Using Logic Systems

I have always though a basic arithmetic calculator would be fun to build from discretes... Maybe when I'm retired and have lots of time, but probably not as I don't have the patience...

This looks fun though...

I'd probably go with the Nixe tube version to even add more coolness... Same guy...

http://tube-clock.com/

after much searching and looking I cannot find the schematic for these, I KNOW that i have the parts for these (other than the tubes and the specific board), and on their site I cant find a way to contact them, I would like to just get the schematic and the board (hopefully for less than they want for the whole project kit... 200 without the plaque... YIKES)

any suggestions on a schematic??

Honestly... Details was the only link that I did not click, and I am so disappointed in myself now....


Thanks haha

So are you going to impress us all and do a wire wrapped version on a perf board

Not sure, that would be one massive perf board, and Im not sure if Id have the patience for wire wrapping...

I asked the guy and he said he could ship me the board only as I have most everything else and he said he could for 99 with shipping included...
