Hi All,

I have made my version of the Lasersaber Joule Ringer version 3.

I use an air core (see image for plastic bobbin size) coil in my design.
The oscillator runs at a center frequency of 167KHz. I light up a 12 Volt
1,8 Watt LED bulb (real Watt used if run from 12 Volt DC) and the LED
bulb is light at full brightness. I get a little over 13 VAC out with the LED
bulb as a load. My circuit runs from two AA batteries in series.

Added: The transistor and coils stays cool when running, but the circuit uses
too much current from the batteries, so the batteries get hot (approx. 40 degrees Celsius)
when running. So I need to see if there is a possibility to reduce the input current usage.

Added: I have tested the circuit on one AA battery. The circuit did use 0,5 Ampere and the
output was 11,7 VAC with the LED bulb as a load.

Added: I have tested the circuit on one AA battery. The circuit did use 0,5 Ampere and the
output was 11,7 VAC with the LED bulb as a load.

Groundloop.

The important thing in this circuit is the "electromagnetic flux" in the coil:

When using a big Ferrite core, a high "electromagnetic flux" with a relative small number of wire turns can be reached, which translates into a high Wattage of the lamps which can be lit to full brightness. Therefore we see people light incandescent lamps which need 20 to 40 Watts with big Ferrite cores.

Air cores have in theory no saturation (in contrast to Ferrite, therefore size matters when using Ferrite cores), but one needs a very high number of wire turns to achieve a high "electromagnetic flux".

Groundloop's air core needs at least 5000 to 10.000 turns for the secondary and 500 to 1000 turns for the primary to get what he expects.

With an air core geometry becomes a factor. To achieve a high electromagnetic flux, one needs to put many turns of wire in a small space. That translates into "thin wire", which has a practical limit.


Limiting the current draw of the circuit:

To limit the current draw a resistor is needed between secondary and base (e.g. try a variable 1 K resistor). But of course, when limiting the current draw less current will be available to light a lamp. When trying to light a 10 Watt lamp to full brightness at least 10 Watt have to flow into the circuit.

Many lamps (e.g. LED lamps) look fairly bright when feeding less than the specified Wattage into them. And in some applications the limited light output might be sufficient.

Greetings, Conrad

Here is a very simple 120VAC LED Bulb inverter using Lasersabor’s Joule Ringer 3.0 Circuit.   I used a RS (Radio Shack) 12V center tap transformer for the 6VDC and 12VDC tests and a 9VDC transformer liberated from a wall wart power supply.  Power from 12V 5Ah AGM Battery.  Results posted using a 7.5watt Utilitech LED 120VAC Bulb
-   6VDC connection ~ 830 mA = 9.96watt, Bulb extremely bright.
-   9VDC connection ~ 350 mA = 4.2watt, Very nice light output.
-   12VDC connection ~ 25 mA = 0.3watt, Very dim light output.

Using LOA 1.2watt LED 120VAC Fan Bulb
-   6VDC Connection ~ 1.4watt – extremely bright.
-   2 bulbs ~ 1.45watt – extremely bright.

Transistor runs cool on all tests conducted.  I will video and get some LUX readings this weekend and post.

Thanks,
Brad S

I rearranged the components a little bit to make the circuit diagram easier to read. Hope this helps replication.

  Here is a couple of pictures of my yoke core. It has 20 turns primary on one side of the yoke, and about 250 on the opposite side of the yoke of 28gauge. It's working pretty good considering that there is not a lot of turns on it. Transistor is a MJE (TIP) 3055. Running on a bad 12v battery. Transistor is stone cold,  like its not even being used.  NO HEAT, at all.  Showing a 25wtt Cfl, and the circuit will brightly light 65 watt Cfls, also, but not full on, yet.

Looks pretty good to me..... I'd mount the light fixture in the center of the yoke, that would look cool!

