Bathroom Ventilation Fan Controller

“Now a few weeks in test and performing so well… ! An Arduino controller to very effectively keep the humidity to an acceptable level. WHY (oh why…?) Well I looked for a good solution to keep the humidity level down in …

Breaking records like baking bread

“Researchers have made unparalleled ultrawide-bandgap semiconductors through temperature and timing, just like baking bread. Alloying, the process of mixing metals in different ratios, has been a known method for creating materials with enhanced properties for thousands of years, ever since …

Cellular Signal Heatmap with Raspberry Pi Pico and GPS

“Create a Google Map heatmap with cellular and GPS data acquired by a Raspberry Pi Pico and Notecard, using Python and Google Cloud Platform. A heatmap overlaid on satellite imagery is one of the more tantalizing means of displaying map-based …

Century-old problem solved with first-ever 3D atomic imaging of an amorphous solid

“UCLA-led study captures the structure of metallic glass Glass, rubber and plastics all belong to a class of matter called amorphous solids. And in spite of how common they are in our everyday lives, amorphous solids have long posed …

Chamber Heater For Small Resin Printers

“This heater allows small machines such as the Elegoo mars to print with engineering resins like Siraya Tech BLU or specialty resins. Engineering resins require higher than ambient temperature to print with, 25 C is the bare minimum while optimal …

Cistercian Digital Clock

“Throughout history, people have invented and used many numeral systems, some well-known: the Sumerian, Roman, Indo-Arabic system (which by the way is used by almost all mankind). But there were also times when other systems were used. In this project …

Controlling bubble formation on electrodes

“Study finds the wettability of porous electrode surfaces is key to making efficient water-splitting or carbon-capturing systems. Using electricity to split water into hydrogen and oxygen can be an effective way to produce clean-burning hydrogen fuel, with further benefits if …

Deciphering the secrets of Printed Electronics

“We live in a world where we want our electronics to be flexible, bendable and stretchable apart from being intelligent. Printed electronics technology has emerged as the main route to enable this vision. A team of researchers from Aarhus University …

DHT22 Sensor with 16x2 LCD Screen

“Monitor Temperature & Humidity of a room on LCD Screen using Arduino Mega In this project, we are trying to monitor the Temperature and Humidity of a closed area like a Meeting/Conference room, Cabins, cubicles. So we have connected the …

Discord Security Camera with an ESP32

“Use an ESP32 Cam and a passive infrared (PIR) sensor to create a motion-activated security camera that posts photos to a Discord channel. Use an ESP32 Cam and a passive infrared (PIR) sensor to create a motion-activated security camera that …
