Hard wire

**Lando** · 10-30-2003, 08:55 AM

My plan is to try to hardwire my remote control so I never have to change the batteries. Has anyone else done this? Any advice?

You mean you want to run 3 - 4.5 volts off a DC-DC power adapter wired to your remote control?

My advice is get the correct voltage adapter, and hook it up, you can either crack the case, or just wire it to where the batteries would go...

or be really tricky and make a couple of wood dowels, the same size as the batteries, put a thumbtack at one end of each, put the + wire attached to one thumbtack, and the - attached to another.

well the autoformatting here sucks but you get the idea

Kinda defeats the purpose of a "remote" control, doesn't it.

"remote" and "wireless" are not synonymous terms. There are plenty of situations where you want a remote that's wired. I personally think a car is one of those instances.

The easiest way would be a simple voltage regulator. You'll easily be able to find schematics online. Make sure you get the right voltage for your remote (1.5V per battery), and try to get a low-dropout regulator to reduce heat.

How does that help reduce heat then?

Low-dropout regulators don't produce as much heat, so he probably wouldn't have to sink it. That was the logic behind my statement.

Afaik, low drop out regulators just don't have as much head room requirement on input to output voltage. It is usually a term applied to linear regulators.

Afaik, linear regulators dissipation is always voltage dropped * current sourced, regardless of the low dropout specification.

You can get 5volts from the parallel port, ground one wire to the pc chassis or any metal object, eg: the metal that goes around the parallel port and another wire can be inserted into pin 1 from the parallel port. an extra .5 - 1 volts shouldnt hurt the remote. its worth a try though.
