Logitech’s latest product is a wireless keyboard with an integrated solar panel.The product, which is Logitech’s first light-powered keyboard, can work in total darkness for up to three months and will charge up from artificial light sources such as lamps. The Wireless Solar Keyboard K750 is powered completely by the sun and will even work [...]

This video is made by  Karl Von Moller and is called “State of Electronics” – A discussion on the Electronics Industry in Australia. The discussion is focused initially on the world of Hobby Electronics and how it’s decline could effect the Electronics Industry in the future. The Documentary then discusses many issues that face industry [...]

This application is tested only with Samsung Galaxy GT-i5700 Spica (rooted Android 2.1 OS, i570EXXJD1 Baseband version). The transmitter circuit uses Microchip’s dsPIC33FJ16GS504 for the analog-to-digital conversion of the input signals on two channels. The processed data on the dsPIC are then transmitted to the phone (for waveform display) via the LMX9838 bluetooth SPP module. [...]

Serial RS-232 (V.24) communication works with voltages (between -15V … -3V are used to transmit a binary ’1′ and +3V … +15V to transmit a binary ’0′) which are not compatible with today’s computer logic voltages. On the other hand, classic TTL computer logic operates between 0V … +5V (roughly 0V … +0.8V referred to [...]

This is a very simple circuit to make using a 555 component and is recommended for the electronics beginner. The idea is to have a flashing red led indicate that your car is protected. This device can protect your vehicle from potential thieves – it makes it look like your car has an armed alarm [...]

Is that crackling and popping when you turn the controls on your amp driving you crazy?  Here’s how to clean them and get back to the music. There are spray “contact cleaners” available for this purpose, but in most cases just mixes the dirt and grime already inside with more dirt and assembly grease and [...]

When you make MOSFET assemblies with especially when they are retrieved must be checked before assembly. This may seem very simple checker can check all N-type MOS-FET. Source: soloelectronica

The TV-B-Gone is a neat little device that can turn almost any TV on or off. It uses a microcontroller hooked up to IR LEDs to output a library of on/off codes. Adafruit sells a kit, and has the code as well as the schematic on their website. Here’s a micro clone of the TV-B-Gone [...]

iCircuit is the premier iPad and iPhone app for designing and experimenting with circuits. Its advanced simulation engine can handle both analog and digital circuits and features realtime always-on analysis. It is the perfect companion to students, hobbyists, and engineers. You use it as you would any CAD program: you add elements, connect them together, [...]
