Akai ECV6607 TVout pc stats & psu mod

Primary LanguageC

Akai ECV6607 car DVD head unit on arduino /w TVout lib

  • Reuse old hardware for a fun mod.
  • PRO; Easy to use & free.
  • CON; screen resolution & CCFL backlight (energy efficiency).

The idea

Make a small low cost LCD/MCU(ATmega328P) solution that can display pc stats using USB serial. Reusing old e-waste parts. Add this to a SFF/mATX system with open side panel with acrylic glass from old LCD monitor.

First we wire the unit and run the stock demo:

Now we look at the simplified block diagram how it works:

Power supply default values IC902:

Example of IC902 (might slightly differ):

screendump IC902_2

WakeUP IC902 mod for always on (no standby), solder jumper between R939 and R959 next to IC902:

Wire up the TVout output from arduino to the unit:

Notes: TODO

Issue Solution
RM CCFL add LED BL off the shelf parts from CN
RM mainboard except display driver off the shelf parts from CN, more compact

Figure out what input the display driver likes remove HV parts retrofit CN parts. Make it Energy Star® compliance, get rid of obsolete fluorescent tube.
