content: I like itthough I am a sucker for anything with an evacuated glass tube that glows, or gas filled, for nixiesbut this kit looks nice and well made when assembled, a little pricey but not too bad.

content: Friend of mine designed and built one last year, only with characters not the nice analog version. It can be difficult to get the nice small crt's , so first try to score those before you start.

content: Looks to me like a good way to burn up rare cathode ray tubes. Maybe a switch could be incorporated to cut off the cathode current when you're not home?I have a nice collection of DG7-32, 2AP1's and a couple dozen other CRT's ranging 1" diameter at about 5" diameter. Don't think I'll be making a clock out of any of them.

I like to see people having a go
