Proposed Projects: Please vote by donation

Okay here are the three projects that I am wanting to pursue this year and hopefully finish. The first two are a continuing variation on work I’ve already done, but with some extra refinement. The third is something of a radical departure from what I’ve done in the past, but at least it is off the drawing board and into the actual testing phase already.

To repeat parts of my previous post. Whichever project gets the most donations in the next 60 days is the one I will focus on to completion. The highest donor will get the most discount on the final product and the most say in design. It won’t be completely free, but you will see a 50% discount. The second highest donator will see a 25% discount. Final design decisions still rest with me, but only because you can want all you can, but that doesn’t make it realistic, doable, or sell able to other people, which is kind of the point.

I’ll keep track of the amounts for each project and towards the middle of April I’ll declare the winning project. To have a winning project I need at least $100.00 donated for that project. If no project reaches that mark, then I’ll distribute the monies donated to the various projects and continue working on them in the background.

Atari XF551 compatible 3.5″ 130XE internal and Hammond Cased External Floppy Drive Boards

Currently I have reached beta testing phase on both versions.  A few bugs to work out given the new 26pin interface to the Slimline drives and some display board refinement needs to still be done.

I hope to offer the 130XE internal main board and display auxiliary board as a semi-finished set of boards (you would need to supply the slimline drive and data cable, and the WD1772 and Intel 8040/8050 chips.  Since this is a combination SMT and TH board, I would think this would be beyond the ability of many purchasers to assemble.   Extensive 130XE case modding will be needed.

The externally cased XF551 3.5″ version right now is expected to be housed in a suitable Hammond case and sport a 2 digit track # display, reset, front drive ID and bios selector switchs. I will be providing the main and front panel board with front panel. You will need to purchase the Hammond case and WD1772 and Intel 8040/8050 chips and the drive and data cable for the type of drive you want to use.

I got this idea from work that was done by Zaxon last year.  He provided a short run of both standard 5.25″ and 3.5″ externally cased drives and a version that would fit in a 130XE internally using a Dell Slimline 3.5″ drive.    Kudos to him.   My design is a little more refined, with a few extra features.  It borrows from work I’ve already done on earlier XF551 type boards.  It also would be produced domestically, thereby reducing shipping time and cost.

This is the beta version of the external XF551 3.5″ standard/slimline floppy drive board with proto track display,reset, bios select and front drive id selector.

Atari SIO2IO Externally Housed Combo board

This project is still in the beta design phase and it’s exact specs will change. In general it will include the MIDI2SIO in/out connections by Mytek, DB25 parallel printer adapter by Supra Microprint, a basic DB9 Rverter serial port and the finished FujiNet wireless hardware project and be self powered. It should be compatible with nearly all Atari 8bit machines and be connected via a single SIO dongle. At this point it should be able to be sold either fully assembled or as a bare board with BOM.

This is a design mockup of an externally housed SIO2IO board.

Atari Wireless CX-40 Modification

This project is a little past the paper design phase and into the alpha proto board stage.  I have verified basic wifi connection between an unmodified Atari CX-40 joystick connected to Arduino Pro Mini and a nRF24L01+ for a transmitter and a Arduino Pro Mini and nRF24L01+ receiver connected to the Atari 8bit computer joystick ports.  There is some lag and I still need to work on optimization in the software, but the basics are there.

I am also working on a drop in board for the CX-40 joystick that has a minimum amount of case mod.  I plan to have USB recharging ability for the battery and a led that indicates battery status, with an ON/OFF button to save on battery usage.   On the receiver board that plugs into the Atari 8bit computer port, I plan to offer a version for the Atari 130XE, 800XL and hopefully the 1200XL.  That board will sport a small OLED display indicating status of connection.

This board is almost exclusively SMT and I don’t feel comfortable selling any thing but a fully assembled set of two joystick insert boards and a Atari 8bit receiver board. I plan to eventually have a receiver board that will fit all Atari 8bit machines.

This is still a little rough in design, but it is getting closer to a final design.

Understand no monies will be returned and unless there is a winner no discounts given when the project reaches the release date. Hopefully there will be no tie breaker needed.

Vote donation has ended. The Atari SIO2IO externally housed board is the winner
