When I completed my review of Raspberry Pi Zero 2 W, I mentioned I would test the power consumption of the board later. It took a while, but I’ve finally come around it using Otii Arc from Qoitech and Otii software to provide some pretty power consumption charts, and even energy consumption. Since the Raspberry Pi Foundation recommends a 5V/2.5A power supply, I’ll first try to get as close as possible as 2.5A, then I’ll go through tricks to reduce idle power consumption to less than 75 mA / 375 mW, and finally check the energy consumption under various CPU core count and frequency. Raspberry Pi Zero 2 W Power consumption under load, with accessories I started with the latest Raspberry Pi OS Lite “Bullseye” image and connected my Raspberry Pi Zero 2 W board to Qoitech Otii Arc tools as shown below. It used to cost around $500, but […]

PicoVoice offline Voice AI engine gets free tier for up to 3 users
PicoVoice offline Voice AI engine has now a free tier that allows people to create custom wake words and voice commands easily for up to three users on any hardware including Raspberry Pi and Arduino boards. I first learned about PicoVoice about a year ago when the offline voice AI engine was showcased on a Raspberry Pi fitted with ReSpeaker 4-mic array to showcase the company’s Porcupine custom wake word engine, and Rhino Speech-to-Intent engine. The demo would support 9 wake words with Alexa, Bumblebee, Computer, Hey Google, Hey Siri, Jarvis, Picovoice, Porcupine, and Terminator. More importantly, the solution allows you to easily create your own custom words in minutes from a web interface by simply typing the selected wake word, with no need for hundreds of voice samples or waiting weeks to get it done. So I tried “Hey You” first, but I was told it was too short, […]
Review of an ESP32-based BLE to MQTT gateway – Part 1: GL.inet GL-S10 unboxing and teardown
GL.inet introduced the GL-S10 BLE to MQTT IoT gateway last month with an ESP32 module offering WiFi and Bluetooth connectivity, as well as Ethernet and PoE support. I got offered a sample for review, and just received it together with the optional BLE beacon. So today, I’ll first have a look at the content, and check out the hardware with a teardown. GL.inet GL-S10 unboxing The package shows us the main features with Bluetooth LE 4.2, WiFi, PoE, and external antenna, with GL-S10 described as a BLE IOT GATEWAY connecting IoT devices to the Cloud. The gateway ships with a getting started guide, an antenna, a USB cable for power, as well as the beacon which we can see with a 3M stick tape. On one side, we have the RJ45 connector for Ethernet and a micro USB port for power, while the other side features a reset button, plus […]
