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 ...

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 your newly created IoT device into your existing IT infrastructure – including cloud ser ...

It´s hard to resist to R&S HMO1002 oscilloscope for 610 Euro

Professionals, school laboratories and amateurs can now gain this new, extra affordable digital MSO oscilloscope in a limited offer. Probably you may have noticed, that company Hameg became a member of Rohde&Schwarz group and new oscilloscopes already carry only an R&S logo. However the name of series HMO remains, which represents for several years products with an excellent price/ performance ratio ...

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 is a household appliance that commonly exchanges salt for some of th ...

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 simple method of switching between the external +5V s ...

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. This post gives a short overview of V0.27.a of this project. As this is NOT a step-by ...

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 for “If This Then That”.IFTTT is a platform that gives you creative control over dozens o ...
