Through a reverse-engineering effort it is possible to (ab)use a combination of cheap USB 3.2 HDMI video grabbers based on the Macrosilicon MS2130 in combination with small FPGA dev boards like the Sipeed Tang nano series (both ~10 USD each) to capture arbitrary data by connecting them via an HDMI cable. This can be used as a low cost, high speed logic analyzer, ADC capture, DIY SDR etc.
