Nice tubes, had a look at some on youtube. They still seem relatively large. If there was a dekatron that would fit inside a B4998 envelope it would more appealing.
I think family and work is for most of us the reason why projects take more time than initially planned :-) I usually start too many projects at the same time because I want to try out all of them :-) Michel On May 12, 8:32 am, Dekatron42 <[email protected]> wrote: > Ohh, I would go for just one watch if I had the parts, mass production > has never been my focus as I just do these thingd for fun and because > I can. > > I guess that the Burroughs Self Scan design is the smallest "dekatron"- > like object there is, I have not seen anything similar from any other > manufacturer.
