Light bulb experiment radioshark1/5/2024 Also, the entire light glowed brighter when 2 scientist touched the light and nothing else. If a second scientist, who was holding nothing else, touched the light, we noticed that the light glowed brighter near their hand, too. We also noticed the that the brightest area on the light was where the scientist held the light. The higher we held the lights, the brighter they glowed. The lights glowed under the most powerful electric lines. Results: The lights did not glow under the least or second to the least powerful power lines. The lights will be held under the power lines starting with the least power working up to the lines with the most power. The third scientist will attempt to capture the results on camera. Procedure: Two scientists (my lovely kids) will each hold a fluorescent light while standing under each type of power lines and observe whether or not they glow at night. Materials: 2 Fluorescent light bulbs, 3 scientists, a camera. Hypothesis: The light bulbs will glow under the most powerful electric lines, but while under the other power lines. My kids thought it would be fun to find out if the myth is true that fluorescent lights would glow underneath power lines. Next is a more powerful set of lines, followed by lines that are powerful enough to hum (I tried to find information with more specific details about the power lines, but was unsuccessful). Near our house, we have three different types of power lines. Since we love to learn by inspiration, we took the idea and ran with it. Thanks to the suggestion of one of this blog’s readers, my 9 year old son wanted to do an electricity experiment involving Fluorescent Light Bulbs (used in a science fair experiment by my 11 year old) and Power Lines. Also as stated above, you can turn both lights on at once to get purple.Īs for me hooking it up into an automated build system…I never got around to it.This page may contain affiliate links designed to provide a means for sites to earn advertising fees by advertising and linking to other companies. The blue light also supports a “pulse” mode, but it’s kind of useless, so I didn’t bother providing any way of turning it on. You’ll note that the Blue light has a fader, so you can set its brightness to anything between 128 (fully on) and 0 (fully off). #Turn blue halfway on, and red on, gives a nice purple ![]() r Set the red light brightness, values are 0 and 128. b Set the blue light brightness, value range is 0 to 128. ![]() It comes with both the source code, and a pre-compiled binary. The result is “rslight”, which you can download here. ![]() And after ripping the USB HID code out of Audio Hijack Pro, that’s what I built. For this I just wanted a simple command-line tool that could be invoked from a shell script. So with that problem tackled I moved on to the next one, actually controlling the RadioSHARK’s lights programmatically. You can get a third color, a weird shade of purple, if you turn both blue and red lights on at once. The RadioSHARK is a USB-controllable light! It’s a bit expensive to use just as a light bulb, but if you already have one, why not? It even supports does two colors, blue and red. But then while working on RadioSHARK support for Audio Hijack Pro 2.5, it hit me. They make USB toothbrushes, but not USB lights. The hang-up I always ran into with this was finding a USB-controllable light. In fact, it’s been done many times before, and for things other than software projects. ![]() Once something like this is set, knowing the status of the source tree is a simple matter of glancing at the light. If everything was ok, the light would stay off, but if something failed it would turn on. All the projects would be automatically built, and their unit tests would run. The setup would be fairly simple: whenever a change is checked into the source code repository, an automated build (and test) would be triggered. Posted By Quentin Carnicelli on May 23rd, 2005įor awhile now, I’ve wanted a USB-controllable light, to connect into an automated build system for our projects.
