Finding and Fixing Phone Line Noise If you’re still desperately reading this article, then your landline problems probably aren’t caused by weather. A simple way to determine the source of the noise is to remove each potential suspect one by one until the noise goes away. For instance, disconnect all the other phones to see […]

How Bone Conduction Works To understand how bone conduction works, you first have to understand how we hear sounds, which we do in two ways: Sound travels in waves through the air. Normally, sound waves travel through several structures in the ear, before being translated and transmitted through our nervous systems to our brains. First, […]

With LEDs that require only one pin, you can do a lot with even just a 6-pin microcontroller! A touch controlled light with 4xWS2812 RGB LEDs and ATtiny10. This is a small hardware project which utilizes the light_WS2812 library and the TinyTouchLib to implement a touch-button controlled RGB-LED light. Only two output pins of the […]

As a result of visiting Hamfest, I ended up with a laptop to take apart – a fairly new Toshiba Satellite C675D with a broken screen. It’s not a Hamfest if you don’t bring home something to take apart of course! Today we’ll be testing the battery it came with to see if it’s salvageable.The […]

Gizmondo Design At its core, the Gizmondo is built for gaming. It looks a lot like a controller for a console game system, except for the view screen in the middle. The Gizmondo is roughly the same size as a controller, with four gaming buttons on the right, an eight-way game pad on the left, […]

Integrated circuit FT232R is becoming legendary and we bring you another example of FTDI USB chips usage. In praxis we often face a requirement to communicate with devices, which have serial ports RS232, RS422 and RS485. As many devices – mainly notebooks, already usually don´t have these ports, it is necessary to use a converter […]

Packet Switching and VoIP VoIP uses packet switching rather than circuit switching. Instead of leaving an entire circuit open during the whole conversation, it breaks the conversation into small packets of data. It then transmits that data over the Internet. Instead of monopolizing a circuit, packet switching sends and receives data as needed. Click “Play” […]

In my last projects, I always use the same CPU. DSETA board, I say in the posts. Well, here it is, a CPU based on the AT89C51RE2 microcontroller from Atmel. I develop this board for some reasons. The first and main one is because I want to have a small board with a great (an […]

Avatar Machine Hardware Apart from the costume elements of the invention, which were included to give the Avatar Machine the appearance of a video game character, the device includes: A harness that straps to the user’s torso Three two-meter long aluminum rods that attach to the user’s harness at the lower back and shoulders, forming […]
