Evolution VIII

I have developed a device that can work with your original keyless entry/factory alarm or with the aftermarket alarm.


1. When you disarm your alarm or open your car with a remote, the device sends signal to your computers **power supply to initiate boot sequence, and delayed signal to your amplifier.


2. If you did not turn ignition or start the car within *15 minutes, it will cut the signal to your amplifier and computers **power supply to initiate shut-down sequence.

3. After you turn-on and then turn-off the ignition, it will wait *15 minutes and will first cut the signal to your amplifier and to the computers **power supply to initiate shut-down sequence.

4. If you use your remote to lock the car, it will immediately cut the signal to your amplifier and to computers **power supply to initiate shut-down sequence.

5. Optional 5VDC 6A power output to power 5V devices like USB2.0 hub and/or external CD/DVD ROM

The timer is adjustable from 1 to 15 minutes.
The amplifier signal delay is adjustable from 0 to 40 seconds.
Works with all power supplies which accepts +12v boot-up signal


The device is very easy to wire.

Four wires Input:
1. +12v Battery
2. +12v Ignition
3. +12v keyless/alarm signal pulse (lock/arm)
4. +12v keyless/alarm signal pulse (unlock/disarm)
4. Ground

One wire output:
1. +12VDC 10A signal to your power supply or startup/shutdown controller
2. +12VDC 1A signal to your amplifier.
3. Optional 5VDC 6A output to power devices like USB2.0 hub

Devise replaces your ignition wire output to your power supply or startup/shutdown controller.

Let me know the other ideas of functionality you may want for this device.

Estimated price is $50 USD and with optional 5VDC 6A power supply $60 USD


I tested this device in my car for nearly three month and it’s been very helpful to me.

Let me know if anybody interested to order.
