Hello everyone,
let me grab the opportunity to post here on muffwiggler and share with you this project from Intech Studio.

Otto's DIY is targeting the eurorack module builders, whether expert or just eyeing the idea of building own modules. It's really handy to test out schematics while staying in the eurorack format. At Intech we used the boards a lot to experiment, long story cut short, we liked the concept, thought others might like it as well.

Open for discussion, your thoughts on launching something through crowdfunding pages and of course on this product, campaign in general.

Yeah I like this idea, I don't eurorack, I build in 4U and have used these from Ken:

https://www.cgs.synth.net/modules/cgs124_bread.html

Adding the power header and buses is a good idea IMO... I think you have to 'stripboard plus' or people would just use stripboard!

there are a number of similar project, like:

https://www.tindie.com/products/dhaillant/eurorack-stripboard-pcb/

and

https://www.muffwiggler.com/forum/viewtopic.php?t=161083

In principle I also like the idea .... but it all comes down to price. Stripboard is cheap. And if I have to pay $15 for one of these, I might as well make a proper pcb.

Nice one!

Seems like a good idea, personally Im confused why this needs $5k.

Question is on point. The related third party components are the reason for that and to let us create an inventory for these panels, components. Also the prices of the perks after the campaign depends on the outcome of the campaign itself. We wish to continue developing this project. To get down to a reasonable price break for the PCBA for the PowerBrick and the TS sockets for example, which are the upgraded PJ301M-12's from QingPu, we need the support.

There are great eurorack module prototyping projects outside of this one of course! Otto's DIY is on the other hand approaches the eurorack module building from an other point of view. Based on our and others experiences we designed the boards to fulfill specific requirements. Some of these are the following: create front panels quick and easily, make skiff friendly builds, realize projects in a durable format, don't kill the rest of our modular while testing and so on. Tried hard to put together and highlight every idea behind Otto's DIY in the indiegogo pitch video.

Thank you for sharing your concerns and opinions, appreciate it!

Sure d'oh!

I don’t get it at all. The hard part (for me) isn’t the hardware - it’s the circuit design and layout.

I also wouldn’t plug a prototype module into my rack - I’d be far too scared - so the eurorack format and power headers are redundant for me...

Breadboard in a test environment and then strip/vero-board or PCB works well for me....

Am I missing something? Not sure what problem this solves.... sorry...

For me2, but I only make prototypes on perfboard Mr. Green

Alternatively, one could just learn kicad and use one of the many pcb prototyping houses. Cheap & easy. There are many, many circuits on the web to experiment with & once you get used to drawing (copying maybe) schematics and laying out boards in kicad, it goes pretty quickly.

My 2 cents.

Smt and proper circuit boards make strip board look like something out of the 19th century.

I would wish anyone the best of luck with any project...


but i find it hard to see the attraction.

Entirely off the top of my head, i would think that the following would be of more interest -

Say a section of bread board, with panel mounting hardware (ie so the breadboard mounts to a panel) with a pre-drilled panel (a selection of holes for jacks and pots) and, say, a power header on the breadboard would be more task-specific?

Again, i wish anyone well, and hope that you find a market, but im at a loss to see how this really sets itself apart from some generic protoboard, and a quick aliexpress order?


I would suggest that you need to differentiate further from what can be obtained off-the-shelf to pick up sales in numbers?

(but dont take my word for it - what i think, and what the market thinks are normally very different things!)

Hee hee :-) I ought to bite the bullet and learn to order a factory pub (wrt custom boards I’ve only ever etched my own boards - never sent them off to be made!) I am trying to learn Eagle at the moment though ! (Inspired by the Mutable Instruments schematics)

Slowly being dragged kicking and screaming into the 20th century (maybe in a few more years/decades, I’ll make it to the 21st)


All the best to the guys selling this though - hope it works out.

I like to build modules using old (80-ties) material and if that is not possible there are smd to dip converters Mr. Green

I believe the point of eurorack synthesizers in the 21's century is to get you away from the computer screen, turn of your brain, turn on your imagination and have fun!

Otto's DIY helps you realize a project in a couple of hours instead of designing your PCB (couple of days) then sending in off to get it manufactured (10-20 days) assembling and testing it (couple of hours).

If you wish to design your own PCBs, maybe you even want to sell them later, you still have to build physical prototypes. (unless you want to spend another 2-3 weeks waiting for your "RevisionB" PCBs because you made mistakes in the schematic.)

Building the prototype on breadboard is not gonna survive 2-3 weeks while you are waiting for the PCBs, unlike a perfboard build.

If you build using Otto's DIY panels, your module will fit in your Eurorack system perfectly and while you are prototyping your rack is going to be safe thanks to the PowerBrick extension. (Short circuit protection, over-voltage protection, supply noise filtering etc.)

Hi wigglers,
got the first build video up on YouTube.

This module is a simple arduino based clock source built on the Stripboard-480 & PowerBrick.



Sources are up on the intechstudio GitHub.

Working on more stuff related to Otto's DIY. Next video will be about a Korg monotron mod, eurorack'd with a Protoboard-1120 and the PowerBrick. Also have an analog sequencer and power supply project on the list.

If you haven't checked out the Otto's DIY campaign yet, here is the indiegogo page. thumbs up

+1 for Julian Let the market to be the judge : ) Btw, good to see homies from Hungary! Good luck guys!

Big ups for the support! nanners

Hello everyone,
here is a small update on the Otto's DIY project.

We started to arrange future orders on the different parts of Otto's DIY kits. Great news that we are sure the TS sockets will be included in the Bronze, Silver and Gold packages.

The TS socket is the PJ398SM, improved version of the widely popular PJ301M-12 socket. Fits perfectly the Otto's DIY ecosystem.

Also the second build video featuring Otto's DIY and the Korg Monotron Duo ribbon synth is online. A good example how Otto's DIY may be utilized, the small synth reborn as a CV controlled eurorack sound source.



There is still some time to grab your Otto's DIY package and support the project. -> indiegogo Otto's DIY
kertikristof
Less than 24 hours left from the Otto's DIY campaign. You can still join the backer's team! wink

We are thankful for all your comments, feedback, likes, shares and support. By now we are sure that the TS sockets & 9mm potentiometers will be part of the corresponding packages.

Hi,
on the 10th of April we shipped the Otto's DIY packages to our backers. Received handful of feedback, thank you for your early support!

We launched a webshop for Otto's DIY related goods. Also extended the product range with 1U pulp logic style prototyping tiles.

No love here? I just discovered this, but there are some first instructions up, and people seem to start building with these. This looks very promising.

I will definitely go ahead and try to get into the instructions, and order one IF I understand them. I already had a course on electronics where I learned how OPs work, and stuff like that (loong ago), but damn, the tutorial is "a bit" to heavy for me without additional resources.

The parts for the small oscillator are at 45€, so this looks exactly what I imagined for a start woah

Hi Kravvall,
unfortunatly me and Gergely aren't very active on muffwiggler. But, the Otto's DIY facebook group is worth checking out. Happy to answer any of your questions! https://www.facebook.com/groups/ottosdiy/

Currently we are overwhelmed with an other project of ours, the Grid modular MIDI controllers. But Otto's DIY content will also come soon with a DIY power supply (+ video tutorial) and in the next year maybe a new chapter of the cookbook... smile

Anyway, glad you like the project, come and visit the fb group. wink
