The frequency range of this speaker is so bad that only a few typs of music sound bearable on it, including Kraftwerk and Aphex Twin

Now with the car audio apmplifier (I dont want to exceed 10W but this is so much fun)

Also available in dark theme

Book title is operation of traction vehicles

ET22 from the chart title https://en.m.wikipedia.org/wiki/PKP_class_ET22

If you ever needed, here is how to connect motors of an electric loco and the pull force [kG] vs speed chart [km/h] for each configuration. Top flat curve is traction limit

Throwback to when I was playing with a toshiba linear CCD and a spartan 6 FPGA. I should come back to it and make a slit camera

Testing something

One day I will collect them all

Dont say you are into signal processing if you don't know this track
