How to build a multi LED blink circuit triggered by vibration sensor?
Here is the completed solution:

The monostable 555 timer is triggered by the vibration sensor. The output of the monostable timer is connected to the transistor base with a 100k resistor. The transistor closes the circuit (negative side) for the astable 555 timer and the decade timer. The astable timer runs the pulse for the decade timer then when the duration is over it shuts off. The Potentiometers control how long the duration (Monostable Timer) and pulse (Decade Timer) will be.

This was the second completed circuit. The first one didn't work properly so I don't think I soldered it correctly and started from scratch. I mounted this to a small scooter but once weight was put on the scooter it didn't work properly. 

I also made a Arduino nano version using the vibration sensor to trigger 17 LEDs. Once the sensor was triggered it ran a knight rider LED sequence which worked great but doesn't seem to be battery friendly. Currently I'm trying to figure out how to integrate a sleep and trigger to help with battery consumption.

I'm still quite new to all this and it really tested my soldering skills. I tried to have the monostable timer directly trigger the astable timer but one LED always stayed on and I didn't know how to have the decade timer turn off. I was thinking that I might have to put the whole circuit in epoxy in order for it to work when pressure is applied to it or not use ic sockets. I do like how it came out but I'd like to make this much better.
