Joule Thief

Hey Bill . WE can now get close to 60 watts from a jt . This means lighting clfs full bright , next step is running inductive loads like tv's ,radios , chargers , small stuff for now but indeed a big leap . WE fry leds for supper now and it's going way past those little jts from the early days . the secret is large wire  primary's and big power transistors . Fun it is .

Here is my 6 inch setup incased with an aa battery (2 parallel) providing a fixture ready to mount in my shop . Will be charging it via a 6 volt panel with small LM regulator transistor  set to 2 volts . She will run day and night .

Sorry Gdgetmall,
I am a little bit confused, is this the circuit of Lasersaber 3.0 or the microinverter you modified and post in the last page?
I read that you modified the coil to double primaries, but you did not explain if you are using the push-pull inverter mode to achieve the latest results.
Thanks for the clarification.

You mean solar panel,YES, that would be fantastic
I'd try this experiment myself using very big panels and Exon lights, the results were not good,
at best the battery took longer to run down then it would have done if there were no solar panels

I hope you have better luck than me.
All the best

OK . 6 volt Solar panel keeps My new LifePo pack charged(replaced the AA's with a smaller more powerfull LifePo pack) and runs 24/7 led house bulbs ! I have free energy lights in my shop outside now ..

I am almost finished with Lasersabers Soln1 project . My 20watt panels has built in inverter for house current to 175 watts . Built in perpetual light for easy location in the dark .built in led volts meter ,built in Ls3 module and runs from 3.2 volts and powers any bulb all night . Built in radio , and more !! . I will show it when finished and am selling it on ebay .. It is the Backpackers or Doomsday preppers  best friend .

I just completed a 4th ls3 using junk . I found some ferrite barrel connectors and glued two together making a three inch "tube rod" I then glued these plastic medicine caps on the edges . I then wrapped 5 layers of #26 on and not to neat either .(about 100feet) It overlaps in several places more than 3 or 4 turns but i just kept winding until i was tired ') I then black taped that wad and wound 1 and a half layers of black solid strand bell wire you get from radio shack . About 7 or 8 feet . . I used a Cheap Tip3055 and it runs Led bulbs 220 volts or Incandescent bulbs great off just 2.5 volts and really good on 5 or 6 volts . The transistor runs Ambient room temp (cold)

I have yet to make one NOT Work . The key is lots of wire ...

In the picture is the third barrel next to a penny to show what they are and the size . As you can see that Globe light is a 220 volt led bulb i bought for a dollar off ebay . It is dim on normal 110 volts but it lights up bright on My new ls3 Junkyard setup  off 2.5 volts.The other bulb is of coarse a filment 8 watt aquarium light bulb. it is full bright on 6 volts input and this little unit runs any unmodified cfl full on .

also a picture of the new lifepo4 batteries . 3.2 volts @20 ah .. I have 4 in my 20watt panel .They require a Power conditioning circuit(PCM) which keeps the batteries from over charging and undercharging and balanced from the 1.16 amp Solar panel . The panel contains a yellow led visual indications of exact voltage . Also has two usb charging ports for ipads,cell phones and any usb charged device . It also has two 120 volt recepticals one from the inverter and one from the LS3 . One usb port and one 120 outlet is powered only by one of these batteries . 

Video coming of How to build as soon as some parts arrive . This unit comes with a keyed switch and all fused and led indicators . also two three way switches control the inverter ,ls3 ,Usb regulator and an additional Jt ..It is a fun project but expensive and i need to sell it .

Wow... those LiPos look really cool, and dangerous too..... nice stuff you've got there.

Meanwhile I've been having fun too. I took an inductor, 10 mH, from an old TV and wound a primary on top of it, and now I light a NE-2 on as little as 1.0 volt from a AAA battery. The scope indicates spikes of over 150 volts on the output even with the neon connected.

This one has around 300 or more turns on the original winding, and then I put around 30 turns of #22 on top of it, over a layer of cloth tape. Using LaserSaber's circuit with 330R in the base resistor. The heat sink on the 3055 is just for show.
