Thanks. I did notice the jumpers but as the documents only mentions them for feeding back 5V to the bus I though the 7805 might be necessary to isolate the board from the bus for some reason.

As I ...

Something I'm not entirely sure about from the other thread and the docs: does the board actually need it's own 5V power (to isolate it from other circuits), or can it draw from an existing 5V supply? ...

Yes sold some stuff I rarely used to get other things, and then got bogged down in repairs and builds for others. But getting back into my modular now...

1 PCB plus UART please Very Happy

I myself use the WS81 to great satisfaction. Does anyone know what the extra 'E' stands for in the WES line? They look identical to the WS ones.

Funny how the single most common and cheapest transistor in Europe can be so hard to find elsewhere in the western world...

By the way, I've redrawn scans using Abacom's Sprint Layout, which might be the only pcb design program that let's you use transparent scans. It probably easier than something like photoshop since yo ...

One of the things I'd like to make is a somewhat generic module, with several inputs, outs, knobs, etc. 24-bit, 96kHz.

Something like the Digi-Mod?

I think Newtone ship to Belgium:

Curetronic has a PCB-layout of the Roland 121 replacing the 662's with 6110's;
http://www.curetronic.com/curetrbau/neubau/100m.htm

I built that and it works great.

e) Although each chip has 3 rows of text, the text in the top row, such as "8836A", is unique to each chip.

That is the date code (1988 week 36). So if they are all different, they are ...

DIL are being very rude by the way. They are not answering my questions in their e-mail replies and don't seem to be interested in my order in any way. So I won't buy from them.

Thanks for that.

Care to enlighten us on that source?

Indeed, and some kits that need them are sold without them, so I guess his stock is really low.

The only source I know which has been pointed out is Bridechamber, but when I asked a couple of weeks ago Scott only had a few left and was selling close to $20 each. So that's not a real source in m ...

just for clarification:

Strange thing is...I would think more people would have had these problems. Perhaps Fonik and I were just unlucky?

I'm not sure but I think the ones I got are fine. They are in my Threeler. But i ...

Not without a lot of effort. It's polyphonic, which doesn't mix well with cv/gate, and it's completely CPU-controlled. So it requires loads of extra hardware to make it accept any kind of cv/gate.

Elektor sell their articles online as PDF, so anyone who wants it should be able to get it. I have the hardcopy. But as was said above, it's just an LFO+VCO. And the Elektor one is HF (to test rece ...
