A good result Nick. There's so much interference around these days - I wondered why my own MSF driven clock wasn't updating any more and it turned out to be my pond pump. 🤯
@@BobAndersson Hi Bob, as we all know there are so many switchmode power supplies around and they are a massive noise source and it doesn't help them moving the transmitter up to Cumbria. Its so much weaker down south than it used to be. Thanks for watching
It's a conspiracy Nick - they shut off the MSF signal as soon as you pop in the lab to test the receiver! Same thing happens if I ever want to test some solar panels - weather turns from a bright sunny day to overcast as soon as I step outside. The 60 kHz receiver board (5V) I bought is from an outfit once called "Universal Solder" but now called "Canaduino". They'll sell it with a 77 kHz crystal, too. It's reasonably easy to hook up the receiver board to a small Arduino board and decode the PWM BCD data into time for a 7-segment LED display; quite a bit smaller overall than the Old School but Very Cool Z80 solution. There are also older CPU-less solutions which clock in and buffer the BCD coded time directly to the display. Big boards, beautiful fascinating things, lots of shift registers. The Canaduino board does quite well here, even in the Faraday Cave, but I'm only 60 miles from WWVB. They better not move the transmitter! They did threaten to shut it down a few years ago. That's an impressive rod you've got there. :^) Great result! Loved it.
@@matambale thanks for your kind words Joe. You know a hell of a lot more than I do about what goes on with all that data! Many years ago before this clock, I tried to use the once a second pulse to clock a TTL or more likely CMOS clock that I built. It kinda worked but was never going to fly! If the signal was lost then it would just stop working. A lot of these modern radio clocks use the 77 kHz from Germany which seems as good a signal here. Thanks for watching Joe.
