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

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.

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

Capacitors:
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).

hola, por favor me lo pasás por E-mail? ([e-mail]) 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?

[Mr Sinster]

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?

[steve-lane]

This is the best design of a home made game I have seen yet. Very nice job.

[minijc]

could you play a driving game on this like a proper one

[bere-ivan]

can you help me with this proyect, cause y have to do one but really i want to know how to do it, cause i dont know how to start it! please i need a lot of help

[sajithjames]

can i get the c file for led racer??????

[ddbear]

wow! that is really awesome!!! i have got to make this!

[theawesomeninja]

I like how the only grammar mistake I saw on the first page was "Ps: I am from Argentina so let me know for any grammar mistake." :P but else the grammar's ok

[R.A.T.M]

could you do beam bot like free form or paper board

[robot1398]

how many pin switches are these 2 or 4

[mk2001]

4

[caco caco]

cool and cheap

[The nerdling]

tetris woooooooooh

[jwoo2023]

Looks like a gameboy micro!

[jwoo2023]

I don't have a laser printer :(

[Plo Koon]

That would be "about any grammar mistakes".

[kasta96]

can I use the .HEX file in the programm "IC-prog"?

[brunoip]

yes, you can

[robot1398]

can i just copy paste the code or i have to do something else

[MECHOL]

this fantastic but i can't this make

[mased007]

You are my idol. How old are you?

[brunoip]

Just put JDM on google

[hungohoy]

i have some problems in finding the parts where do i usually find this

[brunoip]

In a local store here in Argentina

[franmazz]

can i replace the 4 aa batts with 2 cr2025?

[brunoip]

Yes to the batteries no to the game. Regards, Bruno

[franmazz]

did you make another game for it?

[robot1398]

wheres the circuit digram i cant see one

[lunchweek]

Seriously, this is the best project ever. Thanks for sharing it.

[jrinehart]

Do you happen to have a complete schematic? I know you have the printable pattern for etching your own board, but I would like to build it without etching and use a regular through hole board. Thanks.

[kasta96]

hi!
first of all... compliments!

so, has the leds got tipical voltage, or i can go on an electronic store and take the first red and rgb leds that i find....

please replay to me!

P.S. i'm italina so.. if there are some mistakes don't care of theme!

[brunoip]

any kind of led would be fine

[kasta96]

ok thank you

[orgasmotron]

did you get it to work ?
i still can't move left right with the racer game
to other work fine (roulette and simon)

[FryingNemo]

how do i connect the LED pins is a row/column format? since RGB LED has 4pins including the positive(anode).. and can i use 2n222a transistors instead?

[Kiwicek]

HELLO ... I built it, but right and left buttons do not respond. The game works fine just can not move and that's it ... What to do?

[Kiwicek]

But Simon says the game works well. I do not know what is wrong =(

[orgasmotron]

same thing to me , i can't move left to right , i've double triple check
retried another pic , put new transistor, change button ,
can't get the game to move :(
