24 I f you are having trouble figuring out the correct port, try unplugging, check the list, plug it back in, and then select
the port that was not there when it was unplugged.

27 T 27This interest stemmed from the fact we observed radical fluctuations in print quality using the open-source 3-D
printers discussed in Chapter 5 depending on the time of year and the equally radical (and sometimes uncomfortable)
environmental conditions in our laboratory.
28 T 28There is nothing in particular special about the polar bear other than it is cute and was the least expensive viable hu-
midiier solution we found during the time of the design. If it really is important to you and you do not like the polar
bear, you can make your humidifier look like anything else you can CAD using 3-D printing described in Chapter 5 .
29 A ll those normally opened pins are on a different relay each.
30 I if aesthetics are important to your lab, you can house the control board and wiring in a simple box that can sit on top
of your chamber. Similarly if you do not like the look of the bear, you can choose a different humidifier or box that as
well.
31 S ourceFourge.net is a free and open-source web-based source code repository. It provides fast downloads from the
largest open-source applications and software directory on the Internet.
32 T 32To do this, some understanding of C programming and the Arduino board are required.
33 I n addition, I would suggest that you copy the other part into the sketchbook, which makes it easier to open the ile,
and keeps your hard disk organized.
