Lets use a MacBook Pro early 2008 for our little Samsung DeX laptop project.
Looks roomy inside. Lets make more!
Lots of space to play around with.
Now for the waiting period of this project. We need to find an LCD controller board for this particular monitor. ebay to the rescue!
LCD controller board and backlight inverter arrived. DHL Express used a private jet I think.
Now for the fun part, we need to make this keyboard and trackpad work via USB. Lets bring out our soldering iron.
The 4 wire USB cable will need to connect, Ground, 5V0, R2 and DP. Success, we now have a working keyboard with a USB connector.
Next up. Fitting some batteries. These batteries is of type lithium polymer and was from an old laptop. However they where already showing signs of decay. Better now use them in a closed enclosure...
So I purchased two Power banks of the same type, and crossed my fingers the production date of the batteries matched. And lo and behold, they did! Slap those bad boys in parallel. 20000mAh, and 74Wh, plenty for around 4-5 hours of screen time.
Time for the lcd controller board, screen buttons and inverter to be fitted. Looks OK, but final reversion is better.
Maybe they will fit this way. Nope lets try again. The black box is the C-FORCE CF003 by the way.
Now we are getting somewhere, this looks OK. Note that I had to desolder the DVI, VGA, DC power, Audio in and Audio out plug from the lcd controller board for the height to fit.
2x XL6009 Step-up Power Module DC-DC Converter fitted, one for 12v and the other for 5v for fans and charging the phone while plugged in. Also added the 1A 5V Micro USB TP4056 Lithium Battery Power Charger Board Module TE420 for charging the batteries. And what will become the external USB plug. The 12v DC-DC gets hot as f***, so we need to find a way to cool it. I am happy I used very thick wire, as the inverter needs 4amp.
To my luck the original MacBook fan fits perfectly to cool down the DC-DC converter. Its the gray one in the bottom right.
Lets put it all together and see if it fits. I reused the original power plug for turning on and off the screen from the power button on the MacBook keyboard.
Isn't it lovely? I also found a magnetic micro usb charger cable for the charge wire. Can hardly tell it apart from a real MacBook Pro.
Next project. I need to see if I can fit this USB to Ethernet from StarTech. Should be possible.
