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...
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...
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...
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-...
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...
EC11-rotary-encoder-the-easy-way (on a single mcu input pin) As rotary encoder without push button what do we need 1x ATTINY45 2x 4K7 1x 10K 1x EC11 We have 2 options for the connection to the main MCU with 2 outputs 1x pulse output when turning right...
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...
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...
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...
The delta calibration guide for klipper recommends a 0.025 mm consistency or better for automated probing. Testing of this probe location bias on my FLSUN QQ-S Pro with the stock magnetically attached probe showed the bias was at least an order...
Supplying power.One of the trickiest parts was finding a small 5V WW/CW LED controller. Most were 12-24V and I did not want to ruin a 200 dollar lamp. Any LED controller should work, but make sure that you are using 5V, and that the controller supports...
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...
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...
