Description

This gadget is ment as an alternative to the tennis-ball-meets-bumper type of parking aids.

The parking sensor blinks green on approach (<150 cms) and will blink faster and faster as the distance is closed. When the target distance is reached (10 cm) it changes to a solid red to indicate this. Finally, then the measured distance stops changing, the parking sensor will stop blinking.

As you surely can see, this is still very much a work in progress. None the less, if supplied with permanent power from an outlet, it could be used as is. Running from batteries won't last long at the moment.
Possible power usage improvements include:
- Reducing duty cycle
- Wake only when car approaching
- Use switching mode regulator instead of linear regulator
Other improvements would be a custom PBC and a custom casing.
