What would you like to choose for your next embedded project an FPGA or a microcontroller?
http://zurl.co/z0Em
Built around a microcontroller (MCU) or a microprocessor (MPU), a development board allows a learner to get the correct design, along with the required speed and convenience to create an easy, interesting and foolproof project. The idea behind the creation of a development board was to make the task of a product designer easy. However, …

Let us create a simple low-cost automatic lighting system.
http://zurl.co/Ac1KKEwq1oR
Solar streetlights can be easily integrated with a dusk-dawn controller by simply employing a pnp transistor and a few resistors where the solar panel itself works as the sensor. But what about other lighting sources that do not employ solar panels such as automatic lighting systems in small wind turbines, automatic lighting in cars or …

Let us create a simple solid-state relay (SSR) switch, controlled by a standard passive infrared (PIR) motion sensor module.
http://zurl.co/z0kA
This circuit is designed for use with all kinds of medium-power automobile/domestic 12V DC loads. It is a simple solid-state relay (SSR) switch, controlled by a standard passive infrared (PIR) motion sensor module. A PIR sensor is an electronic device that can measure IR light radiating from objects in its field-of-view. Apparent motion is detected …

#DIY: Plus-minus 5V Supply From 9V #Battery
http://zurl.co/OVxo
Op-amps require dual-polarity supply for proper operation. When working with battery supply, it becomes difficult to get dual power supply for the op-amps. Presented here is a simple circuit that provides ±5V from a 9V battery. Circuit and working The circuit diagram for the ±5V supply from a 9V battery is shown in Fig. 1. …

#DIY #Project: Earthquake Indicator
http://zurl.co/xjBv
An earthquake is an unavoidable and unpredictable natural phenomenon that often causes damage to lives and property. We cannot fight it but we can stay alert and aware using technology that can protect us and the industry. Here a simple earthquake indicator for home and industry using an Arduino and a highly-sensitive ADXL335 (Fig. 1) …

To engineer drones that can handle next-generation applications, let us take a look at the technologies available for you.
http://zurl.co/2jAJ
First shown at CES 2016, Etos is a BMW i8 with an auto-pilot and a drone onboard. Frank M. Rinderknecht, boss of the Swiss creative think-tank Rinspeed, intends to use the UFO-esque drone on board Etos for performing services such as picking up deliveries from stores as the car drives you home, while you relax …

Make your own ultra-sensitive fire sensor that activates an alarm when it detects fire.
http://zurl.co/n3ZR
Here is an ultra-sensitive fire sensor that activates an alarm when it detects fire. Thermistor based fire alarms have a drawback; the alarm turns on only if the fire heats the thermistor in close vicinity. In this circuit, a sensitive PIN diode is used as a fire sensor for a longer-range fire detection. It detects …

Do you want to enhance the AC input impedance of audio amplifiers that are used with pickups in musical instruments?
Check this #circuit out!
http://zurl.co/06VB
The buffer circuit described here can be used to enhance the AC input impedance of audio amplifiers that are used with pickups in musical instruments. Some signal sources for preamplifiers, passive pickups for electric guitars or sensors based on capacitors require very high-impedance of over 5-mega-ohm. This can be achieved easily with junction field effect …
