EAB's Build your own Amiga Hardware Project
EAB's : Build / Design your own Amiga Hardware Project History: Have you always wanted to make your own Amiga upgrades but lacked the sources to begin. well after some work with some simple microcontrollers I had a though about changing the form factor of my a600 cpu so it could use A500 upgrades (as A600 upgrades are few and very far between). Aims: It is my hope that this project would exist to create OPEN SOURCE adapters and upgrades for the Amiga, It is the aim of this project to also act as a repository of information that is either difficult to find, or just better explained. Above all its main aim is to design and develop as a comunity simple hardware based on existing OPEN SOURCE projects where every member can act as council suggesting improvements and design ideas. Outcomes: It is the hope of this project that eventually professinally printed circuit boards can be produced in various areas of either the country or world really. From single testing boards right upto the possibility of mass production. Requirements: Just you and your ideas, although electronics knowlege is good, it wont make any difference in design ideas or concepts. so just bring your ideas along. Tools Here are some links to freeware tools to help you in your designs.
for a full list of tools and links Components & Sourcing Here is a list of places to get components Last edited by Zetr0; 13 August 2007 at 13:35. Reason: added some tools and component sources |

AMiX 3 in 1 Internal Stereo Mixer
Heres a simple one to begin with.
This would suit a Desktop / Wedge Amiga with an internal SFF CD/DVD RW/ROM The idea is simple as it combines the audio signals from the amiga with two other inputs without damaging them. Click to Enlarge single layer eagle pcb download you will need to modify your Amiga's Audio out or create your own to output the combined audio signals |

A600 CPC (Amiga A600 Chip Package Changer)
The idea of this is simple I wanted to have a simple upgrade path for the A600 as there are a lot of A500 cpu chip-upgrade adaptors i figure it would be nice to tap into that. so here we go..
this is a two layer PCB design with NO drilling, so its a case of flip / print / etch and then solder. This would fit in an A600 but would most likely suit a towered or re-housed a600 mobo. Click to englarge dual layer eagle board pcb NOTES:

Zetro why are you so cool?
I wish I could just whip up schematics and ideas for Amiga upgrades just like that haha. |

@Boing
its all about being in the right environment... and here at the EAB, IS the RIGHT environment. but the main reason i am cool is the fact I have a 2 foot fan i front of me on force factor 5 ... i dont do well in the heat LOL. |

How about schemas for making pcmcia connected CD-drive (ide or scsi?)
or even USB? ( card reader / USB HD / USB CD/DVD ) I could loan a biig fan to make it happen?? =) |

@Huezo
It may be possible to get USB 1.1 on PCMCIA. infact i may be able to implement the stack on a micro-controller with a little bit of ram..i have some sources I will looking into after i look into a fast ram module for an A600 @Turrican3 Ideas are good, simple things like making your own PSX to amiga controller etc PS2 mouse... that sorta thing... or crazy but cool ideas like internal bluetooth etc. etc.... |

I have not done anything on Amiga and USB either =)
But I guess that USB is not rocket science codewise. (well rockets fall sometimes too) The PCMCIA as being external is handy to use for attaching devices. There could be a PCMCIA dock and switch. On the other hand.. anything can be used VIA USB. I guess there are physical switches for it. CD-ROM/card reader, or something like that. BTW what is the speed roughly, like tested with PCMCIA CF ? It is interesting thought of making actual protos out of ideas. I did Tetris with C & 8051 microcontroller at school few years ago, but am not really deep in HW designs. |

Was thinking of putting Bad/faulty CD32 controller inside XBox controller. - is this just combining 2 controllers parts in this case? |

@Huezo,
The XBox controller is basically a USB hub and this uses a different method than direct pin asignments like a cd32 pad. heres some more detail on the xbox controller http://euc.jp/periphs/xbox-controller.en.html arguably you could convert the cd32 controller into using this http://eab.abime.net/showthread.php?t=31515 (i may redesign this design *again& and make it 2 layer non drilled) but it would require a little experimentation with some of the code to get all the features of the cd32 joypad. |

@Zetr0
I really can't just rewire the xbox controllers digital buttons to cd32 pad butttons' wires ? ? Well.. must consider this. BTW i think I need dremel (for some purposes) Is the lithium one a go or no, or just the wired one? |

@Huezo,
indeed, you could use the controller board if you wire up the buttons directly with the cd32 pad, you are most certainly gonna need a rotary tool like a dremmel . Quote:

Actually that was about Dremel wireless one stylus something, is that ok? =) This one would be useful with XBox when playing with emulators. http://www.raphnet.net/electronique/...b/index_en.php NOT THAT I EVER play much anything!!! =) Just collecting stuff and never time to use it LOL! OH, is there cheapo place for components? =) |

@Huezo
yes that is most certainly where i got the original design from for the usb to db9 joypad controller... infact I even bought te chips from there as well... the guy sells kits i believe so its very easy to make yourself. |

Zetro is our very own Dave Haynie
How much would you build an A2000 with AGA chipset for good sir? |

@ALL
LOL guys, I am no where near the knowledge and skill of david haynie.. infact all that I put up here has been realised and designed (probly better too) else where LOL... I have a basic micro-electronics knowledge.. and a smidge about programmable IC's but when we start talking verilog or GAL's imma reaching for page one in the reference book LOL, I do have good software engineering skills when i find something that interests me LOL... @paul_s hmmm a2000 with AGA, you know they brought out that Graffiti adapter (from individual computers) is basically gives you a a programmable chucky 8bit screen (from a 16bit pallet), thats compatile i think with any amiga RGB out... personally i felt gens should of made an el-cheapo internal version.... but you could argue that it would outperform an basic A1200 with AGA. (especially with DOOM / Hexen) after all on a basic level its a 6:1 reduction in calculation.. @dizzy hmmm dreamcast controller eh?.... interesting..... |
