I'm looking for an Amplifier / Pulse which works on my Android phone, BLE enabled Vibration and Sound Alarm / Timer

Hello.

I’m not sure which place is the right one for my problem,so,please,excuse-me if I made a mistake writing here. Anyway,I want to try to ask. I’m trying to build a system to snore less and I’ve found this guide as starting point :

Anyway,I can’t do exactly the same. First of all because some time ago I’ve bought the jetson nano instead of the raspberry pi and I would like to save some money using that board. Luckily it seems that I can,at least,use the ReSpeaker USB Mic Array on the jetson nano.

The real problem is that they used the “neosensory-buzz”,that costs 800 dollars. I can’t afford this price. I’m looking for a similar device,that’s able to accomplish the same task of the neosensory-buzz,without upsetting the tutorial.

I need to replace the neosensory buzz with a similar but cheaper device that can be used with the other hardware components,like the jetson nano and the seeed respeaker (better if it is the usb version). I forgot to say that the Amplifier / Pulse that I’m looking for should work on my Android / Samsung note 3 phone, it should be controllable via ble. Let me know,thanks.

PS :

I found the “iLuv-SmartShaker-Vibration-Bluetooth-Notification” on amazon.

and this :

can u tell me if it can work in this scenario,very thanks.
