Simple bicycle alarm

The switch has been installed within the handlebar's tap. A battery holder has been created from a repurposed flashlight. As demonstrated in the video in step 1, the siren has been placed inside the left end-bar grip, with the wires running beneath the tape and inside the tube where they connect to the circuit.

The circuit described involves a switch, battery holder, siren, and wiring that integrates seamlessly into the handlebar of a bicycle or similar vehicle. The switch, mounted conveniently within the handlebar, allows for easy access and operation. The use of an old flashlight as a battery holder is a practical approach to recycling components while providing a secure housing for the power source.

The siren is strategically located in the left end-bar grip, enhancing the aesthetic and functional integration of the device. This positioning not only minimizes the visibility of wiring but also ensures that the siren is effectively placed for audible output. The wires are carefully routed beneath the tape and through the handlebar tube, maintaining a clean appearance and protecting the connections from potential damage.

This setup likely operates on a low-voltage DC circuit, with the battery providing the necessary power to activate the siren when the switch is engaged. The choice of components suggests an emphasis on simplicity and efficiency, making it suitable for DIY electronics enthusiasts looking to enhance their bicycle with auditory signaling capabilities. Proper insulation and secure connections are essential to ensure reliable operation and prevent any short circuits, especially given the potential exposure to environmental elements.The switch has been mounted inside the tap of the handlebar. I`ve make the battery holder out of an old flashlight. As you can see in the video in step 1, i`ve put the sireen inside the left end-bar grip and the wires pass under the tape and inside the tube where it meets the circuit. 🔗 External reference
