DIY – Simple LCD Control with Ethernet

Posted on February 21, 2007 by max

Here’s a cool project that you can control your LCD with ethernet.

The simple “switch on/off a relay” circuit which was the only function provided by the avr web server until now did not require HTML-forms. I used simply 2 URLs http://baseurl/password/1 for switching on and http://baseurl/password/0 for switching off. This does not work anymore for the display as we want to type a text into a web page which should then be shown on the display. What is needed is a needed is a proper decoding of HTML form data.

DIY HACK – Voltmeter Ammeter LCD

Posted on February 21, 2007 by max

Check out voltmeter and ammeter LCD panel you can make using an Atmel8 MCU. Tight!

This multimeter was designed to measure output voltage and current in a PSU, where the current sense shunt resistor is connected in series with load at the negative voltage rail. It needs only one supply voltage that can be acquired from main PSU. An additional function of the multimeter is that it can control (s

Here’s an update of controlling 3 stepper motors using a CUBLOC CB280 module. Although you can move the motors simultaneously, there are a lot of applications you can use it for.  Sorry about the video, my video camera needs head cleaning.

We’ve been messing around with some industrial stepper motors at work. These Xylotex stepper motors are pretty cool.

We have an example here for interfacing with some CUBLOC modules.

We got the 3-axis stepper kit so we will have a 3 step

Ethereal – Free Network sniffer tool for embedded TCP/IP applications

Posted on February 7, 2007 by max

This is the best sniffer for embedded TCP/IP applications in my opinion. There a lot of options such as HTTP filtering, UDP, TCP, DHCP, and you can also use it for capturing packets to break WEP codes… (not that i recommend it.)

Commodore PDA

Posted on February 7, 2007 by max

Here’s a 64KB Commodore PDA system that runs BASIC. Tight!

Here are a few pics of my own DTV Hummer project. I had an old PSOne LCD screen lying around and I thought I’d make a C64 laptop. Actually, it’s more like a C64 PDA! It measures 6.5 x 6 x 1.5 inches (15.5 x 16.5 x 4 cm) when closed. It can run from an AC wall adapter or 6 NiMH AA batteries. The keyboard is hacked from a portable folding keyboard for a Jornada PDA which outputs RS-232. I&#

DIY – AVR based Bucket mousetrap

Posted on February 7, 2007 by max

video://www.youtube.com/watch?v=Mz5ds5hV2HU

Here’s a cool little project for capturing mouse!

This project captures a mouse by having a solenoid (electromagnet) drop a bucket over the mouse. The bucket is triggered by the mouse interrupting one of the infrared emitter/detector pairs around the bait. The enclosure that holds the electronics is mounted directly over the bait. Ok, so the “bucket” is actually a semi-clear storage container. The clear container allows a person to see i

DIY – Nomad Autonomous Buggy

Posted on February 6, 2007 by max

Here’s a nice little RC buggy for future reference on RC mods…

This was probably the most important thing to achieve. The R/C vehicle that I’m using has 2 servos, one to move the position of the front wheels and therefore controls steering and the other controls a mechanical speed controller (push it forwards and you go forwards, backwards and you reverse with an zone in the middle of not moving).

Servos are driven by a PWM signal which allows accurate positioning of the servo &
