Τροφοδοτικά τι να τα κάνουμε- What to do with AC/DC power adapters

Показать описание
Κάθε τροφοδοτικό δίνει τα βολτ και βατ που αναγράφονται, και στο καλώδιο μπορούμε να βάλουμε λάμπες, η συσκευή με τα ανάλογα βολτ και βατ λίγο πάνω και λίγο κάτω δεν πειράζει

In this short video I demonstrate a few every day items you can power up, using AC/DC power adapters that you may have lying around or found in recycling bins.
These adapters usualy have a stable voltage output, and they allow you to turn a rechargeable device into a cord operated device. For instance, if you have a 4.5 V shaver, you can turn it into cord operated, by connecting a power adapter to it's battery leads inside.
That's exactly what I"ve done with a nose trimmer, where I used a small piece of wood, in the shape of a battery, where I've connected the two leads from the AC/DC adapter, the "+' and the "-" 4.5 volts. I connected the two leads in the two ends of the wood with a simple screw. Simple stuff.
You can also convert other devices, like old (or new) flash lights that use LEDs. Or you can make simple night lights to illuminate your house interior at night.
I made one using a 12V adapter, where I connected the bulb to the internal pcb, and I opened a hole on top to let the bulb protrude outside. This simple device can simply be bluged on the wall outlet and you're good to go.
The point I want to insist is that you don't need to open the adapters. These adapters use 220V AC power, and in case the internals are touched by human hands, they can cause damage or even death. That's why I open them up in my videos, so that you don't have to, and so that you can see what is inside.
Never ever open up one of these adapters.
You can use the cord that is comming out of the adapter.
In case you want to install a switch, the only thing you need to remember is that you just place the switch in one of the wires. Only one. You simply cut one of the wires, and you install the switch on that cut, so that the switch will control that specific wire. It doesn't matter which one, the plus or the minus wire, it just needs to cut one of them.
Each adapter has the output printed on top, so that you can decide where to use it. And you can use it either to power up a light or any other device that uses the voltage and wattage mentioned on the adapter. Small deviations are acceptable without a problem.
Of course, when working with electricity, always wear gloves and use the proper tools. Don't take unnecessary risks.
