# 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.
## Pictures
* 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
