So after ordering one which cost about $295 dollars and building it took about a day(probably should have taken less time but I was willing to take my time) the great mod had began.

Here is a list of what I have bought or already had or going to purchase for this project the list includes estimated price:

1)WaterColorBot: $295.00 Source : www.evilmadscientist.com
2)Laser 2W 445nm with Current Regulator: 140.00~(you can probably buy cheaper but I wanted something powerful) Source :Yet to be purchased
3)Arduino Uno: 35.00~(knockoff arduino would probably cut the price dramatically but your taking risks)Source : radio shack or ebay or amazon
4)Relay Board Shield : 20.00~Source : Radio shack ( at the moment mine is a seeed studio relay shield v1.3 )
5)Screw Shield : 15.00~ Source : I think it was ebay
6)Project Box: 5.00~ Source : Dollar General
7)Heatsink :10.00~ Source : Probably will be something in lowes
8)Wire : 8.00~ Source : Radio Shack
9)Perf Boards and screw connectors : 10.00~ Source : Alibaba express
10)Power Supply : 10.00~ Source : Yet to be purchased
11)Switch:3.00~ Source : Radio Shack
12)Extra Head Mount:2.00 each (I ordered 5 lol) Source:evilmadscientist.com
Total So far : $563.00~

Now this price may dramatically rise and lower all depending on what supplies you already have and what modification of the design you make.Example of this is that I already owned the arduino, the relay shield, the Screw shield, the wire , the perf board, and the switch and the water color bot because I didn't actually purchase the watercolorbot to make it into a laser which means I only spent $177 dollars more to build it.This supply list may change also for that im still working on this project.
