Being able to derive the absolute position of an object is vital in countless applications, primarily for anything that uses a motor. Instructables user holybaf had the idea to build their own rotary encoder, which has 60 degrees of resolution and utilizes a CD to act as a precise clock. To accomplish this, they first laid down a […]
Self-propelling robots come in a whole host of shapes, sizes, and capabilities, with some being able to fly while others can walk on just a couple or many legs. But YouTuber James Bruton wanted to innovate on this concept even further by designing and building a robot that mimics an earthworm through extending and contracting segments at certain times […]
Capacitive touchscreens today use a digitizer to pinpoint the coordinates of a finger tap. That makes sense for smartphones and tablets, but isn’t ideal for large scale applications. If you want to recognize touches on the scale of an entire wall, a Kinect sensor could be more appropriate. But such a setup traditionally has a […]
The classic MP3 player was a truly innovative device for its time, however with the advent of modern smartphones and other do-it-all gadgets, they have largely fallen by the wayside. In order to add a new twist, Norbert Zare decided to implement an MP3 player that not only responds to user inputs by moving the volume knob and tilting […]
Arduino Cloud has a treasure trove of new features waiting for you right now. Not least among them is mobile optimized dashboards, and the option to log into your Cloud account using your Facebook credentials. Take a look!
Arduino Cloud is now fully interfaced with the popular, worldwide LoRaWAN platform, The Things Stack. You’ve now got a great way to connect devices in remote areas or from much, much further away.
3D printers are very popular in the maker community and CNC machines complement them well. While 3D printers fabricate parts by adding material over time, CNC mills and routers fabricate parts by subtracting material. That is preferable when working with large parts or when you require a lot of precision. If you want an affordable […]
Detecting shapes and gestures has traditionally been performed by camera systems due to their large arrays of pixels. However, Jean Peradel has come up with a method that uses cheap time-of-flight (ToF) sensors to sense both objects and movement over time. Better yet, his entire project is housed within a 3D-printed “Grumpy Hedgehog” that contains not only the sensors, […]
This year for Halloween, Quint BUILDs wanted to make something special for his daughter’s costume. Quint’s idea was to design and fabricate a pair of mechatronic dragon wings that can mount to a user’s back and move in three different modes by utilizing a set of pneumatic air cylinders. The prototype began as a single air cylinder connected […]
Driven by a desire to print massive pieces of art on his new studio’s blank wall, Shane Wighton of the YouTube channel Stuff Made Here set out to create a large painting robot, which he calls “Janksy” after the famous artist and the jankiness of the construction. In principle, the device works by using a large gantry that […]
