Woodblock & Packr
As someone who loves to travel by bike and as a hobbyist cook, I got two passions that require measuring things by weight. Especially on long bike trips, it really pays off to keep an eye on the total weight of your equipment – at least you have to move everything by the force of your muscles. So I decided to build my own wireless scale, that can be uses in combination with a computer or a smartphone.
The scale, called Woodblock, was built by combining conventional components from an ordinary kitchen scale with an Arduino board and a Bluetooth chip. It is complemented by the app Packr, which receives data from scale via a wireless connection to display the current load on a smartphone.
