Screenshot of Vectron VGA Plus running a demo: How It Works I previously built a massive 7400-logic based VGA generator called Vectron VGA. While it was a nice project to build, it is huge, and not very practical to keep around for use in...
Some design goals: Use a 555 central to the design, with minimal additional circuitry.Keep it simple. A real-life implementation should add under voltage lockout for the load and over and under-temperature lockout for charging, but adding these...
Introduction In this project, we are going to make a simple lipo battery charger using TP4056 module with battery protection. The circuit that charges the battery by supplying the charge carrier (i.e-electrons) to it is battery charger circuit....
The project is about building a robot capable of playing beer-pong, for which it has been decided to implement a catapult that is capable of launching a pingpong ball into a cup located one metre away. For which two sub-systems have been implemented,...
HIGH VOLTAGE: HAZARD OF ELECTRICAL SHOCK. WARNING: This equipment should be installed, adjusted, and serviced by qualified electrical maintenance personnel familiar with the construction and operation of the equipment and the hazards involved. Failure...
Hardware: ESP01 module (ESP8266) attached to a ESP01 LED shieldA neopixel (ws2812) LED connected to the GPIO2 of the ESP moduleA small servo (S0006/MG996) connected to the GPIO0 of the ESP moduleCapacitor; maybe not really necessary. I took the biggest...
Backstory In 2019 I made a gadget called Blue POT that let us use an old 1945 rotary telephone we had with our cellphones. It was fun but suffered from some issues. Audio levels weren't great, there was noise and configuring the BM64 bluetooth...
To begin this project I'd like to give an overview of the process of charging Lithium batteries of various chemistries. There are two primary phases in charging a lithium battery: A Constant Current phase (CC), and a Constant Voltage phase (CV). A discharged...
Our project had a planned development timeline of 11 weeks, consisting of 6 milestones. Milestone 1 consisted of defining project goals, researching components and ordering parts. During this milestone we developed our proposal, "to create a...
Tg: Tg means "glass transition temperature", if we pass the Tg temperature of a PCB then the PCB substrate will go from being a hard glassy structure to a malleable rubber structure, this can ruin the PCB's mechanical performance and would crack/break...
This is an example output of the RRT algorithm with a 5-link serial manipulator. This is an example output of the PRM algorithm with a 5-link serial manipular. The overall structure of all functions used in the task 1 code is outlined in figure 1 where...
In this project, we are trying to drive a BLDC motor in very low speed. This means we need to have a very low PWM values update rate. However, the PWM values update rate is constant, the rotating speed of motor's rotor may not being what you expected....
If I asked you: could you please turn off the lights when it comes to 10:30? Actually, the common answer would be check your smartphone and make a reminder on your phone to turn the lights off by 10:30. Well, that's ok for any normal person, but not...
So this is R2Home: a fully autonomous, and flight proven GPS guided recovery system. But how do we get there, and what is important to get a working R2Home? The general idea we want to reach. Main details : R2Home is composed of few...
A Chaser Circuit consists of a clocked IC or other electronic unit like an Arduino that drives an array of LEDs in such a way that individual LEDs (or small groups of LEDs) turn on and off in a predetermined and repeating sequence, thus producing a...
