[time-nuts] Further FTP recovery

Along the lines of my earlier request... If anyone did any downloading from my site in the past year or so, I would greatly appreciate copies of what you downloaded so I can rebuild. I will happily reimburse any postage or media (blank CD-R's, etc.) costs. Thanks much. -=-=-=-

Max A capacitance bridge using a transformer would be a lot more stable than merely using the capacitance to vary the frequency of an LC oscillator. The advantage of a capacitive sensing technique over a light beam is that it has much simpler and potentially more stable mechanical system than w

Fellow clockers, I'm still picking up the pieces from a major FTP archive crash that lost me a considerable amount of data. Among the files lost was the .PDF manuals for the Odetics 325 and 425. The firmware files I can recover, as I still have the EPROMs in my original unit, b

[time-nuts] New T-Bolt arrived

Hi Everybody; My new t-bolt just arrived from TAPR. I powered it up, connected the comm cable to the PC and it seems to be working like a CHAMP! I have two questions for the group. 1) Is there a satellite (SV) map program available to go along with "TBoltMon"? 2) Who do I thank at TAPR for this s

When I was at the university I saw and worked on a thermostatic switch that used a standard mercury thermometer. The little thing that clipped on to the thermometer was the capacitor in an oscillator. The detector for opening and closing the relay was a high Q tuned circuit. I saw them regul
