The hot melt glue that covers the circuit serves multiple purposes: It helps to keep the temperature even among the three transistors (to minimize thermal drift), it protects the components from physical damage, and it holds the battery holder on the board. As I used this probe last nigh to determine if a 384 MHz

The ATmega8 microcontroller-based Low-Cost Telemetry Device (LTD) is an efficient telemetry keyer. The LTD measures the voltage levels of up to four analog channels via its on-chip 10-bit ADC, converts the measurements to numbers, and then sends the data in Morse code to an external transmitter and to an attached RS-232 terminal. It can be

Animator is a device, rather 5 × 16 matrix LED , which are used to display simple animation. Initially, the device serves to something completely different and it was controlled directly from the parallel port for the program is written in Pascal. The idea has proved to be a bit pointless because the program does not provide an even
