A 150-Picosecond TDR Sampler for Under $2

One of the most enjoyable parts of electronics design is getting excellent performance with rock-bottom parts cost.  The right circuit can produce exceptionally good speed, noise, and accuracy specs from very low-cost parts.  A case in point was a project from December 2016: a time-domain reflectometer (TDR) for a liquid level sensing application in industry.
