Yup. Otherwise the bulb would glow real bright and probably for a short time. The glow with 240k *seems* reasonable. Your current meter is connected in *series* with the resistor and neon tube, correct? -- David Forbes, Tucson AZ -- You received this message because you are subscribed

[neonixie-l] Current reality check

Hi All, I am making some colons for my latest clock with an NE-96. The suggested current for this is .5 mA. So, using a calculator, with an input of 200V, I should need around 240K for the anode resistor. Measuring the voltage across the resistor I see a voltage of around 120V. So, 240,000/120

Re: [neonixie-l] GPS distribution

I use the xbee's to get data from my windmill, it's too far away for the Linx modules. I like 'em and they are worth the price if you need the range. Also have a lot of neat features, like some ADC and I/O pins. Jonathan These are neat, too. Kind of pricey. http://www.sparkfun.com/produc

Re: [neonixie-l] Mechanical Timebase!

Tim, You could do a simple acoustic detection thing with an electret microphone. Cheap and simple and should work fine. That way nothing touches the movement or impedes it's display. Jonathan There is always a lot of discussion about various timebases for clocks on this group. One I have n

[neonixie-l] NL-840 sockets?

Hi All, Anyone have some sockets for the NL-840? I bought a bunch on a group buy with this list and am finally getting around to using 'em. I could use at least 12-14. Thanks! Jonathan www.madlabs.info -- You received this message because you are subscribed to the Google Groups "neonixie-l

Re: [neonixie-l] OT: Muntzing

An old timer I used to work with said that another reason (aside from cost) was to avoid patent infringment. I have no real idea if that is true or not, just something I heard. I do remember "Don't be a dunce, buy a Muntz!". As Nick described, it was a hack method to eliminate components to

Re: [neonixie-l] How about this weather... I ran out of memory!?! HA!

I'm guessing you could shrink the code enough to fit. Maybe post it and we can take a look and see. Jonathan No no no, the memory is much larger, the program I wrote is probably very primitive, and large. I overran the available memory BY 408 bytes. Picaxe is good for me, because I don't kn

Hahaha! Loved it. An engineer, a mathematician, and a physicist are staying for the night in a hotel. A small fire breaks out in each room. The mathematician awakes, sees the fire, makes some careful observations, and on a blackboard installed in the room, does some quick calculations. He e

Re: [neonixie-l] US power grid frequency tests.

What I meant was not a GPS/WWVB thing, but that one could generate a 60Hz signal and then TX it via RF, with each clock haveing a RF reciever to RX the beat. Won't set the time/date but could be a less expensive way of giving clocks that need a TTL/CMOS 60Hz beat. - Original Message -

Re: [neonixie-l] US power grid frequency tests.

this point? Sparkfun sells some pretty small GPS receivers for about $25.. Course, if you're into WWVB, digikey has a WWVB receiver & antenna for $10.. although for my clock, I needed to replace the original tuned loop antenna with a larger one. -Adam On 6/28/2011 11:23 AM, Jonathan Pe

Re: [neonixie-l] US power grid frequency tests.

I wonder if an adaptation of my GPS time system mught work. I have a central clock that reads the GPS and then sends it to the other clocks via RF. What about a central clock that sends out a 60/50 hZ beat via RF? RF receivers are fairly cheap, and then you only have to calibrate one xtal or wha

Re: [neonixie-l] Motion sensor board

Terry, Just so you know, you can buy premade motion sensors on a similar size board, in case you don't feel like ordering etc. I have one on my clock because I live off the grid and every watt is sacred (sung to the tune of "every Sperm is Sacred" by Monty Python). I found placement to be impo
