Mike,

Are there any crystal oscillators left?

Yes there over a dozen left, (more if I do another run of picking and testing).

PM me for my Paypal details, prices are in the thread.

Hey nice PCB, just delivered. There is a problem though.
The build instructions and the BOM have typos for the resistors, I can probably figure this out but thought the typos should be noted.

A:
R11 is mentioned twice in the build manual "install wire links for R11, R14, R16, R23, R25, and R27. Do not install anything in the positions for R11,R13, R15, R22, R24 and R26."

B:
R29 and several other resistors are not metioned at all in the build manual

C:
R2 is listed twice in the BOM
"- R2 = 4K7
− R2, R3, R4, R17, R18, R19, R28, R30 = 1K"

There might be others, I didn't check it all

So....+5V Gates/Triggers or +10V Gates/Triggers?

Discuss.

That's what I was thinking: use 10V and if you need less, you can always attenuate it.

Built this and it worked first time, starts, stops and resets the Klee just like I imagined it would, no errors from me or the build doc. I have to get a panel for it, so no pretty pics yet. A great piece of gear, well done guys and thanks once more.

Hey George, this is fun, isn't it?
And i agree, Dave's circuit is amazing. I was able to open a new chapter in my music production process.

Hi Dave & Matthias,

excellent work sunny

Just finished my experimenter board built (German: Lochrasterplatine) of fonik's VC Master clock to drive my klee and a subminiature baby 8 sequencer (Thanx again Matthias for that simple but effective designs).

To sync to MIDI I realized now my MFB Urzwerg Pro clock is not working the way I expected, so I happily found this project.

Are there any PCBs and UARTs left?
I'd love to have one (each).


The possibility to expand with more switch sections looks very interesting too Wink

thanx & regards
sicpaul

Hi sicpaul.

Just found your post - sorry for the delayed reply Embarassed

As far as I know all the PCB/UART sets were sold. We'd need quite a few people to show interest for another run - Matthias is the Boss there - his department Wink

It's not too hard to build on perfboard - the first two prototypes were built that way. If you want to go that route, PM me, and I can help you out with maybe cutting out a few non-vital parts of the circuit, to make it a simpler build.
The really big part is really just the 40-pin UART - the rest is pretty straightforward.

Once I have the new workspace up and running, I can get back into a bit of SDIY again. Can't wait. Smile

cheers,
Dave

hi paul, missed your post too, hehe.

anyways, just yesterday i cleaned up my workbench and found two left M2C PCBs, however, i don't have any UARTS left.
i recommend JAMECO as source for the UART, the price justifies the postage...

Hi Matthias
... ooops, now it is me who missed the posts. Rolling Eyes
Back from holydays I'm hopefully not too late
getting at least one of the two ... or both?

Finding UARTS will be not a hundredth of the difficulty than soldering all parts on proto boards Wink

I haven't been on this forum much for the past couple years, but I'm recently finding myself needing some simple MIDI clock solution.

Any chance someone has an PCB left for sale or trade?
