The NTH is designed so that a complete beginner can quickly craft incredibly varied timbres. For the synth veteran, the NTH offers relief from layered menus and obscured functions. The NTH puts a smile on the…
Ntablet is an open-source tablet for developers to learn and program. As a portable tool, it gives not only convenience to your projects, but also help to create more innovative designs as what you imagine. With it, you can start programming and developing anywhere, you can freely DIY and control TV, air conditioner, curtain, light, and…
There is no question that ESP32 is a worthy competitor to many WiFi/MCU SoCs out there, often beating it on both performance and price. But, depending on which state it’s in, the ESP32 can be a relatively power-hungry device. When your IoT project is powered by a plug in the wall, you tend not to care…
Every once in a while you’ll come across an idea where keeping time a prime concern. For example, imagine a relay that has to be activated at a certain time or a data logger that has to store values at precise intervals. The first thing that comes in your mind is to use…
Having two or more Arduino boards be able to communicate with each other wirelessly over a distance opens lots of possibilities like remotely monitoring sensor data, controlling robots, home automation and the list goes on. And when it comes down to having inexpensive yet reliable 2-way RF solutions, no one does a better…
Seems like everybody’s getting into the AI and robotics game — at least the companies and research institutions that can afford to build their platforms from the ground up are. France’s Pollen Robotics, on the other hand, aims to kickstart the robotics revolution with its open-source system, Reachy. The robot, being open-source, is capable…
Infinity cubes and icosahedrons are things that have always caught my eye. They however always seemed quite hard to make, because of the relative complex frame. This infinity cube, however, has a frame that is printed in one piece. Making the build a lot stronger and easier than most other projects. The…
A hand-held plasma cutter is an excellent tool to have if you are working with sheet metal, but it’s not particularly well suited to making long or repetitive cuts. Which is why [workshop from scratch] worked his usual scrapheap magic and built his own motorized track for making perfectly straight cuts. More info
We’ve all seen plenty of impressive free-form soldering in these pages, maybe some of us have even had a go ourselves. Using nothing but bare conductors, electronic components, and solder, complex and beautiful electronic sculptures can be created. But the latest free-form project from [Jiří Praus] takes the medium to a new level, as he’s taken…
Hey guys, welcome back. In my previous post, I explained what an H Bridge Circuit is, L293D motor driver IC and piggybacking L293D Motor driver IC for driving high current motor drivers. In this post, I will show you how you can design and make your own L293D motor Driver Board, that can control…
The project presented is a stepper motor/motor driver circuit board with SN754410 motor driver IC including some power saving features. The board can drive 2 DC motors or a stepper motor with the help of dual H bridge circuit in the IC. SN754410 IC is being widely used for driving motors as it operates…
Watch uses the same microcontroller as one on Arduino UNO – super hackable and easy to use! More info
