I propose a simple diagram of a control device for dipped beam or running lights of a car. Drivers very often forget to turn on the low beam when leaving the parking lot, and when stopping and leaving, they forget to turn it off, which threatens to discharge battery... The device turns on the dipped beam automatically after 8-10 seconds. The circuit is available for repetition even for a novice radio amateur, contains few radio elements and is reliable in operation.
Consider the operation of the circuit:
When 12v power is supplied to terminal X1 from the ignition switch of the car, the voltage through the resistor goes to the capacitor, which begins to charge. When a certain voltage level is reached on it, after 8-10 seconds, the transistor opens and the relay is triggered. Its contacts are closed and power is supplied to the car circuit. The running lights can be connected directly to terminal X2. If not running lights, but only the dipped beam, then the X2 terminal is connected to the car dipped beam switch.
The circuit is assembled by surface mounting. After assembling and checking the functionality of the circuit, all radioelements are packed in a box or in several layers of electrical tape. The device is installed in the car in a place convenient for installation.
Details: we will replace the C3987 transistor with KT829A. It is advisable to take an electrolytic capacitor of smaller dimensions, even the larger its capacity, the longer the delay in switching on the relay, and, accordingly, the light. A relay for a contact current of at least 5A (it all depends on the power of the running lights) and a coil resistance of at least 120 ohms.
You can also connect a simple five-pin automotive relay.
Digital multichannel call recording systems "Forget-me-not" series are designed for recording, registering, archiving and documenting telephone conversations and audio signals (from microphones, radio stations, etc.).
The proposed systems allow you to meet all the necessary requirements for recording voice information with analog lines, IP lines, digital lines and E1 streamscoming to PBXs from different manufacturers.
The systems "Forget-me-not" are equipped with the Duty Unit (service "02") of the Central Internal Affairs Directorate and the District Internal Affairs Directorate of St. Russian authorities, large russian companies and holdings.
Software:
The recording system includes additional software modules
- VoIP Recorder - recording of telephone conversations in corporate IP telephony networks
- File Server is a backup archiving module. Archiving to external storage systems
- Transcriber - for creating text transcripts
- FaxReader - for decoding phonograms of fax messages registered in the system
- RemotePanel - for remote control of the system performance using a wall-mounted LCD panel or monitor, on which audio-visual signaling of the state of the recording channels is carried out
- EventLogMonitor - to notify technical and maintenance personnel about system and emergency events by email and SMS
- SMDRanalyzer - to connect to the CDR / SMDR charging ports of the PBX via RS-232 or Ethernet interfaces
- API is an open software interface for interfacing with various external information systems (CRM, GIS, etc.)

I propose a simple diagram of the control device for dipped beam or running lights of a car. Due to the new rules road traffic you need to drive with low beam or with running lights.
