well i think i will add another larger capacitor to the power legs on both the comparator and the timer. but other then that, most of these components are rated for 50v or more... and its all current limited so i dont see it being a problem.
i will find that out though, thats for sure. my parts should be here friday... also, the power filter coil i will be adding also has capacitance along with the coil itself.
