UC Berkeley engineers developed a robot that can traverse complex terrain and quickly avoid obstacles.
Most insects and spiders climb walls and walk on ceilings through sticky footpads, allowing them to stick on surfaces. UC Berkeley engineers used the same electrostatic adhesive concept to develop an insect-sized robot with similar swerving and pivoting capabilities as a cheetah. As a result, the robot can travel through a maze while avoiding sudden obstacles.
I’ve wanted to build a top shelf 3D printer kit for a while, and now I present part 4 of the Rat Rig V-core 3 series. In this video we try out input shaping using an accelerometer, which was my primary motivation for building this machine. It didn’t disappoint and in my opinion represents a major step forward for 3D printing.
In this fourth episode, we also cover questions and comments from part 3, basic calibration, pressure advance and high speed test prints.
Using a 3D-printed housing, a Raspberry Pi Camera Module, Raspberry Pi Zero, and LiPo battery, befinitiv has given an old camera a rebirth.
Pseudonymous maker “befinitiv” has shown off a Raspberry Pi-powered upgrade for film cameras, turning them into digital cameras capable of stills, video, and even live-streaming — albeit with considerably different zoom from their stock designs.
“This was state of the art 50 years ago,” befinitiv explains of a Cosina Hi-Lite film camera. “Back then, of course, you shot your films or photos on these films, and this was rather expensive back in the day — but today it’s even more expensive and a bit cumbersome.
If you want to design your own hot-swappable mechanical keyboard, this OpenSCAD script can help.
Mechanical keyboards are all the rage these days, and for good reason. They are more pleasant to type on and may even help to prevent repetitive stress injury (RSI), which is a problem that affects many office workers. Cheap keyboards have membrane switches, which are mushy and force you to push a key hard to ensure a key press is registered. Mechanical keyboards, on the other hand, have mechanical key switches that have a clean and consistent “break” point. Some keyboards even let you swap out the key switches to customize the feel. If you want to design your own hot-swappable mechanical keyboard, this OpenSCAD script can help.
Never again do you have to check whether your water is boiling. Put on your headphones and let your phone notify you!
Have you ever had to wait for your water to boil to make some pasta, but you hate waiting for it? Or, has it ever happened to you that you put the water pot on the stove, put on your headphones and forget you ever left it there? If these bring some resemblance to you then we have the perfect product for you!The Arduino BLE paired with our mobile app allows you to do other important things while the water is heating up. When the water boils, the app simply tells you that the water is boiling, even if you’re in another room.So put the water on the stove, turn on our device, put on your headphones and relax. We’ll take of the rest. 🙂
In this video, I’m exploring the idea of having your own I2C slave devices and sensors where a helper Arduino is used just for the sensor and the main controller does all of the control logic.
In my case, the slave I2C device is a dedicated controller for a motor speed controller (AC dimmer) that monitors the AC zero-crossing point and it listens on a specific I2C address for the speed at which the motor should run.
By using two separated Arduino Nanos, I can utilize the interrupt pins on both controllers where the one on the slave device will monitor the zero-crossing signal and the other one can be used for interfacing with the UI through a rotary encoder.
I saw an awesome video by Hand Tool Rescue of a 100+ year old fractal vise being restored and just had to have one. CAD and 3D printing makes this possible and if you own a 3D printer you can have one too. You won’t believe how awesome this vise design is, it can morph to clamp almost any shape!
A simple and fully automatic, 12V uninterruptible power supply system for small/medium power appliances.
Electronoobs shows how to convert a conventional clothes straightening iron into a PCB reflow hot plate.
When you see the word “iron” here on Hackster, you probably think of a soldering iron, used to construct a wide variety of electronic projects. To the rest of the world, however, an iron instead means something that is used to straighten clothing – an item that is produced in mass quantities, and which is both widely available and inexpensive.
