It is, indeed. E.g. by looking on remapped sectors on traditional HDD you may see trend that drive will die soon. Selftests are only way to check surface before you will hit it with real files... On SSD the most important is wear out and us

Yep, and this release finally adds NVMe tests for the drives supports it.

nice. friend of my grandfather had similar and it was USSR DIY. It had 2 PCB boards full of transistors and other elements to drive them :) At that time no lcd was available for amateurs, so it was a natural, non-vintage choice :)

Interesting, in ex. USSR and Czechoslovakia i am aware only about "2 wire" systems, but i heard also about "IBM" one with a 3 wires, so now i know what it was for, thanks :) Here master clock was producing 1m or 30s dura

thanks, i don`t remember, may be it was something on my side. Anyway, i am happy with current implementation, so no need to migrate. Will try it on some next project :)

Oldest electrilcal mechanism from pragotron, was produced in 195x-196x years, see https://f.aukro.cz/images/sk6961755962/c15a8263-ced4-4e31-a3... for the photo.

In EU using DCF-77 probably would be more practical. I am sure that similar radio-s are in US too.

Nice :) This mechanism is less advanced, when there no impulses it just sleeps. BTW, same company (pragatron) been doing very nice "digital" clocks with the "rotating" digts, e.g. https://f.aukro.cz/image

I was looking on acetime but it was not working as expected on ESP, so switched to Timezone. I will add screensaver to my code soon to protect OLED, good suggestion.

by samm_cz 6y ago
you can easily convert any cheap clock mechanism to such :) But my intention was to keep all original mechanic.

this device was not connected to AC input. And, btw, few yrs ago in EU AC based clocks had an issue due to problems in the grid (frequency was < 50Hz)

Nice, i will add link to your project to my GH :) I see you solving +- same problem but a bit different way + my board have OLED to show the status and also that you supporting work on battery and i was not doing that. Another different i f

Thank you! I was thinking about it - as clocks and controller are indoor it is unlikely that there would be stable GPS signal, external antenna may be needed. Another option is to add DCF-77 receiver, this one could be used in most of the E
