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.

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
Newark Part No: 16 MHz xtal 13J1628 Manufacturer Part No: 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. Newark Part Number: 14R4631 Manufacturer Part No: ATMEGA328P-AU

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

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>
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! Mark
