[neonixie-l] Re: Finished Nixie Watch project (Pictures)

The biggest challenge is designing a high-efficiency DC-DC converter for the tubes; it is the primary consumer of energy. Generally, you will get higher efficiency at higher battery voltage. Next, you will need to determine the battery size/voltage/capacity. I gathered a lot of data about

[neonixie-l] Re: Finished Nixie Watch project (Pictures)

That is great. I plan to make a portable 6 tube clock using some Z5900 tubes, so seeing details of how someone addressed the power issues is really useful. On Friday, February 3, 2017 at 12:44:43 PM UTC-5, Craig Smith wrote: > > I thought I would post a few pictures of my finished Nixie watch

Re: [neonixie-l] Finished Nixie watch project

Next time that you're trying to machine something thin like that in a four, or three jaw chuck, plug the end that fits in the chuck with something solid that fits fairly tight, and when done just knock it out. I've had to that a time or two to keep from caving something in. Ira. On

Re: [neonixie-l] Finished Nixie watch project

I just took a look. I like the 7 segment Nixie. I have to correct an earlier post. I run my processor at 32KHz, not 4MHz. Still at 32KHz, I still can't get the power consumption as low as I would like. I suppose I am using a linear regulator to drop the lithium battery to 3v, so some wasted

I posted about 2 years ago on this forum. To be honest, I'm ashamed of it's appearance compared to your machined case. It's handmade acrylic (plexiglass), and was sealed-shut. Something failed during endurance testing, and although I've opened it up I have yet to debug it. The main difference

Re: [neonixie-l] Finished Nixie watch project

The 2uA is approximate; I have a 50uA mechanical meter, and it barely moves from 0. My DMM has too much internal resistance. Anyways, that's what the RTC uses plus and leakage in the DC-DC converters. Every 75 seconds, the RTC draws a 'spike' of current to do the temperature-compensation, and

Re: [neonixie-l] Finished Nixie watch project

2uA!!! I couldn't get anywhere near that low, even if I was just powering the PIC. I spent weeks and weeks trying to get it to run as low power as possible. I'm running the PIC at 4MHz with all the hardware turned off (i2c etc.) until I need it. 2uA is very impressive. The lathe and the

Ahh, the purple PC boards from OSH Park. I just did my first PCB with them last month and was very happy with the results. Nice job fitting everything together; It's hard to appreciate the challenge unless you've done it yourself. I got my idle power consumption below 2uA, and after 2 years my
