I wanted a machine that would turn on the torch on my phone when my finger was feeling tired. Here's the resulting "voice activated torch"
My daughter has been a youtube fan since she's been young and when she heard I was making a film offered to film it for "Megan TV" so it turned into a family project. As you might guess it took a few attempts to get it to run through to the end.
The stages of the machine are as follows:
- Google AIY - Voice activation
- Marty the Robot - Moves and flips switch
- Raspberry Pi Zero - Switch triggers a sweeping servo
- Toy train - Runs down slope and triggers microswitch
- Relays - Microswitch engages a two relays, one which latches and the other with starts a motor
- Motor with winch
- Lego pivot with touch pen
- Mobile phone with torch app
