Bar End Brake Light: BEBL

Step 14 Improvement Ideas

Lower power, cheaper batteries, rechargeable batteries, Hub dynamo's.

Auto shutoff.  The schematic below show how the voltage regulator circuit could be modified to allow digital shutoff (for instance when the vibrations cease for a specified duration).

Use right angle header on GS1 and GS2.  This should still fit in bar and allow easy modification of Accel sensitivity.

Or better yet, connect GS1, GS2 to digital pins for digital gain control
I'll add this to the next version for sure.  No need for this project, but the design should be as flexible as possible.

Put long cord on slave board so that master can be installed easily on different bike
This is an obvious choice.  It'll be in the next version.

Use an independent pin to control slave LED.
There are plenty of pins on the MEGA, why double up on pin4 and loose independent control of the other LED?  I've played around with this, the extra logic slows down the tracking loop.

Next up ... a printed circuit board would make this a really fun and easy project.  Let me know if your interested.  I'd like to print up a few boards.
