While dial clocks are functional and well-understood, for something a bit more uniquely styled, Luuk Esselbrugge has created a 3D-printed timekeeping unit with four rows of sliding numbers.



As seen here, each digit moves up and down to show the appropriate…

A TTL/CMOS based clock that displays the time along a 60 LED bargraph.

I like clocks. I like LEDs. I like mucking around with circuits. I want to make a clock that displays the time along an LED bargraph without using a microcontroller.

Only minutes…

Los tipos de datos básicos en Arduino son algo muy importante a la hora de desarrollar nuestro proyecto. En este capítulo te lo explicamos.

Fetch data directly on your ESP8266 or ESP32 even when there is no public API available.

A self powered 18650 Lithium-Ion battery discharge board

The charging circuits that I design need discharged batteries. Power resistors alone are not enough because when you forget the time they will discharge to all the way to 0V and damage the batteries.…
