Sonic toothbrush hacking moding

Postby Zak_Mak » Wed Nov 13, 2013 10:25 am

I need help with Sonic toothbrush hacking

I am wondering if any of the experts here could answer any of these questions with the limited information that I can provide

Information that I have:

The Philips toothbrush has a two minutes turn off timer!

a 30 second quad spacer (brief pause of vibration) every 30 seconds

The pcb has a TI MSP430G2412 microcontroller ( http://www.ti.com/product/msp430g2412 ) with the additional markings of “ 21K G4 “ and “ AS&F A ” on it.

It drives an electromagnet that consists of two coils, at approximately 1 KHz

Most of this and some more is visible on the pictures of the pcb and the assembly that I included.

My QUESTIONS are:

1, What is the easiest way to disable or change the 2 min power off timer??

(I very much would prefer not to reprogram or to replace the microcontroller, but if there is no other way than )

2, Is it possible to reprogram this specific controller and if yes is it possible to do so without disordering it?

I know it is a long shot, but I hope that one of you creative people can help me with a solution.
Thank you very much for your time spent thinking about this!
