Cheap surface mount prototyping stickers
Protoflex makes a bunch of stickers with surface mount part footprints. The sticker goes on a protoboard, and then a surface mount part is soldered to the sticker. It’s a cool system, but very pricy. We covered them previously. Kelvin found a cheaper alternative: I have previously mentioned about protoflex. Unfortunately, it was too expensive. […]
App note: Tactile feedback with piezoelectric shakers
An introduction to piezoelectric-based actuation: Implementing tactile (haptic) feedback in consumer-electronic devices enhances the user’s experience. It provides a sense of touch in a user-interface design and is the newest major interface on smartphones and other portable consumer-electronic devices.
