RAKwireless announces 14 new WisBlock modules for IoT prototyping

Rakwireless has added 14 new Wisblock modules to the WisBlock IoT modular system introduced last year, plans to soon release a Raspberry Pi RP2040 based LoRaWAN Wisblock Core module, and will give away some Wisblock starter kits this week. As a reminder WisBlock IoT modular system is comprised of four block types: WisBlock Base – A carrier board with connectors for other block types, power supply, some ports WisBlock Core – Module with a microcontroller/processor WisBlock Sensor – Modules with environmental sensors, motion sensors, ambient light sensors, or others WisBlock IO – Adds more inputs, outputs, or connectivity options including LTE-M / NB-IoT, cellular and Wi-Fi modules, NFC reader, and interfaces for I2C, UART, ADC, and GPIO. New WisBlock IO and Sensor modules Some modules are available right now, while others have been announced, but just coming soon Here’s a list of the 10 modules available now: RAK12002 – RTC […]

Posture correction smart sensor helps you sit or stand upright

It’s easy to adopt a bad posture either while sitting in front of a computer or while walking and your mobile, and over time this may lead to unaesthetic and/or painful postural disorders. To solve this issue, a posture correction smart sensor may be used in place of a posture belt with what looks like a GPS tracker placed on the back of the patient, and which notifies bad postures by vibrating and to your smartphone depending on a user-configured angle range. Specifications listed for the posture-correction-smart-sensor: Sensor – Unnamed Bosch gravity sensor Connectivity – Bluetooth 4.2 Misc Medical-grade gel patch to attach the device to the bag Vibration motor Battery – 200mAh; 30 minutes charge good for about 5 days when using it for about 8 hours per day Dimensions – 6 x 4 x 1.2 cm Weight – 16 grams. The device ships with a micro USB cable […]

Raspberry Pi CM4 based Exo Sense Pi multi-sensor device gets optional earthquake sensor

Sfera Labs’ Exo Sense Pi is a device with multiple environmental sensors based on the 2GB version of the Raspberry Pi CM4 module designed for residential and commercial applications such as environmental monitoring and data gathering, BLE positioning, indoor people and assets tracking, rooms management and access control, voice control, and more. The Exo Sense Pi devices include optional WiFI 5 and Bluetooth 5.0 LE connectivity depending on the RPI CM4 module selected, and ships with temperature, humidity, air quality (VOC), light intensity, microphone, and PIR motion sensors by default, but there’s also an optional earthquake sensor. Exo Sense Pi specifications: SoM – Raspberry Pi CM4 (16GB eMMC flash) or CM4 Lite module with 2GB RAM by default. But obviously compatible with other models. Storage – MicroSD card socket for CM4 Lite module Wireless connectivity – 2.4 GHz, 5.0 GHz IEEE 802.11 b/g/n/ac wireless; Bluetooth 5.0, BLE depending on installed […]

Crowbits Master Kit Tutorial – Part 2: ESP32 intrusion scanner and visual programming

I started Crowbits Master Kit review last month by checking out the content, user manual, and some of the possible projects for the ESP32 educational kit including a 2G phone and a portable game console. For the second part of the review, I’ll go through one of the lessons in detail, namely the intrusion scanner to show the whole process and how well (or not) it works. Let’s go to Lesson 5 directly, although I’d recommend going through the first lessons that provide details about the hardware and visual programming basics using Letscode program, which is basically a custom version of Scratch for Crowbits The user manual introduces the project, explains it is to detect intruders, and lists the learning goals as we’ll learn how to control the servo and play music on the Crowbits kit. Kit Assembly But first, we’ll have some assembly to do, in a similar way […]

Raspberry Pi CM4 based predictive maintenance gateway features Google Coral Edge AI accelerator

Techbase IModGate-AI predictive maintenance gateway

Techbase had already integrated the Raspberry Pi CM4 module into several industrial products including Modberry 500 CM4 DIN Rail industrial computer, ModBerry AI GATEWAY 9500-CM4 with a Google Edge TPU, and ClusBerry 9500-CM4 that combines several Raspberry Pi CM4 modules into a DIN Rail mountable system. The company has now announced another Raspberry Pi Compute Module 4 gateway – iModGATE-AI – specially designed for failure monitoring and predictive maintenance of IoT installations, which also embeds a Google Coral Edge TPU AI module to accelerate computer vision. iModGATE-AI gateway specifications: SoM – Raspberry Pi Compute Module 4 with up to 32GB eMMC AI accelerator – Google Coral Edge TPU AI module Video Output – HDMI port Connectivity – Gigabit Ethernet USB – USB 2.0 port Sensors – 9-axis motion tracking module with 3-axis gyroscope with Programmable FSR, 3-axis accelerometer with Programmable FSR, 3-axis compass (magnetometer) Expansion 2x 16-pin block terminal Advanced […]

Raspberry Pi case embeds 192 programmable LEDs, speaker, microphone, and sensors (Crowdfunding)

Most Raspberry Pi enclosures are designed to protect your board from dust, provide easy access to ports, and in other cases, ease the installation of hard drives or SSDs. But Abstract Foundry’s LumiCube does much more, and just calling it a case or enclosure is an understatement, as while it does house a Raspberry Pi, it also comes with 192 programmable LEDs placed over 3 panels, a speaker, a microphone, as well as several optional motion & environmental sensors, and a small 2-inch LCD display. LumiCube specifications: Acrylic base 3x RGB LED panels with 64 programmable LEDs each Audio – 2W speaker and microphone Display (optional) – 2-inch 320×240 IPS screen for system parameters or other info (e.g. sensor data) or images. Note that it can now show the Raspberry Pi desktop Sensors (optional) – Light & gesture sensor, BME280 temperature, humidity and pressure sensor, BNO055 IMU (accelerator and tilt […]

Crowbits Master Kit Review – Part 1: A first look at the ESP32 based education kit

Crowbits STEM education kits comprised of magnetic modules launched on Kickstarter a couple of weeks ago. There are five kits increasing in difficulty with the Hello Kit just requiring the student to connect modules to get started, i.e. no programming required, to the Crowbits Master Kit based on a battery-powered ESP32 module suitable to create your own phone, portable game console, radar tower, etc… Elecrow sent me the latter for evaluation, and in the first part of the review, I’ll unbox the kit, see how modules mechanically fit together, and have a quick look at the user manual, before trying one or two projects from the manual in the second part. This is the second STEAM product from Elecrow that I review, as I reviewed CrowPi2 Raspberry Pi 4 laptop last year. Let’s open the package. We have a total of six modules with two joysticks, an ESP32 module with […]

Arduino MKR IoT Carrier embeds display, sensors, and I/Os for IoT projects

Arduino Oplà IoT Kit was launched last fall as the first open programmable IoT platform from the company. The kit included everything you need to create your own IoT devices with MKR IoT carrier with a 1.3-inch OLED color display, environmental sensors, capacitive touch buttons, Arduino MKR WiFi 1010 board, external PIR motion and moisture sensors, a circular plastic enclosure, and various cables. But the community soon wanted to only buy the carrier board without having to purchase the whole kit, so Arduino has just started to sell MKR IoT Carrier board as a standalone product. Arduino MKR IoT Carrier features & specifications: Compatible with Arduino MKR family boards with WiFi, LoRa, NB-IoT, or 3G cellular connectivity Storage – MicroSD card holder Display – Round 1.3-inch OLED display I/Os 2x 24V relays 3x Grove connectors include two analog and one digital (I2C) Sensors – Temperature, humidity, pressure, RGBC light, gesture […]
