    Messing with old computers always makes me want to make tiny desktop apps. Can you imagine programs that do useful stuff measured in kilobytes? 1985 could. They didn't make a computer big enough to load an Electron application until something like a dozen years ago (some might argue they still don't make a computer big enough for Electron applications).

    100-Year Old Wagon Wheel Becomes DynamometerIf you want to dyno test your tuner car, you can probably find a couple of good facilities in any nearby major city. If you want to do similar testing at a smaller scale, though, you might find itโ€™s easier to build your own rig, like [Lou] did.[Louโ€™s] dynamometer is every bit a DIY project, relying on a 100-year-old wagon wheel as the flywheel installed in a simple frame cobbled together from 6ร—6 timber beams. As you might imagine, a rusty old wagon wheel probably wouldnโ€™t be in great condition, and that was entirely true here. [Lou] put in the work to balance it up with some added weights, before measuring its inertia with a simple falling weight test. The wheel is driven via a chain with a 7:1 gear reduction to avoid spinning it too quickly. Logging the data is a unit from BlackBoxDyno, which uses hall effect sensors to measure engine RPM and flywheel RPM. With this data and a simple calibration, itโ€™s possible to calculate the torque and horsepower of a small engine hooked up to the flywheel.Few of us are bench testing our lawnmowers for the ultimate performance, but if you are, a build like this could really come in handy. Weโ€™ve seen other dyno builds before, too. Video after the break.youtube.com/embed/61-e-HK6HdU?โ€ฆhackaday.com/2025/10/30/100-yeโ€ฆ

    @BathysphereHat not sure! We'll see how the spirit moves me. We have a big costume box and I usually throw together something from there.
