What I have in mind is a huge display (well, 12 inches ;)) showing 'Sauron eye' looking in the direction of an approaching person. The orange long P19 phosphor would be perfect for that. Alternatively the Matrix like effect with the clock face made of symbols brighter just enough. And moving around. Saves from trace burnouts. Display activated by motion/presence sensor. Otherwise HV off, filament at ~0.3 nominal. My plan is to use raspberry pi for the logic. Deflection is a bit tricky. 8bit DAC is not enough and what's really tricky is the amplifiers able to deliver over 1kV. The 10kV acceleration seems reasonably easy in comparison. Anyway, probably it will be maaany years till I am able to dive into this project. BTW, the Dumont tubes look very modern - flat screen, metalized - state of the art. But the Russian has the real appeal - curved screen, permanent hand writing, vintage shape of the funnel.Marcin On 08-Dec-16 02:24, Nicholas Stock wrote:That's a beast! 10KV on the PDA. I'll let Grahame chime in on whether the add-on will work with that tube, but I think it should do. I have a couple of similar 12ACP19 tubes that I'm hoping to make a clock out of....not your average desk clock either..;-) On Wed, Dec 7, 2016 at 4:43 AM, Marcin Adamski <[email protected] <mailto:[email protected]>> wrote: No, sorry the Dumont is K2249P19, not K2261P7.
