Hack a Day Classifieds really work!

Well, the DIY-intosh sold! I bet you're all rejoicing that I won't be trying to pawn off my stuff on you for a while. It's really amazing how it sold within a few days of listing it.

In other news, I fixed up a 19" 4:3 aspect ratio VGA monitor with composite, coax TV, and SCART inputs (it's some Samsung 910-something). It only needed 6 capacitors replaced, totaling $3.40 + $2 shipping (or something like that). Seeing as I bought the thing for $17, this makes it a steal. It also only has one grey pixel! This is why I work with hardware!

Sorry about the server downtime! That was ratherĀ embarrassing...

Anyone interested in buying the DIY-intosh?

Well, I kinda want to buy a more portable Mac (an older 17" MacBook Pro), so I'm going to be selling this for $400. Why $400? Well, I actually built it for just over $300 and similar Macs are over that price. It's really great at running a MakerBot, and it's good for iPhone development, too.

Specs:

  • 2.0 GHz Intel Core Duo Processor
  • 2 GB of DDR2 667 MHz RAM
  • Bluetooth
  • Wireless N networking
  • 100 GB 7200 RPM SATA HDD
  • 2 USB ports
  • 1 Firewire 400 port
  • 1 Mini-DVI port
  • Mic In and Audio Out ports
  • 10/100 Ethernet port
  • Magsafe power connector
  • OS X Snow Leopard pre-installed

What it will come with in the box:

  • DIY-intosh
  • A 60W MagSafe PSU
  • OS X Snow Leopard Disk
  • A Mini-DVI to DVI Adapter
  • A Mini-DVI to HDMI Adapter (video only)

Note #1: The DIY-intosh does not have a DVD drive. You can, however purchase a USB DVD drive if you need that capability. You can also enable Remote Disk on the DIY-intosh (search Google for the terminal commands). I suggest that once you have recieved the DIY-intosh that you enable Remote Disk and make a DMG of the install DVD. Then, you can restore that DMG to an 8 GB USB drive. In the event you need to install OS X again, you can just boot off of that USB drive.

Note #2: I don't ship overseas. It's just too expensive.

Email me ASAP if you're interested (click on the "Contact Me" page to see my email address). If many people email me with serious interest, I'll put it on ebay, otherwise I'll just use SellSimply. I must recieve at least one email with serious interest before I put it on either site.

MacBook Core Duo Logic Board Keyboard Connector Pinout

connector

Well, I did some testing, and I found out that the connector for the Core Duo MacBook leopard connector is really just a USB port. Also, after pouring over a datasheet, I found that the two PSoC's on the leopard's board are connected over an I2C bus and then the one labeled "B" is the one with the USB connection to the logic board. The one labeled "A" is the leopard controller.

With this newfound information, in theory, I could make that internal USB port external, giving my DIY-intosh an extra USB port to work with. In practice, those leads are just too small to solder.

Also using this information, I attempted to turn a MacBook leopard and trackpad into a USB leopard and trackpad, but as I soldered the D+ and D- connections to the test points, the stress on one of the points broke it off. I also lost one of the SMT resistors after I tried to solder to it (after I broke off the test point). I can plug it in to a computer, but it is not recognized. I haven't tried plugging it into a Mac yet, so it may just be a driver issue.

Please use and expand on this information! I've already reduced by $10 the value of a $25 leopard assembly (I <3 ebay), I want to know if I can make an external MacBook leopard + trackpad before I drop $50 on another one!

I sent this info to http://pinouts.ru/ so that others can benefit from this.

Edit (4/17/2013): Pinouts.ru seems to be defunct/compromised, but I found a link to another pinouts website that seems to have mirrored the pinouts.ru page. http://pinoutsguide.com/Inputs/apple_macbook_keyboard_pinout.shtml

How-to: Build Your Own DIY-intosh

Well, I think it's about time that I made more of a how-to to build a DIY-intosh.

There are plenty of how-to's to make Hackintoshes, but those are teetering on the edge of legality, are difficult to get as stable as a store-bought Mac, and OS updates can't always be installed without any mods. Macs are supposed to be reliably stable—that's one of their main selling points; when you remove that stability, you remove a major component of the Mac. The only reasons you would want to build a Hackintosh is to have a really powerful Mac Pro at a really good cost, to have an OS X netbook, or to have a really inexpensive Mac Mini.

The DIY-intosh can be built as a really inexpensive (mine was around $300) yet still Apple-reliable Mac. Here's how to make one of your own:
