Why is there no arduino board (a really large board) that has all of the following. The board should also be able to control the power to all of these to save power.
I am sure they could actually make it the size of a match box. I don't think it would be that size with 3D printers though. Laser should also be added. Anyone want to design a PCB for this? I would actually buy one.
For everything there, you have an Arduino library available, you just need to search for them on Internet.
You can insert there a Sanguino microcontroller (ATmega644P/1284P), or you can modify the design for an ATmega328P micro, or even an Arduino UNO footprint and add your own components. You can do anything you imagine (including laser diodes and stepper drivers for a 3D printer).
The board is nothing else than a DIY enhanced replica to a commercial board, EvB4.3 made by a Polish company (And-Tech) who targeted the Polish Universities.
