I reveal a secret the power company and phone company don’t want you to know about! Great for emergency power too!

This floppy disk burn through is another example of what a 140mW red (8X DVD burner) laser diode can do focused to a few mils at a close range. Measured for this test at 84mW @ 650nm. WEAR YOUR EYE PROTECTION!!! These things can blind you “BEFORE” you can blink at this power! or at [...]

triode is an electronic amplification device having three active electrodes. The term most commonly applies to a vacuum tube (or valve in British English) with three elements: the filament or cathode, the grid, and the plate or anode. The triode vacuum tube is often viewed as the first electrical amplification device, although the relay (which [...]

An operational amplifier, often called an op-amp , is a DC-coupled high-gain electronic voltage amplifier with differential inputs[1] and, usually, a single output. Typically the output of the op-amp is controlled either by negative feedback, which largely determines the magnitude of its output voltage gain, or by positive feedback, which facilitates regenerative gain and oscillation.
