Well, time for another project to chew up whatever free time I have lately. This was a fun h/w interfacing project. Another GUI and DAQ setup really, this allows for rapid measurement and data acquisition though an HP4155C semiconductor parameter analyzer (SPA). The GUI is straightforward, and built to run on Linux (Slackware of course). This little tool has made automating and cataloguing measurements of diodes and dielectrics even quicker than ever before.
