When I was still in graduate school a few years ago, my office was in the center of a building which meant no windows and no way to quickly see the weather outside. This motivated me to make a project that would display the current weather on my desk. Being a pilot, I thought using the local METAR would be nice because I could also use the VFR, MVFR, IFR, and LIFR as quick designations for the weather and whether I could go flying after I was done for the day.
Although I really like the Kenwood TH-D74 for its long list of features, being an HT, the user interface is not well suited to satellite operations. In particular, for linear satellites where I may need to continuously vary the tuning throughout the pass, it is tough to come up with a good mounting scheme on my chest rig so that the tuning knob is accessible and the screen is viewable. To try to solve this problem, I thought I could somehow build an upward facing display so I can mount the radio vertically and have access to the knobs and a good display. The photo above shows the final product for this project which is built around a Raspberry Pi Zero W and the USB interface the TH-D74 supports.
