How is 3D printing changing the future of prosthetic and animatronic limbs? Tinkering with this new technology 17-year old inventor Easton LaChappelle is creating robotic limbs with strength and dexterity beyond human, and will create new models for custom prosthetics in the not-so-distant future.
Watch how the new BMW F30 3-Series is manufactured from start to finish in Munich, Germany.
Scared of superintelligent AI? You should be, says neuroscientist and philosopher Sam Harris — and not just in some theoretical way. We’re going to build superhuman machines, says Harris, but we haven’t yet grappled with the problems associated with creating something that may treat us the way we treat ants.
Automation in the Information Age is different. Books we used for this video:The Rise of the Robots; The Second Machine Age.
This tutorial covers the following: * Some history about electricity / central power stations / electrification. * Science of electron flow in a conductor / wire * I use fluid dynamics in a pipe to explain voltage (pressure), current in Amps (flow) and consumption in Amp hours (rate of flow). * We look at AC (alternating current) and DC (direct current) on the UNI-T UT81B scopemeter * We look at how voltage / pressure is required to charge a 12 volt battery * What is electricity? / How does electricity work?
This tutorial Contains the following: * introduction * boot process * basic input/output * simple computing * optical sensors scanning disc * controlling an H bridge * analog inputs (ADC) * controlling servos * improving the homebuilt wiper servo * PID control loop * soft start and emergency stop * controlling a combustion engine * linear servo with digital sensor
A closed loop control system for position control is comprised of proportional, integral, and derivative circuits and is often referred to as a PID.
There are some different of Modbus and Profibus which are sometimes called “Fieldbus”. It is a common name used to tell any network industry that links the field devices. As a generic explanation it was fashionable at one point, but looks to have fallen out of use in recent times. It is also occasionally applied as the simple form of a particular protocol called Foundation Fieldbus. It is only one more protocol such as Profibus or Modbus, but it has attributes which are planned specifically for industrial processes. It was also used as the short form for a…
Computer systems used within the industrial sector are connected by networks known generically as Fieldbus. Learn more about what a Fieldbus system is and what it does.
This video continues the topic of PID control. We walk through a simple control system and visualize how each of the three paths, P, I, and D, all address specific problems that arise in a typical system. I try to use very little math in this lecture because I want to show you that at the foundation PID control is very intuitive. Most of it you can reason through.
Gardening in the modern age means making things more complicated and arduous, with electrons, bits, and bytes. Behold: the garduino. My brother got me an arduino microcontroller board for Christmas, which to me was a solution looking for a problem. I finally found the problem: fresh herbs are expensive at the grocery store. But apparently not as expensive as adding a bunch of sensors and electronics to your garden. Build one yourself or just poke around in the code: https://github.com/gradyh/GradyHillhouseGarduino Moisture sensors that measure the resistance or conductivity across the soil matrix between two contacts are essentially junk….

In this video we build a very useful intruder alert using Arduino. The project is very easy to build and the cost of it is very low. All you need is an Arduino Uno, a GSM shield, a PIR sensor, and a DS3231 rear time clock. You can buy all these parts from the links below. The project, when it detects motion, it sends an SMS to a predefined telephone number! That’s a great project to build and protect your belongings!
This is a GSM Based Security Alarm System project using Arduino Board.

AC motors can be divided into two main categories – (i) Synchronous motor and (ii) Asynchronous motor. An asynchronous motor is popularly called as Induction motor. Both the types are quite different from each other. Major differences between a synchronous motor and an induction motor are discussed below.
Wanna start diagnosing some of those electrical system gremlins yourself? In this video I take you through all functions you’d use for DC circuits using simple examples you can try yourself.
This video compares a 10 dollar to a 170 dollar multimeter and shows the average person how to use the voltage, current, resistance, continuity, diode and battery options. I also cover safety concerns and run all tests simultaneous with both multimeters. This video covers: Difference between 3 and 4 probe options on a multimeter. Tests include: * Voltage of Battery (DC) * Voltage of Outlet (AC) — discover something interesting in one of my outlets — discover a SERIOUS hazard with the 10 dollar meter * Current of a toaster (LIVE) * Resistor test * Metal tape test?…
