[GreenKeys] Interesting Piece eBay

[Nick]

Jeff,

Your clock is much more professional and elegant.
I used an IV-18 vacuum tube for my clock creation with a 150VDC power supply right next to it, a bunch of relays, a PI with a Python script, a morse code sounder to create an annoying alarm and bunch of blue, green and yellow LED's to go crazy whenever the set alarm time kicks in together with the sounder.

Three pics of my childish alarm clock attached.

Not bad at all for an amateur who doesn't know much about electronics and programming. I occupied myself, had fun and learned a lot - that's what life is all about, right?

They look like Numitrons. 5vdc firmaments for each segment.

Like in my Thermo Numitron Clock https://wiki.rodaw.com/wiki/Thermo_Numitron_Clock    :-)
