As unbelievable as it may sound, you can use the Magic Trackpad on the Mac as a weighing scale to weigh stuff.
Developer Transforms Apple’s Trackpad into a Weighing Scale, and it’s Actually Quite Accurate too
Apple’s trackpad for the Mac is pressure-sensitive. If you press on it harder, you can invoke an action, such as finding the meaning to a word in a string of text. It’s quite genius.
Since the trackpad is pressure-sensitive, someone thought if it would be possible to use it as a weighing scale. Turns out, you can do just that.
Krish Shah on X demonstrates how the trackpad can be used to weigh stuff, and he even compares the trackpad’s performance to a real weighing scale too. The results are very surprising.
Interestingly, if you want to try it out for yourself as well and turn your trackpad into a weighing scale, Krish has shared his work on GitHub, which you can check out by going here.
Of course, you won’t be using your MacBook’s trackpad to actually weigh stuff. The idea behind this whole thing is to show that you can use the trackpad’s private API to track pressure and have it read as weight.
I know what you’re thinking right now. Just use an actual coffee weighing scale, don’t use your Mac’s trackpad.
