The Completely Hackable Amateur Radio Telescope (CHART) is a radio astronomy platform aimed at high school students and teachers. The project offers online tutorials and code for building an inexpensive instrument to detect the 21-cm signal from neutral hydrogen in the Milky Way. Complete parts for the project can be acquired for under $300. The base platform is intended to work out of the box for this experiment, but is easily reconfigurable for other parts and applications. The spectrometer uses the RTL-SDR module and a custom GNURadio application which can be operated via a python-based GUI. Users analyze data in jupyter notebooks. Template code is available for flagging, calibration, plotting, and similar functions.
