Mike,

Are there any crystal oscillators left?

crystal oscilators received in OZ
thanks Prof Smile

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

be sure to have the latest documentation. these errors have been corrected already. however, thanks for the pointer.

Ah..thanks Fonik..thought I had the latest but I guess not. Looking forward to getting this puppy going.

first board nearly complete , panel at 90% just needs paint and labeling.
still awaiting some chips from futurlec Rolling Eyes

always slow from them
and then to wire up, ran out of weekend now Mad

oh well will finish it next weekend i hope.
also noticed Q3 - Q8 missing from BOM - 2N3904's
cheers

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

Discuss.

i like 10V, so that i am always on the safe side...

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...

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?
