Hi there!

First of all thank you for all your great vids.

I took several of these garden lights apart a few months ago and I wanted to add one of my super caps to the charging side but there only seems to be a voltage of .3 to .5 which seems to low to work with or have I missed something?. Do you have any suggestions as you said you were going to add a cap yourself. Did you have any luck?

If you just hook it up I think that you will find your multimeter is registering the massive spike of voltage. The capacitor will charge, make sure you use a diode to the positive side so you do not damage your Solar cell..

That thing supposedly available here in the Philippines, and Our government will purchase it and distribute it to many poor areas in this country that have no electricity yet.... that thing will help a lot to those little kids reading books at night using only a kerosene lamp .... In your country you just use it in your garden, maybe us here we can use it in our living room.... thank's a lot SIR KUBIKOP... keep uploading useful videos like this....

[kubikop]

Thanks, and I hope it helps you to not uses kerosene lamps as there is a risk of fire...

What you call "Joule thief", in this case is just a DC-DC converter, a very well known type of circuits. I think that the term "Joule thief" was used originally to refer a circuit that can get some usable energy from almost depleted batteries (it is a rudimentary steep-up DC-DC converter), so I think that we shouldn't use that term for everything that uses a coil and an oscillator. Anyway, I enjoy a lot your videos.

[kubikop]

Yeah, I know its just become a bit of a slang word I think. The circuits are good at squeezing the last drops out of what seem like dead batteries though.

Glad you like the videos too...

i got the same one from poundland..brilliant.

@Tubeglowfun yes you can add an UV led to an solar garden light,it won't be any problem :)

[web1bastler]

its an 1/3 AA batt

nice

[Tubeglowfun]

Nice video. I have a possible application if modding the circuit will work. Should I be able to swap the white led for a UV led without burning out the led or circuit? Maybe a bigger battery too. Voltages and currents seem similar on both white and UV leds. I need to make a bug attracting light that will mark the arrival of certain pests in my fruit trees. Modding a garden light might be just what I need.

we all need a Gold Tree* VS A "Money Tree" you can make some money off stuff you doing .. a Gold Tree will do ...Ppl are out of jobs so we are turning to cheaper ways

to save money it is 3:25 am power bill used to be $187 to $203 this time of year

now i use a long "mirror and your lights and it lite up yhr whole house

[Iman2Meet2Wheels1970]

Great video YOU NEED TO GET ALL OF US TOGETER IN ONEchatroom ok LOOK

you got something here open a chatroom in Buzzen chatroom soon so we all can put our tip /minds togther see what works best Huh

[Iman2Meet2Wheels1970]

can't get it to post TEST 1 23
