Semiconductor radioactivity detector
Robert Gawron has been working on a semiconductor radioactivity detector project: Currently I’m trying to make a working version of a radioactivity detector that uses semiconductor as a sensor. It’s a different approach than Geiger-Muller detectors, more complicated, but also...

Flex Sensor to bargraph monitor using PIC16F886
Tiny Bar-Graph display provide a Red color, bright, easy to read display which is proportional to the force applied on the FLEX sensor surface. This Bar-Graph has 20 segments in single color and display Force applied on FLEX sensor. The Barograph force monitor is based on PIC...

Low-cost current monitor tracks high dc currents
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...

Withings Body Cardio Teardown
Nick tipped us with his latest teardown of an advanced weighing scale. He writes: The Withings Body Cardio is the latest in the brand’s range of smart health-centered devices, and the second Withings product we’ve tackled in this series! It’s a smart scale with a pretty...

Temperature alarm for boiling milk
Domen Ipavec shares his temperature alarm for boiling milk. Temperature alarm uses an Atmel attiny841 microcontroller, DS18B20 high temperature waterproof temperature sensor from adafruit, 2x16 HD44780 LCD and a buzzer to do its job. Anyone who has ever boiled milk on the stove...

Capacitor self-diagnostics
Peter Demchenko discuss about a design idea on how to test capacitors in circuit. The electrolytic capacitor is far from being the most reliable electronic component. One of its failure modes – a gradual loss of capacity – can hardly be noticed until power supply malfunction...

12$ 30MHz signal generator using Arduino
A signal generator is an electronic device that generates electronic signals and waveforms. These electronic signals are either repeating or non-repeating as per the requirements and field of applications. It is generally used in designing, testing, troubleshooting and repairing...

Analog Capacitor ESR Tester
TallMan's lab @ runawaybrainz.blogspot.com build a nice looking and simple analog ESR capacitor meter based on a EEVBlog forum topic. I finally got round to making my capacitor ESR tester this week after finding a nice simple 5 transistor version by EEVBlog member Jay_Diddy_B....
