The ZaCon badges were a ton of work on the hardware side (see ZaCon V Badge [1/2]: Build Time), however they provided their own challenges on the software side as well.

Since my knowledge of chipsets only extended to the Arduino the badges are essentially a complete Arduino without the UBS->FTDI breakout. This means that each badge includes an Arduino bootloader which is _really_ nice if you are coming from an Arduino background or simply have an Arduino and want to play.

The idea behind the badges was that they would provide a means of tracking communication between individuals at the conference. Additionally I wanted this information transmitted to a central location so that it could be stored and visualised (yes yes, Maltego and all). Additionally because people would be moving around I needed to create a ‘mesh network’ of sorts so that anytime someone came into range of any other badges they would be automatically be part of the network. This blog entry is going to cover how the badges did this and the challenges faced, if you are not interested make like a heartbleed and go away.

Eye Candy:

Here is a video of a few of the black badges communicating to each and flashing for all the valid messages received:

So its been ages since i last blogged, and i am determined to try do this more regularly since it will probably get me onto doing more stuff!

This is pretty much the first thing i built with the Arduino – the idea was to make a budget IPCam with a web interface that i could connect to from anywhere and have the ability to pan and tilt my camera. Since i was in the budget price range i did also look at what was available off the shelf — and it sucks, bad quality, slow response time, no lose wires to show, all things i’m not really interested in.

I’ve split this into 3 sections just to make sure that this doesnt become a massively long blogpost:

This is that cool part where you watch the video, unfortunately i haven’t got round to making one yet.. but when i do, its going here! For now, its in pictures (the webinterface and the actual device):

So i’ve commented most of the lines and you should be able to easily follow what has happened in the code. Leave a comment if there are any questions :)

So i see its been forever since i have posted anything, figured its about time, and i wanted to show some of the stuff ive done with my Arduino. The first thing i tried to do with it was create my own budget IPCam with a webcam and some arduino parts.

Basic stuff that make up the IPCam:

  • 2x Servo Motors
  • 1x LCD (16×2)
  • 1x LED
  • 1x Potentiometer (used for LCD)
  • Bits of random Meccano
  • 2x Small lifting weights ( hey, we all knew i wouldnt use them to get in shape anyway )
  • Tape/Glue/Random stuff

So first off, this is a hack, i havent done pretty much anything properly, i just pieced it together, tied in bits of code and got it working :)

This is what the circuit looks like:
