Good news! The first prototype of my bowl feeder is ready! Finally I can do some tests and see how the mechanics are working!
It was an exciting moment to switch on the vibration for the first time, and to slowly increase the amplitude and try different frequencies. Unfortunately, the result was slightly disappointing: nothing happened.

The bowl feeder needs to vibrate with just the right frequency and amplitude in order to move the beads the optimal way. Since I don’t know the optimal parameters yet, I want to make a control circuit that allows me to tune frequency and amplitude of the vibration. In more technical terms this means I need two control knobs, two displays and a microcontroller for generating a PWM signal.
Continue reading “Bowl Feeder Control Circuit”As chance would have it, I find myself with a lot of spare time over the summer. This screams for a new project! Recently, I have made a list of skills I already possess and skills I would like to learn. So the project that I choose should help me learn a few of these.
After a lot of thinking I came up with the following: I want to make a machine that sorts my perler beads for me!

The basic idea of the weathermon project is to obtain, record and monitor the weather at my home. All weather data is sent from wireless sensors and then stored in a database, from which different graphs are generated that can be viewed on a PC, over the Internet and on a smartphone.
