Battery tester A simple tester for AA type 1.25V and 1.5V batteries based on an LM3914 chip and a LED line.

Microprocessor LED clock with alarm This article describes how to build a clock using a popular Atmel 89C2051 microcontroller and some simple HC-TTL chips. The current time is displayed in a pseudo-analog way, using 4 seven-segment LED displays (hours and minutes) and 120 LEDs on the clock dial's perimeter (seconds). The alarm and time is set by 2 push-buttons built into the power supply. A simple program in '51 assembler manages all the clocks functions. A stable +5V/1A power source is also described.

• Thermometer with PIC16F84
• Experimental 12V/6A power supply
