Two things that inspire an electronics hacker are cheap micros and GRB leds like the WS2812. There are many drivers for them, including WCH's CH32V003 RISCV chip (about $0.14 for the SOP 8 version in 500's).But, most drivers I have seen use bit-banging...
But how to make the shape? I saw there are a lot of such things using pepakura techniques, but that assumes 0 thickness. So I wrote a Python script for Blender to compute the faces. (it fails a some edge-cases, but those can be fixed with a rotary tool)...
Meaning of Saturation Current The current handling capability of these inductors is not dictated by the max current the coils of wire can take before getting too hot, but by the max magnetic field the core of the inductor can support. For ferrite core...
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...
Numerous studies have shown that flickering, although high frequency and then totally invisible, It can also cause headaches, eyestrain and nausea. Incandescent, halogen or fluorescent lamps (as well as LED if poorly designed), turn on and off a hundred...
Niklas from Advanced Tinkering will host the Hack Chat on Wednesday, March 6 at noon Pacific. Time zones got you down? Try our handy time zone converter. To the casual observer, there's not much that goes on in experimental physics that doesn't require...
I will say this DF2301 is a smart sensor, not because it has some AI or Internet models working inside. Because this sensor is capable of giving you the essence of new generation Machine learning models. Running on a small microcontroller it is able...
⚠️ DISCLAIMER ⚠️ Please be aware that as of the current version, there is a significant issue when using several modules together, primarily due to the way the interrupt is implemented. For more detailed information,...
Why is it missing one of the 2 PSUs? I have a tradition in my work. Every time I issue a first revision of the board, I have to mix up polarity in some place. This applies even to smallest projects, like this one. Took some effort, but I managed to do...
ARPS Overview ARPS (Arduino®-compatible Robot Project Shield) is beginner-friendly add-on shield for the popular Arduino UNO R3 and Arduino UNO R4 circuit families. ARPS is designed to help new learners focus on rapidly developing their programming...
In the previous tutorial we discussed the word organization, setup and configuration of DF2301 Offline voice recognition module. Today we will make a home automation project using the same module with Solid state relay interface for small loads. But...
A 6-ch 230V mains underfloor heater valve controller with 6 mains inputs, based on an ESP32S3. - 6 AC inputs for reading the wall thermostates as fallback (no WiFi/ HomeAssistand dies)- 6 AC outputs using Optotriacs (max. 1,2A / channel)- UART & I²C...
Adding project details, etc. over time as I reverse engineer my own project! Here are some specs of this machine: Customized Desktop / Workspace environment to honour the Z88 UIBuilt-in Application Suite to provide modern alternatives to the Z88...
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...
1. Autosampler as a substitute for a multi-way valve As the FIA valve system is very difficult for the hobbyist to reproduce, I decided to replace the valve with an autosampler. An autosampler is commonly a device that is coupled to an analytical instrument...
