Omron HeartGuide Wearable Blood Pressure Monitor is Finally Available

Way back at CES 2016, Omron showcased Project Zero BP6000 wearable blood pressure monitor that was meant to be an FDA approved blood pressure monitor fitting into a watch form factor and starting to sell for $200 at the end of 2016. But the device was not particularly eye-pleasing and FDA approval is really hard, so they unveiled the thinner and prettier Project Zero 2.0 model the next year at CES 2017 with the goal of releasing the device sometimes in 2018 for $300. The good is that the product – now called HeartGuide – will up for pre-order, and slated to ship in January 2019. Sadly, the cost has gone way up since it now sells for $499, and will only ship to a US address. HeartGuide (BP8000-M) wearable blood pressure monitor technical specifications: Display – Transflective memory-in-pixel LCD Memory – Blood pressure measurement up to 100 times, activity […]

BLE Micro is a Tiny, Coin-Cell Powered Bluetooth 4.0 Development Board

DFRobot Bluno is a Bluetooth 4.0 LE development board following Arduino UNO form factor, and powered by TI CC2540 chipset. The board sells for $24.90 on their online store, and the company provides firmware and mobile app source code, but if you ever wanted a similar solution in a much smaller form factor, and powered by a coin cell battery, the company has now launched BLE Micro board. BLE Micro board specifications: Bluetooth Chip – Texas Instruments CC2540 8051 MCU with USB, Bluetooth 4.0 LE connectivity Wireless Connectivity Frequency: 2.4GHz Transfer rate: ≤1Mbps Modulation: GFSK, Bluetooth low power, V4.0 Sensitivity: -93dB Transmission distance – 30m in free space USB – 1x micro USB port Expansion – 21 through holes with reset, power signals, UART, and GPIOs. Input Voltage: +3.3 DC Power Consumption – Working: 10.6mA average, ready mode:8.7mA Temperature Range – -10 ℃ ~ +65 ℃ Dimensions – 49mm x […]

Kohler Novita “Therapy Bidet” Bluetooth LE Enabled Toilet Seat Works with Android & iOS Smartphones

If you’ve ever been to Japan, and to a lesser extend in Korea, you’ll probably have used one those toilet seat that sprays water, and ends with a gentle drying once you’re done with business. That’s all good, but you’d still need to press the buttons to activate it, and who knows what kind of germs may be on those buttons. But with Nordic Semi nRF52832 powered Kohler Novita “Therapy Bidet” (BD-TE80M) you don’t need to worry about third party germs, since it can be controlled over Bluetooth LE with your very own smartphone contaminated with your very own germs. The toilet seat bidet supports three different spray modes (active, silky, and mist) aka “water experiences”, as well as dual dry air blower combined with far infrared for “better skin care” and improved blood circulation. An auto-customization mode is available for ladies during the thing that normally happens every moon […]

$50 Fish32 Seed “Education” ESP32 Board Comes with Plenty of I/Os, Sensors, and Connectivity Options

Sometimes I feel the word “Education” is sometimes thrown around for marketing purpose, and AnalogLamb Fish32 Seed board for “ESP32 Community Education Board” feels that way to me as so far, I could not see any tutorials or other teaching/ learning resources for the board. Having said that I can see why it could be potentially used for education: the sheer number of features, sensors, and connectivity options should allow students to learn to program my different components around ESP32. It’s just at this stage it may not be such an easy platform to learn on. Fish32 Seed board specifications: Supported ESP32 Modules – ESP32-WROVER, ALB32-WROVER, ESP32-WROOM-32 Connectivity 802.11 b/g/n WiFi and Bluetooth 4.2 via ESP32 10/100M Ethernet (RJ45) via WIZnet W5500 chip with support for up to 8 independent sockets LoRa via SX1278 chip (433 MHz) Sensors NXP MPU-9250 with 3-axis MEMS gyroscope, 3-axis MEMS accelerometer, 3-axis MEMS magnetometer […]

Espruino Pixl.js is a Bluetooth LE Display Programmable with JavaScript, Compatible with Arduino Shields

Espruino is an open source firmware that allows you to control micro-controllers board with JavaScript, and used in hardware such as Wio LTE GPS tracker, some STM32 Cellular IoT Discovery Kits, and other platforms. I have actually tried Espruino and JavaScript programming in an ESP32 board myself, and it worked reasonably well. But Espruino developers also provide hardware platforms for Espruino, which – as one should expect – are normally better supported than other third-party board. One of their latest platforms is Espruino Pixl.js a Bluetooth smart display powered by Nordic Semi nRF52832 WiSoC. Espruino Pixl.js specifications: WiSoC – Nordic Semi nRF52832 Arm Cortex-M4 @ 64MHz with 64kB RAM, 512kB Flash, Bluetooth Low Energy connectivity (via a Raytac Corportation module) Display – 54mm diagonal, 128 x 64 sunlight readable monochrome display with white backlight Connectivity – Bluetooth LE and NFC tag I/Os 20x GPIO in Arduino footprint with PWM, SPI, […]

KidBright32 Board is Thailand’s BBC Micro:Bit Equivalent

BBC Micro:Bit board was first announced in July 2015. Designed for STEM education, the board was then offered to UK schools in March 2016, and a few months later UK store would start selling it worldwide. It’s now available pretty much anywhere, and you can likely find it in a local store or online. The Thai government must have seen this, and thought to themselves “If the British can do it, we can do it too!”, as the National Electronics and Computer Technology Center (NECTEC) part of Thailand’s Ministry of Science and Technology designed KidBright32 board and courses to teach STEM to Thai students. The board is based on Espressif Systems ESP32-WROOM-32 WiFI and Bluetooth module, and comes with large holes for power (5V/GND) and 6 digital inputs/outputs, smaller through holes for I2C and more I/Os, as well as an I2C header. We’ll also find some LEDs, two dot matrix […]

ESP32-SOLO-1 is a Single Core ESP32 WiFi and Bluetooth Module

Espressif ESP32 is popular dual core processor with built-in WiFi and Bluetooth connectivity, except as we’ve seen last year, the company also developed a single core version with ESP32-S0WD chip, whose price is only slightly more expensive than ESP8266. But so far, I had not seen many hardware platforms announced with the single core version, with the exception of Particle Argon board. But I believe we should soon see more ESP32-S0WD boards brought to market, since Espressif Systems has now announced ESP32-SOLO-1 single core module. ESP32-SOLO-1 wireless module specifications: SoC – Espressif ESP32-S0WD single core Tensilica Xtensa LX6 processor @ up to 160 MHz with 448 KB ROM, 520KB on-chip SRAM, and 16KB SRAM in RTC Storage – 4MB SPI flash Connectivity 2.4 GHz 802.11 b/g/n WiFi up to 150 Mbps Bluetooth 4.2 LE + EDR I/Os – SD card, UART, SPI, SDIO, I2C, LED PWM, motor PWM, I2S, IR, […]
