“In Rod We Trust”
Mentally noted for doomsday, thank you very much.
Don´t try this at home. ;D
This takes me back to my schooldays, and making a model carbon arc searchlight with 2mm clutch pencil leads. Got it to work fine, using a model train power supply, but didn’t realise just how much heat came out: result, one melted plastic reflector.
On a practical note, the same type of controller can be used to power a hot wire cutter for shaping foam plastics. just google up ‘hot wire cutter’ for loads of ideas.
That’s how we cut the cores for model aircraft wings 
This is cool! ;D Thanks!
I´ll try that on SMD´s!!!
