Like many other engineers out there, I often find myself late at night browsing though electronic components catalogs, component distributors ,cheap gadgets sites , while compiling TODO lists , TOHACK lists ,TOBREAKOUT lists , TOEXPERIMENTWITH lists...
But alas, given the finite resources ( $$$ & Time) I'm unable to experiment with all of this stuff.
This is why I'm creating this series of posts containing Interesting stuff recently added to my TOEXPERIMENTWITH list so that other people might put them to good use =]
Today's list is.. well.. not a list.. it's a single item:
A Cheap UPS for your projects: These are meant to power CCTV cameras and related equipment. but you could use them to keep a micro-controlled project alive for week or even months if you use your sleep modes (or dedicated watchdog) wisely !
"9800mah" Found at Dealextreme for $42.5
"6800mAh" version Found at Ebay for $18$
"5800mAh" $15.77 - 22.68 at aliexpress.com
The quotes on the battery pack capacity reflect the fact that I don't trust these specifications until I test them myself... This shouldn't stop you from experimenting with them , just apply a good margin of error to your needs (consider them to be say.. 25-50% the rated capacity...still a reasonably good deal!)
That's it for today... see you again next time on
The Hackeneer's wishlist !
