As a first power supply, I would scrounge up an old ATX power supply and then get a handful of those switching regulators on eBay for a few bucks.  They're $12 for 10, shipped from the US.  That'll get you from 12V all the way down to 1.25V, at about 1A per regulator.  That should be plenty for a beginner.

Or, maybe $12 is a bit steep for an 11yo, you can go mow some yards and then head on over to the Radio Shack for an LM317 adjustable regulator, or some 7805 fixed regulators.

You're going to need some breadboards and jumper wire; use Ethernet cable for jumper wire, it's really cheap and lots of people have cables that have stopped working.

I got your PM; you're too far away for me to drive it to you, and shipping is murder on things this heavy.  I think mowing some grass or something and earning your stuff would do you better in the long run, anyway.

Hi Hunor,

Are You an expert in all kind of Arduino things ??

This could be a very good beginning.

I have A few 7805s.

And 12USD in not that expensive.

Yeah, I play Minecraft!
But I'm on here more because I learn more. :D

I have an arduino but I barely know how to make an l.e.d blink. :palm:

Then, this tutorial could be useful for You...

Enjoy, and maybe in 4 years You will be an expert like Angelo ( http://ascas.tk/about )

You should do some arduino stuff.  Learn to talk over i2c and spi and serial.  Blink an LED. Fade an LED according to some analog or digital input.

Have fun.

Never give up.

Well I know how to open a sketch. :D :P

+1 for the LM317s (or low drop-out equivalents) but you may need some heatsinks too, and +1 for the the cheap Ebay switching regulators, but it might be handier to get different types e.g. a few step-up (boost converter) modules, a few step-down (buck converter) modules, and a few combination auto step-up step-down modules.
Nothing is quite like a great humming power-station.

With LM317s you'll want some 25uF electrolytics on the output, a 0.1uF NP0 ceramic for the input and another for the adjust pin (or a 5-10uF tantalum if you dare).

But a box of 0.1uF and some electrolytics in the 25uF-100uF would do you well.
To be responsible, but never to let fear stop the imagination.
