The host of The Electromaker Show reviews the February Electromaker of the Month winners, including a LoRa walkie-talkie by Kutlahan Akta, and celebrates the 10th anniversary of the Raspberry Pi. He discusses a faithful Sol-20 retro computer recreation using a Raspberry Pi, reviews the Blues Wireless Notecard for cellular IoT, and highlights a Cornell University project for silent voice command recognition via lip reading.
The host discusses stretchable PCB research from Yale's Faboratory and Charles Lohr's PolyLMN project, which use liquid metal pastes to create circuits that stretch up to 4x their size. He covers the potential Raspberry Pi 500 keyboard computer, the Pimoroni Pico Plus 2 W featuring the new RP2350 chip and in-house RM2 Wi-Fi module, and the M5Stack Cardputer ESP32 devkit. The episode also highlights the ESP32 Rainbow ZX Spectrum on Crowd Supply, solderless PCB prototyping with Opulo's Lumen PNP, and the ethical resolution of Jeff Geerling's voice cloning incident by Elecrow.
The host reviews several maker projects, including Eamon Magd’s automated Stroop Waffle system using OpenCV and an ESP8266-based One Ring home automation notification device. He highlights the GenBook RK3588 modular ARM laptop and the Zerowriter e-ink typewriter on Crowd Supply, then benchmarks the new $50 Raspberry Pi 5 2GB variant against higher-RAM models. Finally, he covers Adafruit’s move to Industry City in Brooklyn and their new Metro RP2350 board.
The host of The Electromaker Show reviews several maker projects, including Kevin's Pi Day synthesizer, Graham Sanderson's DOOM port on the RP2040, and Daniel Bell's DIY Spacemouse. The episode also covers crowdfunding updates for the Halo TD-XPAH Wi-Fi 6 board and the SoCORAD32 amateur radio, alongside a deep dive into Ben Vallack's custom ergonomic keyboard and Neil's Pockit modular computer with its new CM4 upgrade.
The host covers OpenCut, an open-source quadruped framework by Petoy using the Arduino-based Nyboard, and two Low Level Learning tutorials on using embedded Rust with the Raspberry Pi Pico and Arduino Uno. He highlights a modular synthesizer project by Joshua Coleman controlled by an Apple II via a DAC, and Iran Fiet’s Atari 2600 tennis interface. The episode concludes with news on the Mico RP2040 USB PDM microphone, the new Raspberry Pi network-bootable bootloader, and updates to the Arduino CLI and CadQuery CAD tool.