Meanwhile here's my latest neon rattler, using an inductor/transformer I pulled out of an old TV set. It has 9 turns on the primary. The secondaries are buried and are connected funny, I couldn't figure it out, so I just used a function generator to drive the primary and probed the secondary pins until I found the pair with the highest output voltage. I was able to light the NE-2 using only the output of the FG, once I found the 700kHz resonant frequency.  I'm getting very short spikes that go to 600 volts peak, from the AAA battery, which will run the NE-2 as long as the battery voltage is above 1.18 v.

I still haven't been able to get a CFL to light up using the AAA battery, though. Off to find more ferrite beads to play with now.

All,

I did add a germanium diode as shown in the drawing. I also added a small bias
current to the base of the resistor. Put a LED there also so that I got a nice ON indicator.

Adding the diode did lower the current usage from the batteries a little bit. The circuit
still maintain full brightness on my 12 Volt LED bulb.

Joule Rattler powers a Ring Oscillator of NE-2s.

Schematic for the ring oscillator below. You can extend to any odd number of stages. Flash rate is set by voltage and by the RC constant.

Thats awesome guys . Nice Mods to a cool circuit . I have to yake it easy going to hospital for a while but i will be back some time . I still have a lot to do yet.


Tk . that circuit reminds me of something a guy gave me when i was 12 . It was a dark green rectangle wax battery from the military / He was a Navy radio guy and built it for me . It had a tube socket on it with a plug in circuit like yours with a blinking neon lamp . It blinked for years and years off that wax battery . Good memories.

TK,

That was a really nice oscillator. :-)

Can't stop watching the blinking lights......................  :-)

All,

I have now tested this circuit variant. The circuit is designed to not waste any power.
The base current is also going through the primary coil. The negative spikes from
the high turn coil is channeled back to the minus rail through the Germanium diode.
The circuit overall current usage has gone down compared to the former circuit.
I also noted that the best input voltage for this new circuit is approx. 1,5 Volt.

EDIT: I did a little drawing mistake in my circuit drawing. The bias is at the other side
of the high coil as shown in this corrected drawing.

GL.

  Tinselkoala, Gadgetmall, and All:
   You suggested that I mount the Cfl (65 watt) inside of the ferrite yoke, well, here it is:

@Groundloop: outstanding... the NTE109 is the germanium diode.... equivalent to 1n60, a little higher voltage than the venerable 1n34 of crystal set fame, right? Why did you choose germanium here, I am curious.  I think in motor pulse speed controllers a Schottky diode is used in the corresponding position.... 


@NickZ: Wowsers!! That is amazing, I didn't know it was so big....  very classy! 
I still can't get my CFL to light with both wires connected... it lights about half-way brilliance with only one wire, though.....


And I've made another video of the Joule Rattler running on 3 and 5 volts, charging an external capacitor while running the ring oscillator.... I'm exploring the high voltage capability, but I'm also able to run the ring oscillator for quite a while on two AAA batteries. And earlier today ..... a very weird thing happened to two D cells I was using to run it..... they started sizzling and leaking fluid bigtime but weren't even warm at all .......

TK,

I trying to figure out how low voltage I can run this circuit on and still light one single LED.

I'm using the NTE109 Germanium diode because I have a lot of them.
(Did make an error in the past when ordering, thought I clicked the 100 pcs. but did clik the 1000 pcs. :-)

I have tested this circuit to run and still light my normal green LED at a input
voltage of 0,35 Volt. But the circuit needs a voltage over 1 Volt to start oscillating.

I'm currently working on a new coil (smaller more compact = more turns for less copper used).

  Tinselkoala:
   You might want to try to change the polarity of both the primary as well as the secondary wire connections, as it can make all the difference. Mine would not even start until I changed the polarity.
I also have the same problem of not being able to connect the bulb back to the transistor, without it ringing, or not even starting.  But the way I have it now it does not ring at all, but I still need to put my hand on the bulb to get it to light more brightly. So, I'm still working on that.  Any ideas are welcome.
