Introduction: Simple Power Adaptor for Arduino

Here is a simple and cheap way to get your arduino power.

This instructable only use "three things" and can be finished ~1 minute :-

1. power connector (for Arduino Uno, it is 2.1mm power connector)

https://www.arduino.cc/en/Main/ArduinoBoardUno

2. "2-pins" terminal block

3. solders

Although I want to write something, but it seems u can understand by viewing the photo.

1. unscrew the power connector and bend it (as photo shown).

2. shorten 1 pin of the terminal block

3. solder them

U can now easily power your arduino...

Cheers

Step 1: About the Plastic Part of the Power Connector.

From this instructable, the plastic part of the power connector was left.

This plastic can be used as 5mm LED cap which shown on the photo.

Your idea... simple AND awesome. Those are the best. Thanks!

You got my vote kokpat.

Elegant in its simplicity. The black plastic piece you have leftover may be useful in a future project. Good job.

Yes, the black plastic holder can be used as shield for LED.

comes in male too:

but thats a great hack for non standard sizes, could i suggest maybe a little heat glue to prevent shorts and increase mechanical strength?

How about using putty (plastic model) ?

It can be easily filed or paint after dry.

This is awesome! You should enter the 3 things contest!

Thanks you very much.

I had applied the 3 things contest after u notice me.
I don't know whether I am eligible or not, first I think I use just two things, but after I think I had used 3 things...
i.e. a power connector, terminal block and some solders.

Genius simplicity! Thank you for sharing this idea, I can't believe I haven't thought of something like this!

Good at you.

Wouldn't it be simpler to connect the battery connector wires to the power connector? The terminal block isn't needed.

author
kokpat (author)BrianEV2015-11-26

=^.^=
That's okay, sometimes I directly solder the wire on Arduino.
But as I made it, it means I need the terminal block. Just say get power from breadboard.

Whats the size of the power connecter?

author

I have no idea what that green thing is, or how to obtain any of the parts. A few words might be helpful.

author
kokpat (author)algelman2015-11-26

The green thing is called "terminal block".

But I think they might have various name, so, it is only a reference…

The metal thing called "power connector" which commonly found with transformer (notebook computer...)

This is AWESOME! I can do the same thing for many other electronic projects.

Gelfling6 (author)2015-11-25

Nicely done!!! My option for Perf-board projects, especially when using a semi-modified ATX to Bench Supply, is I leave one drive power cable connected, with the mini-Molex for 3.5" drives on the end. and simply reuse a power connector from a dead 3.5" floppy drive to provide +5, 2 GND and +12 to the board.

Sometimes the most simplest of ideas are the best. This just one if those really good ones. Surprised a manufacturer has not made one to sell at £stupid. Well done.

Hey. That is clever! I am going to have to go make one right now.

This is one of those rare hacks that really should be manufactured by someone, it's simply brilliant!
