5x7 LED dot matrix PongSat, Jun 16, 2007 at 2:04AM
I have currently took on the challenge of familiarizing myself with a 5x7 LED Dot Matrix Pong project that I found. This was created by Havard Moen, Hakon 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:

I think that your work on the 5x7 pong project was excellent! If you could, would you please send me a parts list for the 5x7 pong project?
Thank you for your time, Davis
- 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: http://heim.ifi.uio.no/~haakoh/avr/uisp-parport-connect.txt Essentially DSUB25 connector (or is it 23? I don’t remember!) and wires.
– Best regards, Hakon
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:
|Description||Digi-Key Part #||Price/ea [DK]||Radio Shack Part #||Price/ea [RS]||Qty (individual components)|
|1k Ohm 1/4W Resistor||1.0KQBK-ND||.054||271-1321||.99||10|
|7805 5V Voltage Regulator||497-1170-1-ND||1.04||276-1770||1.59||1|
|100nF Ceramic Disc Capacitor||399-4454-1-ND||.13||272-135||1.29||2|
|1.5-3V 20mA LED||754-1264-ND||.09||276-1622||2.59||3|
|N.O.Momentary Push Buttons||EG2490-ND||.031||275-1547||3.29||4|
|5x7 LED Dot Matrix Display||160-1002-ND||2.29||N/A||N/A||1|
SPST Power Switch
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.
I will keep everyone posted on my progress, but in the mean time you should really check out the other things on Hakon’s website; did you know that he also made a laser animation projector?!
