Devo 12s: adding a vibration motor

YES! The vibration alarm in my Devo 12s (PCB Version 1.6A) works pretty well. Quite simply, but electronic expertise is needed. So here is my report and it works on my Devo. I take no responsibility for any damage and you act at your own risk when you are trying to build it.

I've take the signal from the buzzer via an opto-coupler to avoid any damages of the Devo 12s. The opto-coupler can be connected directly to the buzzer, a resistor is not needed. The opto-coupler switches the BD 237 transistor and the motor rotates. The diode, a 1N4148, is needed as a free-wheeling diode to protect the BD 237. For safety reasons I took a small 180mAh 1s LiPo battery for suppling power to the PCB and the vibration motor.

It works with my Devo 12s and again I take no responsibility and you do it at your own risk.

I've soldered a cable direct to the buzzer PCB. At the pictures you can see the connector on the Main-PCB. It´s possible to connect here, maybe with a thin wire or a needle and so the removal of the main PCB is not necessary.

The PCB is in the compartment below the BT3000 LiPo. I drilled a hole in the compartment for the Cables. There are three Cable inside, one from buzzer to opto-coupler LED, the second from the LiPo and the third to the motor. Here you can see the transistor, the opto-coupler and the potentiometer (250 Ohm) adjust the transistor Base-Current (IBE).

The vibration can be enabled via a switch and the 1S Lipo is charged via the shown socket. On the left hand at the compartment I use the slot under the rubber cover for the switch und socket.

The motor is from an old servo. It should run at 3V. The imbalance is a collar ring with a screw. You can use an old Servoholder of a helicopter tail to fix the motor at case.

Hi all, after more as 300 views I like to ask you, if somebody also adding a vibration motor to the 12S?
Are they any questions or suggestions?

Best, Dirk

I found it very interesting, useful and instructive !!!

I am trying to find information on how to install a 3en1 multimodule or better 4en1 in the Devo12S, as you have a Devo 12S I see that it is a handyman, could you guide me? I can not find information.

Thanks in any case for this post ))

Thank you very much for your interest.

Sorry, but i can´t help you. The User 944storm is selling (see Marketplace) a 12S with multimod. May he can help you.

I would also like to see a 4in1 mod done to the 12s or alternately the 8s. I have a chip on the way and I'm hoping to see someone do it start to finish.

I found this Thread placing in a 4in1 modul at the Devo 12s:

Perfect !!! many thanks !!!!
