One of the greatest features of the opensource hardware community is the abundance of resources we can use in designing new hardware. In the T400 temperature datalogger we extensively used parts from other opensource companies. We also made several Eagle parts of our own too, including those for our custom thermocouple connector and 132x64 LCD. We've posted our Eagle files on Github. If you use any Pax Instruments parts, we'd love for you to link to your project in the comments below.
