We love capacitive touch screens. They’re much more robust than resistive touch screens and if the UI is programmed well they produce a great user experience. But getting your electronics project to interact with one is a bit tough. [RobB] has been experimenting in that area, and managed to build a simple touchscreen actuator for microcontroller [...]

[Fred] likes to squeeze every cycle possible out of his graphics card. But sometimes pushing the clock speed too high causes corruption. He figured out a way to turn a knob to adjust the clock speed while your applications are still running. The actuator seen above is a Griffin Powermate 3.0. It’s a USB peripheral which [...]

Yep, if you’ve got a button that needs pushing, this is one way to do it. [Travis] combined an old alarm clock with a car door-lock actuator and minimal logic circuitry to make this happen. When the alarm time is reached, the adjustable actuator comes down to press whichever button has been placed under it. [...]

[AntonB] has modified a servo into a powerful linear actuator (think: changing rotational motion into linear motion). The process is simple enough, modify a servo for continuous rotation and then add the custom built actuating shaft. You do of course lose the precision of the servo, but a small price to pay to be able [...]
