Lionel Acela at Westport, CT First Night The test track runs of my Acela were the lead-up to this New Year's Eve event in Westport, CT. (More) The test track runs of my Acela were the lead-up to this New Year's Eve event in Westport, CT. "First Night" in this town is a collection of family-friendly events, one of which is a public model train display presided over by "Dennis the Conductor" (also a friend of mine).
After hearing about last year's event, and the kinds of trains that prompted the most positive response (hint: New Haven wasn't recognized), I decided that an Amtrak Acela would garner a positive response due to its ultramodern appearance and that it also passes through Westport's Metro-North station.
While the Westport Public Library's folding tables were somewhat swaybacked to varying degrees (The Acela's couplers are very sensitive to irregularities in track elevation), we managed to iron out the gremlins enough to give the children and their parents a good show in the latter half of the three-hour display.
The first shot was taken during the show with the public in attendance (I couldn't move around as I was manning the transformer powering the Acela's loop, sounding the horn to warn curious children away as the train approached), and the second was taken after the display ended and there was room to follow the train around the loop.
Normally I am a staunch proponent of using an actual camcorder to film clips intended for YouTube, since most digital cameras up to fairly recently recorded choppy video and weak scratchy audio. I was suitably impressed that my new Canon Powershot Sx-100 proved able to record smooth 30FPS video and decent audio, which is why this pair of clips were deemed okay to place here (Most of the artifacts were the result of Windows Movie Maker, which I used to join the two M-JPG clips--the original is just as clear as if it came from a DV camcorder) (Less)
Arcing from toroidal transformer Schematic: http://img81.imageshack.us/img81/7995/toroidsparkercj5.jpg T300-52 iron powder toroid, (More) Schematic: http://img81.imageshack.us/img81/7995/toroidsparkercj5.jpg T300-52 iron powder toroid, wound with 50 turns #24 AWG closely together on the primary, and 600 turns of #30 AWG on secondary. Input is a 4.1 kHz square wave from an IRF740 MOSFET connected to ~12 Volt power supply, 50% duty cycle. It's a pulsed DC entering the primary. Since the square wave is DC during the mark phase, and DC goes easily through an inductor, there was quite a bit of current being sucked through even though no load was on the secondary. Nevertheless, as you can see, even with a 1:12 stepup ratio (as would be the case with a sinusoidal input), the square wave resulted in what looks like 3-5 kV from the secondary. With a real load (like a water cell) this would drastically drop, but interesting to see 12 volts turn into a several kilovolts with a mere 600 turns on an iron powder toroid. It's a flyback effect, but I'm not sure how this hand-wound toroid stacks up against a commercial flyback transformer. Once you have a higher voltage signal, then you'd probably need an impedance matching or bridging network between it and the water cell, or perhaps a pulse-forming network to sharpen the spikes and crack the water that way...
