Well I've put one together. Pictures are just uploading to picasa.
What can I say - it works. Mostly - there's a problem with the LEDs but I think that's what I get for recycling.
To be honest though I think I'm going to pass on the manufacturing of these. Because:
1. I hate soldering DIN plugs.
2. The 5v supply ideally benefits from a CBM cassette plug.
C. The parts cost is very high for small numbers.
IV. The boards take a long time to etch.
3. In a few days I'm going to be quite busy making other things...
Now I'm happy to help out in terms of burning firmware into chips etc, but the rest of it isn't appealing to me at the moment. The board files are free for anyone to use and I'll help with those in any way I can.
All in all, at the end of the day, I think that the NKC ones are better value.
Still, it was fun PICTURES
