It’s been quite a few months since I first ordered my xbee modules and today I finally had a little time to plug them in and do some testing. To my surprise it was a fairly simple task to get them to send and receive messages between two notebooks using maxstream’s X-CTU program. X-CTU is a tool made for programming and updating xbee modules it also comes with a terminal which comes in handy at times. Getting the xbee’s talking in Max/MSP seemed to be a sinch as well. You simply need to set up a serial send and receive patch and there you have it, small and fast wireless solutions. Here’s a short video of what I did today and you can download the max patches that I used for this demo. I can’t really see a practical purpose in using xbee modules in this way but it seemed to me to be a good starting point to get my xbee projects started.

My aim for the future is to create a wearable system for choreography using these small xbee modules. Rob Faludi has an Xbee direct blog entry that I hope to get going in the next few weeks.

del.icio.us is a site that you can store all of your bookmarks in. It comes with a firefox extension to make it pretty easy. When you format your hard drive you don’t loose your bookmarks!! my page

the other day i bought a breadboard with the aim of doing some serious learning about electronics. After a few failed attempts tonight i managed to complete a working 555 timer circuit that switches between 2 different coloured LED’s. I knows it’s a fairly minor feet but it’s a fairly exciting start none the less. The circuit involves a capacitor that is alternately charged and discharged to control the 555IC between +9v and -9v on the rail. YAY… in other exciting news I made (on my new breadboard of course) an accurate to +-100mv a 5vDC voltage regulator circuit which involves capacitors, transistors and lots of other fun stuff. Here’s the photo’s of my breadboard exploits.

Electro Graf

March 6, 2008

On tuesday i started to make an electro-graf peice. Although James had already said that electro graf was probably not worth it, i decided to go ahead. So I bought a circuit writer pen from jaycar and started writing. It worked pretty well until i realised that the strips didn’t really take that much current. So I had made each letter a different circuit and voila!!! IAD electro graf.

GRL workshop

March 5, 2008

This week I’ve been involved in a workshop with the guys from graffiti research lab evan and james. It’s been pretty cool so far, we’ve videos on graf writing, made throwies and are in the process of constructing a laser tag 3 wheel bike/broadcasting station.

They have a film out that recently screened at sundance. they have released the DVD ISO torrent on the net which you download here.

Some other links we’ve been shown.
