That bus pirate looks pretty cool. Its a bit weird for me looking at all of these programmers because I've never even had to think about it because the arduino has its own onboard. I want to start using more embedded systems soon though to save some money so I'll need to get a programmer at some point

If you already have an Arduino, you can use that as the programmer, by making up a programming cable and uploading the arduinoisp sletch.

The Bus Pirate is pretty cool, it replaces a lot of single purpose tools.  It can act as a programmer for PIC, AVR, and many brands of CPLD and PGAs; it also helps you debug i2c/TWI, SPI, CAN, and a bunch of other protocols.  Plus it's about the same price as a basic AVR ISP programmer, so IMHO it's a no-brainer.  It's also got a pretty big community of active developers behind it, so it will continue to be maintained and improved.

Yes, you can use an Arduino as an ISP, but it's a PITA.  You can also use a hammer to drive in a wood screw, but it's arguably the wrong tool for the job <g>

I have ordered 20 of my Mini-uino's. 5 10  15! are spoken for already (I can always order more). Anybody else wants a bare board, let me know.
$1.25 plus first class postage in a mail to your location (What's mail these days? 45-50 cents or something?)
Say flat $2, since I need to get a box of envelopes too.

how small is the chip? im not sure if my soldering is up to par?
I could print the Arduino logo on a box of cereal and sell it as "Arduin-O's"

Its the ATMega328P-AU. I made the pads a little thinner to give the solder mask a shot between pins and help avoid solder shorts between pins.
You're gonna want some flux and a small diameter tip to solder individual pins, ~.5mm, pads are .8mm apart.
Or a little bigger tip and do the "horizontal wipe" or the "drag" soldering you see on you tube videos.
I'm looking forward to trying those out.

All 20 Mini-uino PCB boards are now spoken for:
cyclegadget - 5
fxguy - 4
eddiea6987 - 5
kxtess5 -1
mabus - 5

I asked itead to bump the order to 50 pieces.
I ordered a set of these parts to build a couple for myself from Newark:
Newark Part No:  22pF cap
70K9277 Manufacturer Part No:
C0805C220J5GACTU

Newark Part No:  10K resistor
64K2889 Manufacturer Part No:
C0805C104J5RACTU

ABL-16.000MHZ-B2

Newark Part No: 100nF cap
26R4046 Manufacturer Part No:
CRCW080510K0FKEB

I have 0.025" square posts from other projects, you can get single row, double row, solder directly, male headers, female headers, your call for your project.

and the ATMega328P-AU that I purchased earlier.

Hey, looks like I have missed the boat but I'm certainly keen on buying a couple from you if you manage to get more stock  :smiley-mr-green:

Once you've made up an ISP cable for the Arduino and got it working, it's an entirely adequate tool for the job. But I agree that if you are going to be programming mcus frequently, a dedicated ISP makes sense.

I am not surprised, you have done a nice job on Bobuino board and this Mini-uino looks cool too!

We should all post what you end up doing with these boards. Mad props to crossRoads for organizing all of this btw

Thanks! Yes, would be interesting to what becomes of them all.
