I really like minimal invasion when doing a conversion - although that might be tougher with nixies than with CRTs. What if you actually kept this unit as a distance measuring device, and built a stepper-driven mechanical slide (like the head of a printer) that would be stepped to represent

Yes, it's another Firesign Theater quote. But I am trying to work out if this multiple Klein bottle could be filled with gas or not and if so, which parts would glow? Answers on the back of a banknote of your choice please. I can't wait for Nick de Smith to make me one, now he has the skillset.

You can't fill a Klein bottle with anything as there is no inside to fill. Anymore than you can colour in a Moebius strip with two colours without them touching. Tom Harris celephi...@gmail.com On 25 March 2015 at 08:36, Quixotic Nixotic nixci...@jsdesign.co.uk wrote: Yes, it's another

Looks like it's from a CMM. Had a similar unit at last employer. Lost track of it 25 years ago when they upgraded to LED units. On Monday, March 23, 2015 at 9:39:28 PM UTC-5, Kerry Borgne wrote:

I agree with the minimally invasive route. Is this a digital caliper of some sort? In which case there would have been a device plugged into that input with which to do the measuring. If you have that and it works then a physical representation of the time is a neat idea, if you can drive it with

That will almost certainly take a quadrature input from a encoder and increment / decrement from that, so you could make a circuit to pulse it up and down to simulate time without modifying it at all. That would be a challenge at least. The Quadrature input will almost certainly give +5v and
