So, I was looking at this sire: Dual Atari joystick adapter (http://kair.us/projects/dual_atari/index.html)
Lovely project, excellent form factor and good functionality. Unfortunately he's not offering the item, just schematics... I looked throught he links he's giving to other similar projects but they're not that good - each one lacks something. Maybe this (http://www.sinchai.de/index.php?main_page=product_info&cPath=1&products_id=137&zenid=d58df6364714de6f07c0230d6c5470ad)?
Any ideas? Has anyone tried something of the sort? Do you own anything?
I used the ZX USB Joy project to connect my joysticks to the PC. Another project, which does nearly the same, is the "USB Joystickadapter (http://www.hexagons.de/index.php/USB_Joystickadapter)". You can also order kits from them and it is similar to the ZX USB Joy project.
Ah, the link you gave is the same project as the second one I mentioned (but I gave the shop, not its homepage). It's cheap enough - do you think it's any good?
Ah, what a pity, the cased version is out of stock... :(
The the Atari one would be pretty easy to run up a batch of them (without the case).

Sorry, didn't catch you? :)

Bryce.
Lol... I assume you mean someone could produce them easily, which is probably true, but who? Was asking about a ready product :)
Well if there was enough people interested I'd run up a batch.
Bryce.
Oh, that'd be nice indeed... What would the cost be you think, for maybe 10-20 units?
I've built a few USB converters for old joysticks and for interfacing arcade cabinet controls to PC's.
There based on Atmel AVRs using V-USB (http://www.obdev.at/products/vusb/index.html) and easy to build on stripboard - space can be an issue on some smaller joysticks though for the stripboard solution.

With professionally done PCBs, probably around €35 to €40 each.
Bryce.
Ooh pricey! Is there an advantage over the €15 one that Octoate suggested?

Well if I ran off a batch of 100 of them I'd probably get them down to about €25 or less. 10 units is a prototype batch (it's the PCB price that effects the price the most).
No, same function different components.
Bryce.
But I doubt there are 100 people here wanting these! I'd certainly prefer yours over some unknown quantity, even if more expensive, but it doesn't look like it's gonna happen :(
Who makes your pcb's Bryce ?
Depends on what type of PCB it is, whether it needs gold-plating, SMD or thru-pin and how many layers. A lot of my stuff is done by PCB-Pool. I don't use Chinese companies due to bad results in the past.
Bryce.
Oh right, never had problems with Fusion/Itead PCB's myself apart from slightly inconsistent colour solder resist on different batches.
Never had gold plating done though or pushed them to their manufacturing limits.
I just received a small batch (3x double layer board of 53.47x44.60 mm) from a place in the USA called OSH Park. OSH Park ~ Welcome (http://oshpark.com/)
They use ENIG (gold plating) surface finish, and I am really impressed with the price, quality, and the speed in which i received the boards.
Ordered on the 5th January and received on the 22nd January (USA to Australia). $18.45 USD delivered.

Wow, that was a good price.
ENIG gold-plating is only for solder pads. I meant gold plating for non-soldered areas such as an edge connector. ENIG wouldn't work for that.
Bryce.
Hi Bryce, the whole board is gold plated including the edge connectors.
Have a look at the exact type of board I had made...this guy made the design available.
CoCoEPROMpak: A PCB for EPROMs in the TRS-80 Color Computer Cartridge Port » (http://www.nf6x.net/2013/10/cocoeprompak/)
You can see my "Thanks" message at the very bottom of the page.
He has some good pictures that show the quality of the boards.
Cheers,
Shane
Here's one of mine...

Ok. That's only ENIG plated. The edge connector will oxidise and dull pretty quickly. You'll have to clean it regularly, but you'll be back down to the copper pretty soon. ENIG is only meant to protect the bare copper until it is soldered, it has a life-span of about 6 months to a year. To make real edge connectors like the original cartridges you need full plating which is a completely different (and relatively expensive) process.
The quality looks very good otherwise. Especially as the tracks look like they are 5mil?
(But the U1 VPP track is a bit under dimensioned)
Bryce.
It'd be very easy to build a joystick adapter out of something like the Atmega32u2. These are the chips I use for USB-JTAG bridge and SD card interface in my FPGA project, they're a couple of quid and have USB support built in (the u part of their name).
LUFA (a free USB stack) even has an example joystick device, it'd be pretty trivial to extend this to 2 joysticks and there are enough IO pins to handle 2 Atari sticks.
You could buy something like the Teensy if you want the chip on a pre-built board: Teensy USB Development Board (http://www.pjrc.com/teensy/)
That's exactly what the device above is (take a look at Gryzors link). A PIC with built in USB Host/Client. The design isn't difficult, it's the production of decent quality devices being discussed.
Bryce.
The VPP track is the same width throughout.

But anyway, I was mainly indicating a PCB fab that is reasonably priced, has a quick turn around and small batch friendly (from my personal experience) :)

Shane
So it is. In the first picture it looks like it's a really thin track here:

That's just my crap photography skills...wrong angle & lighting.
