The folks ofArcAttack — a crazy group of performing artist who apply singing tesla roll to create unbelievable melodies — have build up a lightning - proof guitar for a functioning on America ’s Got Talent . They ’ve decide to state us how they constructed the legal document and how it work :

The fret board is 72 optically isolate switches . The swither display board , rather of fret has 6 brass contacts per fret . When the string is pushed down to the striking , it makes a connectedness .
From there the signal is optically isolated , to protect from EMF and institutionalize to a micro controller that s only job is to priority encode the fretboard , and keep tabs on which drawstring is push down to each fret .
So precedency encryption signify this basically : if you are playing the 6th string on the 12th fret , then the computer disregard if say the 11th and tenth frets are press on that string also , since the 12th lather needs to take precedence – just like a real guitar .
Now there is a second computer that is located on top of the fret board underneath the metallic element loge . This computer detects when the strings are strummed , and is also updated by the first computer whenever the fretboard changes DoS .
It is also the second information processing system ’s duty to process the fretboard and strumming data , and output midi messages accordingly . The midi signal is converted to a fibre optic light pulse , and is sent down as ocular information to the Tesla coil ’s master computing machine , which is responsible for processing the midi commands and output a pulse rate intonation signal to control the slant of the tesla coils .
The final stage result : The most stone and roll display ever . substantial lightning guitar , while the player plays the guitar , he is being struck by lightning that bring on the strain that he is playing .

At this point , most enlightened masses think we were just hold it as a prop , or deeming it imitation . Hehe . I guess I ’m flattered . NOPE . It was real . Most everyone else just does n’t get it .
The intact time that Tony ( the first faraday suit performer ) was in the spark , he was in full command of the tesla coil melody until he walked out of the spark , at which point our restraint computer took over and toy the solo of the vocal . It ’s rather hard to make for the guitar with mountain chain mail gloves on , so we had to keep it fairly simple for him .
The guitar is protected from the lightning via optically coupled switches , and exceptionally cagey shielding .
The creation of this instrument sound as half-baked and take as an ArcAttack performance , but you may actually see one of those performances yourself on the September 8 August 24 public exposure of America ’s Got Talent . At that clip you could also choose to support the group with ballot if you enjoy what you see — but please do keep thevoting rulesin mind .
