We bought good-quality Panasonic batteries in quantity from Allied Electronics for 26 cents each. Each lab period typically consumes half a dozen 20-cm (8-in) lengths of tape, so one tape is sufficient for about 10 lab periods. Upper (U) Rite-Aid tape is charged negatively, whereas with Scotch brand Magic(TM) Tape a U tape is charged positively. We got 500-inch tape, a half inch wide, on sale for 50 cents. Invisible tapeįor the electrostatics experiments we use a cheap local drugstore brand of invisible tape. One also needs a small supply of aluminum foil and thread for electrostatics experiments, and unmagnetized iron nails (3 per student) for some magnetism experiments. In other institutional settings one might choose to have kits available in a formal lab setting and not have individual ownership. One scheme is to issue each student a kit and charge a lab fee to cover the cost, or rent the kit for a semester. If you find a better source for any of these components, please let Ruth Chabay or Bruce Sherwood know, and we’ll post it here.Īn experiment kit contains the following:Ģ 18-inch (45-cm) lengths of Nichrome wire, #26 and #30 gaugeġ 6-foot (about 2-meter) length of hookup wireġ takeout Chinese-food box (4 in. We recommend buying kits, because they are of high quality, and it is more difficult than you might imagine to procure all of the pieces you need. If however you prefer to assemble your own kits, we offer detailed procurement information gleaned from an earlier period when we assembled our own kits. Whether these experiments are done in a formal lab setting or in a lecture hall, they provide important experience in reasoning about phenomena.ĭesktop experiment kits are conveniently available from PASCO (item EM-8675). 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.Desktop experiments in electrostatics, circuits, and magnetism are integrated with theory in Volume 2 (Electric & Magnetic Interactions). 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.

#Light bulb experiment radioshark code#
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.
