Have you dreamed of combining the two incredible activities putt-putt and Connect Four together into the same game? Well one daring maker set out to do just that. Bithead’s innovative design involves a mini golf surface with seven holes at the end corresponding to the columns. The system can keep track of where each golf ball is with an array of 42 color sensors that are each connected to one of seven I2C multiplexers, all leading to a single Arduino Uno.
This open source analyzer comes with an easy-to-use setup and tests each and every parameter of a stepper motor.
If you have a 3D printer and want to analyze the stepper motor signals without the use of a computer and expensive stepper analyzer, then this low-cost hardware design can solve your problem. The open source analyzer comes with an easy-to-use setup and can be easily built to give you the capabilities to test each and every parameter of the stepper motor.
Lios Design, a team formed by MIT students, is well on its way to perfecting molten glass 3D printing.
The vast majority of 3D-printed objects are plastic. Most FFF (Fused-Filament Fabrication) 3D printers use thermoplastic filament and LCD/SLA (Stereolithography) 3D printers use photopolymer resin. Other materials, like ceramic, concrete, and metal, are somewhat common. We’ve even seen organic tissue and various foods being 3D-printed on occasion. But glass is difficult to print, because of the temperatures required and the physical properties of molten glass. That’s why it is impressive that Lios Design, a team formed by MIT students, is well on its way to perfecting molten glass 3D printing.
Back in 2009, as part of a publicity stunt for… Big Family Games, publisher THQ commissioned the creation of a golden Nintendo Wii, and had it delivered to Her Majesty Queen Elizabeth II.
The Queen likely never received the console—as outlined in this excellent episode of People Make Games—but it did eventually find its way into the hands of collector Donny Fillerup, one of the guys behind the website consolevariations.com, which I wrote about back in 2019.
Software developer 3D Control Systems, the parent company of 3DPrinterOS, has become a corporate sponsor of open source interface OctoPrint to help ease 3D printer integration processes.
Through its 3DPrinterOS platform, the company will help users and companies integrate Octoprint into their 3D printing workflows by means of its new 3D Printer Software Development Kit. By offering integration as a software service, the partners are hoping to save customers time and money on developing their own software to fully integrate OctoPrint with their systems.
A thimble which, thanks to a GY-521 and an Arduino Leonardo, is able to control the mouse pointer.
I Turned a GameCube into an awesome small form factor Sleeper gaming PC and it was way easier than I thought it would be! This thing turned out great, Powered by an 11th gen i5 Tiger Lake 1135G7 backed by 16Gb of DDR4 ram and built-in Intel Iris Xe graphics plus we have the option to add an external Video Card “eGPU” because this Gamecube now have Thunderbolt! It’s Perfect for Emulation and can handle Dreamcast, Gamecube, and Wii using the Dolphin emulator up to 4K, PS3 using RPCS3, and even CEMU for Wii U
In this video we will be having a closer look at GaN FETs in order to find out whether they will improve power electronics products in the future. For that I got myself a commercial GaN power adapter which I will compare with a more traditional power adapter concerning their efficiency. Afterwards I will measure the resistance and switching speed of a proper GaN FET and finally use it in a buck converter circuit to demonstrate the difference to a normal MOSFET. Let’s get started!
Using a real operating system to simplify programming with the Arduino IDE. Is this possible and how? Let’s have a closer look!
Operating systems were invented to simplify our lives. But, because they need a lot of resources, they only run on reasonable computers like the Raspberry Pi or a PC. Right? Wrong. Nowadays, we also get operating systems running on our small MCUs. Particularly interesting in this respect is the ESP32 because it has enough power and memory to accommodate such an additional burden. And the best: It already runs a version of FreeRTOS with all our Arduino sketches, and it is easier than you think. Is this useful?
