A Closer Look at Ingenu RPMA Alternative to LoRa or Sigfox LPWAN Standards & RPMA Development Kit

I’ve recently started to write a bit more about long range LPWAN standards for IoT applications, especially LoRa and Sigfox, as commercial networks are being launched, and relatively low cost hardware platforms are being introduced to the market. There are also other highly expected standards such as Weightless and LTE Cat M that will bring more competition to the market. Ingenu RPMA (Random Phase Multiple Access) is another available standard that’s been in deployment for a while, and based on an earlier comparison of long range LPWAN standards, it comes with long range, supports up to 384,000 nodes per “sector”, operates in the unlicensed 2.4 GHz ISM band, and offers high combined uplink and downlink bandwidth than competitors. Ingenu recently contacted me and provided some more details and information about their technology and development kit. One of the documents includes an “independent analysis completed by ABI Research, Inc.” comparing features […]

Meet Body Heat Powered MATRIX PowerWatch, The Activity Tracker You Never Need to Charge (Crowdfunding)

There are currently several issues with wearables that makes it sub-optimal devices, from displays that can’t be always-on, to unreliable sensors, and in my experience pretty poor reliability, as I’ve managed to go through 4 fitness trackers / smartwatches in a year. Another issue is that contrary to typical watches lasting 10 years with a coin cell battery, most wearables require to be charge every few days, weeks, with the very best devices being chargers every few months. MATRIX PowerWatch promises to solve latter, as you will never need to ever charge it since it charges itself by harvesting energy using your body heat. The company promotes it as a smartwatch, but it’s closer to an activity tracker, since you can’t keep the Bluetooth LE connection all the time in order to receive notifications to your smartphone. It’s basically used to show time, track your activity and sleep patterns, and […]

RabbitMax Flex IoT Board for Raspberry Pi Supporting up to Five I2C Sensors Launched on Indiegogo for 20 Euros and Up

RabbitMax Flex is an add-on board, compatible with HAT specifications, for Raspberry Pi 2 /3 boards and other Raspberry Pi models with a 40-pin GPIO header. It includes headers for up to 5 I2C sensors, as well as an RGB LED, a buzzer, a relay, a button, infrared receiver and transmitter, and an optional LCD display, and as we’ve seen in my RabbitMax Flex getting started guide, a nice way to learning about hardware programming using either C or Python, or to used in home automation or IoT projects. The project has just been launched on Indiegogo. RabbitMax Flex specifications: Relay – Songle SRD-05VDC-SL-C supporting 125V/250VAC up to 10A, 30VDC up to 10A Storage – EEPROM with some system information for identification IR – IR LED, IR receiver Misc – Buzzer, Button, RGB LED Expansion Header for LCD character display + potentiometer for backlight adjustment 5x 4-pin headers for I2C […]

Getting Started with RabbitMax Flex IoT and Automation Hat for Raspberry Pi

At the beginning of the month I showed how to assemble RabbitMax Flex, a Raspberry Pi HAT compliant add-on board for Raspberry Pi boards with 40-pin header, that targets IoT and home automation project with its relay, IR transmitter and receiver, I2C headers for sensors, buzzer, RGB LED, and more. Since I’ve already described the hardware, I’ve spend some time this week-end following the user’s guide to play around with the board using a Raspberry Pi 2 board, and try various features. The user’s manual explains that you need the latest version of Raspbian, but I’d not played with my Raspberry Pi 2 board for a while, so the kernel and firmware were quite old:

uname -a
Linux raspberrypi 4.1.7-v7+ #817 SMP PREEMPT Sat Sep 19 15:32:00 BST 2015 armv7l GNU/Linux
pi@raspberrypi ~ $ /opt/vc/bin/vcgencmd version

version c156d00b148c30a3ba28ec376c9c01e95a77d6d5 (clean) (release)

So the first thing I had to do was to upgrade Raspbian. There are basically two options to upgrade, either downloading and dumping the latest Raspbian firmware image to your micro SD card, and […]

Exilong RF & WiFi Irrigation System Automatically Takes Care of Your Garden Watering (Crowdfunding)

I find it fun to spend time watering the flowers and grass in my garden, but if you’d rather do it automatically then Tevatronic Exilong might be for you as the irrigation system controls up to 4 valves, triggers watering based on RF water sensing sensors via a gateway connected to the cloud through your wireless router. The kit gateway takes care of RF communication with sensors, WiFi connectivity to the cloud server, and turn on and off up to four 24V DC water valve part of your existing installation. It can be configured by iOS or Android mobile app, or your web browser. The other part of the kit are the water pressure sensors that you need to insert into the soil of your garden in order to monitor trees, bushes, and/or flowers. The sensors are using RF (433/915 MHz) communication, send data back to the gateway every minute, […]
