Capyboard, ESP32 Development Board for Education by emiler

Capyboard is an ESP32 development board built to accept individual custom-made modules. The board is created primarily for use in education, where you want to focus on embedded programming instead of spending time with connecting cables and parts on a breadboard, as you would with Arduino and other such devices. The board is not limited only to education and it can be used to build, for instance, a very powerful internal meteo-station and so on.

• github.com/realcharmer/capyboard-starter
• github.com/realcharmer/capyboard-docs
• github.com/realcharmer/capyboard-examples
• docs.capyboard.dev

Hack Week 25

My plan is to create a new revision of the board with updated dimensions and possibly even use a new ESP32 with Zigbee/Thread support. I also want to create an extensive library of example projects and expand the documentation. It would be nice to also design additional modules, such as multiplexer or an environment module.

Goals

• Implement changes to a new board revision
• Design additional modules
• Expand documentation and examples
• Migrate documentation backend from MkDocs to Zensical

Hack Week 24

I created a new motherboard revision after testing my previous prototype, as well as a light module. This project was also a part of my master's thesis, which was defended successfully.

Goals

• Finish testing of a new prototype
• Publish source files
• Documentation completion
• Finish writing thesis

ESPClock: An open-source smart desk clock with Home Assistant integration by jbaier_cz

Description

ESPClock will be an open-source, Wi-Fi connected digital clock powered by ESP32 and ESPHome, designed to seamlessly integrate with Home Assistant. Featuring a 3D-printable case, the clock combines modern style with smart home functionality.

Goals

Key features:

• real-time clock
• native Home Assistant integration
• optional sensors for temperature, humidity and ambient light
• custom 3D-printable case
• open-source firmware and hardware design
• easy YAML-based configuration

The Hacking

Chapter 1: Inventory

After thoroughly inspecting my closet, I managed to gather a handful of useful components. I decided to keep things simple and avoid making the project unnecessarily complex, opting for ready-made modules instead of assembling everything from individual parts. This approach saves time and reduces the chances of compatibility issues. The components I settled on are:

• Microcontroller: ESP32-LPkit
• 4-digit 7-segment display with integrated controller: TM1637
• Temperature and humidity sensor: DHT22
• Carbon dioxide sensor: MH-Z19
• PIR motion sensor: AM312
• Illumination sensor: VEML7700
• I2S-compatible microphone module: SPH0645LM4H
• A couple of micro switches
• A few LED diodes with appropriate resistors

With this list, the essential environmental parameters should be well covered. The clock’s main function—displaying the current time—is handled by the bright 0.56-inch display. Additionally, the setup provides simple input options through buttons and possibly even voice commands in the future.

Chapter 2: Wiring Diagram

I went through the datasheets for all the components to determine the most effective way to connect them. After comparing different options and checking for compatibility, I finalized the following wiring diagram.

Chapter 3: Firmware

For the software part, I decided to use ESPHome, which offers an easy and reliable way to integrate the clock with Home Assistant. All the components from the inventory are natively supported, so there is no need to write much additional code.

The following example shows how the YAML configuration for the clock may look: espclock.yaml
