|Original Dual Monitors with Mac Mini|
|New Setup with iSight G5, Mac Mini, and iPad|
Personally, it has become difficult for me to use LCDs under 19" as I've become so accustomed to larger displays. The 20" iMac is a sizable display as is, but several factors actually make the screen bigger than most 20" displays. For one, the aspect ratio is 16:10 not 16:9, for 20" this makes a substantial difference (1680x1050 vs 1600x900) in the overall size and pixel density. Plus, the nature of the iMac G4 itself allows you to pull the display much closer to you than an ordinary LCD would sit. Even still, to be a workstation, I feel multiple monitors are invaluable. I got fortunate in "spare parts" that I was able to put the iMac G5 (native LCD, Apple Cinema Display's controller, inverter, and power source) together very quickly. However, there are multiple ways to "resurrect" an iMac G5 as an external monitor depending on available parts. The effect of having both together is great. The iMac G5 is also quite ergonomic, in both its sliding and tilting.
I originally concealed this in the inner part of the desk, but the I bought a great under desk mount with 4 front facing powered USB ports.
This is actually DC powered, so I used a power source from a broken internal drive enclosure. I use the original iMac G4's AC plug, but split it, with one going to the cinema displays power brick and one going to the drive. Thus, only one AC plug and no external power brick is required.
|Rear Ports (USB Out, Drive Switch, AC Power)|
The rear panel contains the original 3 pronged receptacle for AC power, an on/off switch for the drive, a USB out, the outgoing USB cable and HDMI cable. The USB cable belongs to the cinema displays controller which then supplies 2 ports. One is taken up by the drive internally, the other is on the back (hooked up to the camera here). So, by having the drive plugged in, you essentially replace the used USB port.
There is a quirk with the DVD drive. When there is no media in the drive, the keyboard eject shortcuts do not work and you can not access the front button on the drive. To eject the drive you have to open disk utility, click on the drive and press open. Now by putting Disk Utility in the dock, opening the drive takes only 3 clicks, however, this is somewhat of a nuisance. When media is in the drive this does not seem to be a problem.
SOLVED - thanks to fellow modder and iMac enthusiast Jean Luc, I now have an eject icon in the upper right corner, that allows me to easily eject and close the drive in the G4's dome.
This works flawlessly. It eliminates a flaw of the mini and gives purpose to the base of the iMac G4.
Besides cleaning up a few of the rear ports, this iMac G4 mod is complete and perfect in this setup. This is largely the same mod as before without the all in one.
|Side/Rear iMac G5 (1st Generation) Mod|
UPDATED - with advise from Jean Luc and research I have realized that there is a considerable difference between the original iMac G5 (1st Generation)and the iSight iMac G5 (3rd Generation - much thinner, and with iSight camera/mic). I am going to attempt to transfer the contents from this G5 to an empty chassis from an iSight G5. I believe this will likely fit this mod better. As I have stated much of the iMac G5's shell is currently wasted space, having a smaller, sleeker chassis would likely look better and save some desk space. Although much tighter, the only contents that will need to fit are the Cinema Display's LCD controller and inverter . In addition, as Jean Luc explains in the comments below, the iSight is simply a USB device. With addition of either a USB adapter for the microphone, I can connect these to the Apple Cinema Display's USB ports. As this leaves only 2 Firewire 400 ports, I would likely either hold off on adding the rear ports to see if my "thunderbolt dock" idea becomes feasible, or use a firewire to usb dock to add USB ports to the rear of the iMac G5. The RAM access panel at the bottom may also let me bring back the Cinema Displays hardware touch power and brightness controls to the bottom of the display.
FURTHER UPDATED - I have indeed used JLs advise and the chassis of the iSight G5 complete with original microphone and iSight Camera. Please see this post on the iMac G5 iSight for details.
In general this is even beyond the setup that I envisioned as a best case scenario when I began this project.
Suggestions are appreciated. And if there is interest I'd be happy to provide technical details. Thank you for reading!
It's always a great pleasure to read your blog. Seems we are working on similar projects: Mine is a 17" G5 housing meant to be an external monitor with an WUXGA display (1920x1200!), touch display, self-powered USB and some internal USB add-ons like USB Sound (to take advantage of the internal mic) and of course the built-in iSight.
Two possible hints for you:
1) Under "/Macintosh HD/System/Library/CoreServices/Menu Extras" you find a small program called "Eject.menu". If you double click it, a small eject icon will appear in the status menu on the right upper corner. In my case it shows a menu with all ejectable drives and allows to open or to close their drive doors. Maybe that helps with the closed iMac G4 door.
