===Infrared LEDs===
The perfect LEDs aren't found till now. The SMD LEDs have a too big opening angel, so the power is not enough for switching the TV off. On the other hand with 10° you have to target very perfectly... Another problem is that the board haas a bug for the SMD LEDs, if these are solded, they can create a short circuit, but this will be fixed for the next version.

Tutorial[Bearbeiten]

Part I[Bearbeiten]

  1. Start soldering with the uC (ATTINY85V)
  2. C3 and C4 both 22pF,0603
  3. Go on with R3(1 kΩ, 0805) and C1(100nF,0603)
  4. With soldering the plug connector and the Batteryclip you ended this part - Mind the polarity of the battery clip!
  5. XTAL1 (8 MHz, on the other side)

Part II - Programming[Bearbeiten]

All parts are on the PCB - now start with programming the board.

  1. download the firmware v1.2 from TVBGone/download.html and use a programmer of your choice. The software you need is descibed on this site: AVR Toolchain).
  2. test for short circuit
  3. plug in the programmer Port P1
  4. change in the Makefile to the right Programmer/Port:
...
#AVRDUDE_PROGRAMMER = usbtiny
AVRDUDE_PROGRAMMER = usbasp
#AVRDUDE_PROGRAMMER = stk500v2
#AVRDUDE_PORT = com3        # programmer connected to serial device
AVRDUDE_PORT = usb
...
  1. run make full


Part III[Bearbeiten]

Take the next part of your choice and solder it :) Please mind the polarity of LED5 (for the actual package, the green dot is the cathode)!

Testing[Bearbeiten]

Now you are ready for testing see TVBGone/test.html.

Testing Advanced[Bearbeiten]

Go to your electronic store of your choice and test :)
