Way cool project Art. Thanks for sharing.

P.S. Really liked the wavy line thing in your video. Very creative.

Very nice!!!!

Nice job Art! The wavy string was awesome.

Thanks for the comments

Version 2 eliminates the need for the external EEPROM,
improves Tetris scoring system (where it's worth more to get multiple rows simultaneously),
More fixes described in the source code header.
Cheers, Art.

Heheh, remember the the old Mattel handheld football game, I bet you could write a version of that game for your unit.

Hmm, I'm 35, so I might have been around for something like that, but don't remember it.
I have made room for another game on the same chip though

From what I've seen so far - I'll bet you can come up with a boat-load of very cool games for this one.

I'll look at making a board for it with surface mount components, and ICSP header. I think this would be a really cool board for people just starting out with PBP.

I'm thinking of an action game next, like a lo-res sideways shooter or something.
A playable Pong would be easy, but pretty boring with fixed angles.
I am looking at fitting as much as possible on the 16F877/A.

If you make better hardware I really hope you'll consider selling me one
(or at least sharing the PCB layouts, etc).

I've got to look at making PCBs soon... Just got my first PCB kit with a pen,
but I think I should have moved straight to the photographic kind.
It's too much to stuff around with transfers for IC footprints, etc.
I think I'll just try some sort of radio with these etchant resist pen type.

Is there a reason why the version 1 package has the files pic.bas and SCROLL.hex while the version 2 package has pic.HEX and scroll.bas - have the hex files by any chance crossed over into the wrong folders?

I am going to make this one, for sure. It will likely be a hand-etched iron-on laser toner board, but maybe I'll use perf board. Where are you getting your proto PCB from?

Great project by the way, well done.

Can't speak to the firmware; Art is responsible for that.

As for the PCB, I'm still working on it (I've been slammed with work - right now I just got finished laying out a USB drive MP3 player. I'm also doing a Class D amp, a guitar effects processor, an audio mixer and a microcontroller "brain" for the lot)...

I just finished an 8 channel RF remote control system with capacitive touch input controls for "work". I'm trying out a PCB manufacturer that posted an ad on this forum. Their prices are very good and the guy I'm dealing with has been very responsive. I should have the boards back in a week or so; I'll let everyone know how they turn out.

[Ioannis]

Please do!

Thanks,
Ioannis

The hex file is just renamed from "scroll" which is the project name in MPLAB.
I'll upload a new schematic. The first one has an error where the transistors are.
Unfortunately I can't edit earlier posts, so I deleted the image from the host. The parts list is correct.

I got my protoboard from Dick Smith Electronics which is an Australian electronics store.
