Using MacBook's trackpad as digital weighing scale (github.com) 28 points by wtcactus 29 minutes ago

I think this is neat, but only in a Rube Goldberg machine sort of way. The instructions are:

1. Open the scale

2. Rest your finger on the trackpad

3. While mainting finger contact, put your object on the trackpad

4. Try and put as little pressure on the trackpad while still maintaining contact. This is the weight of your object

That is, the pressure sensors only work if it detects capacitance, so you need to be touching the track pad (but not too much!!) while weighing something. by hn_throwaway_99 0 minutes ago

There used to be iPhone apps that did something similar -

Very cool, but I'd still probably just buy a cheap digital scale. by ChrisMarshallNY 7 minutes ago

While imaginative, this is a recipe for disaster. Wait for people dropping liquid everywhere. by robthebrew 25 minutes ago
