donbenjy Posted April 21, 2005 Report Share Posted April 21, 2005 hey, this friend of mine came up with the idea of getting some thermochromic film and making a scratchplate that shows up heat with colours, so say a hand print or whatever...but THEN he decided he wanted a logo on it to stay permanently and wanted to use nicronium wire which heats up (and resists 1 ohm per cm) and wanted to know how to do it...actually he was telling me the idea and i pointed out that having high resistance wire in a guitar circuit is a silly idea! he doesn't know alot about guitar circuits but hes good at electronics and thoguht the gutiar draws power fromt he amp so coudl be powered by that. i dont think enough current would be in the gutiar circuits to heat it up anyway and if it did it'd take the tone so we thought a 9V battery, resistor and the nicronium wire as a totally free-styanding circuit? i suggested using a stereo jack for on/off but he said no cos he wanted to show it off withotu needing a lead hes asked me 2 help out so i was gonna ask...has anyone used nicronium wire before? how hot does it get? dont wanna fry the circuits or melt the scratchplate i also thought of putting a variable resistor in too (it doesn't need a pot does it?) to control the intensity of the heat/logo. I realise this is very much a trial and error project as i have no idea what values of resistor to use, but its not a complex circuit so should be easy enough no idea what guitar im doing this to, but i was thinking if its a strat copy or similar controls rewiring to a master tone and using a push/pull pot for on off and the intensity of the heat in the replacement tone control hole?
