"Little Torquey" High Frequency Pulse Energizer

thingiverse

Little Torquey is the same concept as Thingiverse's 2789344 but it's significantly smaller at 2.5 inches in diameter and 2.5 inches long. The wiring concept should be the same as shown here: https://1drv.ms/f/s!Apbifed6cvBmbjLYdzp4fQzMWGA. You can use 28 - 36 AWG magnet wire with this energizer, allowing you to use smaller batteries if desired. Several methods are available for pulsing this device, and I prefer the simple one-transistor Bedini SSG circuit. Parts needed include #6 - 32 X 3/8 inch brass or stainless steel bolts at all locations. Magnets should be 1 inch x 1/4 inch x 1/8 inch; you can find them here: http://www.magnet4less.com/product_info.php?cPath=1_5&products_id=34. A shaft of 3 to 4 inches is sufficient, available at https://www.servocity.com/0-125-1-8-stainless-steel-precision-shafting. Bearings can be ceramic or chrome plated steel; I recommend http://www.vxb.com/SR2ZZ-Ceramic-Si3N4-ABEC-5-1-8-x3-8-x5-32-inch-p/kit8288.htm for the best performance. Magnet wire should be between 28 - 36 AWG. Printer settings include printing with PLA at .2mm layers, 1.2mm wall thickness, and .8mm top and bottom layers. Support is not necessary with this design, but you can print it at 200% to double the size, which will also double the magnet and bolt sizes. Disclaimer: Build and experiment at your own risk. Catastrophic failure of parts spinning at high speed can cause damage to property, injury, or even death. There's an electrical function with this experimental device; don't attempt it without experience working with electricity, and avoid operating near equipment sensitive to electromagnetic frequencies.
