Running a wired router from DC battery?
Locked
 
|
Okay, I've been thinking about this more, and maybe it would be worth trying to run our 4 port wired router from a battery, instead of using its AC-DCadapter, which creates a massive electric field (when I say massive, I mean I can measure it up to a foot away, versus other electronics where I haveto touch the meter to them to get a reading), and this travels along the Ethernet cable.
It's not picking it up from anything else; I tried plugging it in isolated from other equipment and the field was the same. Would it be easy to convert the router to run from a battery? It says on the back (and on the "Output" sticker on the AC-DC adapter): 5V DC, 2.0A This isn't a lot of energy, so I'm wondering if the electric field is so high because it's plugged into AC first. Do you think that using a battery for DC would eliminate or severely reduce the e-field? If you all think it's worth trying, I'd like to, but I have no idea how to go about it. Obviously the most common battery voltage with any worthwhilecapacity, short of rigging up one point something volt batteries, is a 12Vbattery, but that's too high. If I had a 12V source, could I use a simple, cheap linear regulator set for5V? I know that a linear regulator needs more volts, I think 3 or more (?)volts higher than what you actually want, so a 12V source would work...am I correct about this? If so, how would I actually go about hooking it all up? I'd still need a DC jack to go into the router, but don't want to cut off the existing one from the AC-DC adapter, in case this set up doesn't work. Any practical advice on how to do this, or if you think it'll make a difference? I'm guessing that Amps are nothing to worry about; the router would only draw what it needs, correct? Many thanks!

Interesting, I had built a power box with 2 toroidal transformers in it
to use to power my devices that needed power packs - The idea was to create a number of 12V DC outputs from it with a single rectifier, this being the best way to lower the EMF from multiple power packs in my office.. Of course I ended up using it on our Model Railway instead!
