This has been changed to a thread on creating DIY arduino's basicly. The new discussion is where to get parts to create an arduino.

why not make them your self, would save a smack load!!buying all the components is dirt cheap most expensive part will be the chips even that is cheap, a 328 is like 3.50

i build my uno clones for about 3 bucks.
I could print the Arduino logo on a box of cereal and sell it as "Arduin-O's"

Hello

yes those are fakes. The fact that you're asking here if these would work like the original shows that there is not other way to know than buying them. If they don't work you're stuck with them. If you buy from a decent source at least you can return them.

There are many cheap compatible boards (seedstudio is a good example and a good citizen of the open source hardware community) that there is no need to buy from these people who add nothing to the community.

I would never buy a fake board, if I knew it was fake, while they were claiming it was original.

However, I am mainly buying cheaper clones, where they clearly state it is a clone.

The hardware might be the same in the end, but I refuse to buy things from someone that tries to take advantage of someone else for their own good.

Can you afford not using any shields? I suggest BBB or RBBB from modern device. You can save up to 50% if you buy and RBBB. It has no TTL-USB converter and sits on breadboard like a little caterpillar. Easy to assemble and easy to power, program, and connect.

Recently I've taken to using the ardweeny.  This little 10 dollar machine is great for projects that don't actually need a shield.  You prototype them on a plug board and then move the entire thing to a proto board that will hold all the pieces.  Sure, you can get even cheaper, but I have found the fact that all the parts are supplied to me in a kit nice.  I've set these up with a wall wart power supply and ran them for weeks without a problem.  You can even put them on a socket so you can unplug, reprogram, test and then reinstall them.

Take a look, they may not be right for your project, but it certainly won't hurt to look.

Another don't-need-a-shield option: a real Teensy 2.0 for $16.

Well, you talk about this as if I'm rich... or an adult...

In reality, I'm 13 and have no real way to make money. Between allowance and side jobs, I make $80 a week.

A MEGA is $65. The mega board needs an onboard usb converter, so it pretty much has to be a MEGA, not a "MEGA pro" from sparkfun.

As for the other boards, they just need to have the chip, and the accessories that make it happy. A seeduino could work, but they're still $20 each.

I could build my own, but I can't build a mega. As for making uno's, the reason I shy away from that is because when I put the parts in a shopping cart, they were more than an original board... Maybe I'm doing it wrong?

Age doesn't matter much to saving money.  Sure, us big folk can waste more on prototyping expenses, but when it gets down to building it, money is always a factor.  That's why I use ardweenys a lot.  I even build my own XBee interfaces and try desperately to keep the cost down on various projects.

I have an arduino for prototyping and then convert it to something else once it's working.  Gotta keep that arduino free for the next project.  Keep at it, consider possibilities that aren't obvious.  One can even solder all the parts directly on the chip to save the expense of a circuit board. 

Unos aren't all THAT cool.  The older models had a lot going for them.

Could always fake your way into a Mega:
Schmartboard $10
ATmega2560  $12.86

(shop around)
xtal, 22 pf caps, 100nF caps, 10K resistor - <$1, dip micro.com
header pins - depends on your needs.
Learning experience: priceless.

It might help to know what you need them for. You might get away with 7 ATmega chips on a breadboard with a Teensy++ 2.0 and a handful of cheap parts, and you might not.

It's a permanent project, not a temporary thing. It's gotta be solderable, or header-able... As in an arduino clone with perf board on top so I can disconnect it.

As for that DIY mega thing, my soldering iron sucks. I would probably break many of those chips. For the MEGA, I might just get a legit board, considering it has all the parts needed to make it work, and on board usb conversion.

If someone can tell me the best place to buy parts to make an arduino, I will probably do it myself. I'm bad at picking parts, so it was more expensive than it should have been when I tried. So if someone can make me a list of parts, that would be great.

My suggestion is to get the RBBB PCB only from Modern Devices:

http://shop.moderndevice.com/products/rbbb-pcb
For 10 pieces, the PCB is $1.95.

Then source the parts from Digikey, Mouser, .....
ATMega328P-PU from Mouser is $3.31 per piece at 10 pieces.
The rest of the parts are pretty cheap and probably add another $1 per board for that.
Also check out Dipmicro for cheaper supporting parts & components.

Jeremy1998

So this RBBB thing... Do you recommend that I get the PCB's, and buy the parts elsewhere, or buy the whole kit for $110 ($11 each)?

CrossRoads

$11 each is not bad!
Price up getting all the bits yourself from DIPmicro,
xtal,
22 pc caps,
100nF caps,
sockets,
power jacks,
LED,
resistors (LED and reset),
reset switch,
regulators,
10 uF caps,
headers.

FTDI Breakout board
http://store.nkcelectronics.com/breakout-board-for-ft232rl-usb-to-ser232.html
that you can use to download bootloaders and then sketches

and blank '328s's from mouser/newark/digikey,
3.49/10 @ newark
3.12/25 @ digikey (1 for 4.98)
3.31/10 @ mouser

and shipping from 3 places.

Price it up, see how it works out. Maybe DIY is the way to go.
