Does Cold or Hot Water Boil Faster? RimstarOrg 2013-08-09 | This answers does cold water or hot water boil faster and why might many people think cold water boils faster than hot water. I do some rigorous science experiments to find the answers and explain the different rates of heat transfer when there's a big temperature difference versus when there's a small temperature difference. At the same time, I also show how to use a thermistor inside an automobile coolant temperature sensor instead of a cooking thermometer for these experiments.Addendum: It's been pointed out that as temperatures reach boiling the reason for the slow down in temperature change is most likely because more energy is going into evaporation instead of increasing temperature.See also,"Thermistor from Coolant Temperature Sensor"(coming soon)"Steam Vacuum - Making/How it Works"http://youtu.be/Tm3f1MfrWdM"What is Fire"http://youtu.be/V3sV8t_HUdcFollow behind-the-scenes on:Twitter twitter.com/#!/RimStarzGoogle+ plus.google.com/116395125136223897621http://rimstar.orgA Darker Heart - music by audionautix.com
Izzys Two-Eyed Robot Object Recognition and Fixation RimstarOrg 2022-11-26 | Izzy not only has two eyes like a human but does object recognition with both eyes, picks an object and fixates on it, following it around the room. It uses the Yolo 3 neural network running on the darknet neural network engine. The brains are an NVIDIA Jetson TX1 with an arduino mega 2560 for motor control and two YoLuke webcams for the cameras.

LC Circuit: Selecting Coil and Capacitor RimstarOrg 2017-04-27 | ERROR!!!! The correction is that whenever the capacitor is discharged, the current it at maximum. At 1:45, 2:37 and 2:49, I remove the arrows to indicate that the current is zero while the capacitor is discharged. I shouldn't have removed them. In fact the arrows are moving in the same direction before and after those points and the arrows are thickest, meaning maximum current! How can it possibly be maximum, then zero, then maximum?! My bad. It's shown better in the animations starting at 3:16.How to select a coil and capacitor for an LC circuit, using a crystal radio as an example.

Making BB-8 (v2) - How to Fiberglass - Part 2 RimstarOrg 2016-04-30 | How to do fiberglassing to make a more rigid ball for my BB-8 (v2) droid. The ball is just a cardboard globe, and with the weight of BB-8's drive system inside, the globe deforms a lot. After showing step-by-step how I put 3 layers of fiberglass on the globe, it's now so rigid that I don't notice any deforming.This video was made possible in part by these Patreon supporters:Jonathan RiekeJames PaddenSupport RimstarOrg on Patreon patreon.com/user?u=680159or make a one-time donation at http://rimstar.org/donate_support_rimstarorg.htmSubscribe so that you don't miss new videos as they come out http://www.youtube.com/user/rimstarorg?sub_confirmation=1Go to the main channel page here youtube.com/rimstarorgSee also:Making BB-8 Droid (v2) - Part 1youtube.com/watch?v=BCXH4AN2aog&list=PLFsZmHTZL-zmfXxstlxuJgRE9bOGobEVuBB-8 Star Wars Droid - Homemade (latest version)youtube.com/watch?v=5EuI9lBtC3I&list=PLFsZmHTZL-zmztc_P7h2tqLxKJHu0vH1ePeltier Module Cooling - The Peltier Effectyoutube.com/watch?v=9Cuh2msd2lo&list=PLFsZmHTZL-zn3jrI0X0e0aRijWlyvfg8hFor my BB-8 (v2) webpages go to:http://rimstar.org/science_electronics_projects/bb-8_star_wars_droid_v2.htmFollow behind-the-scenes on:Twitter twitter.com/#!/RimStarzGoogle+ plus.google.com/116395125136223897621Facebook facebook.com/rimstarorghttp://rimstar.org
Backpropagation Neural Network - How it Works e.g. Counting RimstarOrg 2016-04-15 | Here's a small backpropagation neural network that counts and an example and an explanation for how it works, how it learns. A neural network is a tool in artificial intelligence that learns how to do things instead of be hand-coded. Recently it's been popularized with Google's deep dreaming neural network and Deepmind's AlphaGo beating world champion Lee Sedol at the game of go.My webpage with all the demo, neural network source code, and so on that I talked about is at:http://rimstar.org/science_electronics_projects/backpropagation_neural_network_software_3_layer.htmThis video was made possible in part by support from:Jonathan RiekeJames PaddenSupport RimstarOrg on Patreon patreon.com/user?u=680159or make a one-time donation at http://rimstar.org/donate_support_rimstarorg.htmSubscribe so that you don't miss new videos as they come out http://www.youtube.com/user/rimstarorg?sub_confirmation=1Go to the main channel page here youtube.com/rimstarorgSee also:Does Volts or Amps Kill You?

Remote Control Drill Motor & How a MOSFET Works RimstarOrg 2015-10-03 | WARNING - The drill battery in the circuit diagram is drawn backwards by accident. The plus sign beside the drill battery should be a minus and the minus sign beside the drill battery should be a plus sign. That means some of the red and black lines should reverse colors too. The black lines going to and from the drill motor should especially be red for clarity, just as the red line going to the source should be black for clarity. Everything else in the video, including how the circuit is ACTUALLY wired up and the MOSFET explanation is correct.
