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

Re: [neonixie-l] Re: One more from the depths.... what would you do.

2015-03-24 Thread Andy Tefft
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 sufficient precision.

Otherwise perhaps you could just simulate whatever electrical signal it
would generate and achieve the same effect. Again, the precision might be
tough.

I started a counter-based clock on this principle - I just output pulses
appropriately to increment the display as needed. The only modification I
made to the counter was to give myself access to the reset signal so that I
could reliably start counting at 0 when I needed to.  It was a neat project
but didn't make it past breadboard stage.

[neonixie-l] One more from the depths.... what would you do.

2015-03-24 Thread Oscilloclock
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 timely physical distance? The controller would step the 
head a tiny amount for each second, say 0.1mm, so 6mm for 1 minute, then step 
from 10mm to 16mm for minute 2, and so on. 09:13:25 would mean 9.1325m though, 
so perhaps using 3 stepped sliders and doing an analogue multiplier on the 
input would be more realistic. The result in that case would be really 
interesting to see, like the carriages on 3 old typewriters stepping along...

Of course this could be done with voltmeters or other readout units, too. Just 
a crazy idea.

[neonixie-l] Re: One more from the depths.... what would you do.

2015-03-24 Thread Alex
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 
Ground out as well. Try connecting a rotary encoder to it and see what it 
counts in (step size). If you were really cunning you could very quickly 
count backwards / forwards at mid-day and mid-night such that you could use 
the + and - marker for AM and PM. It would mean you circuit would have to 
pulse leading or lagging B channel depending on wither it was counting up 
or down but its all just software in the end :-)

Nice find, I parted a dead mitutoyo DRO from that line, but about 20 years 
younger (non nixie), a while back.
