The Opal Rotary Controller is now discontinued.
Due to a change of job, I just don't have time to comfortably build the Opal any longer.
I will keep this page here for historical reference.
I originally just made one for myself and ended up making 90 more, so a big thank you to everyone who purchased one!

Ever since Jeff Minter snuck the rotary code into Tempest 2000, people have been wanting rotary controllers for their Jags.
The speed and precision of movement that they offer is far superior to what can be attained with a digital pad. It has to be tried to be believed.
Tempest is no longer alone. There is an ever increasing number of homebrew games for the Jag which support rotary input.
The current list of supported games is:
Tempest 2000 (instructions at the bottom)
Virtual Experience's Pong
Take a look on AtariAge for more info on homebrew releases.
My goal with Opal was to make a high-end rotary controller that was different to any before it and was built to a very high standard. It had to look and feel like it came straight from the factory like this.
Built to last:
The encoder is mounted in the middle of the window, which phases gradually through several colours and gives the impression of the knob floating in a pool of light.
