He'd have absolutely loved one of these CRT clocks, no doubt.

    3/09/22: I received mine after watching your video but it took awhile before I could order it. Mine came packaged exactly like yours, covered in bubblewrap only. I'm surprised yours survived all the way to the UK! Mine was delivered in the states and came to me with part of the case broken. The back end piece that accomodates the neck of the tube broke off the rear plate & it was in several pieces. The front of the tube was laying down inside on top of the electronics. Disappointed I was, it was a beautiful piece, had to send back for a refund. Much more care was needed in packing a delicate instrument. So if anyone is interested in buying this, I hope you have better luck. As of this comment, it's $600 for the fully assembled unit or $500 for the kit version. Great review on it, it's what finally made decide to get one, but maybe later now.

    I've always wondered why no one ever adds a motion sensor to these nixie and CRT type projects.

Just having the brightness auto-dim would help save that phosphor from burn in.

      The limiting factor would probably be the sound card / audio source - human hearing tops out in the 10s of kHz while pretty much any CRO I know of will at least be in the MHz. As for weirdness happening when other stuff is drawn - is there some AC coupling going on (either in the sound card / audio source or in the scope)? I think this would cause some unexpected artifacts and make stuff self-center over time. The gain in one channel of my scope is a bit up the creek and this failure / change in the amplifier behaviour also causes artifacts / skews shapes at moderate frequencies.

So many people at the hospital where I worked left it on that channel that eventually we had a lot of CRT televisions with 88:88 burned into the screen.
