Jam Jar Solar - DIY Solar Powered Outdoor Light
Convert an old jam jar into an outdoor solar powered night light!
This relatively simple DIY soldering kit has all the parts you need to make a bright solar-recharged night light.
We have designed this with hardware to fit nicely into a jam jar, but it could be used in other enclosures.
It is based on the QX5252 solar lamp integrated circuit, which takes care of charging a nickel metal hydride (NiMH) cell from a small solar panel. It also uses the solar panel output voltage to control when the light switches on. It is also a step-up converter to supply the correct current and voltage to the LEDs, so we can drive four white LEDs from just a single NiMH cell.
This is a relatively simple soldering kit with some hardware. It is suitable for beginners, which should take in the region of 1-2 hours to build.
Note: Jam jar not supplied!
Full design files are available here. The PCB was designed in KiCAD and the hardware in Inkscape.
