Toast Talker

Sound – Audio Project Ideas / By Ibrar Ayyub

This Instructable started as my great interest in the TV show Toast of London. The British Matt Berry comedy that can now be found on Netflix has some superb voice overs that I wanted to accommodate in my morning toaster routine. In a running joke, he was required to make recordings for the British Navy for their

Portable Luxmeter

Battery Projects / By Ibrar Ayyub

This project is about making portable luxmeter. It can be used in schools, where children can measure different kinds of light sources.Functions: 1. measure intensity of light in lux. 2. calculate solar irradiation from lux to watts/m2 (factor 112) 3. charging battery using USB port Total cost is around 13 $ without case. Luxmeter take 15 mA, so

Dev Board Breadboard

Other Projects / By Ibrar Ayyub

This Instructables show how to create a tailor-made breadboard for dev board. Step 1: Current Breadboard Breadboard (solderless breadboards) is a very import component for prototyping of electronics. It can help you test the circuit before soldering it. Since the connection not require soldering, after the prototyping, all components can be reusable for next projects.

Home Presence Simulator and Security Control Device

Security – Safety Projects / By Ibrar Ayyub

This project allow us to simulate presence and to detect movements in our home. We can configure a network of devices installed in differents rooms of our home all of them controlled by a main device. This project combines these features on a single device (PICTURE 1): It is a presence simulator: the device switchs on and off one
