I remember opening up those military crystals and sanding them down with Ajax cleaner to raise the frequency or rubbing a little solder on the plate to lower it for CW transmitters. High school days.  -- David VanHorn Lead Hardware Engineer Backcountry Access, Inc. 2820 Wilderness Pl, Unit H

not so much the noise from the interface its the USB device itself i’d worry about as USB 3.0 generates RF signals up to 3 GHz. And also has fairly strong signals in the 2.4 GHz ISM band. Content by Scott Typos by Siri > On Dec 4, 2019, at 12:07 AM, David Van Horn via time-nuts > wrote:

I suppose this is vaguely time-nutty.  I have an application where I need to take USB into an EMC faraday cage. I see a number of optical fiber implementations available, and the prices ($200-300) are acceptable, but I’m worried about noise that the downstream end may cause, since it will need

[time-nuts] Most popular NMEA sentence with date and time?

I'm helping a friend with a hobby project, a "Countdown To Christmas" clock. I haven't looked at the NMEA docs in a while or three.. What's the most widely supported sentence(s) that will give me date and time? We're doing one Arduino to grab the data from GPS and talk to the others, which

Re: [time-nuts] Bombe clock

Years ago, I wrote an "enigma machine" in Atmel AVR code, just for fun. I'd love to see the relevant details from the Bombe and write up a version in the AVR. From a room filling (and heating) contraption of relays and tubes to a tiny chip. -- David VanHorn Lead Hardware Engineer Backcountry
