Haptic Touchscreen Example Application

  • 13 October 2014
    • Haptic Touchscreen Example Application
We are seeing a wide range of manufacturers implementing touchscreens in their products. Whilst they've been commonplace in the mobile arena for some time, now products like various whitegoods, information kiosks, printers and even industrial CNC machines are replacing dials and buttons. Adding haptic feedback to touchscreens is very simple, we outlined some mounting options in Application Bulletin 014 : Mechanical Layout of Vibration Motors for Typical User Interfaces and Controls. To compliment the mounting guide, we’ve added a…

AB-025 Released : Using SPICE to Model DC Motors

  • 2 October 2014
    • Basic electrical and mechanical equivalant of a DC motor
Our latest Application Bulletin walks through modelling DC motors in SPICE. For those unfamiliar with SPICE, it’s a very popular open source program designed to let you build and simulate electrical circuits. It’s widely used by students and professionals, but as with all software it requires some basic knowledge to get the most from it. So in this AB we’re explaining how to model DC motors. We don’t just cover basic DC motors, but also vibration motors and gearmotors.…

AB-024 Released : Introductory Gear Equations

  • 18 September 2014
    • A gear of 60 teeth attached to a 16 teeth gear reduces the speed by 3.75
Our latest application bulletin is slightly less challenging than some recent releases, but tackles a topic which generates a lot of support requests - how to calculate speed and torque in gear chains. We carry a wide range of gearmotors, but there are obviously instances where creating your own custom gearing is required. Perhaps you already have a DC motor, or can’t find a gearmotor that exactly meets your specification. This application bulletin provides you with the necessary equations…

Rugged Piezoelectric Passcode Haptic Example

  • 26 August 2014
    • A Piezoelectric Sensor
We've written a new example application for the Haptic Feedback Evaluation Kit. Piezoelectric sensors can be used for a variety of applications, but we chose to look at using them for touch buttons. They're great because they don't get damaged as easily as normal contact switches (such as from moisture or dust), but they lack the tactile response of a physical button. So we used our Haptic Feedback Evaluation Kit to develop a simple passcode system. Using 3 piezo…

Harvard's Kilobots Driven Using Vibration Motors

  • 18 August 2014
    • Harvard SEAS' "Kilobot"
The School of Engineering and Applied Sciences at Harvard University have created an amazing group of autonomous robots called ‘Kilobots’. The key detail is the robots are able to work together and arrange themselves into complex structures. To position themselves, the robots use two coin vibration motors with an impressive degree of accuracy! Whilst the Kilobots have been in development for some time, SEAS as released a new video showing 1024 of them making different shapes: The locomotion looks…
