Laser-receiver circuits must bias their avalanche photodiodes (APD) to achieve optimal gain. Unfortunately, an APD's gain depends on the operating temperature. The circuit controls the operating voltage of an APD over a large temperature range to maintain the gain...

Another version of the 1W VHF amplifier for the FM transceiver is presented. It is essentially the same version since achieving 1W output power has not yet been realized. Recent tests were conducted using a 2N2553 and a 2N2866...

The final step involves connecting the IR LEDs, resistors, and IR receivers to the Arduino. Begin by connecting the +5V pins of the IR receivers (the right pin when facing the receiver) with red wires directly to the +5V...

The water sensor circuit utilizes a 555 timer configuration along with standard electronic components. It consists of two metal electrodes positioned closely enough that a drop of water can create a conductive bridge between them. In cases where the...

This circuit is primarily designed to provide a microphone input for standard home stereo amplifiers. Utilizing a battery supply effectively eliminates the risk of low-frequency hum interference from mains power, simplifying the connection to the amplifier by removing the...
