... Rene, Please... what is the pinout for that FET? Google gets me as far as a TO-251 package but I'm danmed if I can find out which pin is gate, drain,...
Hi Mike, attached you will find an EAGLE lib with Z566M and MAX770. Z566M have 2 different packages with 1.3 and 2.0mm drill diameter. 1.3mm is for sockes from...
... Jim, I have plenty of photos taken with a film camera. I'll get some of the better images scanned in, and post them later on. The "Zot" segment would make...
Hi neil, The irfr320b is equivalent with the buz80 also the pinout is .When you look for a datasheet off the buz 80 you have the pinout I used the buz 80. Hope...
... Indeed ! The part is available in the UK at www.rswww.com for a mere 44 pence ! Why don't you drop the schematic into the 'Switched mode' section of the...
... Thanks for that! I used a default 'power fet to220' package in Eagle and all the pins seem to be in the same place. Which means that version 7 of my design...
Hokay, I finally decide to freeze the design of my clock... and discover that the processor I was going to use - the atmel 4433 - is now much harder to come by...
... You should be able to replace one with the other. Minor signal differences can be made up for in software, although here I think you'll be fine. ...
Tim, Thanks for this - I haven't written any code yet so the family doesn't matter (AVRBascom has an ATMega8 definition file so that should be ok). Power on...
I created a small web page to show the progress of the nixie clock I am building. So far it is not much but at least I started it. The url is...

... Neil, A word of caution - having written no code, are you sure that your pinout won't cause trouble for the firmware? I have been around long enough to...
... David, I'm not doing anything exciting with the pinout - basically, it's just using sixteen IO pins for the decade drivers (with the bit order swapped...
That sure seems like a lot of CPU power and $$ for a clock, even the lowly AT90S1200 has more than enough power for a very complex clock and it's only about...
This has been said before, and I reiterate my point of "Who cares"? These aren't high volume runs, and no one cares about the difference of $3 or $10. It's...
... Indeed. My desiderata for selecting the atmel chip were: o is it easily available? YES o are there free tools to program it? YES o does it require any...
... Thanks, I have your earlier version. I'm building a direct-drive with crystal oscillator so we'll see how accurate it is. I have no problem with leap...
... url ... It's a start... Are you going to use point to point soldered wires on the circuit board? If so, it'll keep you busy for awhile! Ah, TTL is so easy...
and happy New Year to everyone. I'm the group's newest nixie-newbie and am following the moderator's friendly advice of introducing myself. My name is Sean...
Hi all, A Happy New Year to all of you. I have a question that is hope can be answered by anyone. I need the exact mechanical measuremts of the IN-18 tube: the...
... Hi Claus, I recently searched for this information too. It is not on the datasheets from the factory, so it may simply not be available. I'm going to...
... I ... Hello Jim, Yes, its a start, The connections will all be point to point wiring so it will tedious but fun to do. I soldered my first 6 wires last...
- but the angle is harder and might take some guessing. would it help to photocopier [or scan/print] enlarge the base and carry out some practical geometry ? ...
