The voice unit (VU) meter is a device that displays a representation of the signal level in audio equipment. It is used in some consumer audio equipment for utilitarian purposes such as in recording devices or for aesthetics like playback devices. The original VU meter is a passive...

Atmel tinyAVR microcontrollers are optimized for applications that require performance, power efficiency and ease of use in a small package. All tinyAVR devices are based on the same architecture with other AVR devices. The integrated ADC, DAC, EEPROM memory and brown-out detector let you...

Ouija Board is a flat board marked with the letters of the alphabet, the numbers 0–9, the words "yes", "no", along with various symbols and graphics. It uses a small heart-shaped piece of wood or plastic called a planchette. Participants place their fingers on the planchette, and it is...

This project is an electronic dice. It consists of seven LEDs positioned like a dice which light up to show the number. The leds are controlled by a 74HC4017 decade counter IC. Of this IC six outputs are used to drive the LEDs and a seventh output is used to reset the counter. This...

Circuit Basics writes: In this video, I'll walk you through the steps of setting up a Raspberry Pi from the first boot up without a keyboard or monitor. This process requires only a PC or Mac, an ethernet cable, and access to a network router. How to Setup a Raspberry Pi Without a...

Linear Technology announces the LT6658, a precision voltage reference that incorporates two high current output buffers. The LT®6658 precision 2.5V dual output reference combines the performance of a low drift low noise reference and a linear regulator. Both outputs are ideal for...

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...
