    Arduino tutorial  

    Layman’s Camera Remote Control It’s sensible to use a remote control when your camera is mounted on a tripod, especially when you are using slow shutter speeds. The stability of even a high-quality tripod can be compromised if you touch and jostle the camera while taking a shot. A camera remote control enables a more hands-off approach. An Insight The core of this...
    Arduino I2C LCD Backpack Introductory Tutorial Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance Arduino, you would need atleast 6 I/O pins to talk to the LCD. However, if you use an LCD module with I2C interface, you only need 2 lines to...
    Compact RC Switch Circuit If you are an RC modeller, then this circuit is for you! The compact RC Switch let you turn something on and off from a regular R/C channel. The device is powered entirely by the receiver, drawing only limited current, and switched output load is electrically isolated from the R/C circuit, allowing two completely separate grounds to run without...
    Geiger Counters – Not So Hard To Build Although they’ve been on the shelves of many online retailers for quite a few years now, Geiger-Tubes have been conspicuously absent from hobby electronics magazines/websites. It has to be said that building Geiger Counter circuits, especially if we set ourselves a certain level of choice, is far from simple — or rather, was far from simple, until these recently...
    Dehumidifier Hack What does one do when the electronic control of a modern dehumidifier goes south? Simple; gut the electronics and replace the intelligent control with a simple, old style, reliable humidistat –not as simple a task as it may seem, but a rewarding exercise. Background One of my money-making sidelines is repairing and refurbishing of old dehumidifiers. Since they are...
    DIY CAN Transceiver CAN or Controller Area Network is a bus standard designed to allow microcontrollers and devices to communicate with each other without a host computer. Here is the construction details of a do-it-yourself CAN-Bus transceiver using the Microchip’s MCP2551 High-Speed CAN Transceiver IC. The output pins of this circuit can be configured for use with an OBDII cable or a...
    DIY Steam Sensor For Microcontroller Here is the circuit diagram of a simple steam sensor, wired around a handful of inexpensive components. This steam sensor can be connected to a microcontroller’s I/O port directly. The steam sensor works by having a sensor pad with series of exposed traces connected to ground rail, and interlaced traces between the grounded traces connected to the input of...
    Retro Handset For Mobile Phone Once again here is a true recycling project – turning an yesteryear’s telephone handset into a general purpose retro handset for today’s mobile phones. Recently, I bought one piece of the trendy “mobile phone retro hansdset” from an online store. Unfortunately the cheap, chinese-made, little gizmo failed to reach up to my expectations both in physical and technical aspects....
    ESD Protection For USB There are a number of solutions for connecting your do-it-yourself project to a computer. Serial ports are easy to use, even if you have to do so via a universal serial bus (USB). The advantage of going through a USB port is that operating systems already include the drivers for defined types of data. For example, USB uses classes...
    Bistable Relay Tester Bistable relays (BR) are widely used in battery powered equipments or applications with “memory function”. No doubt, when it comes to an average electronics hobbyist, bistable relay is a mysterious component. In principle, for remote and automatic controls there is often a need for switching contacts which have two stable contact positions, even in the defunct state. This requirement...
