Re: [neonixie-l] IV-17 Explorer Kits & ZM1350 Smartsocket Boards — Both With Tubes

['Greg P' via neonixie-l]

That eBayer has been selling a lot of Nixie related clocks, tubes, etc 
along with sex toys.  From what I can tell he must be a liquidator and I 
presume bought out a Nixie collection from someone who either passed away 
or decided to get out of the hobby.

"Pay attention, 007"

Q: Should car stereo speakers be pointed to the rear for more thrust or up for 
more traction?

A. On long trips, the 20- to 30% improvement in gas mileage you might get with 
speakers pointing to the rear is certainly worthwhile. On the other hand, if 
you drive on snow or ice, the extra traction of speakers pointing upward gives 
you added control.

I grabbed the first Explorer kit (sans tubes) when he listed it yesterday. I 
wouldn't be surprised to see something else turn up tomorrow.

Re: [neonixie-l] Jeff's Nixie watch parts layout or schematic?

Thanks, Terry. I have Christian's email, but Jeff told me before his 
untimely death that he sadly no longer had the paperwork.  So I'm quite 
desperate and hoping nixiebunny has it.
