Composite video standard defines a signal with 1Vpp amplitude under a 75 Ohms. From that signal 70% (0.7V) is the amplitude of video information which stands above a 0.3V pedestal, while the synchronism information (sync tip) corresponds to the remaining...
Intro Soft robotics is a field that has fascinated me for the longest time. Though the research field is maturing, I still haven't seen many hobby level soft robotic projects. Starting with no prior experience, a little more than a year ago I got to...
Sometimes, when making your own devices on microcontrollers, there is a need to display huge amounts of information on a display and to use a bigger screen for ease of perception. Unfortunately, there are no ready-made and budget-friendly solutions for...
The Expert is a Brazilian manufactured in the 80's and it is compatible with MSX standard. It uses a detachable keyboard but it lacks the Caps Lock LED on the keyboard because the 13 pin connector used ran out of pins (even the shield is used as a 14th...

The ideaI’m David, and my goal with this repository/article is to demystify Sockets by try to explain them in the simplest possible way.In these examples, I’m going to use NodeJS and Particle (any version will do) to show how hardware can talk with NodeJS,...
Dear Sally,Thanks for your postcard! Was that a real antique or one of your amazing replicas? You have a real artistic sense, always have. It made me think back to when I met you, over a hundred years ago now! I would have said it warms the heart to...
Briefly: 80-wire IDE cables are *great* for high-speed stuff... But the pinout is a bit more difficult than a straight-through 40-wire IDE cable, because the 80-wire cables have shielding (yay!) which is connected to specific pins designated as ground,...
As an operating element of mechanical equipment, servo motors get widely used in the servo systems. Sometimes the heating of the operating servo motors may make us a wonder whether it is normal if we lack some professional knowledge. Actually, it...
