Has anyone got a list of parts that could be bought from say CPC or RS or (even) Maplins!? Im interested in the cost of the parts and how available they are. Im thinking i might build one to improve my soldering skills then maybe sell my prebuilt one from Joel. ;-)

"It would be beneficial if someone can clarify this matter. I have noticed this company in the past. Debunk time?"

I have also been seeing their ads a lot recently.  They have been advertising in Nuts and Volts for a while, and I think Servo also.  I have also noticed that Fry's has started carrying their products in their stores.

It doesn't seem like an outrageous claim to me.  I can think of a couple of ways to do this.  The first would be to make a mask that would have pins that fit between the pins.  If solder does not stick to the material that the schmartboard is made from, but does stick to the solder pads, you can easily tin the board and chip.  Then you just hold the schmartboard in place and heat it.  Even better if the schmartboard has a highly heat conductive material with leads down to the pins.

I'm not saying that this is how they do it, but that is just one solution of the top of my head.  I'm sure with some thought, several solutions for hand soldering these parts could be worked out.  Particularly if the tools to do it were going to be made in large quantities.

Ok, I looked up their address, and found their PDF that explains how it works.  Basically it is a board that you solder your part to, so that you can add it to your project.  The description seems perfectly reasonable to me.

Does anyone know where one can buy the MCU?  I found it at digikey, but minimum order was 84 units.  I was kind of looking for one or two.

Yes, I'm thinking about building the minimig  :-)

Well but HOW do you solder it. Because you won't be getting the soldering iron between the chip and the pcb.

ThomasML:
Check Mouser.com, Maplin.co.uk ..?
Try google aswell. Sometimes it works.
Which country or continent do you live in?

Good question.  The next time I'm in a Fry's, I'll look and see if it is obvious from just looking at the board.  It will probably be a few weeks, as I don't live close to one anymore.

My impression when I got their brochure is that they sell mostly beginners kit and misc junk.
Seems my local branch doesn't have PIC18LF252, and they certainly don't have Xilinx stuff. My impression is that they suck.
Btw, their url of 1059 bytes doesn't impress me either.

Digikey have the PIC18:

They do. Reichelt or RS-Components are much cheaper. RS-Components has multiple stores in various countries (UK, Germany, etc.).

The way I understood it, all of the solder balls are on via holes, so you can solder it from the underside of the board.

Why dont they sell the PCB *WITH* components? It would be a great idea and save us loads of hassle. I would love to buy a pre-assembled Minimg, and a pcb WITH components would be my second option, but I dont see myself chasing components which I dont know even what they are for.

Because there is no "they"? The "they" you refer too is called Xenepp who will be buying and building them by hand :-D without charging for his time or skill judging by the prices he's asking.

I've PM'd him asking for one bare board and one assembled when he does another run of them. The bare board is so that with a friends help and the smt tutorials on sites like Make (etc) I can attempt building one myself.

I think a more sustainable model is by delivering a "kit" ie pcb + parts. This should also allow for lower prices, even if Xenepp took a small profit. That will allow people to concentrate on soldering. Some repair shops will do soldering work for pay aswell.
