“Component video (YPbPr) output for the ZX Spectrum computer General The ZX Spectrum in its original form produces a radio frequency signal that can be fed into an analog TV. The quality of this signal is very poor, but this …
“This project will show you how I went about designing and building an Arduino based RC Transmitter. My goal for this project was to design a 3D printable RC Transmitter that I could use to control other Arduino projects. I …
“This was my first project working with the Arduino Pro Micro. You can use it in Zoom or Discord chats to do things like toggle mute, toggle your video, or share your screen. On top of that, you can program …
“Hello everyone, after changing flat, since my singing skills under shower are probably not appreciated by my old neighbours, I decided that I needed a tiny bluetooth speaker for my bathroom. Playing music directly next to the shower would, at …
“Researchers at the Department of Energy’s Oak Ridge National Laboratory are refining their design of a 3D-printed nuclear reactor core, scaling up the additive manufacturing process necessary to build it, and developing methods to confirm the consistency and reliability …
“Tests on new designs for next-generation solar cells can now be done in hours instead of days thanks to a new system built by scientists at Australia’s Monash University, incorporating 3D-printed key components. The machine can analyse 16 sample …
“This is a minimal and small clock based on PIC16F628A microcontroller and DS1307 RTC IC. It is able to only show the time on a small 7-segment display with a total of 4 segments. The display we used is a …
“NUS researchers have created a whole new library of atomically thin two-dimensional (2D) materials, christened “ic-2D”, to denote a class of materials based on self-intercalation of native atoms into the gap between the layers of crystals. Atomically thin two-dimensional (2D …
“Researchers at Universidad Carlos III de Madrid (UC3M) have patented a new spatial plasma-fueled engine capable of satellite and spacecraft propulsion, with magnetic field geometry and configuration that would minimize losses on walls and their erosion, thereby resolving issues of …
“One of the shortcomings of using an older communications gear is the fact that the analog dial isn’t very accurate. You’re always guessing at the frequency you’re receiving. In the AM or FM bands, this generally isn …
