did this micronoise kit guided with the expertise on the subject of a 3 year old boy, he was the one choosing the package (see pic):

only problem we have is that the sound output (headphone jack) doesnt seem to be affected by the photoresistor, that does its job well on the speaker (piezo)
any hints appreciated, and yes, tx for such a nice kit!

Läuft der Micro Noise wieder? Ansonsten meld Dich bei uns per Mail.
Hey hello, here xname, we met at piksel this year. I attended part of the workshop and you gave me this kit at the end to build at home, but few parts are missing: the chip, plus jack and speakers.

Can you send me the missing parts, please?

I am interested in buying a theremin kit too.
Best wishes, xname
Hello, great noise gen, we got the first prize at the Italian competition for electronic drums hacking it with lights!!
