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.
 

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
