🎛 Insanely Small Development Board: T402 Atto
It’s an extremely simple circuit and hardly something that hasn’t been done before, but the value here is in the tricky soldering to make it rather than its novelty.
The ATtiny402 and three passive SMD components are fitted on the smallest possible sliver of prototyping board to contain them, and the female headers and set of programming pins contribute far more to the volume of the device than the board itself. He also tried a side-on design with two smaller slivers of board before settling on the more conventional layout.
The demonstration of the system in action seen in the video: the break is a magnetic flux detector, dwarfed by the 40-pin DIP Z80 it is sitting on.

🎥 ESP32-CAM Video Streaming Web Server
In this project we’re going to build an IP surveillance camera with the ESP32-CAM board. The ESP32 camera is going to host a video streaming web server that you can access with any device in your network.
You can integrate this video streaming web server with popular home automation platforms like Home Assistant or Node-RED. In this tutorial, we’ll show you how to integrate it with Home Assistant and Node-RED.

📺 30 FPS FLIP-DOT display controlled by ESP32
The article describes the process of development of a novel type of display (which has a lot of advantages) based on magnetic induction and the way it can be controlled by ESP32 microcontroller.
There are tiny magnets hidden inside each flat dots. Basically, to flip a dot, you have to flow an electrical current into the coil, generating a magnetic field around it. The direction this current flows will flip the dot from one position to the other. Only a short pulse of current is needed. The electromagnet core stays polarized, keeping the dot on position, even when the power is gone.

📟 ESP32 Deep Sleep mode using Arduino IDE
This article is a complete guide for the ESP32 Deep Sleep mode with Arduino IDE. We’ll show you how to put the ESP32 into deep sleep and take a look at different modes to wake it up: timer wake up, touch wake up, and external wake up. This guide provides practical examples with code, code explanation, and schematics.
Having your ESP32 running on active mode with batteries it’s not ideal, since the power from batteries will drain very quickly. If you put your ESP32 in deep sleep mode, it will reduce the power consumption and your batteries will last longer.

🎛 Tiny 2040 – Pimoroni
Pimoroni has officially launched its Tiny RP2040, an ultra-compact competitor to the Raspberry Pi Pico.
The Tiny 2040 uses the same Raspberry Pi RP2040 microcontroller as the Pico, running its two Arm Cortex-M0+ cores at the same 133MHz+ clock speed and with the same 264kB of static RAM (SRAM). From there, the two diverge considerably: The Tiny 2040 is an ultra-compact design the size of a UK postage stamp with 12 general-purpose input/output (GPIO) pins, an on-board switch, user-controllable RGB LED, and 8MB of quad-SPI flash with execute-in-place (XIP) capabilities.
Specifications:
▫️ Powered by RP2040
▫️ ARM Cortex M0+ running at up to 133Mhz
▫️ 264kB of SRAM
▫️ USB-C connector for power, programming, and data transfer
▫️ 8MB of QSPI flash supporting XiP
▫️ User controllable RGB LED
▫️ Twelve IO pins (including four 12-bit ADC channels)
▫️ Switch for basic input (doubles up as DFU select on boot)
▫️ On-board 3V3 regulator

🔭 Laser Projected Asteroids on the ESP32
The article (with video) describes the process of recreating of classic old game for laser projection using esp32 controller. The project includes both schematics and explained software part with detailed explanations. The game is implemented using the Esspressif IDF using PlatformIO to build and deploy.
"All in all, it's a pretty successful project. Even with my very low power 5mw laser, I can get around 2m x 2m projection at a good brightness in a dark room."
