Picture of Portable Led Game System

This is a really easy to do video game system with a LED screen.
I made it trying to keep it as tiny and cheap as possible.
It uses only one IC, a PIC16F628A and 9 bipolar transistors, has 4 buttons for control and a swich for turning it off.
It also has a tiny speaker for making some sounds.
The power is given by four ni-mh batteries, and the consume is so reduced and you will keep them charged for a long time.

Games: So far I have only programed three games but I gonna do more in the near future (see steps 9,10,11 and 12  for more info about the games).

I hope you like this instructable and make your own portable game system.

Ps: I am from Argentina so let me know for any grammar mistake.



Step 1: Stuff you need

Picture of Stuff you need
led schematics.png

It just use some electronic components, most of are them recycled.

Transistors: Use 9 transistors BC548 or similar.
Even 2N3904 can be used but their terminals are opposite, very careful when soldering if you choose these ones.

LEDs: they are at the forefront of this project. Only the four lower LEDs are RGB, the rest are common red LEDs.
If the light is different from the LEDs you can diffuse then using a sandpaper.

Switches: try to get good quality switches. I used switches from a monitor for the shoulder buttons and I bought the front ones.

9 - 1k ohm
4 - 220 ohm
4 - 10k ohm
1 - 560 ohm

1 - 100 uf
1 - 100 nf

Microcontroler: PIC 16F628A

Misc: An on/off switch, a piece of plastic, 8 screws, 8 spacers, 1 piezo transducer (the little speaker that looks like a coin).

When I open winpic800 it says can't install WP800I0.sys and it won't let me program it :(

Hola Bruno, tengo una duda, las tablas de color café son de cobre? Y esa lamina de cobre se pone en una tabla de plástico?
olvídalo, ya lo resolvi

Puedo usar en vez de un PIC 16f628a un microcontrolador que se llama RX-2-G 90507285?

Hi Bruno,

First off, this is an amazing idea, and your English is very good.
Please could you tell me the dimensions (how big it is/the size) of the game system? I want to know what size board to get.
Many thanks,

Hey I saw this other guy or the same guy idk but he made the same thing but with 2 games on it but you had to reprogram it to change it.

The translation to franchu's comment is:
forgive as it does to programme and to unload the file hex because it is opened in the explorer. greetings

disculpe como se hace para programar y descargar el archivo hex porque se abre en el explorador. saludos
How much does this cost? Oh, yea very cool!

i see you don't use a multiplexer for your led matrix . did you program the pic to act as one?
hola, por favor me lo pasás por E-mail? (facup2000@yahoo.com.ar) grax!

Nice job, I have only two questions:
first how long did it take you to become this smart?
second if i used a PIC16f628 would there be any difference at all?

Arent the codes too big for the Pic because the pic can only hold 3.5 kb. So if i was touse a different pic say PIC16F88-I/P would that work?
