Timonel - ATtiny85 I2C Bootloader

“Timonel is an I2C bootloader for ATtiny85 microcontrollers. The aim is to enable AVR firmware updates in scenarios where there is a more powerful MCU (ESP8266, Arduino, RPi, BeagleBone, etc.) acting as I2C master and one or more Tiny85 as …

Tufts scientists grow functioning human neural networks in 3D from stem cells

“Neural models could improve understanding of neurodegenerative and other diseases, and facilitate discovery of treatments A team of Tufts University-led researchers has developed three-dimensional (3D) human tissue culture models for the central nervous system that mimic structural and functional features …

U-M researchers develop small device that bends light to generate new radiation

“University of Michigan physicists have led the development of a device the size of a match head that can bend light inside a crystal to generate synchrotron radiation in a lab. When physicists bend very intense beams of charged particles …

Understanding the building blocks for an electronic brain

“Computer bits are binary, with a value of 0 or 1. By contrast, neurons in the brain can have all kinds of different internal states, depending on the input that they received. This allows the brain to process information in …

Using IoT to Remotely Control a Robotic Arm

“Controlling a robotic arm to pick up and drop objects is difficult enough, without IoT it would be near impossible to do this remotely. Story Introduction I really wanted to try was designing a robotic arm completely from scratch. There …

UTA researchers optimize electricity distribution networks

“A team of researchers from The University of Texas at Arlington is combining several principles of machine learning to enable machines to control power networks and other complex dynamic systems more effectively during unexpected events. Frank Lewis, the Moncrief-O’Donnell …

WiFi WebSocket Remote Robot

“This instructables show how to use ESP8266 module as a HTTP + Web Socket server to build a low lag time (fast response) WiFi remote robot. There are tons of WiFi remote robot on the web. Most of them have a …

World’s fastest camera freezes time at 10 trillion frames per second

“What happens when a new technology is so precise that it operates on a scale beyond our characterization capabilities? For example, the lasers used at INRS produce ultrashort pulses in the femtosecond range (10–15 s) that are far too …

3D-printed lithium-ion batteries

“Electric vehicles and most electronic devices, such as cell phones and laptop computers, are powered by lithium-ion batteries. Until now, manufacturers have had to design their devices around the size and shape of commercially available batteries. But researchers have developed …

3D-printed supercapacitor electrode breaks records in lab tests

“Advances in supercapacitor technology could lead to wider use of fast-charging energy storage devices and novel designs for electronic gadgets Scientists at UC Santa Cruz and Lawrence Livermore National Laboratory (LLNL) have reported unprecedented performance results for a supercapacitor electrode …
