Interesting! Can I control the frequency of blinking? Also can I limit the blinking only to the red color?
350ma to blink an led? That's some serious light. Please explain further.
The LED I have chosen is a Philips Lumiled LXM2-PH01-0070. The application is as an emergency stop light on race motorcycles. So I chose a bright LED - perhaps there might be a better tail light LED for this application?
Here is the spec sheet:

Still using the ADXL335? You don't mention it.
It is powered through AA batteries but my understanding of the 555 timer and caps was wrong. I thought the external battery charged the caps and the caps powered the LEDs and 555. Now I realize that the caps just regulate the 555, and do not power the LEDs...is that correct?
I am trying to replace the ADXL335 with a
tilt switch. I arrived to this idea after learning about the
mechanism that car airbag sensors use. On an inclination plane, the force of gravity is =1g*sin(theta). So if I want the switch to activate at a threshold acceleration value of .5g then a tilt switch which activates (closed circuit) at 30 degrees would work. I think it should work since I need to blink an LED at a threshold acceleration value - the actual acceleration value does not matter - if it exceeds the threshold, then I want to blink an LED.
Can you post a schematic and code of what you've done so far? That will provide detail for many things not explained in your post.
I have attached my code for my initial prototype. Basically the program self calibrates to zero the sensors and turns on the LED (pin 9) during that process. Then it blinks another LED (pin 13) if the acceleration in xyz axis is greater than .5g. I'd like to accomplish and replicate the same action/circuit with passive components. Sorry I don't have an actual schematic.
