Japanese Nixie Watch

[petehand]

A few years ago I noticed that pretty much all the IN16s appearing on Ebay were being bought by a Japanese customer, in lots of 1000. I wondered when they would reappear.

IN16's are some of the flakiest nixies I've worked with. Putting them in a watch seems a little risky to me on a replacement basis....

In what way are IN-16's flaky? Short life span (no mercury?), prone to shorts and/or cathode poisoning or what?

I've been thinking of using them but never got around to it.

I had a lot of IN-16's leak....usually a couple months after using them. They'd glow a little brighter then done. Not sure if there was a specific batch that was more prone to this than others, but they have a reputation from others I've spoken too...

I've made half a dozen IN16 clocks. The only one that failed is the 10 hours '1' cathode on my Altoids tin clock, which has gone open circuit. The '0' and the '2' still work, in 24 hour mode.

Pete -- a few months ago a post appeared here that implied you had passed on -- I assume the reports of your death were greatly exaggerated?

Glad to see you are still with us.

I have one of their square watches. I also have experience repairing one of them. It had a very poor quality lead trimming and soldering job on the tubes. 

The square watch has a seriously dim display. You can't see it well at all in the daytime, even indoors. I suppose the huge power transformer is a fix for that problem. 

[petehand]

Oh, yes indeed. Reports were greatly exaggerated. Thank you for remembering me.

I glance at the digest most days, though I missed the one about my demise. I seldom post because I haven't done a nixie device in several years now. Retirement has turned out to be an altogether busier place than I anticipated and I haven't had time to be a hobbyist for years.

Pete,

As I recall, part of the thread involved someone wanting documentation of your 4LW clock. Specifically the instructions for operation.

I looked through what you sent me some years ago, but I don’t have that part of the literature either.

I have not built the clock yet. I need to buy 1 more tube. Man those things got expensive!

It was me asking for the Pete Hand FLW clock documentation... I thought you had passed away as well.  Wasn't a bunch of your stuff sold on ebay?  One of the sellers sold me a clock with tubes and said they were one of your relatives selling your old clocks and tubes???  Geesh I can't spell this morning.
