Maxim Announces Wearable ECG and Heart Monitor Development Kits

Maxim ECG Heart Monitor Development Kits

Maxim Integrated has recently announced two wearable development kits for fitness / health tracking: MAX-HEALTH-BAND watch for vital signs MAX-ECG-MONITOR with a chest strap for clinical-grade electrocardiograph (ECG) and heart rate. MAX-HEALTH-BAND Development Kit The MAX-HEALTH-BAND wrist-worn heart-rate and activity monitor features the company’s MAX86140 optical pulse-oximeter/heart-rate sensor, MAX20303 wearable power-management solution, and Maxim’s motion-compensated algorithms. The watch sends raw PPG and accelerometer data via Bluetooth to a smartphone app, and also monitors steps, activity, heart rate and interbeat intervals for heart-rate variability measurements. Battery life is around 7 days on a single charge. The kit also includes a USB charging cable, and instructions to download the Android-based application. The evaluation platform can be used for the development of fitness and wellness trackers, health monitoring trackers, or as a experimentation platform for new use cases and algorithms. In addition to raw PPG and accelerometer data, the MAX-HEALTH-BAND monitors steps, activity, […]

LoStik USB Dongle Adds LoRa Connectivity to any Computer or Linux Board (Crowdfunding)

We’ve covered plenty of hardware with LoRa radio from gateways, to Arduino shields, tracker boards, and mini PCIe cards, but after reading an article on Time4EE this morning, I realized we never wrote about any LoRa USB stick. LoStik – previoulsy LoRa Stick – is an open source hardware USB dongle based on Microchip RN2903 / RN2483 LoRa module, and offered on CrowdSupply for $39. LoStik specifications: USB – USB 2.0 port LoRa Connectivity Microchip RN2903 – 915 MHz for US, Canada, South America and Australia Microchip RN2483 – 868 Mhz for Europe Receiver Sensitivity – down to -146 dBm TX Power – adjustable up to +18.5 dBm Range – up to 15 km coverage in suburban and up to 5 km coverage in urban areas Misc – 2x user LEDs Power Consumption – 140 ma typical TX, 20 ma idle (with power LED) Dimensions – 80 mm x 25 […]

SD Express Adds PCIe and NVMe Interfaces to SD Cards for up to 985 MB/s Transfer Rates

SD cards are known for the convenience, portability, and relatively cheap prices, but not so much for their performance which can be pretty poor especially for the cheaper and lower capacity models, and when fast random I/O is needed. The SD Association have been working on helping customer buy performant cards for their needs with – for instance – the app performance class introduced in SD 5.1 specification, which defines minimum random read and write speeds in Class A1 and Class A2 micro SD cards. However, the association has gone a step further with SD Express found in SD specification 7.0 that adds PCIe and NVMe interfaces to the legacy SD card interface. SD Express will enable theoretical data transfer rate up to 985 MB/s via PCIe 3.0, as well as advanced memory access mechanisms such as Bus Mastering, Multi Queue (without locking mechanism) and Host Memory Buffer thanks to […]

Tail it is a Family of WiFi & Cellular GPS Trackers for Things, Pets, and Bicycles (Crowdfunding)

We’ve previously written about Ping, a tiny Cellular GPS tracker that promised to last 3 months on a charge. The raising money part of the crowdfunding campaign itself was successfully with over one million dollars raised, but as with many such campaigns there have been delays, and some people still have to receive theirs, not to mention people complaining about poor battery life and other issues. But there seems to be another option now with Tail It Technologies now offering four different “Tail it” cellular GPS trackers (with WiFi too) for things, pets, and even one designed specifically for bicycles. The company has already sold their devices to thousands of customers in Norway, so they should be working, and on-time delivery should hopefully not be an issue. All four GPS trackers come with 2G, 3G, 4G, and WiFi connectivity, a 5-meter accuracy, and share the same electronics and firmware. Here’s […]

NoCAN IoT Platform Leverages Raspberry Pi & Arduino for CAN Bus Projects (Crowdfunding)

Many IoT projects rely on wireless connectivity through WiFi or Bluetooth, but in some cases it may be more reliable and convenient to use wired connectivity. The CAN Bus is a little like a low bandwidth Ethernet PoE solution for IoT, as it allows to transfer data over a serial connection while provided power at the same time, and can be daisy chain to support multiple boards. Omzlo’s NoCAN IoT platform provides a CAN bus solution leveraging Raspberry Pi 3 board through their PiMaster HAT acting as a CAN bus gateway, and Arduino compatible CANZERO boards to which you can connect sensors and actuators. Omzlo PiMaster HAT specifications: MCU – STMicro STM32F042 Cortex-M0 32bit ARM MCU – 48Mhz. Networking – 125000 bps CAN bus up to 300 meters range GPIO – Communicates with Raspberry Pi through SPI + GPIOs Security – Smart power switch with over-current protection. Power Supply – […]

Firewalla is a Tiny Firewall Appliance Based on NanoPi NEO Board

FriendlyELEC Nanopi NEO and NEO2 boards are really cool and inexpensive little Arm Linux boards suitable for all sort of headless application. I’ve reviewed one with their NAS Kit, and run one around the clock as a Domoticz/MQTT server. So it should come as no surprise that some people want to leverage the hardware in their own products, and Firewalla most likely relies on a NanoPi NEO board for their cute firewall/parental control/VPN appliance.Firewalla specifications: SoC – Unnamed quad-core Arm processor @ 1.0 GHz System Memory – 512 Megabyte DDR RAM Storage – 16GB MicroSD Storage Connectivity – 100 Mbit Software Packet Processing Power – 5V via micro USB port Dimensions – 2.8 cm thick The device ships with a flat Ethernet cable, a USB power cable and US type power adapter, and a one year limited manufacturer warranty. The company does not actually mention NanoPi NEO board anywhere, but the specifications […]

YouTube Streams 1 & 2 Update, Plus Quick Fix for Uneven X Gantry

Hey Karl here with an update on the YouTube Live streams from last week. Live Streams Update The 1st stream went about as well as I expected….Not very well. I was really nervous and I broke the live link that was posted on here at the last minute. My whole reasoning for the Livestream was to show the processes in real time and not do too much footwork ahead of time. On the first one I was planning on migrating from Marlin 1.1.6 to Marlin 1.1.8 but I had already done lol… So I ended up migrating to the bugfix branch which presented additional challenges. Overall it was successful and I hope I conveyed the process. I was able to get it to print but I ended up going back to 1.1.8 due to some error in the bugfix branch that caused weird jittery movement. I will in the future […]
