Prewar tv set Marconi 707 from 1938 with rewound LOPT The bad line output transformer of the prewar tv set Marconi 707 was rewound by Ed Dinning. Now the tv set has full line width and correct linearity. A BBC broadcast from 1936 is on display and a scene from the end of 405 line tv transmission in Britain in 1985, displaying on a 1938 tv set.

Plasma Speaker / Tweeter - Completed Working Setup The complete prototype circuit is shown here built on a single PCB. The reflector is made from PVC pipe with a rear mirror. EHT now slightly lower and the gap size has been reduced. Track is 'Hold Me Now' from the Thompson Twins - chosen purely for it's good dynamic range, vocals & clever percussion ! Let me know if would like to see & hear any particular song - see what I can do ;) Tags: Plasma Speaker Tweeter Singing Arc Tesla High Voltage Hi-Fi Electronics Audio EHT Flyback Transformer LOPT |

Plasma Speaker / Singing Arc - Early Modulated Prototype Please watch my other videos of this... Here is an early prototype of a powerful plasma arc speaker / tweeter. This has now been superseeded by an efficient microcontroller based system. Supply voltage in this design is 50V DC - HV output is approx 60KV - Song playing is Alice Deejay's 'Better Off Alone' - Be sure to subscribe, to recieve future video updates on this project & others :) Tags: Plasma Speaker Tweeter Singing Arc Tesla High Voltage Hi-Fi Electronics Audio EHT Flyback Transformer LOPT |

Plasma Speaker - DREAM THEATER / LTE - Acid Rain Here's an extract from LTE / Dream Theater's Acid Rain. The arc is powered up slowly, to demonstrate that it is indeed the plasma producing the music you can hear. A few of you had mentioned you might like to hear a DT / LTE track - here it is :) Tags: Plasma Speaker Tweeter Singing Arc Tesla High Voltage Hi-Fi Electronics Audio EHT Flyback Transformer LOPT |

Audio Modulated Plasma Mini Jacob's Ladder I scavenged a couple of wire coathangers and a length of wood and connected it up to the plasma driver. Fairly crude setup, but it does look cool in the dark :) The sound quality is not as good as it could be, due to the poor finish on the vertical electrodes of the ladder. This causes unwanted audio distortion, as the plasma arc is pulled upwards. Stainless or hard chrome-plated steel would be ideal. Notice the 'Gabriel Electrode' & high voltage resistor at the bottom of the ladder, to aid starting.

Singing musical arc / plasma flyback Easy to build singing arc. Use any flyback driver running at high frequency and a 1 watt amplifier and transistor to switch the DC input and the rate of the music. Here we have 12 volts at 4 amps, so the arc is inly 1/2 inch or 1 cm. The music isn't too loud, but is clear with no power supply or HV flyback noise. The music is the Beach Boys because I'm old and like the West coast sound rather than the Mersey sound of the 60s... Even if I am English. Cheers.

simple feedback driver for flyback transformer Here's my new driver for my FBT which uses feedback from the transformer. I hope to make an audio-modulated driver soon. :-) The circuit came from http://www.powerlabs.org/flybackdriver.htm and/or http://www.sixmhz.com/flyback.html . UPDATE (Mar. 9th, 2008; please read everything): Sorry, I forgot to tell how to 'find' the coils needed for this circuit. This circuit requires 3 coils: a primary coil ('input'), a secondary coil (high voltage 'output'), and a feedback coil (used in finding an appropriate operating frequency). I'm pretty sure that all of the pins on the outside of a FBT are connected to sets of coils inside it. In order to find the coils needed for this circuit, check all of the combinations of pins to see if they conduct a current (have a coil between them) - like this: http://www.geocities.com/drewh0208/finding_coils_in_a_FBT.GIF Once you have a pretty good idea about which pins are connected, experiment with different coil arrangements to see which works best (usually when the FBT makes the loudest pitch). If you find a pin that isn't connected to any of the other pins, then, while the driver is running (with the primary and feedback coils hooked up to the drive circuit), CAUTIOUSLY bring the obvious high voltage output terminal (a heavily insulated wire sticking out of the unit) near that isolated pin and see if any sparks jump between the two. Make sure that the HV output doesn't arc to any of the other pins, especially the ones connected directly to the circuit, or else you could short out a whole lot of other things. I haven't had any personal experience with FBT's with two heavily insulated wires coming out of it, but my first guess is that those two wires are both of the ends of the HV output and would arc to each other. An alternative to finding coils (for the primary and feedback coils) inside the FBT is to wind your own coils on the exposed part of the ferrite core. Check out this site for an example of how many turns to wind: http://www.powerlabs.org/flybackdriver.htm Sometimes winding your own coils will produce a higher voltage than using the built-in ones; it depends on the FBT, what kind of power you're using, your driver, etc...
