A look inside a fairly common solar fence light.
150mah? Wow, that's insainly low capacity for an AA, in a world where 2200+ is the norm. As you said thoough, interestly honest, compared to the 15000mah ultrafire things you see on ebay/ali which are normally only about 1200mah in reality
You may also notice that the massive space for the solar panel is only populated by a few thin strips of trimmed cells, encapsulated to give the impression of a larger one. Each strip will be approx. 0.5V, quite a low current though. Strips are used, rather than a single larger cell to get the voltage up a bit to help charge the battery.
inductor? isnt that a resistor?
You seem to just love solar lights (especially poundland ones).
B&M bargain by any chance?Got several of them, some have 300mah and some have 150mah AA's
Got a few of these from the B&M shop or bum shop as i call it , These things dont seem too bad although i was tempted to try switch the led color for something else
I can't see clearly on the video but does this use the ANA608? If so, this circuit is extremely common in solar lamp circuits, it seems. We've bought certain products like this in the past and they've had similar circuits. http://www.flytron.com/electronic-parts/240-ana608-solar-charge-and-led-controller.html
Can you add the missing components on the board without knowing their values to work out what the other product line might be?
Hmmm, designed to run out of power just when you need the light most!
If they used slightly larger "panels" in there, then the 150mAh battery could be replaced with something of a decent capacity that doesn't die after half an hour's use… :P
Big Clive. Dave over at the eev blog did a battery test on mainstream batteries recently.(as part of the batteriser/recharge alkaline batteries for free nonsence (sarcasm included in here )) i would be interested in your results on the crappy green batteries. when you have the time. ta. J
JD1803 is typically the 4 pin chip used, in my experience
easiest teardown in history, I wonder the longetivity of that battery
+fredlllll – It's an axial inductor. Modern technology can be very deceiving.
Clive, I would like to request you make a video of all the tools you use in these videos. Because I like your screwdrivers, and also like your sidecutters. Thanks!
Clive, I want your beard.
