Blender cool effects

So I really like the program blender. I enjoy using it, but I am not very good. I thought it would be cool, though if there was a place where people could share cool effects they made in blender, so this is the purpose of the forum. If you made a video with a cool effect in blender, post it here or link it here, I would love to check it out :D

cooling laptop processor? Answered

I am using a dell inspiron 640m (i call it lappy dino) few years old now the processor is an intel core duo T5200 i use my laptop as a desktop because its screen is fried, meaning it never moves and uses an external monitor i have 3 questions here 1) i have been forcing my fan to run at maximum + a cooling pad blowing air towards the intake vent,   so far my cpu temp dropped from 60-70 Celsius to a nice 45 degrees the question is, would         running my fan at max damage anything or itself? 2)is there any risk of making your cpu "TOO COOL" and how will it hurt the computer 3) would it be better to remove the   heat sink plastic cover like in the picture  ,just the heat sink cover(the picture shows all cover removed) and not the heat sink itself then blow air directly at it with my cooling pad

Power supply cooling

I'm building a power supply for my cnc machine that gives off about 37volts at 8 amps, and 12 volts at 0.9 amps. All of the transformers are from radioshack (using 6 heavy duty, 25.2volts, 2 amps transformers, 4 in parallel giving off 25.2 vdc at 8 amps, and 2 12.6 volts in parallel. Together in series gives about 37 volts at 8 amps. using 1 25.2 volts 450mA transformer, center tapped) My case does not have enough room for proper cooling such as fans. My case is water tight though, should I fill it up with something like mineral oil to keep the transformers cool?

Laptop Cooling Question

I'm using a laptop-sized, vented, inverted vegetable tray to keep the laptop cool. It's quite effective even without any fans in this scorching heat. I added a CPU fan underneath ( 12 V, 0.42 A), and ran it off a USB cable from the laptop. The air is quite nice, but one thing I'm a bit worried is, when I touch the top of the laptop, it slightly vibrates constantly due to the fan underneath. Is that dangerous for the laptop? I'm planning to add another fan beneath the hard disk. The one I have now, is under the laptop's CPU fan. Another thing I would like to know is that, is it okay to run two fans of 042 A each, from two USB ports? Each USB port can supply 0.5 A max current. Running one fan off each port should be okay? But, today, the temperature was quite high in the afternoon, nearly 50 degrees! I'm thinking of buyin a readymade laptop cooler.

power supply cooling

Normally I'm pretty good with electronics, but I need some help with this problem. I'm building a power supply for a cnc machine and I need help designing a circuit to power fans when it's over a certain temperature. Here's some things it needs: 1) 12 volts supply (easy with a transformer and filtering it) 2) power fans when it reaches a certain temperature. 3) still keeps the fans on even though the rest of the system is off. 4) after the system if off and it's down to temperature then the transformer turns off, to save electricity and to not make it hot after a long time. If possible can someone draw up a schematic? Thanks in advance!

Insanely Cool Multitouch

So now all I need is $100k and I'm ready to rock. watch the videoJefferson Y. Han likes big computer monitors. If a screen is large enough, four or five people can work at it together, rearranging blueprints, say, or editing photos. But they can't do that if they're taking turns at a keyboard and mouse. The answer, which Han demonstrates on a 3 x 8-ft. monitor in his lab at New York University, is multitouch input. It allows any number of users to lay hands on the screen as if they were manipulating real objects. On the monitor, recently dubbed the Media Wall, Han uses his hands to spin a virtual globe and then zoom into the canyons of Manhattan. "A mouse is an indirect pointing device," Han says. "You're working with an object that's not on the screen. Multitouch computing is direct manipulation."Han, the son of Korean immigrants, drew inspiration from the way light diffuses when you touch a glass of water. It's a phenomenon known as "œfrustrated total internal reflection." Han attached LEDs to the side of a piece of clear acrylic ”his screen" and mounted an infrared camera on the back. Light traveled through the acrylic. When Han touched the screen, some light diffused out and was captured by the camera. He then designed software that allows the screen to be used for operating mapping programs, handling photos and drawing animated figures. Perceptive Pixel, the business Han started with an NYU colleague, builds custom multitouch computers for private industry and military clients (and, now, to anyone with $100,000).Multitouch computing isn't new: the concept has been kicking around since the 1980s, and two Breakthrough Award-winning products, Apple's iPhone and Microsoft's Surface, use versions of it. Han's special contribution: Beyond his varied applications for multitouch computing lies a broad vision of how it can empower people to work together in new ways.

