AI Thread Summary
To control multiple vibrating motors for timed intervals, a simple on/off mechanism using a DC supply voltage is effective. Each motor requires about 85 mA at a 3V supply, suggesting that a single transistor could be used to manage the power to the motors. For timing, a microcontroller or timer circuit can be implemented to activate the motors every 15 minutes for a few seconds. Additionally, resources such as online electronics tutorials and forums can provide guidance on wiring and programming. This approach will enable the simultaneous control of 20 identical motors efficiently.

Hello,

I am a biology student working on my masters and i have to control a small vibrating motor (like http://www.alibaba.com/product-gs/51129609/dc_micro_motor_vibration_motor_small.html) and have no experience with electronics and such.
i would like the motor to vibrate for a couple of seconds, every 15mins, over the period of 8 hours let's say… the motor is very much like those found in mobile phones. it’s powered by one AAA 1.5V battery.

What do I need to connect it to, in order to control it this way?
second deal: i need to control 20 identical motors at the same time, in the same way..

id be glad to know at least what i need, the devices and maybe ressources to get me further.

Thank you for your time!

Alex

Nothing fancy, just turn the DC supply voltage on/off.

These motors draw about 85 ma at 3V supply. You may be able to drive it with a single transistor.
 
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
