Here is a simple but inexpensive inverter for using a small soldering iron (25W, 35W, etc) In the absence of mains supply. It uses eight transistors and a few resistors and capacitors. Transistors Q1 ...
The circuit is aimed to provide a method for receiving serial data on one pin and transmitting serial data on another with a modulation at the infrared detectors band pass frequency. A tiny 8-pin ...
