ESP32 Agent Dev Kit is an LLM-powered voice assistant built on the ESP32-S3 platform (Crowdfunding)

The ESP32 Agent Dev Kit is an ESP32-S3-powered voice assistant that offers integrations with popular LLM models such as ChatGPT, Gemini, and Claude. Wireless-Tag says the Dev Kit is suitable for “95% of AIoT applications, from smart home devices to desktop toys, robotics, and instruments” In some ways, it is similar to the SenseCAP Watcher, but it has a larger, non-touch display and dual mic input. It however does not support local language models. It also features a standard MikroBUS interface for expansion. For voice capabilities, the ESP32 Dev Kit integrates two onboard, noise-reducing microphones and a high-fidelity speaker. The built-in infrared laser proximity sensor detects human proximity and movement for “smart interactive experiences”. ESP32 Agent Dev Kit specifications: MCU – ESP32-S3 dual-core Tensilica LX7 microcontroller @ 240MHz, 8MB PSRAM Storage – 16MB flash Display – 3.5-inch Touchscreen, 480×360 resolution Camera – 5MP OmniVision OV5647 camera module, 120° field of […]

BANDIT PC32 standalone ColorForth keyboard computer is powered by the Raspberry Pi RP2350 microcontroller

BANDIT PC32 is a Raspberry Pi RP2350-powered keyboard computer that runs a graphically-oriented version of the ColorForth programming environment. The BANDIT PC32 is primarily aimed at on-the-go use for programming video games. The custom, 32-key split keyboard takes up most of the build, with a 3.2-inch 320 x 240 capacitive display in the center. It also features an HDMI port for connecting a larger external display. The 48-pin GPIO is divided into two female headers and can be used to interface with other devices directly. This is the second version of the Bandit standalone computer, building on an early prototype based on the RP2040 microcontroller. We have seen several interesting RP2350-based products like the Inky Frame 7.3”, 4D Systems display modules, and Jumperless V5 programmable breadboard. However, this is the first RP2350 standalone computer we have come across. It shares some similarities with the ESP32 Rainbow. BANDIT PC32 ColorForth specifications: […]

Home Assistant-compatible 60GHz mmWave radar sensor features a built-in IR blaster (Crowdfunding)

The eMotion Ultra is a Home Assistant-compatible 60GHz mmWave radar presence sensor with a built-in IR blaster with a 15-meter range, a brightness sensor, and a temperature/humidity sensor. It is powered by an Armv8-M KM4 microcontroller with built-in Wi-Fi connectivity and is targeted at simplifying complex smart home setups. The eMotion Ultra 60GHz mmWave radar presence sensor module is reported to be able to “cover up to 40 square meters (430 square feet) using just one device.” It can be configured for up to 4 zones with personalized automations for each zone. The exact Armv8-M KM4 module used isn’t named but is likely based on a Realtek RTL8720CM wireless SoC or other Realtek Ameba microcontroller. Potential applications include security management, lighting automation, home climate control, energy management, and rental property management. We have seen similar presence sensors such as the RoomSense IQ, Seeed Studio’s mmWave fall detection kit, SONOFF SNZB-06P, […]

OpenFlexture Microscope is an open-source, 3D-printed microscope based on Raspberry Pi 4 SBC and Camera Module v2

The OpenFlexture Microscope is a DIY, open-source, 3D-printed microscope built around the Raspberry Pi 4, a Raspberry Pi Camera Module v2, and a choice of optics or various qualities up to lab-grade optics. It can be motorized using low-cost geared stepper motors and can achieve a resolution of up to around 100 nanometers I found out about the OpenFlexture Microscope in one of the sessions at the upcoming FOSDEM 2025 event whose description partially reads: The OpenFlexure Microscope is an open-source laboratory-grade digital robotic microscope. As a robotic microscope, it is able to automatically scan microscope slides creating, enormous multi-gigapixel digital representations of samples. The microscope is already undergoing evaluation for malaria and cancer diagnosis in Tanzania, Rwanda, and the Philippines. As an open project, our key goal is to support local manufacturing of microscopes in low-resource settings. [..] high-quality consistent documentation has enabled thousands of microscopes to be built […]

GuRu’s modular wireless power transfer system can power a drone indefinitely

California-based company GuRu Wireless has recently developed and showcased a scalable and modular wireless power transfer system that is capable of delivering power to a high-power device up to several kilowatts, such as a drone, from up to 30 feet away (a little over 9 meters). They also mention that the system can power low-power devices, like LEDs and consumer electronics, over distances of several kilometers. It’s quite an extension to the GuRu’s desk-range wireless power evaluation kit we covered in 2020. The system uses 24 GHz high-frequency millimeter-wave radio signals to deliver energy over long distances without needing batteries or tethered systems. GuRu’s system uses a phased array transmitter with proprietary RFICs, to precisely deliver power to the receiver called the Recovery Unit (RU). In a recent demonstration video, GuRu Wireless showcased their wireless power transfer system by powering a drone from 30 feet away, operating it continuously for […]
