Superconductivity Exhibited by New Material with Room Temp Hopes

Superconductivity Exhibited by New Material with Room Temp Hopes

PORTLAND, Ore. — Today we have superconductors levitating trains for high-speed transportation, superconductors wired as ultra-sensitive sensors for MRI (magnetic resonance imaging) and superconducting coils powering ultra-strong electromagnets for beam steering in particle accelerators. However, if a room-temperature version of these superconductors — which today have to be ultra-cooled — could be found, then they […]

Running NodeMCU on a battery

Running NodeMCU on a battery: ESP8266 low power consumption revisited Over the last year I have standardised on the ESP8266 for all my small IoT projects. Its low price, ease of use (now that the Arduino IDE is available), tiny size and built in Wi-Fi makes it a compelling option. Using Wi-Fi is a convenient way to link

Water Softener LED Display

Many homes in the United States have water that contains higher concentrations of dissolved minerals, which is called hard water. Although there is nothing toxic about hard water, it is less desirable for cleaning, it leaves mineral deposits, and it can shorten the lifetime or efficiency of equipment such as water heaters. A water softener

GET A CONSTANT 5V OUTPUT BY SWITCHING BETWEEN A 5V INPUT AND A SINGLE CELL LI RECHARGEABLE CELL

GET A CONSTANT +5V OUTPUT BY SWITCHING BETWEEN A +5V INPUT AND A SINGLE-CELL LI+ RECHARGEABLE CELL

Abstract: Design provides a simple method for maintaining an uninterrupted +5V even while switching between the external +5V supply and a rechargeable single-cell Li+ battery. Some portable applications need to be powered up from an external +5V wall adapter supply and still require a +5V system voltage when in battery-backup mode. This design provides a

IKEA Samtid mood light upgrade

IKEA Samtid mood-light upgrade

This upgrade is based on the loved-by-everybody WS2812B intelligent RGB LED and works just fine with Adafruit’s NeoPixel library. The concept is – once again – rather simple. Whack a lot of WS2812B RGB LEDs onto a small board, add an ubiquitous ‘Arduino core’ and make sure everything fits nicely and works. Well, it worked.

Chip adds precision altitude sensing to mobiles

Chip adds precision altitude sensing to mobiles

Brief Description The ZSSC3016 is a sensor signal conditioner (SSC) integrated circuit for high-accuracy amplification and analog-to-digital conversion of a differential input signal. Designed for high resolution altimeter module applications, the ZSSC3016 can perform offset, span, and 1st and 2nd order temperature compensation of the measured signal. Developed for correction of resistive bridge sensors, it

Posting a Tweet with the ESP8266

In this project you’re going to post a Tweet with an ESP8266. The goal of this project is to show the endless possibilities that this $4 WiFi module offers when integrates with a free platform that I’m about to show you. In order to accomplish this task you have to sign up for one free service called IFTTT which stands
