![]() ![]() ![]() Thank you for the link, I was sort of able to find his tutorial for a 20 inch Cinema Display but since it was an old mod the photo were no longer there. Why would you want to build in an external power source rather than use the stock power supply for the 23" Cinema Display? Considering it has an LCD controller already onboard and would just need to be wired up to a dvi port internally, you shouldn't even have to mess with the power supply at all. I believe the cinema has an LCD controller built in already that can be wired directly to a dvi connection. ![]() While I'm not expert, especially with the cinema displays, and hopefully jberg44 will eventually pop in. Also, why would you want to build in an external power source rather than use the stock power supply for the 23" Cinema Display? Considering it has an LCD controller already onboard and would just need to be wired up to a dvi port internally, you shouldn't even have to mess with the power supply at all. If anyone has tutorials and pin config for you to use during rewire, he will. I found what appears to be a pretty decent LCD controller on eBay that has hdmi/dvi/VGA/analog video input and audio out (which can be tied into the internal speakers of my g5 case it has it's own inverter and power supply, and though it's more of an easy way out, that may require some case modding, it has dazzle: while I'm not expert, especially with the cinema displays, and hopefully jberg44 will eventually pop in. A DVI to HDMI cable yields an HDMI out which plugs into the mini. One of the USB ports hooks up to the drive and one additional port is available for use in the rear of the machine. The cinema display's control board then sits underneath the drive getting power and signaling from the LCD and also supplying 2 powered USB ports. The 5.25" SATA DVD R/W drive slides in to where the native superdrive was and the SATA connected to the power and a SATA to USB converter. An on/off switch for the drive was added to the rear ports as well. The native iMac power plug gets split between these two. The cinema display's power brick is at the top of the dome with the power source from an internal optical drive enclosure. The neck has been modified with wires from the 17" iMac neck as well as wires from the apple cinema display's cable. The monitor housing contains the native LCD and inverter. This was originally an all-in-one which used a Penryn Core 2 Duo ECX board, however after difficulties with attempted hackintoshing and the release of the new Sandy Bridge mac mini's I elected to convert this to an external monitor for an external mini. The iMac G4's Apple Pro speakers connect via iFire to a firewire and 3.5mm jack to complete the setup. The iMac G5's iSight camera and microphone have been converted to USB making the iMac G5 an external webcam/mic. The iMac G4's base contains a DVD R/W drive - functioning as an external optical drive. Both the iMac G4 and iMac G5 are more than just monitors, they give the mac mini extra functionality. It is in a 3rd party mount that features very useful front facing USB ports. These are arranged in a dual monitor setup for the newest generation mac mini, which can be seen underneath the right hand portion of the desk. Both of these have been converted to external DVI monitors using a combination of native parts and parts from Apple's 20" aluminum cinema display. There is no need to cut away the Y junction.This is a case mod of two popular PowerPC iMacs the G4 and the G5. Do not connect the shields or the very fine red and black wires. To re-use these speakers, cut off the peculiar plug and wire on your own favourite kind(s). ![]() What is does is gives the computer the ability to detect that it is a genuine speaker plugged in and what kind of speaker it it (if there are different kinds). This chip is not connected to the speakers at all and has no effect on them. The logic chip is a Dallas DS2430A 256-Bit 1-Wire EEPROM. Starting with the tip and moving in the direction of the wire and finally outwards to the outer ring, the connections are:Ħ Black wire and all shields: Logic chip groundĪll the speaker wires pass straight through the Y junction with the same colour, and you can see the colours where they connect to the speakers looking through the back of the speaker spheres. But YES there is a logic chip in the Y junction! I did one thing wrong in wrecking the Y junction in that I no-longer know which are the R and L connections. I've read a fair bit of rubbish on forums about how these are digital speakers, or have an amplifier in them. I'm trying to re-use the speakers too, but I have an electronics background and not scared to pull things apart. ![]()
