hacks like this...

j4cbo needed a way to avoid "boom!" if he wired up this transformer incorrectly, and he also needed a way to power it on and be able to depower it in a hurry if things went wrong. The toaster killed two birds with one stone; it limited the current, and not only that, but it has a handy on/off switch (one that releases bread when you turn it off!).

As an added bonus, it has a control for how light or dark you would like your circuit.
