History

Version 0.1
A picture of the breadboarded version.
This was the first version that I built. It is on what is known as a breadboard. It is being controlled by an Arduino Duemilinove. This is what I used to make sure the code was right.
Version 1.0
A picture of the perfboard version.
This is the first wareable version. It is built on a perfboard, or a board with evenly spaced holes and copper pads that isn't designed for a specific use.
A picture of the perfboard version's back.
Here is the back. I just taped on a pipe clamp to test the size.
A picture of the perfboard version's wiring.
Because the board didn't have all of the right connections I had to use point-to-point wiring. I used magnet wire to connect the leads on the back of the board to where they needed to go It wasn't as easy as I thought it should be.
Version 1.2
A picture of the Version 1.2.
This was the first production version. There were several things wrong with it, designer error mostly, but most notably the batteries were backwards which casued shorting so we put little paper strips to insulate. The button was also wired incorrectly.
A picture of the Version 1.2 back.
This is where you can really tell that the button is bad. I had to cut some of the traces on the front and then use point-to-point wiring on the back to fix it. This board measures 2.5" x 3" so it's a half an ince taller than the current versions.
A picture of the Version 1.2 copper.
Instead of using silkscreen on the back, all of the text is in copper. This didn't turn out as cool as I thought it would be and it's a little hard to read.
Version 1.3
A picture of the Version 1.3 front.
I redisigned the layout so the board is now 2" x 3". This fit better on the large panels. This was another expensive mistake. The button didn't work again because of designer error.
A picture of the Version 1.3 back.
I cut traces again and rewired the button. Lesson learned.
Version 1.4
A picture of the Version 1.4 front.
This is the current version. It all works right the first time, thankfully.
A picture of the Version 1.4 back.
Notice no extra wires on the back. Sweet!
