nhtagmemberGot My Digital Clock Kit
it arrived after a 3 week shipping adventure from Poland
I am building a 12/24 hour digital clock that uses Nixie tubes, and its all discrete components
gonna flash up ye old soldering iron this weekend but I need a new ground strap for the IC's before I socket them

nhtagmemberyeah, they probably wouldn't know what to do with a few transistors, capacitors, resistors and blinking lights
I plan on setting this one to Zulu time for my ham shack

.38supersigAw shucks, you can't give us a tease like that without telling us what tubes you are using.
568?
Single tube? Four tubes? Six tubes? A Pixie to count seconds? Antenna to synchronize with the world clock? Inquiring minds want to know...
A good flux pen is a must. Be sure to compensate for meter loading when calibrating the power supply.

nhtagmembershould be a six tube kit with IN12A tubes
if I was going to enter it in a science fair, it wouldn't be a clock - it would be a count-down timer
I have a Siglent SDS1104X-E 100 Mhz scope

Don't do that. You know better than that.

nhtagmemberI don't have any way to host photos but I will take some photos of all the parts, the two circuit boards, base and the pieces.

Try postImage. There's a free (as in no-cost) option, and you don't even have to sign up for an account.
I use it for everything except my avatar -- postimage doesn't do avatars.

ensigmaticI was thinking of getting one of those for the man cave, until I read Nixie tubes don't last a long time. Odd I didn't know that until recently, being as I weaned my electronics teeth on glow-bottles.

nhtagmemberthanks for putting these up Mark - appreciate it
this clock is going in my ham 'shack' but I'd also like to make one for my observatory and I need a countdown timer with a chime for tracking aircraft check ins

HRKLooks interesting, like to see it when you have it finished...