Cool Batch applet

Hey whats up the names Jason. I am 13 and like to play with computers but not like Halo (although i am guilty of occasionally playing Halo) what interest me is computer logic and programming. So right now i am half-way decentish with Qbasic and consequently Visual Basic, but the language i am most fluent in is just plain old DOS scripting (batch files). My math teacher at the begging of the year my math teacher announced that once o twice a month we would have a pop quiz on square roots and squares of numbers 1-20. Now to say the least I am poor with memorization. So i tried flash cards and starin at a sheet with the squares and square roots on it. but I was pretty consistently getting 60s and 70s. Now being a pretty good student this upset me and my parents weren't exactly happy. So then i decided i would make a batch file to quiz me on this, my first one was on sqrts. writing this took forever so even still i made another for squares. These programs help me study immensely and i now get a perfect 100 every quiz.. i then started thinking that there must be a way to speed up the writing of a simaler quiz program. thats why i wrote this, and i know it is probably mediocre but i like it so be nice. (You can do whatever you want with this source code, and while not required i would prefer credit if you distribute a mod of this batch file.)Here it is:rem The purpose of this batch is to automate the process of making another batch that is used to quiz a person@echo off:startclsEcho Make a Quizecho.echo.rem this part creates a variabl that wil be used in creating the final batch fileecho enter the name of the fileecho .bat wil automaticaly be tacked ont to the endSet /p filename=echo.echo.rem This just creates a ariable that is the title of the the game to be createdecho now enter the title of the quizset/p title=echo.echo.rem this is where the user inputs question part one and it becomes a variableecho enter question part 1Set /p quespt1=echo.echo.rem this ask for the second part of the question echo enter qeustion part 2set /p quespt2=echo.echo.Rem this declares some variables just for shorthandset line=echo.set ec=echoRem this creates a file that user named a while back and then fills it with some preliminary textecho @echo off>%filename%.batecho :start>>%filename%.batecho cls>>%filename%.batecho echo %title%>>%filename%.batecho %line%>>%filename%.batecho %line%>>%filename%.batrem this part is called midstart because ideally later you can repeat this multiple times depending on how long your quiz isset next=0:midstartset /a next=%next%+1rem now we ask for the question of the questionecho now enter the question for the current questionSet /p questmp=echo.echo.rem now we ask for the answer for that questionecho now the answer to that same questionSet /p anstmp=rem More txt inserting (the %%answer%% is used so that in the batch file being created it shows up as %answer%)echo echo %quespt1% %questmp% %quespt2%>>%filename%.batecho set /p answer=>>%filename%.batecho if %%answer%% == %anstmp% goto next%next%>>%filename%.batecho echo you lost>>%filename%.batecho pause>>%filename%.batecho goto start>>%filename%.batecho :next%next%>>%filename%.batecho echo You got it right>>%filename%.batecho %line%>>%filename%.batecho %line%>>%filename%.batecho you have asked %next% question(s)echo.echo.echo If you would like to make a new question simply type "n" and press enterecho However to input your last question type "l" and press enterset /p endchoice=if %endchoice% == l goto endif %endchoice% == n goto restart:restartgoto midstart:endset /a next=%next%+1rem now we ask for the question of the questionecho now enter the question for the current questionSet /p questmp=echo.echo.rem now we ask for the answer for that questionecho now the answer to that same questionSet /p anstmp=rem More txt inserting (the %%answer%% is used so that in the batch file being created it shows up as %answer%)echo echo %quespt1% %questmp% %quespt2%>>%filename%.batecho set /p answer=>>%filename%.batecho if %%answer%% == %anstmp% goto next%next%>>%filename%.batecho echo you lost>>%filename%.batecho pause>>%filename%.batecho goto start>>%filename%.batecho :next%next%>>%filename%.batecho echo you won>>%filename%.batecho echo !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!>>%filename%.batecho %line%>>%filename%.batecho echo click to exit>>%filename%.batecho pause>>%filename%.batEcho And thats it your doneecho.echo click to exitset /p end=And thats it so have fun and feel free to comment

Temperature sensor with cool thermistor

Hi, I am trying to make a temperature sensor using a thermistor. I've made a basic circuit using an Arduino and some tutorials from this site and couple others, which works well but the thermistor heats up way too much - perhaps to about 50 or 60 degrees - but it needs to stay around room temperature for my application. I'm using a 5V output from an Arduino through a 15Ohm thermistor - am I doing something wrong? Many thanks for the help! The one I've made is almost identical to the one in this tutorial: http://www.circuitbasics.com/arduino-thermistor-temperature-sensor-tutorial/ except a different thermistor

Vortex cooling / heating tubes

I am currently gathering information about vortex tubes for my repulsine project. There are plenty to choose from on a commercial base but I struggle to find any technical drawings with proper dimensions. Several home made varities can be found as well but wither with poor performance or incomplete drawings. So I was thinking that someone here either uses a commercial product at home or work and might be able to take some basic measurements for me? I am most interested in the relation between inner tube diameter and lenght for the hot and cold ends as well as the size for the vortex chamber itself. If there is an orifice used on the cold end the hole diameter would be required as well. My aim is, based on a properly working original, to create a device that might be less efficient but can be used without a compressor. Would like to see, correct transfer of dimensions given, a vortex tube like system was used in the repulsine. Some old documents state that there was a "seperator" which removed "heavy air particles" and created a temperature differencial between top cone of the repulsine and the wave disks.

Laser diode cooling, would sanding help?

Datasheet: http://docs-europe.electrocomponents.com/webdocs/08d5/0900766b808d55b2.pdfUPDATE: Ok, due to many unforeseen minor issues/problems that have arisen, I have decided to consider a flat diode package.
