If you can't find answers in the Frequently Asked Questions or Tech Bulletins sections of this web site then e-mail your questions to the address below.  This e-mail is only for astronomy related questions about the DewBuster™ controller or home-made heater strips, non-astronomy questions will be ignored. The home-made heater strips will only work with a telescope heater controller and I will offer no advice on modifying them (try searching the internet for alternate plans).
