The FlatFlap is an incredibly thin and innovative actuator, measuring just 0.3mm thick, designed to bring eye-catching motion to your projects.
Made from a flexible PCB with aluminum stiffeners, it folds together to create a low-force flapping motion. Its magnetic system converts electrical energy into mechanical movement, by using a 10mm N52 neodymium magnet on the back that interacts with a planar copper coil embedded in the PCB. When an electric current passes through the coil, it generates a magnetic field that attracts or repels the magnet, causing the flap to move. By alternating the current direction, you can control the motion, with continuous flapping speeds of up to 25Hz. It is easy to attach and comes with a color-changing sticker, allowing you to transforms your creations into dynamic, interactive art.
The FlatFlap comes pre-assembled with the magnet so no additional magnets are required. Just power the coil for it to be repelled or attracted to the magnet. Add an h-bridge like our tiny DriveCell, to control the current through the coil, and produce smooth flappy motion.
FlatFlap is perfect for anyone curious about electronics! It comes with well-explained Arduino examples, making it easier to get started. Since FlatFlap requires soldering, we recommend ensuring that soldering is done under proper adult supervision and guidance for children under 12. Otherwise one can also purchase it pre-soldered with a DriveCell. Please also note that the package includes small parts, like screws, so care should be taken when handling them.
Want to make it flap? To achieve this, you'll to switch some transistors like an H-Bridge to flip its polarity and adjust its position. That’s why we highly recommend our compact DriveCell module, its easily to use & only measures 0.8 cm wide!
