A robot that I made was featured on Hackaday today: http://hackaday.com/2011/06/19/the-party-popper-security-robot/
This is the original video: http://www.youtube.com/watch?v=1h31h7341vY
I will be uploading a much higher quality video (HD) over the next couple of days going into it's more complex features such as HD webcam aiming and people identification.

WiFi is one of the great inventions of the 21st century in my opinion as it allows you to access internet wirelessly at high speeds. But it has one major downfalling: it's range. Enter the world of Wokfi.This is the art of combining asian cookware with a USB WiFi Dongle to make a long range WiFi antenna. These antennas can increase range 4 to 6 times. I'm thinking of building a big one of these to put on my roof (like an old foxtel dish or something) so I can reach some macdonald's WiFi spots and download to my heart's content.

The Parrot AR drone is a pretty cool toy and I've been thinking of buying one for a while. But there is a problem: I don't own an iPod or iPhone to control one. Enter the AR Drone control application built by Stephen Hobley and some of his friends. This stuff is in my opinion way cooler than the standard control apps and it allows you to fly with a joystick. Just think, you could make a missile launcher using the extra USB pins on the main board (http://www.dronehacks.com/) and shoot by flicking the kill switch on the joystick. Awesome.

I was wondering the other way how I might be able to make the webcam stream from an NXT robot wireless when I came across this. It's basically an adapter for NXTs (lego mindstorm robotics brick) so that they can use Xbee radios which are commonly used with Arduinos and the like. Xbees offer a faster alternative to communication than the standard Bluetooth that NXTs use. This allows you to do more complex wireless projects like webcams and other high data applications.

This is the stuff I'm planning to order today. It's got a hell of a lot of stuff for the money compared to ones from adafruit, sparkfun etc.

Unless you've been living under a rock or something you will know about the new action bus cards called MyWay cards. These are essentially an RFID system that is hooked into a database somehow to access account info. You put money on, you get bus ride. The scanner machines are very simple yet are often broken or malfuctional. I've always been wondering whether you could build a system to knock them out with a bit of electromagnetic radiaton. All you would need is a backpack and some coils and control electronics.

I was having a look the other day at Hackaday's devoboard breakdown and they had as their cheapest option the TI launchpad. This is basically a simple dev board for the MSP430 chip. And it's very cheap at $4.30. I just wish someone would make something like this for an AVR chip....
Here's the website:http://processors.wiki.ti.com/index.php/MSP430_LaunchPad_(MSP-EXP430G2)

This is the first blog post for a web site that I have created to service hackers in the ACT. The main aim in creating this website is creating a place for hackers to talk in Australia. This website will cover programming (C, Python, AVR programming etc) and practical hacking (robots, electronics, Arduino etc).It will be a place for hackers to share information and knowledge with other hackers as well as a place for them to organise meet ups and get togethers. In short, it's going to be really cool.
