“We are back with another issue of HispaBrick Magazine: number 31. In this issue you can see how AFOLs enjoy events in different countries like Japan, (Japan BrickFest), Chile (Brickfest Chile) or Denmark (LEGO® World Copenhagen). We visit LEGOLAND Japan …

How to Build and Flash ESPurna Open Source Firmware to Sonoff POW Wireless Switch

“ITEAD Studio Sonoff family is comprised of various inexpensive ESP8266 WiFi power switch, and the company sent me two of their latest CE certified models with Sonoff TH16 + external temperature & humidity probe, and Sonoff POW to measure power consumption. I …

How to Make a Wristband Pedometer

“I am fond of walking and running in the district I live in. I enjoy the time to be alone because some awesome ideas always come to me at this time. Recently I bought a 6-Axis Inertial Motion Sensor from …

How to melt gold at room temperature

“When the tension rises, unexpected things can happen – not least when it comes to gold atoms. Researchers from, among others, Chalmers University of Technology, have now managed, for the first time, to make the surface of a gold object melt …

Infinity Clock - Arduino - WS2813 and DS3231

“Infinity Clock - Arduino - WS2813 and DS3231I wanted to build a clock, and liked the idea of trying my hand at making an infinity clock with an Arduino. I wanted it to build it out of common items, and write the …

InSight Is Catching Rays on Mars

“NASA’s InSight has sent signals to Earth indicating that its solar panels are open and collecting sunlight on the Martian surface. NASA’s Mars Odyssey orbiter relayed the signals, which were received on Earth at about 5:30 p …

LEAP: Little Electronic and Arduino Projects

“LEAP is my collection of electronics projects, many involving an Arduino in one way or another. Some are full builds like The FretBoard, while many are trivial breadboard kata, intended to test or explore a single idea. Many are variations …

Living electrodes with bacteria and organic electronics

“Researchers at the Laboratory of Organic Electronics, Campus Norrköping, have developed a method that increases the signal strength from microbial electrochemical cells by up to twenty times. The secret is a film with an embedded bacterium: Shewanella oneidensis. Adding bacteria …

Making it crystal clear: Crystallinity reduces resistance in all-solid-state batteries

“Scientists at Tokyo Tech examined the mechanisms behind the resistance at the electrode-electrolyte interface of all-solid-state batteries. Their findings will aid in the development of much better Li-ion batteries with very fast charge/discharge rates. Designing and improving lithium-ion (Li-ion …
