A few years ago I bought and old bit of Solatron kit on eBay for around £15. It had 12 NIXIE tubes in it and was totally unuseable. So I strpped it and designed and built a clock for fun. Clock source is a CD4060 and CD4013 with a 32.768Khz crystal. Counters are 6 x CD4017's driving MPSA42 transistors for the NIXIE's. 180 volt supply is a switched mode type and the LED's are controlled with a PIC16F737 to give 16 selectable sequences. Time backup is 10 hours from a 4 farad capacitor. The base is beech and the case Perspex.
Bardzo przyjemnie to wygląda. Dodałbym jednak kilka diód by pokazać też jakieś dodatkowe informacje. Nawet prosta rzeacz jak podłączenie internetowej pogody czy informacji o poczcie.
The colons are swithchable to flash every second or remain on continuously. They just happened to be off as I rook the photo. Although the neons look large, the spot when lit is just right. Thanks for the nice comments.
That's a nice build. 👍 I should learn to make attractive cases. It can hide a lot of my messy soldering and wiring. 🤣 That old kit you bought was a bargain if only for the nixies.
I notice you didn't enable the colons. Out of proportion to the digits?
