The Café (There is no Topic)

I don't fancy being barbequed! (and I doubt I'd taste very nice, anyway!)  

As long as she's here I don't give a damn! Sky Blue Pink with Yellow dots? Mary suggests Sandy Grey Russet!

I have good news and bad news. The good is Mary and I are getting better, the bad is we've had Covid. I don't ever remember feeling so rough. "death where is thy sting?" doesn't even come close.

 I wouldn't give it to my worst enemy. My Tenants kids had it, they weren't even in the same room but we had to repair 2 ceilings in the house and still got it.

One of the problems about being so isolated is we never get what's going around, we interface with very few people (one, and that's only once a week!)

That's the benefit of internet - only the computer gets viruses!

Here's something I found on another forum, that may be of interest to those of us who like 'playing' with electronics -

I've come across a novel but unusual boost switcher.  The Pololu range. TheU1V10F5 takes an input from 0.5V (actually I tested it to a tiny bit lower) up to 5V and it gives a 5V output. But  this is where things go differently. If you increase the input voltage above what it is supposed to deliver, the device drops into a linear regulator mode keeping Vout at 5V. MAximum input current (in switcher mode) is 1.2A so Iout is whatever it needs to be to achieve that.  Efficiency approaches 90% for Vin at 3V So ideal for generating a supply from a single NiMh or dry cell. Also useful for Li-ion except that in  that case you'd have to check for minimum discharge voltage as this would carry on until the point the cell is damaged by too low a terminal V.  They make other voltage ones too, 3.3v and adjustable. But the thing about this that's a bit weird.  They only seem to be available as modules, eg. from the Pi-Hut where I got mine.

 I've searched for the data sheet and they only ever show the ready built module, about10mm square, never details or specs on the raw device.
 

If anyone finds the forum  pages are acting up or running very slowly, I've reported it to Mikey admin. 
But as he only deals with problems in his spare time, don't expect a quick result.

One for those of us who like 'small' models! - - Tony klippy might have heard of this one?
