For this weeks project I build two of the input devices, the temperature input and the synchronous detection board. I used fab modules to mill the boards and was able to solder on the components without difficulty. I first tried to use the boards on a mac, this did not go well, so I settled on linux. After a many operator errors I was able to run the make files. After a few more operator errors the computer said it was unable to find the port, after some online searching I discovered that the computer felt I did not have permission to run the program, someone else with this error posted the solution on a blog. After making this correction and plugging the black six pin cable in correctly the boards operated as they should. I have no clue what unit of measurement is being used on either board but they seem to operate and respond to various inputs.
