For some fun try setting up one of those RAM chips in a breadboard with inputs set up to disable the chip, then measure the power supplied to it. Last time I tried that it was under a microamp! Which is why a coin cell can keep the contents of the chip intact. The tricky part is making sure that none of the enable inputs are active when switching from main system power to backup and vice versa.
With the bent pins on your static RAM chips, if you can get the legs straight, mount them in machined pin DIL socket, then use the DIL socket pins to plug into your board.
That way you take ALL the strain of insertion and removal away from the IC.
Finally PostBag Time !
Bring back old LED and boost/buck converter postbag videos :), for some reason this is pleasure to watch
So much stuff today…
scary to have li-po batteries like that in box with out individual packing. one small components between contacts and boom,
you should've measured the accuracy of the battery voltage tester, this is useless otherwise imo
What a blast from the past! Your computer reminded me of how to boot the PDP8 when I was at the cutting edge of electronics!! But we had real core memory. Now that would be an exciting addition….
Didn't you notice the negative sign in the box on the bottom left of the case ??
Yay it's postba—- Oh it's finished!
I need to stop watching you on mail day I end up buying stuff ,Thanks😀
Those memory chips are recycled. The date codes are 1213 and 1426; different years. They're also different types, as signified by the 'L' at the end of the number on one of them. The pins were very likely bent even before the package was posted. And foam plastic for 'protection'??! Static damage is also a possibility.
I think when you are talking these model batteries that the "S" stands for "series". Packs are denoted as 1S, 2S, 3S, then 1S2P, 2S2P, 3S2P etc. The S means series and the "P" means parallel. A 3S2P battery has 6 cells.
yey… its post bag.
Hi Julian please take this as positive criticism, but the postbag was rather poor and weak in content. I struggled to watch it through my broken screen on my mobile only to find it lacked lustre. No offence intended.
