PROJECTS

The final project was to create a console game usable on a PAL TV system.
To test the video out put I sent a bar line signal of colours white, gray and black from a breadboard assembled circuit.Then A couple more signal test.
The housing was cut out from acrylic using the laser cutter.
I then proceeded to design the circuit in eagle and cut it out in the vinyl cutter.
Finally I populate the board. The circuit was pretty simple it consists of an Atmega328, a switch and 5 buttons as the main components.
Outputting data to the screen at a resolution of 0.4 microseconds proved to be difficult as SPI was not outputing data as expected.
I did create a second version of the board only to find a couple of errors such as the pot was connected in series with the LED which I almost 'fried' with too much current, solved that by jumping the LED and connection a 1K resistor in series with the pots. I then ran into problems trying to display from this particular board though i suspect it's issues with timing.
