Tag It!
[2008.05.23] 
I picked up one of the final collector signs from Public Works today, and brought it home along with some strange looks I got as I carried it past the the hordes outside of various pubs. The final part in place and it's all working well, save for the circuit being wired anti-clockwise, though that's easily solved.

Putting it all together
[2008.05.22] 
After a long block soldering, unsolder, re-soldering, I've finally managed to get all of the data collector box together, and this is what it looks like before it's boxed up. I've soldered the extra components and controllers onto an Arduino 'ProtoShield'. I made a few silly mistakes, but they were easily fixed.
The protoshield means I can easily replace the various components if there is a failure, especially as the cables are all attached via screw down terminal blocks. The code for the Arduino board is pretty much complete, but I want to do some thorough testing before I finally load it onto the microcontroller without the Arduino Bootloader.

Start & Stop
[2008.05.19] A small milestone, seeing the start/stop buttons work in context as I do final tests to the prototype

A third and final prototype..
[2008.05.19] 
I've made the final prototype for the data collector, complete with stat-stop switches and a status indicator LED. It's much much simpler than I expected when I started this project, and that can only be a good thing in my book. Now to get soldering and get it all into the box, which I picked up from Public Works today.
Whilst I was at Public Works earlier Andreas showed me some of the signs, and I also picked up the final box for the data collector, and started fitting it out.

Memory Maps of San Jose
[2008.05.19] I'm going to be heading out to San Jose ('do you know the way?') next week with Julie Myers to work on some workshops with her, as part of Zero 1 festival.

Prototype 2 (or 3?)
[2008.05.13] 
Having waited for the Tirna Electronics to mount the one-wire controller chips from Maxim I've inserted their chip into the circuit and was more confident that it's my dodgy code that's the problem reading the one-wire network, so I got back into the code and now have it working, a set of code for searching and manipulating a 1-Wire network via IC2 and a DS2482-100 One Wire Controller... the next step is to swap in a DS2482-800 and try and read multiple inputs.
