Arduino Ouija Board
https://www.electronics-lab.com/arduino-ouija-board/
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 moved about the board to spell […]
Simple Electronic dice
https://www.electronics-lab.com/simple-electronic-dice/
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 way […]

LT6658 – Precision Dual Output, High Current, Low Noise, Voltage Reference
https://www.electronics-lab.com/lt6658-precision-dual-output-high-current-low-noise-voltage-reference/
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 driving the precision reference inputs of high resolution ADCs and DACs, even with […]
Capacitor self-diagnostics
https://www.electronics-lab.com/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 occurs. Thus, any chance to monitor the condition of […]
