This page is a tool made for people to use for the 5x7 LED Dot Matrix Pong created by Hakon A Hjortland, Havard Moen, and Alf Storm.
Files associated with this project (schematic, source, part list)
I have currently took on the challenge of familiarizing myself with a 5x7 LED Dot Matrix Pong project that I found: http://heim.ifi.uio.no/haakoh/avr/. This was created by Håvard Moen, Håkon A. Hjortland, and Alf Storm. When researching the project, I discovered that there was no schematic or parts list on the original site, so I went out and created my own! I e-mailed Hakon, and he replied with a general parts list. The replied message is shown below:

* Decoupling capacitors: 100nF ceramic for example
* 5x7 LED matrix
* Series resistors for the 5x7 LED: 1kOhm for example
* Score indicator and power indicator LEDs with series resistors (1kOhm for example)
* 5V voltage regulator
* Power supply. For example 9V. Or direct 5V instead of using voltage regulator.
* Parts for home made upload cable:
Essentially DSUB25 connector (or is it 23? I don't remember!) and
This is a general outline of parts, but I needed something more specific, and I want to share the information I created. The specific parts list is shown below:

Enclosure: Mouser has some decent enclosures with battery space built in. They are like a GameBoy enclosure only "blank".
*Prices are in USD
Also, I had to draw up a schematic for this project, as there was not one supplied on the original site. My schematic can be found here. I will keep everyone posted on my progress, but in the mean time you should really check out the other things on Haakoh's website; did you know that he also made a laser animation projector?!
