Homebrew PCBs

If design and code was available, would you build one? What
features should it have?
 
Uses
	* Check your safe light
	* Check your light box
	* Check your photoresist

	* Share results with group
	* Consistent results regardless of light source
	* Use the sun

 
Design ideas
	* Battery powered
	* Thin sensor at end of FFC (fit under glass)
	* Display can be pointed in any direction
	* Display dose in mJ/cm^2As for the photodiode, I thought that the ML8511 would
work well. It outputs 1.0v at 0 mW/cm^2 (no UV light) with constant slope to
2.8v at 15 mW/cm^2 (lots of UV light).
