How to make a primitive Silicon carbide LED – or not. Another failure.
“continue reading” for photos and details of how it should go.

This was supposed to work. A “cats whisker” fine wire touches a Silicon carbide crystal and with the negative electrode and about 12 volts you can at times see a yellow light which is a LED.

This however is not an LED but a simple heating of a semiconductor at a point contact.

Just to show there is power to make sparks and heat things.
