Hello,

I would like to know what I need to buy exactly to build an open-source modchip that would work with a Wlip without having to solder it. More specifically, I would like to know:

1. The materials needed (with details please);
2. Where to buy them;
3. How to assemble them;
4. How to update the modchip once it's assembled.

Thank you!

Go to sample.microchip.com
Order 12f629 12f683 microchips. Get 3 of each. Make sure you get the I/P.
Get a jdm pic programmer off ebay.

Program the chip with YAOSM, Wiifree, openwii Wiinja. Whichever.
Plug into wlip.
Place Wlip on driveboard.

Its how I did the ones that im selling. Its also telling people how to do it for cheap that I havenot sold any.

I suggest you program it with yaosm. It's still in active development (unlike WiiFree for example, that one doesn't support SMG) and very shortly a completely new version of the software will be released.

I see a bunch of PIC programmers on eBay... Could you give me an example of which one I need to buy?

It doesn't have to be complicated, just be able to use 8 pin pic chips. I got one for $13 off ebay just yesterday, it even comes with one pic chip

Like this Programmer on Ebay

And if I had seen that before I ordered one yesterday, I would have gotten this like tomorrow and not have to wait till the end of this week or next week.

I use OpenWII. Their wiki tells you exactly what you need to build one. However, now you can order a kit from ebay (Atmega8l kit) that comes with everything you need. It costs about $17 total, that includes a Atmega Chip mounted on a PCB a programmer and the interface you solder in the Wii. It also comes with a Triwing screw driver to open the Wii.
The chip will need to be mounted on the outside but it works perfectly!

QUOTE said:
Also, it would cost me $24.62 just for the microchips, is this normal?
No. That's way too expensive. A single pic chip should cost about $1.50 or so

Forgot to say that it was including shipping to Canada ($13 shipping).

Also, why do I need 3 of each exactly?
And do I need wires or anything else?

With shipping that's still very expensive. It's just a very tiny chip. Go check out a local electronics store. They might have the chip too.
And you need only 1 of course. there are no wires required, the wlip takes care of everything. And you might need a cable to connect the programmer to your pc. And a tri-wring screw driver to open up the wii of course.

Why did Paul1991 tell me to buy 3 of each then?
What kind of cable do I need to connect the chip to the programmer?
After the chip is programmed with YAOSM, can I update it with a DVD?
If so, wouldn't it be easier to just buy a pre-programmed chip that I would update via DVD afterwards?

You plug the chip directly in the programmer. And the cable you need to connect the programmer to the computer. Which one depends on the programmer. There are USB-programmers and programmers that connect to your computer's serial port.
PIC chips can't be fully reprogrammed via a DVD. The new upcoming YAOSM has DVD partial upgrade support, but it can only upgrade a part of the chip. If a full reprogramming is needed, you'll have to use the programmer.

So if I buy a programmer that has a female end (with 9 holes), I can plug it directly into my P4P800SE without having to use a RS232 serial cable? See pic:

Yes, that should work. I can do that with my programmer too, but I still use a cable because it's a really tight fit if I plug it in directly.

Where did you guys find a programmer for $14 shipped? I can't find anything under $20... Perhaps you should post the auction number, as the links you gave me don't work.

I'm interested in purchasing a 12f683 pic chip with Yaosm 2.0 on it as programmers cost too much on eBay with shipping. Where would I find this? Or is this kind of question now allowed?

I think you should still have your own programmer if you want to update the chip afterwards.

By the way, I realized that you can order microchips for free using a university account on samples.microchip.com... I said it would cost me a lot because I had used a Hotmail address to register.
