Hello, i will show here how to made a portable case for raspberry Pi and video(cvbs) input. My first consept was to make this case for a portable TV tuner and video input. But two Pi was laying around and i thought one of them could be used for this project.
So, it is a portable Pi ,TV tuner with cvbs input, DVI-HDMI-VGA input and sound amplifier, with a keyboard and mouse ,all in one case with weight around 2,3 kilograms.
First step , is to connect Pi with controller broad and display , yes it is play ball together
If you own a laptop tft lcd ,you should find a compatible controller board for you lcd. There are lcd with 30 pins LVDS or 40 pins, those are not combatible each other. There are also newer lcd with led and older with inverter for lamps.If you buy from ebay , you ‘d ask the seller what is compatible with what, so i did .Remember you need some research before you buy , you start from what you have,lcd or controller.
I bought everything from the begging so it was a little easier,I choose a 15,6″ LED Display Full HD LP156WF1 Matte. Matte lcd is not so brightfull like glossy, but there is not any reflexion that is veryyy annoying for me.If you connect through hdmi ,better choose a 1080p lcd like this.
Controller. I use M.NT68676.2A controller board_V1.
Jumper must be for 3,3V AND NOT 5 v. It very important! Everything is in the photo below ,is included .Buy the board the cables and pcd for operation together, not separate.
You need also a 12v 3A power supply for controller board.
Now move to mounting . I use a plywood for lcd mount.
Two small pieces of stay ,for holding lcd case, don’t fall back
Now it’s time to mount the tft lcd display. I use an appropriate piece of aluminium and between this piece i bolt the pcb of the controller for controlling display.I use different ways to mount the display,but i think it is the best. Just use your imagination and use whatever around, better is aluminium because it is easy to use it and resilient
And a similar aluminium piece upper
Everything is ready, to place all things inside. I use another piece of plywood to bolt pcb .
I will get off scart and i ‘ll solder cables for video and audio for the tuner
Video and audio from tuner , will be input to a (cbvs to hdmi) converter. Output of the converter (hdmi) go to controller
Simple connections ans finished.
Here is tuner with cbvs to hdmi converter
And third and final, is controller board for display. Downside is power supply 12V 3Amps
I forgot to mention about sound. Controller does not has an amplifier,so i have to add an amplifier
