I have a small B&W tv that I take camping. It runs on "D" batteries,
plug into car lighter, or on AC with an outlet transformer.
Next year when everything goes to digital tv, I may as well toss this
tv in the trash, unless I only use it where there is AC power.
Currently all the DTV converters are AC only. Maybe someone will come
out with a battery operated one in the future, but until then, has
anyone opened one of these converters and found if any can be run from
a battery? Almost all modern electronics step down the voltage and
rectify it to a low voltage DC, and I don't assume these converters
draw much power. Can any of them be modified to run on batteries or a
car 12v system?
If anyone modifies one, please post the info and schematics.
Yes, I know my battery operated tv will need external rabbit ears, or
a modification to the built in antenna so it exits with a coax long
enough to go to the converter.
How about going the other way and fetching yourself a 12VDC to 120VAC
inverter module. These plug into the likes of a cigarette lighter plug
and have
a 120 VAC outlet on the other end. Make sure to get the type that
produces
a step simulated sine wave output. These inverters are useless of
appliances
that tap into the 60Hz AC signal for timing purposes like some clocks
do.
