Tesla coil - From Wikipedia, the free encyclopedia
A Tesla coil is a type of resonant transformer circuit invented by Nikola Tesla around 1891. It is used to produce high voltage, low current, high frequency alternating current electricity. Tesla coils produce higher current than the other source of high voltage discharges, electrostatic machines. Tesla experimented with a number of different configurations and they consist of two, or sometimes three, coupled resonant electric circuits. Tesla used these coils to conduct innovative experiments in electrical lighting, phosphorescence, x-ray generation, high frequency alternating current phenomena, electrotherapy, and the transmission of electrical energy without wires. Tesla coil circuits were used commercially in sparkgap radio transmitters for wireless telegraphy until the 1920s, and in pseudomedical equipment such as electrotherapy and violet ray devices. Today their main use is for entertainment and educational displays.
Adafruit's embroidered badges are manufactured in partnership with AMBRO Manufacturing located in NJ, USA. AMBRO is a family owned and operated business since 1990 that celebrates open-source with Adafruit Industries. You can meet their team here. AMBRO uses non-toxic soy based, water soluble and environmentally friendly printing supplies, threads and more when possible. AMBRO has over 250 solar panels that generate 50,000 Kilowatt hours per year. Their equipment runs solar powered, so the wonderful things AMBRO and Adafruit have worked together on are made with the sun! AMBRO Manufacturing was recognized by Impressions Magazine, a leading trade publication in the garment printing and embroidery business, who published an article highlighting AMBRO and their commitment to their environmentally focused manufacturing practices. Adafruit knows you have a lot of choices as to where you spend your money and time, we hope our open-source values, commitment to green technologies and partners helps make the decision easier and fun!
