Project Description

Have built a proto-type controller based upon an Arduino Mega. Made a MUX and DAC board providing screw terminals to the arduino and to external connections.

I made the boards from information gleamed from the net and using home PCB kits ....

I need the boards to be laid out so that I can now have several made for further proto-type proving and the help to code the use of them more efficiently. The MUX is standard with 16 inputs .... I am basically sensing 0..5V from signal conditioners. I would be interested in having a MUX designed to handle the connection from a J-Type thermocouple? So I can drop the signal conditioners?

The DAC is using SPI and allows me to output 0..10VDC so control some external hardware.

In addition, I would be interested in the boards being made, saving me time assessing where to get them made.

If this project proves to continue to be successful, I would like to eventually have a single board incoperating all the hardware, incluidng the Arduino, or maybe a different more powerful processor.
