ArcReactorX

I etched my board using the traditional toner transfer method. Its a bit tricky to get those 10mil tracks for TSSOP packaged MSP430 but eventualy with practise its easier to achieve.

I cleaned the  copper clad and ironed the laser printed photopaper on it and then used my OpenAgitator(Build urs here) to eat away the copper while i drank tea.

I then soldered the components and shaped the pcb like a Tazo with groves cut so that i can either sew it or use a velcro later.

Based on the requirements i made a quick schematic and board in Eagle available here. The size of the circle depends on the chest size a lot. Imagine hulk wearing the arc reactor (LOL). 

So, i used an A4 and drew circles of various sizes 5cm , 6cm ,7cm and 8cm. I then used a tape to stick them on my tshirt and see if it looked fine. 

I went with the 70mm dia one.

It looked cool.

There were a lot of space on the board left. So, i wrote stuff on it. Made the open source h/w logo. Since, the project is open source. 

Make and spread the Iron Man-ism :)
