Android Vinyl Action Figure Automation
Ávila de Oliveira Sep 20,2022
IntroductionI had two Android characters like the one shown following and I thought: Is it possible to attach some mini motors and automate it? Spoiler alert: Yes, It is possible!Let's go for it!The brand new Android Vinyl Action FigureAndroid Figure setupFirst, I had to carefully open the little toy to make room for the three motors and the two RGB LEDs. One motor drives his head, and the other two motors drive his arms and LEDs to his eyes. At first, I thought it would be impossible, due to th...

Bluetooth Audio Receiver + Pop Noise Remover for Amplifier TPA3116D2 2.1
Lutfi Sep 16,2022
In this article I will make a special audio receiver bluetooth module for the TPA3116d2 2.1 Amplifier (then I will call TPA3116d2). I call it special because the design of this module is based on the PCB TPA3116d2. To see the design of this module, you can see the top module in the image above.The TPA3116d2 produces pop noise when first turned on. So I added pop noise remover in bluetooth module which i will make in this article.Overall, the module that I will make has two functions that are qui...

Fall Detection client-server system with Machine Learning
Bandini Sep 12,2022
Falls could be dangerous in any situation but for certain working scenarios, consequences are definitely worst, therefore came the idea of developing a Machine Learning fall detection/report system. Each worker has a small TinyML device in charge of detecting falls with accelerometer data and reporting to a server through Bluetooth. The server is a Raspberry Pi running a Python script that scans specific BT announcements, parse fall information and store it into a SQL Lite database for reports a...

Smart Basketball Scoreboard
Ávila de Oliveira Aug 08,2022
IntroductionI do basketball training workouts regularly and always track the sections' statistics (number of shots, scores, misses, etc). Track these numbers is kind of boring and hard to accomplish. The smart balls can be used for this but they have some drawbacks:If you want to train with multiple balls you'll need to buy several (expensive) smart balls.The accuracy isn't so good.The durability of the ball.Let's go for it!Versions1.x.xAt the beginning of the project, I used the hardware compon...

Machine Vision Trip WIre | Switch App when Motion Detected
SimonX Jul 28,2022
IntroductionWanna slack off abit but scared to be busted? Here is the all-in-one wireless tripwire that help you automatically switch your computor program when motion is detected! Best of all, it uses MicroPython to program OpenMV so you can even add some "whitelist" using face recognition, and it also use RTL8722DM_MINI as the Bluetooth Keyboard, so you can even trigger a custom script upon motion detected~??DemoProject DetailsA hearty combination of "Machine Vision" and "Bluetooth HID" functi...

Bluetooth Controlled LEGO Toy Car
Hernando Jul 12,2022
MotivationMy motivation was my kids. I want to share time and have fun with them teaching them some basic concepts about projects and electronics.As PM I assigned some tasks for one of them in this project: to build a Lego car to be used for installing the Arduino board, the wheels and motors coupled and space to install 9V batteries. This mission was given in a piece of paper and a specific date was established. My intention is to use this experience in the near future for a GO-KART protot...
