RESEARCHERS DEVELOPED HYBRID 3D PRINTING METHOD TO MAKE FLEXIBLE WEARABLE DEVICES

Wearable electronic devices that intend to track and measure the body’s movements must be soft enough to flex and stretch to accommodate every body-movement. But, integrating rigid electronics on skin-like flexible materials has proven to be challenging. Clearly, Such components cannot stretch like soft materials can, and this mismatch frequently causes wearable devices to fail. Recently scientists solved t ...

Students invent automatic six seconds whiteboard cleaner

Two students are behind an idea that could change how a classroom operates. Stephen Kibe and Evans Simiyu, both fifth year Mechanical and Manufacturing Engineering students, are behind an innovation that will make cleaning the board easier. “According to research done, a lot of time is spent on cleaning the whiteboard in a classroom. This cleaning goes beyond time wastage to interfering with ...

Color sensor achieves high dynamic range with auto exposure

The Design Idea in Figure 1 is a color detector capable of generating an RGB triplet over a high dynamic range, a useful attribute for machine vision applications. The circuit implements auto-exposure control to achieve this. Thus, RGB values for a subject are invariant over a range of light intensity. The three common-cathode RGB photodiodes (U1) are reverse‑biased and pre-charged to VR (typically 0.5V) th ...

Magic Mote MSP430G2553 wireless sensor node with NRF24L01+ module

This is my first time designing a PCB for MSP430. I really like the NRF24L01+ booster pack but I would like something smaller to use for remote temperature sensors. With that in mind I've designed a 24.5 x 50 mm PCB (2 on a 5x5 cm prototype) featuring MSP430G2553 and an adapter for a 8-pin NRF24L01+ module using essentially the same pinout, with the intention of using the Spirilis library. There's a jack so ...

SPRINTIR6S, WORLD’S FASTEST NDIR CO2 SENSOR

is a designer and manufacturer of low power, high speed Non-Dispersive Infrared (NDIR) carbon dioxide gas sensors. Recently, it has claimed a new speed record for its SprintIR6S NDIR CO2 sensor. The new sensor comes with response rates that had never been reached before by any other NDIR CO2 sensors. It can take up to 20 readings per second, and has a six-times faster response rate than the current SprintIR ...

Creating a Smart Water Sensor with the ESP32 Thing

Over the Christmas break, my parents were out of town to celebrate the holidays. When they came back, they saw something every homeowner fears – a flooded basement. In a basement, there are pipes that collect water from around the foundation and bring it into the sump pit, which pumps it out away from the house. When the sump pump fails, water has no way to leave the basement and it floods. I recently bough ...
