Enter the Esplora, Arduino game controller

Leave a Comment / Blog, News / Ibrar Ayyub

Welcome the new Arduino – the Esplora ! It’s shaped like a game controller, and it’s designed to be used out of the box as it comes with many sensors and actuators already on it (you can add a couple of extra ones). In more detail, the Esplora combines a light sensor, a temperature sensor, a 3-axis accelerometer, a joystick, a set of pushbuttons, a slider, an RGB LED, and a buzzer, together with a Arduino-compatible processor (ATmega32u4).

Computerised board game wins Raspberry Pi Hack Day

Leave a Comment / Blog, News / Ibrar Ayyub

The UK’s first Raspberry Pi Hack Day has been held, with the winner of “Best Overall Hack” being a virtual board game suitable for educational use within schools. The 24-hour bake-a-thon, hosted by CPC in Leeds, focused on programming solely using the credit card-sized Raspberry Pi, and the winning team – Spooks – developed a board game which encourages players to experiment with programming

What is a stun gun – How to Make Stun Gun

Leave a Comment / Blog, Circuits / Ibrar Ayyub

What is Stun Gun An electroshock weapon is an incapacitant weapon used for incapacitating a person by administering electric shock aimed at disrupting superficial muscle functions. One type is a conductive energy device (CED) fires projectiles that administer the shock through a thin, flexible wire. Other electroshock weapons such as stun guns, stun batons, and electroshock belts administer an electric shock by direct contact.

How a Microwave oven works?

Leave a Comment / Blog, Circuits / Ibrar Ayyub

Bill details how a microwave oven heats food. He describes how the microwave vacuum tube, called a magnetron, generates radio frequencies that cause the water in food to rotate back and forth. He shows the standing wave inside the oven, and notes how you can measure the wavelength with melted cheese. He concludes by describing

SKL14 -1A Schottky diode will fit everywhere

Leave a Comment / Blog, Circuits, News / Ibrar Ayyub

SKL14 can be used in switch-mode power supplies or as protection diodes and thanks their really miniature dimensions, they are also suitable at the lack of PCB space. SMT Technologies enable a substantial increase of current density thanks to a very good heat transfer from a component to a PCB. Almost a zero length of „leads“ of SMT components also features another positive aspects like a significant suppression of a parasitic inductancy and a possibility to construct circuits with a high components density and a minimal PCB tracks length, what significantly decreases an undesired radiation (EMI) for example in switch-mode power supplies
