Help Making a Toaster Lamp
I need some help making a toaster lamp.
Now I know what youâre thinking, â I always wanted to make a toaster lamp!â. Well nowâs your chance to help.
In its simplest form a toaster lamp would be a base of a toaster with the top of a table lamp. The lamp operates like a normal lamp by pulling the string or turning the switch. The electronics in the toaster would be disabled or removed for safety reasons. This would be the simplest model.
But I would like to build a model where you press the toaster lever down and the lamp lights up. To turn the light off you press the cancel button or press the toaster lever up. Furthermore the light-dark setting on the toaster would act as a dimmer switch for the lamp. The toaster heating elements would be disabled for safety reasons.
Now a basic toaster works like this:
When you push down on the handle, a plastic bar presses against the contacts and applies power to the circuit board. 120-volt power runs directly through the contacts to the nichrome wires to start toasting the bread. A simple circuit made up of transistors, resistors and capacitors turns on and supplies power to an electromagnet. The electromagnet attracts the piece of metal on the handle, holding the bread in the toaster. The simple circuit acts as a timer. A capacitor charges through a resistor, and when it reaches a certain voltage it cuts off the power to the electromagnet. The spring immediately pulls the two slices of bread up. In the process, the plastic bar rises and cuts off power to the toaster.
Some of the problems Iâm facing are the voltage to the electromagnet and PC board is about 12 volts. If you bypass the nichrome wires that would send 120 volts to the PC board which would toast it. So we need a way to do that.
Another problem is we donât want the capacitor to cut off power to the electromagnet, that would shut off the light. We could not charge the capacitor by putting a larger resistor before it, Iâm not sure how to do this.
The ideal solution would be to gut the toasters electronics, replace it with a circuit that does what I want, and the toaster just becomes a faÃ§ade.
Now that Iâve outlined what I want to do are there any electronics wizards out there who can design me a circuit to do this?
