Recessed Door Window Contacts Reed Security Alarm Switch (5) (reed switch recessed(5))
No external power supply, connect to wired alarm control panel GND and N.C ports directly!
Description :
These door contact sensors are great for residential and hobby card access systems, as well as a security burglar alarm system. The door position switches operate with an internal magnetic reed switch that closes when the opposing magnet comes within range of the door sensor.
Hence when the door opens beyond the range point the door position switch will toggle from a closed signal to an open signal.
When this happens the access control system or alarm system will sense the change in continuity and will know that the door or window has been opened. When the door or window shuts, the door sensor will notify your security system that the opening has been closed.
Material Shield: Anti-fire ABS
Connecting Mode: N.C.
Rated Current: 100mA
Rated Voltage: (VDC)100
Operating Distance: More than 15mm, Less than 25mm
Rated Power: 3W

Flexible Shaft Coupling OD18mmx25mm CNC Stepper Motor Coupler 5mm To 8mm (Flex coupler 5 to 8mm)
What's in the box?
Shaft misalignment can limit a machine’s performance, cause excessive vibration, high reaction loads, and accelerated wear, and often leads to premature equipment failure. Flexible Shaft Couplings can help prevent these issues by transmitting torque while compensating for parallel, angular, and axial misalignment between drive components. When installed correctly, flexible shaft couplings can also reduce vibration, minimize noise, and protect driveshaft components.
Specifications
- Type:Flexible Shaft Coupling
- Material: Aluminium
- Size: 5mm x 8mm.
- Outside Diameter: 19mm
- Length: 25mm.
- Colour: Silver
- Main dimensions: d1=5mm,d2=8mm,D=19mm,L=25mm
Features
1) The structure is simple,easy to install,buffer,damping,convenient to disconnect.
3) The flexible connection can absorb vibration, compensate radial, angular and axial misalignment.
5)Shaft coupler Often used to connect servo motor, stepper motor,encoder screw driving machine platform etc.

1 x USB sound adapter
Resources
In Raspbian, this device should show up in the audio control panel automagically (go to the Raspberry Pi menu, then Preferences, then Audio Device Settings, and select USB PnP Sound Device).
We recommend providing a good signal to the input, as it provides no gain/boost for passive mics.
Once you're up and running, record audio input on your Pi, in the terminal, by typing:arecord -D plughw:1 -f cd /tmp/recording.wav
