Facelesstech made a light following bristle bot and wrote a post on his blog detailing its assembly:
Lets have a look at the hardware side of the build. Here is a bread board layout below. As you can see its just 2 bristle bots where the pager motor is controlled by a 2N7000 transistor which its speed is determined by the LDR (Light Dependent Resistors) and adjusted with a resistor trim pot. I also added a led to each one to show which pager motor is being activated, This makes it easier to see whats going on too.
Hardware list
- 2N7000 transistor
- LDR (Light Dependent Resistors
- Pager motor
- Resistor trim pot (10k omh)
- Switch
- Lipo Battery (3.7v 250mAh)
- Battery connector JST-DS female
- LED
- Resistor (220 ohm)
- Toothbrush
