“Been playing around with the laser cutter/engraver, and really fell in love with engraving in to clear acrylic and shining a light source from the edge. The thickness of the acrylic being used is a .25” sheet, which cuts …
“A thorough study published on NanoLetters and led by the ICN2 Advanced Electron Nanoscopy group provides new insights on the growth mechanisms and conditions that determine the polarity of semiconductor nanostructures. Fine control of polarity can result in the design …
“For my latest electronics project, I’ve built a small USB keyboard input device for media control. The final version has three keys: play/pause, previous track, and next track. In addition, a rotary encoder allows adjusting the volume (or …
“The compact coil could lead to a new generation of magnets for biomedical research, nuclear fusion reactors and many applications in between. Any featherweight who steps into the ring with a heavyweight must either be crazy or harbor a death …
“Summary This PCB (Printed Circuit Board) resembles the YouTube Play Button award that is given out to creators for reaching certain milestones such as 100,000, 1 million, and 10 million subscribers. When the switch is turned on, the user …
“The 1750Hz tone bursts are often used to trigger repeaters. There are several methods to build 1750Hz tone generators which including TC5082 divider, using MCUs, etc. In this post, I present another 1750Hz tone generator which I built using 74HC4060 …
“A team led by scientists at the Department of Energy’s Oak Ridge National Laboratory explored how atomically thin two-dimensional (2D) crystals can grow over 3D objects and how the curvature of those objects can stretch and strain the crystals …
“Most of my DIY projects make use of a 3D printer. The big advantage is that you can design and make your own 3D objects. In a previous instructable I’ve assembled and improved an Anet A8 3D printer. And …
“MIT startup Inkbit is overcoming traditional constraints to 3-D printing by giving its machines “eyes and brains.” Objects made with 3-D printing can be lighter, stronger, and more complex than those produced through traditional manufacturing methods. But several technical challenges …
“Researchers from Skoltech Center for Energy Science and Technology, IPCP RAS and D.I. Mendeleev Russian University of Chemical Technology have created a new polymer cathode material for ultrafast metal-ion batteries with superior characteristics. The results of this work were …
