Having too much fun with the Tivax STB-T9. Feeling lazy but will add more details later here is what I’ve done so far.

Noticed unpopulated usb port on the front panel. 4 pins same as uart

Simple header and cap installed. Capacitor isn’t really needed but couldn’t hurt anything.

Lazy photo :D

Hole in front needed to be cut out

Was a little rough

Will make a custom uart – usb adapter later.

Noticed that the main chip gets quite hot. So I looked at the schematic and found the 12v power supply.

Capacitor removed is where the 12v can be tapped for a fan. Removed the Capacitor as solder on it wasn’t as nice as it could have been.

Added power switch to mains and attached fan to 12v. Turns on and off with soft power so fan only runs when system is on :)
