MAME adds to confusion by classifying 270 degree steering wheels as paddles. Since a pot requires physical contact, they tend to spin less freely than a true spinner. The paddles found on early arcade games (like pong) rotated a full 360 degrees but used a 360 potentiometer (or pot) rather than an optical encoder. Paddles are the precursor to the spinner. They often move things in a game in a circular fashion, as in Tempest or TRON. There is no end to how many times the knob can fully rotate in any direction. Note: Paddles, while similar to spinners in that they rotate and have knobs, are usually based on potentiometers (like a volume knob on an old TV or radio), rather than the optics in a spinner. You can find out more about optical encoders here. If the unit does not ship with an optical encoder, you can purchase one from an aftermarket seller. In the rare occurence that your spinner does not have optics included, they can be built with parts from your local electronic store, or you can build them based off of a mouse hack. Otherwise, you'll find that optics are generally included, but an encoder is not. If you are buying or building a working spinner for your cabinet, you will need the Spinner (the mechanical part,) the optics(the part that watches the spinning,) and the optical encoder (the part that sends info to the computer.) If a manufacturer advertises "USB Connectivity" that generally means that it is an all in one solution, and no additional parts are required. This is also how a trackball works, as well as a ball-type PC mouse. The combined signal from both of these optics tells the game which direction the disk is turning, and how fast. There are two sets of optics, spaced such that they see the notches spin by just a little bit out of sync. These notches pass though a set of infra-red optics, that detect the notches as they spin by. Mounted on the shaft, is an optical encoder wheel- a flat disk with notches cut around the outside edge. Underneath the control panel, the shaft comes down from the knob above. But what's going on behind the scenes what's that knob attached to? The player turns a knob to move the on-screen character. You might remember the spinner from games like Tempest and Arkanoid. 6.3 If I can have only a spinner or a trackball.6.2 Two Spinners on a control panel is it worth it?.6.1.7 Non-standard spinner and paddle game controllers.6.1.6 Steering wheel (potentiometer) games.6.1.4 360° steering wheel (optical) games.6.1.3 Roller (single axis trackball) games.6.1 Which games originally used a spinner/paddle?.
