Boomerang-32

Boomerang-32 is a electronics project centered around an ESP32 microcontroller. I will be adding different cool and interesting features as I go along!

Version 0.2:

• Light dependent resistor
• Mpu 6050
• buttons
• new button testing interface
• charging module
• esp32
• Lipo battery
• on/off switch

Version 0.1:

• touch sensor
• charging module
• esp32
• Lipo battery
• on/off switch

Objectives

Create a handheld electronic device that has basic functionalities such as

• 🔆dynamically changing screen brightness
• 🔋 displaying battery level
• 🎮 games
• 🤖 virtual Pets
• 🖥️ Network Monitor
• 📊 Resource Monitor
• ↔️ Interactive 3D Accelerometer display
• ...and more!

I will code everything from scratch using C++ so I can implement all the cool things that I wish to see!

milestone 1:

• ✔️ screen brightness settings persists between on/off and can be changed.
• ✔️ a basic menu that can be navigated by a button. (currently only one touch sensor, I have yet to acquire enough buttons).

milestone 2:

• ✔️ add atleast 4 buttons to the board.
• ✔️ use buttons to navigate the menu.
• ✔️ install a Light dependent resistor to adjust screen brightness according to light source.
• ✔️ replace the touch sensor with a accelerator+gyroscope module.
• ✔️ wire up all components and wrap up all hardware installation.

milestone 3:

• create a battery status indicator.
• a menu to display ambient temperature
• a menu to test button responsiveness

I will start a daily log section, if you are interested in my development process

day 3 (20/8/2024)

• I replaced the touch sensor with a accelerometer+gyroscope. I hope to use this sensor to awake the boomerang from deep sleep when the device is held up. (much like mordern smartphones)
• if the jumper wires arrive today I will complete everything in milestone #2.
• I need to implement a shorter and simpler button debounce logic wihtout compromising quality. button debounce is when a button is pressed once but makes contact with the circuit more than once, kind of like when you hit a ball once but it doesnt just hit the ground once, but multiple times before coming to a rest. This is problematic as the esp32 will interpret these bounces as additional clicks. we can use code to fix this issue, I just don't want to write long and complex logic that makes it harder to debug.

day 4 (24/8/2024)

• installed all the hardwares
• going to work on the software next time

Thats all folks (for now...)
