3DPrinterOS Announces Sponsorship of OctoPrint to Ease 3D Printer Integration

by

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.

GameCube Sleeper Gaming / Emulation PC Build!

by

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

Should you buy a GaN Power Adapter? Or is it a scam? || Testing GaN FETs!

by

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!

How to work with a Real Time Operating System and is it any good? (FreeRTOS, ESP32)

by

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?

Cast Spells on Devices with This Magic IoT Wand

by

Sam March can now “magically” control smart outlets with a wand that detects gestures and sends them via Bluetooth.

As stated best by the writer Arthur C. Clarke, “Any sufficiently advanced technology is indistinguishable from magic.” Internet-connected homes can certainly feel like magic sometimes, as every appliance, light bulb, and outlet can all talk to each other and relay information for increased convenience and efficiency. However, just saying a command to your favorite digital assistant or pressing a few buttons on an app isn’t that fun, which is why Sam March decided to invent a novel way of activating smart outlets — through a magic wand. By performing certain gestures, the user can cast “spells” on specific outlets through Bluetooth.

Boochow’s RaspberryPi Pico Receives and Decodes MIDI Signals via Its USB Port

by

Developed using the TinyUSB library, this project receives MIDI messages via USB and decodes them for printing via UART.

Pseudonymous developer “boochow” has used the popular Raspberry Pi Pico in the heart of a MIDI device with a difference: Rather than making music, it’s designed to monitor and display the MIDI signals received from a USB MIDI device.
