Paper Circuit PCBs?

Author Paper Circuit PCBs?

I just built a Grassic Organ on paper and it doesn't work, I figured it wouldn't because my free hand skills aren't great.

I love the sound of this circuit though thanks to smog filter on youtube for showcasing almost all of the paper circuits! (video below)

Anyway I would love to build multiple grassic organs and eventually the Rollz-5 (does anyone know if I can still get a meng qi board??) and Would be great to have actual PCBs to have a better shot at them working.

Has anyone made PCBs? Or knows where to purchase them? Maybe a limited run of them would be in order...

I messaged meng qi a while ago through etsy, he said he was working on a new rollz 5 pcb. I've seen one pop up on eBay for $100, which was $50 more than I wanted to spend.

I built several rolls, an ultrasound, and most of a gong. The rollz were very easy, but I found soldering to the chips on the other circs extremely annoying.

I too am interested in any paper circ pcbs.

I just Messaged Meng qi through etsy as well.

"Hi, Rollz-5 pcb is in production right now and Grassi is in stock. So both would appear in the shop soon!"

so sweet!! screaming goo yo screaming goo yo screaming goo yo

EDIT: on further inspection the grassi pcb is most likely the 'Old Mr. Grassi' paper circuit, not the grassic organ I was looking for...

Paper circuit PCBs go for sale on the 'Ciat Lonbarde Addicts' facebook group too. Gerassic organ, Esoterica Spikering, Old Mr Grassi etc

News like this makes me regret my Facebook abstinence

I'm not on facebook, but I will surely log onto a friends account to check it out hihi

I was shocked for your design, I did not weld on paper or connected to the circuit.

This site has pcb manufacturers in all regions, but I have not used it.
After a friend recommended I used the wellpcb, is a pcb prototype and assembly of the manufacturers. I ordered a small batch of pcb board, the price in a reasonable range, the quality is fine, I weld by myself, did not use the assembly service.

I built a Lil Sidnrecently, using a PCB from Dennis (Bomono on Instagram m). Works likes a dream.

I've been having problems with building a lil sidrassi myself. I etched some PCBs using the paper circuits for a toner transfer but I used a different FET and op amp and i think thats my problem. I also used banana jacks instead of brass pegs. I get sound from some of the outputs but its not was I was expecting. Apprehensive about ordering the right parts from mouser because I ordered from them last week and they're still not here even though I only live an hour away....

For PCB prototype manufacturing and assembly, you can try OurPCB

Yes I have - I wanted to start doing the paper circuits, but not on paper, as its looks a bit too fiddly. I much prefer a PCB and something more reliable. So i got some paper circuits PCB’s made, as an experiment, and just to see if it was possible to do and for my own personal use/interest. I chose ones that weren’t currently available. I made Rollz 3,4,5,6, Avdogs, Gongues, Deerhorns, 5 star, ultrasound. All the Conrad papers. Dogvoice, Swoop, Rando, Preamp, Swoop spokes, Esoterica Chainlock, 5 Star and Phosphate of Aluminium Crystal Simulation. anti rando, antiswoop, antipreamp, Deerhorn Berlin, Deerhorn Moon, Deerhorn Prov.














And this is how I did it

download Peter B's PCBs:
http://www.ciat-lonbarde.net/TIMARACURRICULUM/TIMARATERIALS/cirques/pa pers.zip
You will need to rename these files to .osm files for it to read.
Download this software https://www.osmondpcb.com/download.html
Open any of the .osm files that you have in that program.
After opening you need to export to Gerber file.
File -> Export -> Gerber Files
Press OK.
You get a message that says "Not all paths connected" just ignore and Press OK again.
Goto the folder were it's exported (it will be in the same directory as your .osm files
and in a folder for example "GerberFiles_conrad_preamp"
Inside it are lots of little Gerber docs.
Zip that folder up.
That zip is what you send to the pcb manufacturer.
I used www.JLCPCB.com
But you can use any.
Theres a review site at www.pcbshopper.com to choose which manufacturer you want to use
That's it. Usually there's a minimum order of 5 PCB’s.

These look great. I'd love to have some Rollz pcbs to experiment with. If you had any extra I'd be happy to send some $?

me too

Interested in the Conrad & 5Star PCBs
southphillysynths
Yeah those look great! I would be interested in a few of them, like some of the rolls or the dogvoice and deerhorn.

Would be cool to do a group buy!

Guys, I live in fairly remote area of Thailand 1 hours drive to the nearest post office and made enough for myself and a couple of friends. I really provided the info so that you could make yourself as I don't want to make a business from this.

The prices of doing this was ridiculously cheap and would be cheaper to go direct than me reposting from Thailand. Maybe guys in the States do a group order? Guys in Europe do a group order? Also you can add stuff I didn't order like Lil Sidrassi's and Gerassics etc. there's loads of stuff in that papers.zip file that I'm not familiar with.

Usually there's a minimum order of 5 PCB’s.

To give you and idea of prices.........

Small pcbs say 4x4cm like the Rollz @$2 for 10 pieces. Avdog / Ultrasounds / Gongues were $5 for 10 pieces. Bigger pcb say 10x10cm like 5 star and Dogvoice were @$22 for 10 pieces. The Deerhorns are big 40cm long and were $21 for 5. Shipping @$30 from China. My order took 7 days from when I ordered to when I received (in Thailand). And I paid import duty of @15%. So look at 1/3rd of you price for shipping.

Seriously, it was easy to do. Just follow the instructions I made.
Hints - A new customer order gets there first item heavily discounted, so choose the biggest pcb (Swoop Spokes or 5 Star / Deerhorn) for your first item. Also choose the most expensive shipping as that is also heavily discounted on your first order as a new customer.

It's coming up to Chinese New Year. Do not order anything from China until after smile

The only issue I had was that a few pcb's came back with the missing pad solder on the back of the pcb. I actually contacted the pcb company and the issue with no pads on the bottom on some of the PCB's is because there was no pads in the gerbers from Peter. It's not an issue with the pcb company. This happened with the Rollz6, Anti Swoop, Anti preamp, 2 lots of Deerhorns. I guess they are still useable if you solder from the top.

All the other stuff I ordered was fine. The actual pcb quality seems really good and for the price, you can't go wrong. Everything came back shrink-wrapped/bubble wrapped with order / batch numbers on etc so it traceable / traceable if there are issue. There's a quality control ticket per item that you fill in and upload photos if issues. They replied back after a day. But like I say, will they work? I've not made made any but they look promising.

Thanks anyway for the info! Guinness ftw!
