Unfortunately a lot of mid-range tables nowadays don't have the strobe (mine included), most likely for aesthetic reasons... Even just looking at online shopping right now I only see a handful that do have it.
As for being skeptical, good! That means I'm doing something great according to Clarke's third law.

The results aren't 100% perfect, and they definitely won't be as good as matching specific frequencies, but it'll get you very close to the ideal RPM.
- ssl-3 2y agoBuilding a "strobe" is just a matter of putting an LED, some diodes, a resistor, and (optionally) a transformer together. The idea is that the LED reaches peak brightness (and darkness) at twice the line frequency, just as ye olde fluorescent tubes did. (Or: Skip the extra diodes and have it work at 1x line frequency. I'm not your boss.) After that, just print a strobe disc and use it.

And working fluorescents (with magnetic ballasts that actually run at line frequency) are pretty much that way are too. LEDs and resistors, though? Bright, cheaper than chips, and ready for all kinds of modern digital shenanigans.
