ESP32 based Open Source 3D printer supports MSLA resin
CrowdSupply recently featured the Lite3DP Gen2 which is a miniature MSLA resin 3D printer built around a ESP32 module from Espressif. This product supports all UV 405-nm resins and it can be configured with optional displays for real-time print progress.

Arduino compact board equipped 9-axis IMU and supports TinyML
The Arduino Nano 33 BLE Sense Rev2 is an embedded platform featuring the NINA-B306 module (nRF52840 SoC) from u-blox. In addition to wireless support (BL + Zigbee), the new Sense Rev2 combines a 6-axis gyroscope/accelerometer sensor, a 3–axis magnetometer and various other sensors for data acquisition.

KiCad 2022 End-of-Year Recap And 7.0 Preview
[Chris Gammell] moderated the KiCad 2022 End-of-Year Recap with several KiCad developers and librarians. They reviewed what’s been bubbling up in the nightly KiCad 6 builds, what we can expect from KiCad 7, and even answered some questions from the user community. Over the course of 2022, the KiCad project has grown both its development team and library team. The project even has a preliminary support commitment from the CERN Drawing Office!

Battery-Powered ESP8266 Sensor? Never Been Simpler
Say, you’re starting your electronics journey with a few projects in mind. You have an ESP8266 board like the Wemos D1, a Li-Ion battery, you want to build a small battery-powered sensor that wakes up every few minutes to do something, and you don’t want to delve into hardware too much for now. Well then, does [Mads Chr. Olesen] have a tutorial for you! Here, you’ll learn the quick and easy way to get your sensor up and running, learn a few tricks for doing sleep Arduino environment, and even calculate how long your specific battery could last.

Want To Play With FPGAs? Use Your Pico!
Ever want to play with an FPGA, but don’t have the hardware? Now, if you have one of those ever-abundant Pi Picos, you can start playing with Verilog without getting an FPGA board. The FakePGA project by [tvlad1234], based on the Verilator toolkit, provides you with a way to compile Verilog into C++ for the RP2040. FakePGA even integrates RP2040 GPIOs so that they work as digital pins for the simulated GPIOs, making it a significant step up from computer-aided FPGA code simulation
