tinyPulsePPG – ATTiny85 Pulse oximeter with photoplethysmogram

Posted on by mixos

tinyPulsePPG, an ATTiny85 Pulse Oximeter with Photoplethysmogram (PPG) display by Jeff Magee:

This project implemented on an ATTiny85 displays a moving Photoplethysmogram together with pulse rate and estimates of SpO2 – blood oxygen percentage. It uses an SSD1306 128×32 OLED display and a Max30102 sensor. It is emphasized that this should not be used for medical purposes. The computation of SpO2 is very approximate and not calibrated in any way. The project is an exercise in software and hardware parsimony.

Peakago 7-inch Windows 10 Fanless Mini-Laptop Launched for $269 and Up

Posted on by mixos

Peakago Computer has started an IndieGoGo campaign for its 7″ fanless laptop and mini-PC the Peakago. The campaign has raised 831% of the original target funding on its first day.

The Peakago is not a new idea, as there have been a number of 7″ to 9″  display laptops that offer Windows operating systems. The advent of the pocket sized laptop has inspired a number of different versions of similar types and operating systems. The Pretech 700Mi Mini is one of those iterations that was reported on here and is a look-alike to the Peakago. In fact, Peakago and the Pretech are from the same tooling company.

The campaign does say the display has a 178° viewing area, but this unit is very portable and could easily be used in a densely populated locale, so maybe such a wide viewing angle might inspire the manufacturer to develop a privacy screen.  It must be said that such a wide viewing angle is also a real boon to such a small display.

Introduction Video

Pricing for crowdfunding early bird :

  • 4GB RAM/64GB storage for $269
  • 8GB RAM/128GB storage for $339
  • 8GB RAM/128GB  storage+ 4G LTE for $399

Some Good, Some Missing, Features

The Peakago has a 360º hinge that allows the mini-laptop to become a tablet. There is an inexpensive webcam, which is somewhat new to the 7″ mini-laptop realm. The keyboard isn’t backlit and there is no fingerprint reader, which is becoming a standard issue now. No support for an active stylus.

There is fast charging with a USB Type-C connector, not a power cord. There is a micro HDMI port for display expansion. Although it seemed a little bit ambitious to run a screen of the size in the promotional.

AmbiMate MS4 Multi-Sensor Module cuts time to market for smart building systems

Posted on by mixos

TE Connectivity (TE), a world leader in connectivity and sensors, has launched the AmbiMate MS4 multi-sensor module that integrates the most popular set of sensors needed for most smart building solutions. Because engineers can use the pre-engineered module instead of up to seven individual sensors, it reduces the time required to research, source and integrate multiple sensors. This reduces time to market and frees up resources to work on other aspects of smart building system designs.

Different AmbiMate module options are available to meet different specifications. A basic version has the four core sensors of passive infrared, ambient light, temperature and humidity to enable control of heating and lighting. However, customers can choose to add a microphone and / or equivalent carbon dioxide and volatile organic compound (VOC) sensors for features such as voice activation and air quality management.

Jonathan Catchpole, System Architect at TE Connectivity’s Industrial business said:

“Engineers face the challenges of looming deadlines, unforeseen technical obstacles and high expectations. We designed the AmbiMate sensor module as the best possible set of sensors for intelligent buildings so that Engineers can focus their efforts on the aspects of their project that set their product apart from the competition, whether that is cloud integration, software or meeting the WELL Building Standard.”

The sensor module is available to buy as a standalone printed circuit board assembly (PCBA) in bulk and also as a developer kit. The developer kit includes multiple attachment options to give developers flexibility in the mechanical fit and connection inside their product housing. Electronics developers can plug an AmbiMate module into a host controller like a Raspberry Pi or Arduino device and start collecting data within 30 minutes with support of code that is freely available on TE.com. The module is compatible with the I2C communication protocol.

AmbiMate MS4 multi-sensor module

The AmbiMate sensor module is available from electronics distributors for as little as $19.50 per unit for the core set of sensors.

Features

  • Four Core Sense Capability
    • Motion (PIR)
    • Light
    • Temperature
    • Humidity
  • Optional Sense Capability
    • VOC
    • CO2
    • Sound (Microphone)
  • Free up design resources and accelerate time to market
  • Simplicity of popular I2C communication protocol
  • Space saving compact design

esp32MX-E, The New Chip on the Block

Posted on by Tope Oluyemi

There are a host of boards based around the ESP32, and also its follow up, the ESP8266. It’s noteworthy to witness how they have evolved from the simple breakout boards they were when the chip was released back in 2015 to something a lot more major. The latest of these boards is the esp32MX-E from Modtronix Engineering, which will be raising soon on Crowd Supply.

Measuring at 64.4 × 42 mm (2.54 × 1.65 inch), the board is designed based on an off the shelf ESP-WROOM-32 module. One interesting feature is its independent methods of powering the board; a USB-C connector, a 2.1 mm barrel connector, or via broken-out +V and GND pins, the board can be powered with a 4.5 to 16 V supply. The on-board USB connector also enables a serial console, and allows you to program the board. The board offers both Wi-Fi, and Bluetooth, enabled by the ESP32, and also an Ethernet jack. The board also features a Micro SD card slot, along with a user addressable LED and button. The ESP32 board is built around a dual-core 32-bit Tensilica’s Xtensa LX6 micro-processor which operates at either 160 or 240 MHz, equipped with 4MB of SPI Flash, and 520KB of SRAM.

The board also has a user-programmable STMicroelectronics STM32F030F4 micro-controller. The micro-controller is a 32-bit Arm Cortex-M0 core operating at 48 MHz, with 256 KB of Flash and 32 KB of SRAM. The I²C I/O secondary processor expander handles the pins on the two expansion headers; the first has 2×7 pins, and the other has 2×10 pins with programmable pull-up and pull-down resistors on most inputs. We should note that not all of the pins are available when the SD card slot is in use.

The board will be released in two versions, but with different operating range. While both will have the same configurations, one will have an operating range of 0° C to 85° C, while the second, an ‘industrial’ version, will operate at temperatures down to -40° C. The board is aimed squarely towards the Internet of Things (IoT) and industry, and will be housed in anonymous black or grey boxes with numbers written in sharpie on the outside for easy identification from other boxes.
