3D printed electrodes free the gas

“Alkaline water electrolysis has been touted as a path to establish a hydrogen economy by converting intermittent renewable energies into clean hydrogen-based chemical energy. However, current technology has achieved only low current densities and voltage efficiencies. To make electrolysis more …

7 Segment Clock - Small Printers Edition

“Yet another 7 Segment Clock. xD Although I have to say it doesn’t look that crazy when watching my Instructables profile. It probably get’s more irritating the moment you have a look at my thingiverse profile. So why …

A new graphene-based nanoscale sensor enables detection of a single carbon dioxide molecule - Breakthrough for future environmental sensing technology

“A research group at School of Materials Science / Energy and Environment division at Japan Advanced Institute of Science and Technology (JAIST, President Testuo Asano), succeeded to detect a single CO2 molecule electronically by using a newly developed nano-scale sensor device …

A robot that tells growers when to water crops is on the way

“Every backyard gardener knows how hard it can be to tell when to water the plants. Multiply that by tens or hundreds of acres and it’s easy to see the challenges growers face keeping their crops healthy while managing …

A Simple Raspberry Pi Electronic Organ Based on MPR121

“I am a big fan of TwoSetViolin, they bring me a lot of fun and I start to appreciate the joy of music since I followed their channel last year. They have a program called LINGLING40HOURS, in which there are …

Alexa IoT TV-Controller ESP8266

“Recently I bought an Amazon Echo Dot during the Amazon Prime day for ~20€. These small voice assistants are cheap and great for DIY Home Automation if you know what is possible and how to build smart devices. I have …

An obstacle avoidance system for flying robots inspired by owls

“When developing robotic systems and computational tools, computer scientists often draw inspiration from animals or other biological systems. Depending on a system’s unique characteristics and purpose, in fact, nature typically offers specific examples of how it could achieve its …

An origami-inspired robotic fingertip with shape-morphing capabilities

“To perform tasks that involve moving or handling objects, robots should swiftly adapt their grasp and manipulation strategies based on the properties of these objects and the environment surrounding them. Most robotic hands developed so far, however, have a fixed …

Analog Light Sensor + Light Sensitive Switch using OPT101

“You may have seen many light-sensitive switch circuits based on an LDR sensor. Usually, the sensitivity of the LDR based light sensor is poor. We wanted a very sensitive light switch hence we decided to make a circuit based on …

Arduino Nano 33 BLE OV7670 Camera Shield

“Embedded machine vision board, make your robotics ML enable. Arduino Nano 33 BLE processing capacity is moderately high for the low power consumption embedded system. Since it has many sensors on board, it seems to be very fun to run …
