I ordered a Tiny-G motor controller a few days ago. It’s version 0.9, but considering I’ve been trying to get my hands on a pre-release for about a year I don’t mind.
The CEE (control · experiment · explore) is an analog multitool. By sourcing and measuring voltage and current, the CEE opens up a world that has previously been restricted by monolithic, bulky, and hard-to-use tools. Learners can explore a wide range of concepts including everything from AC/DC electricity and resistance to work / energy, torque / speed, heat flow, and electrochemistry. As tinkerers, we’ve used our proof-of-concept boards as a multimeter to sort components in our junk bins, a programmable interface device to test new sensors, a power supply to fuel our breadboards, a web-based datalogger, and every possible combination therein.
TinyG is a many-axis motion control system. TinyG components execute G code directly without the need for a general-purpose microcomputer. TinyG is meant to be a complete embedded solution for small motor control. The design goals are to build a board that can handle most motors up thru NEMA23 and be networked for multi-axis motion control well beyond just 3 or 4 axes. — Synthetos
