A ideia deste projecto surgiu-me quando um dia estava a aceder remotamente ao meu PC para consultar uns trabalhos e imaginei que desta forma e ligando uma webcam poderia ver o que os meus gatos andariam a fazer quando sozinhos. No entanto precisava de algo mais pois a webcam pousada no topo do monitor não […]

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push button increment of the counter from 0 to 9. The whole circuit can be powered from a standard 9V PP3/6F22 battery, or […]

Have you ever wanted a smart home that can automatically adjusts the blinds for you? If so, this project is for you. In this instructable, the author describes his approach to “smart blinds”, by using an Arduino board, an ethernet shield, a motor shield and a couple of sensors. By means of a simple web-based […]

Introduction The Paper-Duino-Pi is an Arduino shield for the Raspberry Pi. Due to the fact that it is designed as Paper-PCB it is easy to create and one doesn’t need a printed circuit board. All components are standard electronic parts that are easily available at your favorite electronic shop. Plus they are really cheap. All […]

Teensy-LC (Low Cost) is a powerful 32 bit microcontroller board, with a rich set of hardware peripherals, at a very affordable price! Teensy-LC delivers an impressive collection of capabilities to make modern electronic projects simpler. It features an ARM Cortex-M0+ processor at 48 MHz, 62K Flash, 8K RAM, 12 bit analog input & output, hardware […]

Electronic Brick, Waterproof and other Versions NOTE: There are different-appearing versions but they work the same. This is an electronic thermometer which has high accuracy over a wide range (accurate to ±0.5°C over the range of -10°C to +85°C) (Workable from -55°C to +125°C). You can locate these thermometer chips up to 100M away from […]

A 100% Arduino IDE compatible, 32KB USB development board small enough to fit on your fingertips and cheap enough to leave in any project. NOTE: In case you have forgotten to add shipping charges while pledging. Please make another contribution equaling the shipping charges (using the same e-mail ID previously used), and DO NOT select […]

EMI mains filters Schurter combined with an input AC connector will stop interference there, where it´s the most efficient – at the input. To be more precise, usually it´s the best to eliminate interference (EMI) already at a source of interference itself. But because there are a lot of disturbance sources in a common 230V […]

I try to have a few different projects on the go at any time — a big, long term project (like the Arducorder), a shorter-term fun project (like the Open Source CT scanner), and a bunch of smaller weekend or few-weekend project (like the open mini spectrometer). Having a few projects of varying time scales […]

If you are contemplating building your own machine, then you probably already know a good bit about how pinball machines work. It’s basically series of electro-mechanical events where a steel ball activates a switch, which in turn fires a solenoid that drives a mechanism, sending the ball off in some other direction where it most likely hits another switch, and so […]
