What I have here is a prototype of the wonder toaster model 2. It is a fantastic piece of machinery, handcrafted with love by well cared-for Swiss midgets. It is a high powered model, drawing 12 amperes to deliver a hefty 1.44 kW to you bread for quick toasting.

It is currently not UL approved, but my company is in the process of pushing the papers.

What voltage have you that designed for? Resistance wire looks fairly thick. Or maybe it’s for high power ultra fast toast.

UL recognized? ;P
UL isn't a requirement, companies just do it for the cool shiny stickers...

Not sure how effective it'll be without an enclosure. Bahh, just crank up the power.

It's 20 something feet (9.8 ohms worth) of 18ga nichrome. Turns out I needed a little coil at the end to use up the extra wire.

Speaking of pop up mechanisms, I've always wanted a toaster that shoots toast 6 feet in the air...

On a carpet, no less. Cant wait to see the results... by the way these solder joints are silver or lead... i would put the whole thing on a pan of gas or acetone: the toasts will go up alright... Please post photos of the "first light"....
