Cool, please let me know if you indeed get it to work - after 10 days of tinkering with a similar circuit i gave up, and laid out the PCB for all those Chips... Ah cool - i'm no expert at SMPS's i'll

All right, all right, NOT the best wording choice for a message title! :) I'm referring to the use of miniature neon bulbs and such for the purpose of creating a colon SIGN (:) to separate the pairs

I have a couple of those CA3162 chips on order. I'll play with them, to verify my version. The switcher Hans uses is the MKI version of the MC34063. Its of limited use. Here's a schematic of my MK1.5

You mean the 1K off the 470 ohm. Its part of a divider, so the base of all the transistors (tied to it) see ~3.4V. I pick a voltage somewhere between Vcc (5V) and Gnd because I don't know how far the

If you want a pretty sound, you may consider a chime rod like they use in older (and some newer) clocks. www.timesavers.com has a fair selection and hammers as well. Here is a direct link to the page

The CD47 is a freak of nature! I sure do want one (better yet, 6)! I've always had a thing for freaks :). -joe wrote:

Good to know I am not the only one. (It has been bugging me for years) PS. Doesn't the B-7971 take 21ma? Michail

It's what I am also looking for. Preferrably in discrete components, even relay's. I think about two sound sources: A chime, what you can find easyly on eBay searching for clock parts. They there also

The CD47 for instance: http://www.tube-tester.com/sites/nixie/data/cd47-gr414.htm Anyway, a larger current can also be required when "depoisoning" cathodes. ______ I was thinking of paralleling the

Just out of curiosity: what kind of a Nixie would be drawing 20mA without a risk of being destroyed? Thanks, Dmitri

I just came across some old info in my files that Matsushita made equivalents of the NEO-5000 and NEO-8000, their part numbers S6135 (50 mm digit height) and S6136 (85 mm digit height) respectively.

Using a physical bell sounds like a lot more fun. If you can find one with a tone that you like, I'd imagine that an old telephone would be a perfect source for a ready to go bell / striker, and I'd

Sure. We have some photos of a small flip-segment unit, some split-flap displays, and several rotary pinball scorewheels in Photos > NonNixieDisp/Electromech <

Oh, I see.? What about just putting the outputs from each through a diode and say a .05 ohm resistor to balance the load and isolate one supply from the other?
