David Johnson-Davies designed a minimalist ATtiny85-based watch using 12 LEDs, arranged like a clock face, to show the time in analogue-style. He writes: To show the time you press the button on the watch face, and the time is then displayed for four seconds. It lights one LED to...

The PCB Rax is an easy to use, versatile printed circuit board holder for repair, prototyping , and assembly that can hold nearly any shape of circuit board. Check the details on the link below. Not all circuit boards are rectangular. PCB Rax was designed to hold all kinds of...

Susanne Nell @ edn.com has a design idea on how to measure high dc currents. To measure high levels of direct current for overload detection and protection, designers frequently use either a current-shunt resistor or a toroidal core and Hall-effect magnetic-field sensor. Both methods...

Online circuit simulators are getting more popular day by day. Electronics hobbyists, as well as professionals, use circuit simulators often to design and check circuit diagrams. The best thing about online simulator is, you don't have to install anything at all on your PC or laptop....

M0xpd documented his experience building DuWayne’s Scalar Network Analyzer Jr: DuWayne’s project uses an AD9850 in one of our familiar modules to generate RF, under the control of an Arduino NANO. You can read on DuWayne’s blog how the SNA Jr is the descendant of earlier...
