    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...
    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...
    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...
    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...
    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...
    DIY Counterfeit Money Detector Project Counterfeit bill/money detection is an everyday necessity in this world of smart printers and hi-tech criminals. Most modern bill counters, equipped with counterfeit money detection, will scan for ultraviolet (UV) and magnetic (MG) properties. These bill counters count bills at a speed of hundreds of bills per minute. As the...
    DIY USB Condom Circuit In a commercial manner, “usb condom” is a security device for preventing data theft through universal serial bus (usb) interface, and is widely used by many smart phone owners to protect their valuable datas from “juice jacking”. Since most of the smart phones on the market have been designed to employ the same...
    TTP223 Capacitive Touch Switch Circuit Here is a simple capacitive touch switch circuit for electronics hobbyists. Even though the circuit uses smd components, construction of the touch sensor switch is not very hard because the whole circuit can be easily fabricated on a piece of smd prototyping board. At the heart of the circuit is an inexpensive (`20) smd chip...
    ATtiny2313 Minimum DIY Development Board This article shows you how to build your own ATtiny2313 microcontroller minimum development board in an inexpensive way. The ATtiny2313 microcontroller is a small, economical, yet powerful microcontroller convenient for running many little – to – complex level microcontroller programs. ATtiny2313 The ATtiny2313 microcontroller...
    Vending Machine Drop Sensor Circuit Microcontrollers come in all sorts and sizes, and it’s very tempting to use them everywhere. If you are in a plan to build your own Vending Machine, probably you need a microcontroller-compatible Drop Sensor circuit. In a commercial vending machine, its delivery chute uses a drop (vibration) sensor to detect whether product is...
