Thanks, Timko and Gordo for offering to collaborate. I suggest you focus on the build instructions document, I will continue to write the operation manual which you could review afterwards ;-)

I already created an overview of the functions for the user guide:

I think too much.

Any opinions are welcome.

No problem. Buy it.

I can start hoarding parts.

Yes you can. The build doc is finalized in Version 1 (read on...)

Concerning the documentation, I would love to try something new: Obviously, I am not a native speaker, and obviously, being the designer of the Eoo3, my build and use instructions might be sub-ideal for builders, who don't know all the details of this design by heart. This being said, I had the idea to write the documentation completely in google docs and I would open this up to anybody, who would like to contribute to improve it language and content-with the target to optimize the building experience.

Would you like to contribute? Than PM me, please!

More precise, I meant only the section where Rob writes about forming the filter caps (for solid state or tube rectifiers.... Well... You have both :-))

Don't open the amp, if you don't have the experience (Can't judge) and don't need to. It's really dangerous.

I would follow the variac startup procedure described here:

https://robrobinette.com/Tube_Amp_Startup.htm

... Without the light bulb, your amp shouldn't have a shortage.

Do I get it right? You live in a 110 volt region now and want to run a 220 volt amp there? Also... How could you forget a recto in a storage place?

The documentation (and source code) is growing, so here is the link for the complete folder (many documents still in progress, but the build doc will be good enough to build your own by the end of the week)!

Sneak preview to the build instructions is here. 29 pages already, including many pictures, still some work to do!

Where is the link to the code?

Great work!
I'm at the beginning of a similar project, will probably steal some of your ideas

Sure, go ahead! If it is arduino-based, you can get my code as well (open source). Start a thread about your project, after Eoo3 kept me busy for almost half a year now, I want to see other's people blood, sweat and tears ;-)

[25,- EUR]

Updated Post as I ran out of enclosures AND German Post changed their conditions:


PCBs:
The set of 6 PCB's for the looper will include:
- 15 Jack PCBs (on a v-slotted board, you only need 8 of them)
- 8 Loop Button PCBs (on a v-slotted board, you need all 8 of them)
- 10 Preset Button PCBs (on a v-slotted board, you only need 7 of them)
- 1 Control Board (for the Arduino Nano, the Shift registers, the Power connection, Midi in and out and the Button connections)
- 1 Spillover Board (for Amp Switching and Spillover Loops seven and eight)
- 1 Relay Board (for the Input Buffer, Loops 1-6, send/return)
- 12 Distance rings for the PCBs
25,- EUR

Shipping and packaging (EU): 5€
Shipping and packaging (Non-EU): 9€

If you want to get one set, here is the link to the preorder-thread: http://www.madbeanpedals.com/forum/index.php?topic=29576.msg286399#msg286399

I'll go thru my paperwork.  It was a lot of detective work and it was sold as wire channel for high end modular furniture.  Cost me a fortune but is very cool.  I suspect if a bunch of us bought it the price might be more reasonable.

Gordo... Did you find your source for the cable channel? I would include that in the documentation, if possible...

Thanks!

I definitely will grab a set of the Eoo3 boards!...i noticed the 5v relays used are different from Linda.

Correct... No specific reason for that, though. I use these smaller relays in small enclosures and they save some space on these PCBs as well. They aren't more pricey, so I use these for the Eoo3 now.

Nothing but good news today:

The new relay board arrived and it's working perfectly:



While soldering it in, I discovered a cold solder joint in the mute-while-switching-block. Fixed it, now there is only a little, totally acceptable pop noise when switching EVEN IN SPILLOVER MODE in loops 7 and 8.

So, it's almost done. I would love to add a mute function for tuning to one of the loop buttons (activated when held down, deactivated with another press). Also have to write the documentation, which will not only be a build guide, but also a user guide.

For those keen on boards, I can promise you, that the boards (a set of 6 boards for one looper) will be up for sale latest on 20th of April. I will let you know in this thread.

Seems like I will need to build a smaller board. Power supply (top right), patchbox (top left) and the separate power supply for the HX stomp (9V, 3 A is too much for the palmer power brick) will go below the Helicon, the King of tone and the HX...



Still waiting for the Relay PCBs and writing on documentation.
