Reid,  I feel that it's best to back up the 120AC.  Why?  For one of the reasons stated, it's easier to find many types of inverters because the 12VDC to 120VAC systems are made for cars and RVs.  There's

Awadelrahman,  There are a number of basic considerations to take into account, for instance:  1.  What kind of power consumption?  2.  How about voltages and logic levels.  3.  Do you need a controller

2007-08-08 LM3914 0-1V input:

Hi Floyd,  I believe that you should be using a PNP type transistor such as a 2n3906 for what you are trying to do.  The MJE3055 is an NPN power transistor.  Here is what to do.  Test it out on one LED

2007-08-03 DC to AC Inverters:

Sam,  If you are in the United States, we run of of 120 VAC.  So all of the equipment is designed for this voltage.  Just keep in mind the power requirements.  Speak to one of the customer service reps

2007-07-09 AES carrier voltage:

A long time ago, Philips had a chip that performed a similar function.  I don't remember the part number.  YOu may be able to go to the Philips webpage and look up audio ICs.  The chip that I used took
