Adding LED to steampunk style brass goggles.

I have already finished my DIY brass goggle in steampunk style. I also published of making stuff here Making brass goggles. 
I added LED rings to my made steampunk style brass goggles.
I also changed some parts of the goggles to improve.

 Actually I chose Arduino mini pro 3.3v 8Mhz. But It's a little slow to light complex LED patterns.

 The LED rings were made by Adafruit. Although I tried using chinese made one, that was always noisey.

 The idea of using tracing paper on the inside of glasses is Adafruit's idea.

 Lipo battery was attached. The opposit side has micro computer.

 I noticed the part of circuit needs cover. I tried looking for it in glossary shops, but I couldn't find good one. So I made it.

 The brass sheet's thickness is 0.5mm.

 Bend, bend.

 Then I soldered the 2 parts with hard silver solder. That is my way which I can use well.

 I bought brass hitch. It's very thin.

 After soldering. looks very dirty.

 I use a cleaner to clean toilette to clean soldered one. The cleaner includes a little acid.

 Not so bad than I imagined it at first.

 Then I attached micro computer and swith inside of the brass box.

 I used double sided tape to fix the connector and micro computer.

Finished assembling.
I programmed LED pattern for it.

 This designing way was thought by myself.

 It's useful to think how the program is written.
