Introduction: Diy the Best Sunjar in Www.instructables.com :-)

It is very easy and cheap to diy a sunjar !My circuit can test the sunshine and the leds turn on only at night and turn off while the sun rise again:)

Step 1: The Circuit Programme

The units can easilly got by electronic pcb junks!

Step 2: Assembling

Now let us see how to make it by one wire one pin,and one wire one pin :)

Step 3: Just Have Fun From Your Sun Jar!

Collect the sunshine and keep it until night to use.

    your doing it again efan over complacating when this will do the same job

    my panels give out 2.5 to 3 volt at 20ma
    what i have just found is 2 in series wont run this circuit with the components i am using diffent pnp transitor and 1k res insted of 5k

    but if i get another to cells wire them up in series and parallel so i get 5-6volts but 40ma the unit works correctly

    you know it might be worth compareing them both see which one is more effecient

    yeah it is a little simpler just messing with the jt side seeing how many leds i can get working

    Yes. very clever design but i still want a simple anti-over-charge circuit.

    a Zener diode would also stop the over charge

    How about this one? but i think it could more simpler.

    i myself would find out what the trickle charge limit is and have a wind turbine run at that and maybe solar to charge it faster during the day as long as these dont go above what you use they wont be any problems
