Everyone loves watching movies, that is, so long as you can hear what the characters on screen are saying. [GreatScott] found this second part difficult while watching through BladeRunner 2049, so he designed an automatic volume adjuster to assist. At a high level, the solution is fairly straightforward; when there is loud music playing in a

When your friends are off to the post-apocalyptic Wasteland Festival and present you with a defunct Power Wheels clone toy Jeep to make ready for the festivities, what are you to do? If you happen to be [Victor Frost], soup it up with new electrics and uprated steering, and send it forth into the hideous no-mans
The Neewer NL660-2.4 Video Keylight has a handy remote control, which for [Tom Clement] has a major flaw in that it can’t restore the light to the state it had during its last power-on. He’s thus taken the trouble to reverse engineer it and create his own remote using a suitably-equipped Arduino clone. The write-up is a

Here I will show how I made a “Remote Social Touch” early prototype. This was made for an explorative stage for my PhD, however, anyone can make their own and alter as they wish to generate their own final version. “Remote Social Touch” (RST) basically is a way to send or receive physical touch massages
SolidRun has announced pre-sales for $550 for its developer-oriented “early access” edition of a high-end networking board that features NXP’s 16-core, Cortex-A72 LX2160A. The beta-stage HoneyComb LX2Kearly version board will ship in September, and the $750 model with extra features will go on sale in October 2019. The HoneyComb LX2K is a sandwich-style board designed based on a COM Express Type 7 module, and it’s equipped with 2x 10GbE SFP+

In today’s Instructable, I’ll show you how you can use a generic RF module without a microcontroller which will eventually lead us to build a project where you can convert an IR Remote of any device to a RF Remote. The main advantage of converting an IR Remote to RF, is that, you don’t have
New modulation method increases operational lifetime of switching power units through digital, highly dynamic control and the use of film capacitors. Switching power units are used for the power supply of many electrical devices, e.g. computers, LED lights or laser welding equipment. They convert alternating current from the mains into the direct current required by
