The way a pellet extruder works is that the pellets are pushed into a hot zone where they melt and are then pushed through a nozzle. In injection moulding it is pushed into a mould. In my case, I wanted to make this nozzle a 3D printed one. By looking...
Where it all started: In late 2023, Chamberlain started blocking the MyQ garage door integration from Home Assistant. This move confirmed my concerns about relying on integrations that communicate through cloud based APIs. I begrudgingly overcame MyQ's...
This is very much a work in progress and most of the requirements are not satisfied yet. But thanks to excellent documentation done by NuclearPhoenix on the All-In-One Gamma-Ray Spectrometer and the Cosmic Pi project I have a proof of concept working.Pomelo...
Intro Hello. I've come up with a groundbreaking idea. It's a USB C-Type Connector that can handle both USB and Ethernet communications. As shown in the above image, I'm looking to create an incredibly compact board by combining the Raspberry Pi Pico...
Key points- Runs off 4 LXT 18V battery packs- 1500W output (3kW peak)- 360Wh capacity with 5Ah packs (432Wh with 6Ah packs )- Fits in a large MACPAK case (otherwise known as Type 3 or Mbox3) Planned upgrades- Individual battery pack voltage/current monitoring-...
In practice, we very often need to measure low resistances. Measuring low-value resistances, especially those less than 1 ohm, is nearly impossible with a standard multimeter. On the other hand, an commercial milliohmmeter instrument is...
Processor This is a 4GB Raspberry Pi 4 Model B. Initially, I used an SD card for storage but have now upgraded to an Integral 120GB USB connected SSD. This really improves the startup time for applications but has an impact on battery life as outlined...
Mario Kart Wii is a great game, but the controls are awkward. So, I built an alternative controller to play the game with a D-pad. How It Works A Lego base with a rotating platform was built. The Wiimote sits on the rotating platform and is turned by...
Improvements before next batch: - Change the CC orientation LED design to: (A side) STD [FLIP] (B side) STD [FLIP] (still 4 LEDs but now 2 indicators at a time)- Low power mode / power time off to save battery - Remove DIP switch for...
Introduction A WiFi smart button is a simple yet versatile device that leverages the capabilities of the ESP8266 (or similar modules) to connect to a WiFi network and communicate over MQTT (Message Queuing Telemetry Transport) to perform specific actions....
Step One: Print the Enclosure I did 4 outer shells and 20% infill to help ensure the enclosure would not be prone to bending over time. Step Two: Set Your Servo to Neutral Plug in your servo to the Arduino Uno and upload the Servo Neutral sketch. This...
Nevertheless, there are still a few grand challenges to overcome while applying mechanical anomaly detection to mass production operations, such as the scarcity of data sources leading to false positives (or negatives) and time-consuming (or computationally...
The basic idea behind PEMF is that it can influence the body at the cellular level, promoting healing and regeneration. The electromagnetic fields generated by PEMF devices can penetrate the body and interact with the cells, tissues, and organs. PEMF...
Background Floods pose a significant threat to communities, infrastructure, and the environment. Timely and accurate flood monitoring is crucial for early warning and effective disaster management. In this context, Internet of Things (IoT) technologies...
Hi. So this is the story: My interest/knowledge of embedded stuff was always around 32bit MCUs and a little bit of FPGA/CPLD devices. Mostly in audio signal processing world. The embedded Linux always was for me something out of my scope. Back in the...
