The company has released four modules, with plans for a fifth in the works, all designed to be configured to function just like a variety of individual analog cards, and all for a cost of less than half a single card. The PWD00A-400 can drive Parker open-loop proportional valves with ramps and setpoints as standard parameters. The PCD00A-400 can drive standard open-loop throttle and pressure control valves, also with ramps and setpoints as standard parameters. The PWDXXA-400 drives high-performance valves with spool feedback, and the PZD00A-400 replaces accessory cards. The PID00A-400, currently in beta testing, processes external closed-loop control of cylinder position, pressure and velocity, providing +/- 50 mA direct servo drive. All models are configurable with free interface software, snap on a standard DIN rail, and use plug-in electrical connectors.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
