very helpful! Thanks for showing both the motors working!

Now you have to see how it sounds stuck to the inside of the case. I find the visual feed back is ok for me, as i drive the screen functions with it.

Great video!

I ordered the two vibrating devices that you featured in this video. Thank you for putting the Alibaba Express links in the description. I will be using them with a brand new Arduino UNO R4 Wifi device. The 8 octave (8x12 matrix) that is on that development board will work as a preliminary mock-up for the MIDI note indicators. Later, I will add a strip of addressable RGB LEDS and later a matching one of haptic devices - and maybe one of the two types that you suggested will be on that haptic strip. Thanks again.

Sounds very cool! Looking forward to see the result somewhere. I liked the second motor better for haptic feedback. But my guess is it will heavily depend on where and how you mount the motor how good the haptic feedback will work. Beyond this video I have not done anything with thee motors, but the idea of using this with a screen is still alive. So thanks for bringing this to my attention again. Need to do some more experimenting :D

Cool stuff

the diode across the motor will help absorb the collapsed back emf after the forward drop is overcome, but does all the energy flow through the diode, current will follow least resistance path some might enter the collector also.

Yes correct. But if implemented correctly not enough to destroy your transistor. But still think about the size of the collapsed EMF and choose you diode and even your transistor to not be destroyed.

Thank you, no problem! For this simple application will do, but preferred are Schottky diodes. Because they have a lower forward voltage drop and will react faster when reversed biased. Something in the 1N58xx is fine for this.

I need to develop a system for swimming kids that warns when is getting close to end

My intention is to use a vibrator and ESP to trick the electronic park disc to think you’re driving. So I can reset the time since parked by sending a sms😊

The second motor (the coin one) looks like its from a cell phone. don't know if it actually is or not but still pretty cool.

I think they use motors that are much smaller. And the motor you are talking about vibrates pretty heavily.

I've been curious about using some similar vibration devices to trigger the recording of a car dashcam when in 'parking mode'. They will wake up and record with a sudden impact when parked, but there are a multitude of scenarios I'd like to capture that may not set off the g sensor when in parking mode. For this, I plan to use the car alarms siren as a trigger (mine only gives audio feedback when triggered, not when locking/unlocking), as well as a dual stage proximity sensor. This should cover my worries, which include people getting too close/prying inside my tinted windows. Previously I thought of using a timer relay to give the dash cam 12v on its Ignition input, thinking that the vehicle is turned on and immediately recording. But if the alarm triggered a recording I have no way of knowing it occurred and the dashcam could record over said clip. By triggering the gsensor in parking mode instead, all parking mode clips get saved to a different file that can't be recorded over, and the dash cam warns yousomethjng happened when turning the vehicle on.

‏‪4:55‬‏ What kind of diod I should use?

@DustinWatts

Жыл бұрын

Just a normal 1N004. Depending on hirger currents you good go with the 02 or 03. But the diode is more important than the type of diode. 2n22222 will also work fine. So will a 1N4148.

Thank you very much for this beautiful video, but I want to ask you something because I am an Egyptian student and I am working on a scientific project and I will use these. What is the difference between using ESP or Arduino and which is better? Why did you use diode? Why did you use a transistor? Are they very important and indispensable? Is there any way to control the frequency? For example, I want a period of 50 Hz and a period of 250 Hz. Can I in any way control that?

How can i mount a circuit to connect this motors to work with an Audio Signal? In my case i need to connect this motors on parallel so they could work all with the same audio signal

@DustinWatts

4 ай бұрын

Depending on the voltage level of the audio signal you can connect it directly yo the audio signal. If you are afraid there is a mismatch or generally a better way is create a motor driver with a steady 5V using a transistor and an OpAmp buffer to not load down the audio signal. The simplest way is in this circuit, change the signal from the microcontroller and plug in the audio signal.

Can we specify the frequency?

@DustinWatts

There is no direct way to specify the frequency. But depending on the voltage you can influence the RPM which will have a slight effect on the frequency. But these are not made to change the frequency. They do exists though, but are a lot more expensive.

Hi @Beau400! That is a lot of questions :) 1. An ESP and an Arduino a both boards with a micro controller. I like the ESP32 better because it has Bluetooth (also Bluetooth Low Energy, BLE) and WiFi. 2. The diode is to protect the transistors from the high voltage spike that can occur when using a motor. This spike now has a place to go (trough the diode and motor) instead of destroying our transistor. 3. The transistor is there so I can use a higher voltage and higher currents then an ESP32 pin can provide. I connect it to 5V. Which I cannot do directly to the ESP32 because it is a 3V3 device. 4. So no, they are not indispensable. 5. In the code you can change the frequency of the PWM signal that is connected to the base of the of the transistor. However I would change the duty cycle to get lower or higher frequencies. That is much easier. (there are a lot of tutorials on KZread how to do that). Thanks you for your comment and for watching my video! I hope you got something out of it!
