Infrared LEDs[Bearbeiten]
The perfect LEDs aren't found till now. The SMD LEDs have a too big opening angle, 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]
- Start soldering with the uC (ATTINY85V)
- C3 and C4 both 22pF,0603
- Go on with R3(1 kΩ, 0805) and C1(100nF,0603)
- With soldering the plug connector and the Batteryclip you ended this part - Mind the polarity of the battery clip!
- XTAL1 (8 MHz, on the other side)
Part II - Programming[Bearbeiten]
All parts are on the PCB - now start with programming the board.
- 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).
- test for short circuit
- plug in the programmer Port P1
- 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 ...
- 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 :)
