    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...
    DIY Linear Actuator Controller Linear actuator uses a lead screw driven by a permanent magnet dc motor to create linear motion from a dc voltage. When power is removed linear actuator will hold its position. However, if a force large enough to overcome the internal friction is applied, the actuator will back drive. Here is an ultra-simple circuit to connect...
    DIY DS1307 RTC Module Although ready-made real-time clock (RTC) modules for microcontroller projects are available in every online shop, an inspired electronics hobbyist would rather put together something from a few components that happen to be lying around. Now a days, most microcontroller projects those which log or track data information often...
    Hand Crank Generator Here is the circuit of a compact hand powered generator that can awake little electronics by hand crank. This is a great vacation device that you can rely on to operate your small electronics. The prototype generates up to near 150mA of current at 5 volts, enough for a wide range of minuscule devices! It is easy to use a small...
    Hot Glue Gun Hack: Temperature Ready and Power Indicator Hot glue gun is an indispensable tool for electronics hobbyists and professionals. Reasonably priced glue guns (and glue sticks) are now widely available, but most of the low-end type have a serious drawback – the lack of a power status indicator! If you have enough skill level and patience, you can easily add a simple...
    PCB Laminator I used to design my PCB using one of the free pcb design software available on the website and then using the toner transfer method with an electric iron tried to transfer the toner from the paper to the printed circuit board. I must say that the end results were pretty good but not too good so I decided to find another way of...
