These pre-built, analog thumbsticks were available for $99.99 from late 2019 – early 2020 from Maker-Matrix. See a video review of the controller.
The Maker-Matrix analog thumbstick controllers were a joint 2019 project by Herb Schaltegger, Jarrod Smith, and the guy who did the original design, Scott M. Baker. They are the first analog joysticks available for the Atari 5200 since the console’s original sticks. And for a console with legendarily bad stock controllers, this is welcome news. Printed shells are available from the Maker Matrix store and on Ebay. The PCBs are also available on Ebay.
Now that they’re no longer available as pre-built, finished products, you can build your own starting with a $15 blank PCB, a 3d-printed shell, and a bag o’ electrical components.
