Re: Arduino LED "Roto" Clock and other Arduino Projects

This clock accuracy, 2 ppm, is pretty amazing at this low cost $2.50. I presumed integrating a crystal had a substantial cost. Not so, this looks like magic to me. Other IC you might be interested in. Audio player. MP3 decoder chip. http://www.flyrontech.com/eproducts/164.html MP3 modules. http://ww...

The DS3231 TCXO has a 0-40°C time base error of only ±2 ppm vs the almost 60 ppm error of the DS1307's external crystal.

I think I paid about $2.50 US for the DS3231 module.
Is the DS3231 a module or an IC ?
Is the Xtal integrated inside the IC ?

Who knows ?

In France, it is forbidden by law to collect statistics on race, ethnicity or religion.

Re: The Great Replacement

Figures published few days ago by the government seemingly happy to claim to do better than before. ROFL.

In France over 2019. Edited ( typo 2919 ).

31200 illegals regularized.
18900 illegals expelled.

Who knows how many more are who knows where.

Re: Things that go beep......

Yes, this is the best I got to running with 12V battery. I can use one in my camping car. For more power UPS run on 24V or 48V. 24V,48V cannot be done simply with 12V car batteries in serie, because of battery balancing, but may be this is no big deal. There exist modules inside Li Ion battery packs...

My UPS are all 12V-powered and I have 6 of them.
I have thought about powering them from one of the cars if we had an extended outage and I couldn't run the generator for some reason.
How much AC power could you get running UPS from a car alternator?

Re: Things that go beep......

UPS is something I used to salvage too. Many go to the dump because of batteries that don't last and high cost of new batteries. A trick is to get models that run on 12V, then any car battery is good for it. A UPS is happy running that way, and this gives a fully charged battery ever ready. What kil...

Re: Things that go beep......

Things that glow... I had salvaged a bunch of security emergency exit lights from refuses. The idea was to make good NiCa battery packs from the good cells. When I trashed the left overs, all had been charged, I was sad to see long dying ones desperately glowing to stay alive. I had kept a few of th...
