Hello lines, my name is bob, noisebob, i hack circuits and build them to panels, eurorack style… i thought i’d share my creations here… my goal is to build a complete (hah!) modular synth from 2nd hand and homebrewed modules…

HAMMERTIME


black blob circuit ripped from a toy hammer, three different sounds (none of which actually sound like a hammer), pitch bend. 5HP

ACAB UNIT #1


black blob circuit ripped from a police car toy (hence the name), it’s a siren, with pitch bend. 5HP.

TRIGGER HAPPY


push button trigger unit, nothing spectacular. 20HP.

i keep a blog documenting this whole thing over here, https://noisebob.com

Hi ‘bob’ :slight_smile: these are looking great, I appreciate the lack of attempt to clean up the drilled holes :smiley:

Yeah, we work quick and dirty at NOISEBOB ELECTRONICS HQ…

Next up is a stereo ray gun toy (picked up two identical toys, so I might as well put them both in one unit and call it stereo)…

Maybe…

I’d love to hear this if you have any recordings!

No recordings yet, but I’m having a concert on saturday (that’s why I’m working so manically on this project currently)… will make sure to record it.

Also, I really need to build some kind of mixing circuit… and a power supply.

…and more modules!

so… 3 out of 5 modules died before the gig, (it’s all very experimental ya know)…

i managed to get this out of it:

cool to hear it :slight_smile: nice noises! sounds like fireworks ha

3 out of 5 modules died before the gig

ha that reminds me of the time I took a 32-knob behringer midi controller to a gig to control a gameboy. I had just 3 of the knobs even assigned to anything, which had taken me hours of fiddling with settings and midi messages to get it working with the GB. Took the controlller out to set up and discovered that all 3 of those knobs had completely snapped off in my bag. Was so annoyed I just threw the thing right across the room and never looked at it again :smiley:

This is the “footnome”. It is a hand wired momentary switch and LED’s matrix mounted on a 5mm aluminium faceplate and connected to a 40h logic board.

(The device dates back to the time where grids were also referred to as monomes, hence the name «footnome».)

And this is the story behind it:

In 2010 I had bought two 40h kits, one of which had a faulty logic board and resulted in a row of LEDs not lighting up (and unresponsive button presses, I can’t remember). I swapped shift-register ICs, CPU and examined traces but never found out why it didn’t work properly. After having described the problem to @tehn he was so kind to replace the logic board and so two weeks later I had two fully functional 40h kits (Thank you again!).

Since I still had one not fully functional logic board left over I decided to make use of it. As the fifth row from below was disrupted I decided to make a 4x8 grid to use as a footpedal in conjunction with “Pages” and Ableton Live. At the time this turned out to be very rewarding, as playing bass guitar and pushing buttons simultaneously is beyond my physical capabilities and the visual feedback of clips was very helpful on stage.

this is 2 6 rollz, 1 3 rollz, 1 4 rollz and 3 5 rollz, with an XOR matrix and 3 mono outputs - my first complete build!image0 (1)

Wow this looks intricate, I’m digging it!
Could you explain whats going inside? Essentially, the spring reverb tank is all i can decipher from looking.

This is my new favorite instrument, my first guess, from the look of it, is it’s a flute ?

it’s an open accordion! half of it at least. it belonged to my mother when she was a child :slight_smile: these are the objects that I used to prepare the piano and guitar for, little by little I left the instruments aside and kept only the piezos
and the objects(coolers, bass strings, different metals, springs etc)…one day i decided to put them all together in a kind of box, then came the idea to prepare the accordion + 6 piezos contact microphones >> M.I.Ears. The spring reverbg goes to a moogerfooger rack. it’s an instrument that I’ve been enjoying exploring a lot, I usually play it with volcanic stones and a violin bow, It’s a lot of fun :))

@aaumgn Love the reflection of you taking the photo with your arms above your head. Bit of a trainspotter for this on ebay too.
Looks a very dense applicaion of the piezo intrument thing. Love that it its parts have a biographical relevance for you.

That sounds awesome dude, great work.
Would love to hear how it sounds!

Recently completed a DIY Ondes Martenot-style controller, based on a design by Dana Countryman. In this video, I use it to control pitch on my modular system. I control volume with an Expressive E-Touché.

Are there any demos of this in action?!

I’ve recently built a rollz box and am loving it. Curious as to what the addition of the XOR matrix adds to the functionality? And also what those pots along the top are doing?

yeah i’ll link to the youtube video! unfortunatley the XOR didn’t do as much as i thought it might but i’m trying to come up with some ways around it - maybe buffering the inputs or something or some time of R/2R dac to try to make the pulses more legible?

i actually unboxed this recently because a friend gifted me his first eurorack case so i’m repurposing it to be my new ciat box! its going to be all these rolls, a bunch of gongs, esoterica, and all the stuff in the dogslit - wish me luck :upside_down_face:

the pots at the top were supposed to be some kind of mixer situation which didn’t really work but they wound up functioning as passive attenuators which did have some really cool results! highly recommend throwing a few of those into any rollz build
