... Hello Chris, I've finally started to assemble the boards you shipped to me last month. I have a question about the pin sockets. Which pin sockets are...
... Ken, I used receptacles from D sockets, the kind where you get a strip of them separately. I just snipped the cable crimp bit off and bent the remaining...
...Happy new year by the way, good luck with it ! Ken, the receptacles are from Rapid Electronics, part number 22-1125 They're made by Harwin and can be veiwed...
... Yes Chris, I am mentioning it because of that discussion. That is why I didn't redefine those two chrs as they are off limits because they have special...
... Ken, Chris's boards are heaps of fun and mine worked straight out of the box without a hitch. I think they are a good way of showing off what are rare and...
... available ... first. ... That's good Ken, I was concerned that I had specified using a part made of unobtanium. I think I only have 4 boards left, and...
Chris, I finally started to populate the boards tonight (yay!) I have one question. What value is R-31? I looked through what paperwork I have and haven't...
Hello Ken, that's good news ! R31 is the anode resistor and is optional. It's optional in the sense that if you use a 170Vdc power supply then you only need to...
... Hello there, No , I haven't attempted to make any special boards just for the ZM1350. Althogh I do know of at least one member of this group who has used...
... I'm guessing that more and more people will use the ZM1350 because of the cost and availability of the 7971's. I could give a layout a try, but I've never...
... I would also like a set of these. I can do a pcb layout if you are too busy, Chris. That's a bummer about Zetalink. Ray is a nice guy, but he's in a hole ...
... because of ... try, ... going ... layout... ... you'd be ... hole ... Hi John, For me the biggest hurdlle isn't to do the layout but to make an accurate...
Hey Chris, If you are in fact going to have more B7971 PCBs fabbed, I'll likely buy some more from you - I'm still holding out hope that we can find enough ...
Hi Matt, Okay then I'll try to get another batch done as soon as possible. I relaid the board on Eagle lastnight, and so far I've managed to shave a quarter...
... Thanks for that Rich, I was about to order a ZM1350 because I thought that would be the best way tot est it, your test has reassured me a great deal. I...
To the people interested in a ZM1350 design pcb, could you please let me know your thoughts on the design which I have just posted in the files section 'ZM1350...
Hi Chris, Design looks fine to me! So easy to forget mounting holes, and hole for the nipple - all looks good. I prefer the compact design as you have done it....
... The layout looks great to me. The hole for the glass nipple looks small, though. I just measured one of mine - it was 0.16 inches, the hole on the layout...
... Thanks Rich, yes I should have said that the reason that there is such a large space around the nipple hole is so that i can enlarge it later, as I do with...
The order is in adn the first boards should be back within 7-10 days. I need to change the software before they arrive but that's trivial. I'll post a message...
... I ordered a full set of parts from Digikey, so I assume you'd be willing sell the blank boards? You might want to leave the connection for the keep-alive...
... willing ... Not a problem, but out of interest what values resistors did you choose for the cathodes, I haven't begun to work those values out yet. ... ...
