to mark as completed Tiny Tin
Tiny Tin is a cute little bot in an Altoid tin. I built him just before World Maker Faire New York in 2014, but never documented him or posted much about it.
Tiny Tin is driven by four continuous rotation servos, with double ended servo horns acting as legs/wheels.
One very tiny 3g servo is used to raise and lower his lid.
He currently has no sensors, but he has expressive LED eyes that are only visible when he lifts his tin lid.
Update: 2017-Jan-07
Desoldered the old Arduino Mini Pro clone and custom circuit board, and soldered in the Lilypad Mini Simple. It works, but I'll need to re-do the wiring to get everything to fit better.
Update: 2016-Dec-29
I'm reviving the project, starting with a brain transplant from a Arduino Mini Pro to a Lilypad Arduino Simple.
The Lilypad fits the Altoid tin with room to spare. I hope to solder the wires from the servos and such directly to the large solder holes on the Lilypad, and avoid the need for an additional circuit board. The Lily pad also has its own power switch, and a JST connector for the Li-Ion batteries I use.
Walks around, lifts lid, blinks; currently random behavior.
- Actuators / output devices: 5 servos
- CPU: Lilypad Arduino Simple
- Power source: 3.7V LiPo Cell
- Sensors / input devices: none (yet)
- Target environment: Floors and table tops
