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.
After replacing the internals of an original 4th gen iPod with a Raspberry Pi Zero W, it now supports modern features and a bigger battery.
The original iPod was what many consider to be the product that launched Apple into the realm of pocketable consumer technology and acted as a precursor to the now ubiquitous iPhone lineup. In recent times, the nearly two decades-old technology within the iPod is very outdated, but rather than throwing his old one out, one user who goes by production on Hackaday.io decided to upgrade it with some new internals while still being able to control everything with the original buttons and capacitive front wheel.
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.
How about getting rid of that broken volume knob on your stereo and replacing it with some buttons, LEDs and Bluetooth?
In this Raspberry Pi boot from USB guide, we will be showing you how it is possible to boot your chosen operating system from a USB storage device instead of the standard SD card.
We will walk you through the steps required to activate the USB boot mode in the one-time programmable (OTP) memory. You will need a newer Raspberry Pi to complete this tutorial correctly (see below).
We’re delighted to see the progress on [Foaly]’s 3D-printed Cortex 2 rocket, and the latest build log is full of beautiful pictures and design details. Not only is this rocket jam-packed with an efficiency of electronics and smart design, but it almost seems out to single-handedly prove that 3D-printing is far from the novelty some think it is.
There is so much going on in the Cortex 2 that it simply wouldn’t be possible to do everything it does without the ability to make one’s own parts exactly to specification. In fact, there is so much going on that cable management is its own challenge.
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.”
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.
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
This robot inspects objects from different angles to classify them with a high degree of accuracy in real world scenarios.
Object recognition is a critical piece of many machine learning applications. Whether the goal is to create an autonomous car, a warehouse robot, or a package delivery drone, in each case, the devices must be capable of recognizing the objects that are around them. There are many proven models that classify a wide range of objects with a high degree of accuracy; however, these models do not always perform as expected under real world scenarios.
