Re: [time-nuts] Flash!!! FA2 works on Arduino Tablets !!!

I have no way to test this, but I wonder if one can charge the tablet wirelessly while the USB port is in use. Assuming the tablet is capable of wireless charging in the first place. -Pat (KG5YPQ) On Sun, Oct 20, 2019 at 11:01 PM Didier Juges wrote: > The interface from the FA2 is USB, so

Regarding analog clocks, what is the groups opinion on these Atomic WWVB Signal Radio Controlled Clock Movements? I ordered one from China but it isn't here yet. I am hoping that I won't have to change the clock for DST. They are only $15. https://www.klockit.com

[time-nuts] Ancient HP 5065A on ebay

There is an 5065A on Ebay that has the earliest SN I have ever seen. 808-00031 or maybe 00051? Maybe the first one sold? If the lamp oven has not fried it might be a fun project. It has the Patek analog clock. Cheers, Corby ___ time-nuts mailing

Hi. Personally, I would not trust an "ISP" based NTP server!  From personal experience, they tend to run them on the heavily congested border/gateway systems.   As you can find and confirm using the usual network routing and diagnostic tools. As has been said, local GPS / Internet sync'd servers

I scanned the NTP pool last leap second and relayed the list of offenders to Ask. NTP pool servers may use a mixture of smeared and non-smeared upstream servers. Yuck. While the NTP pool has limitations it is widely used (and abused). NTP servers outside of the NTP pool may also be imperfect.

Hmm... On one hand the seller claims ..."is fully functional" On the other hand the seller writes..."untested" Strange that it has the light brown type cover plates. My old s/n 848-00131 has the dark blue covers. for $333 I would have baught it untested but the shippingto Sweden is another $209.

Hi I think that you never really know what’s what until *you* can poke at it and try to fire it up. If the device (any device) was run for decades, parts probably were swapped to keep it running. Bob > On Oct 21, 2019, at 4:16 PM, Ulf Kylenfall via time-nuts > wrote: > > Hmm... > > On
