Would be cool to rip off that microcontroller and use an arduino to make a more accurate clock and other readings like time/temp/humidity/…
Big Clive needs to make a video named "Big Clive Lock"!
By the way, for some nostalgic but also modern challenge can be using Zilog's modern Z80 based MCUs, the eZ80 stuffs. It has got flash, RAM built in, but also works on external bus as good old Z80, if wanted. It has many integrated stuffs as well (being an MCU, no wonder). Zilog even offers ones running @ 50MHz, and much faster even on the same clock speed (IIRC, Z80 needs something like 11 cycles for 16 bit addition, eZ80 can do that in a single (?) clock cycle, regardless of the clock frequency exactly). And it's quite Z80 compatible at code level (well, undocumented opcodes can be a problem, I guess, if someone use such a things at all), but it also has another mode, when it can address 16Mbyte (IIRC) of memory directly by extending registers to 24 bit in size. But it's quite OK to use only in Z80 mode with or without the internal resources, mostly. I met one problem only: the usual IN/OUT opcodes refers to the internal peripherals, it can be a problem if some wants to connect devices to the bus. Surely they can be used at higher I/O addresses still, but it can be a compatibility problem with existing Z80 projects using some certain fixed I/O ports. Then it's not easy to use eZ80 instead of Z80 without major reorganization.
Yes, your face is definitely all distorted! Like mine; perfect for radio. ;-D Thanks Julian.
being ex-radio, its great to see the face behind the voice! great videos
Bought one of those for my kitchen, haven't noticed any time error.
Love the clock but WAY to spendy for me!
Enjoyed the video… down to earth and honest… pretty rare these days…
How about a new project where you replace the guts with a ESP8266 that can automatically get the time via NTP on the internet. Then it will solve you pet peeve and make a nice project! 🙂
i have bougt this clock on ebay for ~12 US but i like it too
