CONTEXT For a while now, I haven't been able to create a project outside of college. Due to the December break that had just passed, I was able to think of a weekend project (which actually took me three weekends due to several reasons) when I first...
Idea The project is meant to create yet another 'digital clock made of analog clocks', but different. So these are the main requirements for this design: Use cheap and easily available componentsSimple setup with as little parts as possibleUse overlapping...
It’s been very long, I am making circuits on PCB and breadboard. But while testing the circuits on breadboard the main problem is to make the connections and supply it with a logic power. Digital circuits can be easily made but on the other hand breadboard...
Hardware Package & Size The form of the cartridge comes naturally as it is the same as a DIN socket. It is cylindrical with same diameter as the wrapper of the connector so that it replaces it, and the length is as small as possible. Interfaces...
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....
## What is it?Project RE-birth 2nd is the spiritual continuation of [Project RE-birth](https://web.archive.org/web/20210307031049/ym2203.com) In 2021, for unknown reasons, the Japanese closed the ym2203.com website, deleted all public...
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...
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...
Design Details:- My challenge here is to use as few unique parts as possible, and to keep the BOM approachable for a casual beginner hobbyist. - I make heavy use of cloned/reusable parts wherever possible, so that instead of printing 5 different...
deepfriedneon It is a high-frequency air-core transformer that produces high-voltage, low-current, and high-frequency alternating-current electricity. In general, Tesla coils can be divided into two groups, Spark Gap, and Solid State Tesla Coils....
For the radiation detector I’m working on I had to do my first analog design. I knew it wouldn’t be very straight-forward and I’d be going back and forth between simulations in PSpice for TI and trying out circuit prototypes. The detector analog front-end...
I started this salvage project to produce a 32000-series cross-assembler that could be compiled to run on my Linux PC, and indeed any machine with a C compiler. Re-typing listings is very tedious, but one can use OCR to do much of the work. It is still...
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...
This project is designed to for kids. My meetings are usually about 1 hr 30min long, this project will take four meetings. I have a group of about 10 kids participating. There is a lot of soldering, I get parents to help. I can...
