reducing the size of the inductor to 270 microHenrys will give 10 milliamperes.ģ. BP3125 Solar Panel Datasheet PDF - 125 watt Solar Panel, BP3125 datasheet, BP3125 pdf, pinout, data, circuit, ic, manual, substitute, schematic, equivalent. The current is limited by the L1 inductor, 330 microHenrys will allow 8 milliamperes to go into the LED. It detects when the solar cell is in the dark, and starts up the circuit inside that boosts the 1.2 volts from the battery to over 3 volts, and sends that to the LED. Datasheet: HACKING ELECTRONICS MEGA KIT We have expanded the original Hacking Electronics Starter Kit to produce the Hacking Electronics Mega Kit. It charges the 1.2 volt battery during the day, using power from the 2.5 volt solar cell. So now Im going to put together four solar cells, four AAA-batteries and one 5252F (I have three ICs as spare parts). So I bought 4 off cheapest possible solar garden lamps with rechargeable batteries. The 5252F integrated circuit does several things. Enjoy I have operated the circuit with 2½-9V, but maybe ca 5V is the best. 5252F using patented technology, LED Undervoltage shutdown makes no blinking LED lights. Can be only one external inductor Composition of solar lighting devices. I'm not sure why but I guess it's for a good reason. It is driven by a switching circuit, Optical switch circuit, over discharge protection circuit, the internal integration of Short Based diodes and other circuit. There's so many great laptop battery hacking content on the internet yet so little love goes to the BQ8050 fuel gauge IC. Still has useful circuit diagrams.5252F is a solar LED lighting fixtures for ASIC design.

5252F Datasheet – QX5252, Solar LED Driver Transistor IC.

You read the value from the color bands the same way as a resistor. The inductor looks like a resistor with a green (or anything other than tan) background.

you can swap inductors to get brighter or dimmer lights, making the battery last shorter or longer.

Keep cadmium out of the landfill by turning the cells in for recycling. Hello Swagatam Your site is of great help.

NiCads are used over NiMH in the cheap ones because they can accept twice the unregulated current as a NiMH cell. The label will not inform regarding its polarity, you may have to refer to its datasheet online to learn the details.

Speci cations subject to change without notice. Mine ran for a good week or so on the "dead" battery out of my Logtech mouse. IPT 2 Current-to-Pressure (I/P) Transmitter Figure 2. If you open them up and put in a "dead" (< 1v.) Alkaline cell, it will act like a "joule thief" circuit and suck the last bit of power out.

The really cheap ones usually have a AAA NiCad battery (or smaller) and no over-discharge protection, so there is absolutely nothing keeping the battery from being run down to zero every night.

The better lights would use Li-ion cells and discharge protection.

Here's a chart of the many variants including the properties.

A good keyword for the ASIC (application-specific integrated circuit) in solar garden lights is YX8018 I recall about a dozen youtube videos about the guts of a garden light.

Be forewarned, these probably won't be much use to anyone who doesn't know what end of a soldering iron to hold. Since we're on the topic of solar garden lights, I'll do a short little link dump.

It's also not lost on me that the people who know how to solder in a switch probably already have multiple flashlights in their EDC. But I suppose as long as you could keep a charge on your phone you could use that for a short trip to the WC.

I think it would be a more refined to add a switch, so you could turn the light off when you wanted to sleep yet still have some juice left if you needed to go to the bathroom. When the remnants of a hurricane came through my area and knocked my power out for a week, my neighbors trick was to bring his solar lights in at dusk.
