Feng Se from Aofeisi Quantum Bit Report | Public Account QbitAI
In the dead of night, when your neighbors are fighting, partying, or when children are crying and keeping you awake, how do you deal with it?
Do you knock on the door? Wear earplugs? Quietly endure until you develop neurosis?
A guy abroad was driven to a migraine by the noise from upstairs neighbors, so he created a “weapon” to retaliate.
This “weapon” is attached to the ceiling, and when the upstairs starts to “act up”, the guy gives the command, and the “weapon” begins to “pound” the ceiling.
Upon hearing it, the neighbors will immediately stop disturbing the peace, or even start emailing the landlord…
Connecting Home Assistant via MQTT Protocol
Of course, it can also be attached to the wall to “strike back” against neighbors on either side.
This “weapon” is called TallyWhacker, a smart home device.
The guy developed it using Arduino with an ESP8266 (a microcontroller with WiFi capability), connected the ESP8266 to WiFi, and communicated with Google Assistant (Google Assistant) to achieve voice activation functionality.
The ESP8266 can be bought for just over ten yuan on Taobao (Arduino programming code can be found at the end of the article).
It requires MQTT protocol configuration (an IoT message transfer protocol based on the publisher/subscriber model) to connect to Home Assistant for control, turning it into a smart home device.
Home Assistant is an open-source smart home system based on Python, introducing Google Assistant starting from version 0.56.
By using Home Assistant cloud services, you can connect the instance of Home Assistant to Google Assistant.
This instance appears on Google Home, and finally, you can use voice commands to turn the TallyWhacker on/off.
Using ESPHome, you can also connect the ESP8266 microcontroller to Home Assistant, but the configuration process seems a bit troublesome, so it was not adopted.
Once all operations are complete, with a command of “Hey Google, turn on TallyWhacker”, the white lever moves the switch, and a black arm connected to a DC servo (RC servo) starts swinging rapidly, making noise.
The duration of the noise varies randomly between 5-30 seconds. When the neighbors stop making noise, you can also stop it.
A relay is inserted above, which drives the motor by supplying power.
Of course, the guy also made a 3D printed shell for it.
Foreign Version of the “Tremor Device”?
Perhaps upon seeing it for the first time, you might think: isn’t this just the domestic “tremor device”?
The domestic “tremor device” is indeed very loud, with “excellent results”. It usually has a vibration motor inside, utilizing the principle of electromagnetic repulsion, using electricity to create magnetism that pushes the internal iron block, and so on.
After starting the motor, it causes the floor above to vibrate at high frequency, resonating with furniture and other items on the ground, leading the upstairs neighbors to hear noise similar to that of a hammer drill, while the sound you hear in your own home is very low.
However, using this thing could very likely violate the “Public Security Administration Punishment Law of the People’s Republic of China”, so be cautious!
The DIY version made by the guy, on the other hand, is much quieter, to the extent that some are curious if the upstairs neighbors really heard the noise it produced. The guy replied: No.
However, many people expressed that this invention is quite good, as there has never been a “tremor device” like this in their market!
So some are willing to be the first to support this product on Kickstarter crowdfunding.
To address the issue of low noise, the guy is also considering adding a couple of larger vibration motors on top.
He can also improve the shell to enhance the resonance effect.
