Circuit designed around a single IC that controls both analog and digital sections to provide a simple yet versatile meter. Terminal strip input. power switch, selectable decimal point. Space for scal...

Make this general design 3½ digit LED panel meter into your own voltage or current meter. Or customize it to measure input from a transducer. Full details given in the documentation. Separate display ...

A double-sided board designed to eventually replace Kits 2 and 34.

This kit is the hardware ‘platform’ that is the basis for a number of different timing modules. The hardware is the same for each kit -- the only change is the firmware programmed into the microcontro...

Uses an Atmel micro-controller. The first in a series of counters using µC's. This kits clearly shows how µCs can more than replace a host of ordinary logic IC's. This is a single-sided PCB that will ...

Circuit designed around a single Harris ICL7225 IC that contains digital and LCD driver sections to provide a simple yet versatile general purpose counter. 5V TTL signal levels for input and control (...

This kit is a stand-alone frequency meter capable of measuring repetitive signals up to a frequency of 50MHZ. It has two frequency ranges (15 and 50 MHZ) as well as two sampling rates (0.1 and 1 secon...

A continuity tester is one of the most useful pieces of test equipment to have. It is used for testing the electrical continuity between two points. Our tester will "buzz" up to a specified resistance...

This kit uses a commercially available 3 ½ digit Digital Panel Meter (DPM) from C&C, model PM-128 to display the temperature reading from two separate sensors. A switch is used to select between t...
