Recently, scientists at Pylos Labs have discovered how to construct automatic devices powered by eumonetic energy. These devices can be built to perform any sort of eumonetic technique. They are completely self-contained, meaning that anyone -- even those who are not eumonetically inclined -- can use them.
Eumonetic devices draw their energy from eumonite. Thus, charged eumonite works sort of like a battery. Pylos sells eumonite to go along with their devices, and will recharge spent eumonite for a fee.
How, exactly, eumonetic devices are created is a closely guarded secret. The result, though, is that a device can be built which will perform any specific eumonetic technique every time you pull its trigger.
Usually, a very simple, general technique is used, while some sort of mechanical component is used to direct the device. For example, if you wanted to create a flying device, you would not use eumonetics to perform things like "move vehicle forward" or "turn vehicle right". These statements are too specific, and would have to be applied differently every time the vehicle is used. Instead, you would use general eumonetic techniques like "levitate" and "create wind", then use mechanical means (like a sail) to control your movement.
Other examples of eumonetic devices:
A gun which works by using eumonetics to push bullets out of a tube.
A healing wand which heals people it touches.
An item which draws pure water from an impure source.
Interestingly, although eumonetic devices can clearly do many things that electronics (in our world) can't, there are also many things that electronics can do which eumonetics can't, including:
Computers. There is simply no way to produce an interactive eumonetic device.
Communications devices. Eumonetics cannot be used to encode or transmit information.
