Wearable SweatSenser Picks up Stress, Infection Levels by Sampling Tiny Amounts of Your Sweat
Capable of working even if you don’t think you’re sweating, the SweatSenser is suitable for long-term monitoring of stress levels and more.
A novel wearable sweat sensor, developed by researchers at the University of Texas at Dallas and in the process of being commercialized by EnLiSense, could provide insight into the health and stress levels of wearers — even if it can only sample a tiny amount of sweat.
DIY WS2812 Analog style Arduino Ring Clock
This time I will show you how to build a nice-looking ring clock. The clock uses a WS2812 ring containing 60 Leds,(4 Quarter circle neopixels x 15 Leds) and it is ideal for this purpose. This is a analog style digital clock with multiple display states, a 24-hour alarm, a count down alarm, multiple alarm display states and a demo mode. Hours, minutes and seconds are represented by a different color of the corresponding LED.
Highly Unofficial “Raspberry Pi 3B Mini,” Customized for TPCast, Appears for Sale
Cut-down single-board computer packs the same power as a Raspberry Pi 3, but in a more compact footprint.
An unusual customized Raspberry Pi variant, designed for use in video streaming applications, has surfaced for sale — and it’s been dubbed, extremely unofficially, the “Raspberry Pi 3B Mini.”
Bendable Color Epaper Display has Touch Input too
The Interactive Media Lab at Dresden Technical University has been busy working on ideas for user interfaces with wearable electronics, and presents a nice project, that any of us could reproduce, to create your very own wearable colour epaper display device. They even figured out a tidy way to add touch input as well. By sticking three linear resistive touch strips, which are effectively touch potentiometers, to a backing sheet and placing the latter directly behind the Plastic Logic Legio 2.1″ flexible electrophoretic display (EPD), a rudimentary touch interface was created. It does look like it needs a fair bit of force to be applied to the display, to be detectable at the touch strips, but it should be able to take it.
How to Burn bootloader on new atmega328 using Arduino UNO
Here in this video i will show you How to burn bootloader to the new Atmega328 using Arduino Uno to be ready for easy programing for new projects or to replace the original Atmega328 chip on the Arduino Uno
PicoLight – Minimalist Light for Product Shots
PicoLight is a minimalist adjustable light for low-light photography, based on the Raspberry Pi Pico.
One of the activities I really enjoy while working on a new project is documenting it. I love getting creative while taking pictures of the process and of the final products. A thing that has been really handy in this process is an adjustable studio light, which I use to add a bit of colour to the background (that’s why most of the pictures in these tutorials are purple hehe).
PicoLight is a smaller version of a classic studio light that is useful for playing with colours in low-light shots or for coloured shadows photography.
Dave Plummer’s M5StickC Audio Spectrum Analyzer Runs at a Smooth 30 Frames Per Second
Simple yet colorful project makes full use of the ESP32’s processing power, that bright display, and the on-board microphone.
Former Microsoft programmer and father of the Windows Task Manager Dave Plummer has been looking into embedded projects of late, turning the M5StickC into a colorful live-view audio spectrum analyzer — running at 30 frames a second.
