    Magnetic levitation

    Just a funny thought on this subject: If all the belt buckles are torn from every Texan, at least returning them would be somewhat simplistic as they usually have the name of the person wearing it on them. LOL Just kidding of course. I am wondering though, what is the application? Lifting...

    New type of bearing?

    Hello all, I can easily see the potential use and practicality of such a bearing/seal combination. Not only does it allow for ease of installation, but cuts costs in many ways. No special materials or machining practices need be employed to utilize such bearings. Why not utilize the hard...

    How to Measure Life Span of DC Motor

    Hello Yanco, GusD is completely correct. My suggestion, would be to create a specialized scenario, where you know exactly how the motor will be used. Collect all variable data not only of the machine in question, but its working environment as well. Example: if a motor is to sink...

    mechanical devices

    I am designing a fully mechanised chair. I have a prototype in progress now. Maybe there is something I can help you with? Don't worry, I am not designing a lounge chair! My chair actually gets larger and smaller to fit the person sitting in it, as well as the ability to adjust all angles...

    Ultrasonic transducer driver circuit

    I know this sounds a bit much, but personaly, I would simply capture a male mosquito, and record its sound. More than likely, you will need to increase the gain on your pickup, but most importantly, you should use a frequency shifter circuit, to bring the sound within your range of hearing...

    Ultrasonic transducer driver circuit

    One special note regarding such devices. Beasts of the world tend to develope an immunity to sounds that would initialy cause them to "flea" the area.. LOL.. If you wish to repel mosquitos, I would suggest you find out what the particular frequency the male emits. This sound, is not...

    custom consruction of laser light systems

    Try browsing through this wegsite's laser pages. You may have to type "lasers" into the search window on the homepage. There should be four pages of plans and kits available. You should find what you need there. http://www.amazing1.com/

    Was an OSHA representative not able to supply you with such information?

    Laser diode sources (Where to buy)

    What you are fighting here, is bulk pricing in manufacturing. If you cannot source such laser moduals, for less money, then simply buy the pens. You will actually save money, as long as you don't mind having to salvage them from the pens. Not only do you get the laser modual, but you also...

    WHERE CAN I FING A SOURCE FOR MOTORS IN CAD SOLIDS

    Yes, there is. But, it really depends on the manufacturer. I get the CD's from the Thomas Register, which have such files from the manufacturer. Some companies provide only 2D imgages for CAD, others have both 2D and 3D solids. Go to Thomas Register online, and ask for the CD's. They will...

    Underwater laser

    IRstuff, Ok, in respect to range gating, in this application, would you suggest adjusting the attack and release time controls of the gate, or simply use abrupt gating? If adjusting the gate on/off thresholds, would you suggest using a method such as hysteresis, to raise the gate open...

    Underwater laser

    Hello HVACctrl & IRstuff, Yes, that link is a good one. I was quite pleased to find it. I spent roughly twelve hours finding a site that had all the details of laser ranging and imaging. Not an easy topic to find this sort of detail! Do not worry about others seemingly doing more work. It is...
