Microcontroller-Based Duodecimal Clock Project

The seven-segment LED displays were mounted on the foil side of a single-sided circuit board. I used single-row, in-line sockets to facilitate soldering. The sockets also elevated the displays above the circuit board and the SMT resistors placed beneath the displays.

Programmers and embedded circuit designers know that decimal is not the preferred number system for digital devices. Binary, octal, and hexadecimal numbers rule the day, so they’re comfortable using strange number systems. Clocks are essentially duodecimal, or base-12, devices. Devlin Gualtieri designed a … Continue reading

Tips for Measuring Small Currents

Figure 1: The current sources: ideal (a), semiconductor (b), and resistive (c)

Most inexpensive hand-held multimeters have measurement ranges from several amps to single-digit milliamps. While generally handy, such meters are insufficient for sensitive current measurements. There is a solution though. With the following project, you can extend the current measurement range from milliamps down into the nanoamp and picoamp … Continue reading
