Hello Guys, Once again I have made a microcontroller Development board but this time we are using INTEL 8051. Yeah! I know it is pretty old and it is the first microcontroller I had started with. It was the 1st microcontroller of INTEL, released back...
So far I have made several weather stations that display local values as well as internet data, which you can view on my playlist. This time I will present you a way of making a very interesting desktop weather station that...
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...
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...
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...
Instructions : Step 1. Unscrew 4 small screws to open the solar compartment. Step 2. Solder your battery JST-PHR-2 connector or power wires to the + and - terminals of the battery. If you don't have the proper connector you can solder directly...
1. Concept As a practical application of my PERSEUS-9 computer for astronomical observation, I decided to create a hardware and software system to display the celestial coordinate system of an equatorial mount. This computer is not suited to perform...
Who are we? We're a team of about 100 undergraduate engineers from the University of Illinois at Urbana Champaign, and our mission is to be one of the first collegiate teams to design, build, and launch a two stage rocket 100km to the Kármán...
Mechanical Parts and Assembly https://github.com/StefansAI/JetCar/blob/main/docs/Assembly.md The documentation in GitHub and Video 1 starts with the mechanical design of the car itself in Fusion360 and goes over the assembly of the 3D-printed parts (Video...
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...
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...
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...
The M-BUS Master Wing can read consumption meters for heat, gas, oil, water etc. that have a built-in M-BUS slave interface. Features: M-Bus (meter bus) Master powered by an external 9..30V DC voltage (36V for the MBUS will be generated internally...
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...
## 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...