2) The built-in G5 iSight first was a mistery to me. Apparently it used a FireWire-400 4-pin connector, but without any power supply. And of course it did not work with a FireWire-400 Cable. After I removed the isolation I found the reason why. Actually it is an USB device, showing the common black-green-white-red wires. After I soldered them to a standard USB plug, everything was ok and now I have a USB Built-in G5 iSight at the top of my new HD monitor.
JeanLuc, again thank you so much for the tip. The eject option works like a charm. Having to go into disk utility every time to open up the drive was not something I found appealing, the eject option in the status menu is an elegant solution. Thank you!ReplyDelete
Thank you for the tip with the iSight as well. I feel as though, as the computer is external, I want the iMac G4 and G5 housing to "do something". By having the drive in the G4s base, I feel like it now has purpose. Likewise use of the iSight in the G5 would accomplish something similar. Unfortunately, the empty are I had chose was from a first generation iMac G5, the iSight G5 (the 3rd generation) actually uses a very different case. There are some advantages of this, as it is quite thinner and will take up less room. Unfortunately, I will have to try to find a clean G5 iSight housing now.
I do have a question regarding the microphone you mentioned. If I remember correctly the microphone was located at the bottom of the case right? or is it past of the isight board? And it is also USB compatible? Thanks again, Jon
Good to hear that eject issue is solved.
Actually in the "iSight G5" the microphone sits next to the iSight camera on top of the display, but it is not connected to the board. It is a standard electret microphone with only two cables and a shield - quite the same as in the iMac G4. That's why I decided to use a USB sound stick and connected the microphone to its input plug. Hint: the really cheap sound sticks do not work properly (much noise). I took one which was sold as "Mac compatible" for about 20$ and it works like a charm.
In your posting I was wondering when you mentioned that much space in the G5 housing, but now I see your "G5 1st Gen" is considerably thicker than mine. Still I have some trouble with the TFT controller for my WUXGA panel, which does not work correctly with the panel. They will send my a programmer board - seems they do not have the right parameters for the panel's LVDS input there.
I also had to give up the idea of touch-enabling the panel. Yesterday the touch panel arrived from Singapure and it actually is a 5 by 4 panel for 1280x1024 screens (my fault). Seems my next project is about a 17" Studio Display ;-)
Great write up. I have an 20" iMAC 1.8G that has finally died after 6+years of service. I am sure that the logic board has gone...again. My plan is to get the Mac Mini server, remove the super drive and place it in the OWC super thin enclosure and would like to make use of my 20" screen. My question is this, what do I need to do to be able to plug this iMAC into a Mac Mini? As you had mentioned above, to be able to use the ports on the back of the iMAC like a hub would be the "Icing on the cake!!" Any information would be great. I want to reuse what I can if at all possible.ReplyDelete
D.Zack, I assume you are talking about the iMac G5. Most of my so far has been with the iMac G4. The way I created this mod was using the logic board and inverter from the 20" aluminum apple cinema display. In my new version of this mod this is extremely useful as the apple cinema display's logic board has USB connectors. This allowed me to use the iSight camera and microphone. One of my newer posts details this. Hope this helps.ReplyDelete
Would you happen to have a specific pinout for the inverter and/or pwr supply on a 20" 2nd Gen iMac? (EMC 2056).ReplyDelete
I want to use the LCD as a VGA or DVI monitor. But I'm not sure how to connect the original power supply to the inverter OR which wires to splice the LDVS cable to a VGA or DVI cable.
I'm afraid to attempt this without knowing, and then blowing my only inverter :/
jdisco, I'm not sure if I replied to you or not, but this iMac G5 is TMDS compliant and you should be able to use the pinout I list on my blog for the iMac G4 20" Make sure your panel is one that I list in this post as being TMDS compliant.Delete
Nice modding. I've seen your work since you've made the first iMac g4. I tried to do the same but failed with burning the lcd of the iMac. Right now i have a iMac g5 with a toasted motherboard and i am trying to get a mini inside, with psi and all.ReplyDelete
I know I have managed to power up the lcd with the original psu of the iMac but i lack the schematics for the ldvs to dvi/vga.
I want to use the LCD in the iMac, because i consider to be a waste to buy another monitor.
If i find the wiring diagram i'll also post is here.
I've burned out plenty of lcds, inverters, etc. Remember, some of this stuff is over a decade old. Things can burn out and may not even be your fault. That said, the 17" and 20" iMac G5 panels are interchangeable in the iMac G4, so you should just be able to use the pinouts I have listed. Of course you should use the pin number and not the wire color. The panels are TMDS. See this post for details on which panels are TMDS:Delete
I bought a 4 port usb hub and connected it to my imac 20"g4 immediately the hub burnt out and has burnt out all 3 of my usb ports can someone please tell me how/why this has happenedReplyDelete
