-# InsoLED
-## Overview
-In a few words, it's a LED-based PCB exposure box. Most designs of PCB exposure boxes are based around UV-tubes, or a lot of 5mm UV leds. I chose to try with 1W UV-LEDs. The design aims to be:
-* Portable
-  * Not fragile, like UV-tubes are.
-  * Small, since I rarely need to expose an A4-sized PCB.
-  * Big enough for standard sizes of PCB, I chose to go with 100x160mm which is already more than what I'm used to.
-* Easy to use
-  * Autonomous: Put your PCB in, start, come back when it's done
-  * Adjustable, since different PCB, traces sizes, ... require different exposure parameters.

-* The first one is the first prototype, on a breadboard, with a Teensy2.0 instead of an Attiny44
-* The next two are the actual prototype (there was a mistake on the PCB, involving a quick fix to get the backlight)
-* The last one is the Power Interface to drive the LEDs, it's a phototransistor (4n35), followed by a N-Channel Power MOSFET. And yes, this is ... messy, but it works as expected, so I might integrate it in the next revision of the PCB

-## SVN Repository
-Right now, that's the only resource available. The whole project is under GPLv3, so feel free to improve it.
