How to turn on the computer by phone?Introduction
Earlier I already described one convenient tool, considerably helping me with work. So left that that review resembled test programs for iPhone more, than the full analysis of the service. In brief I will remind that the main idea of that review was in showing how to get access on the Internet to my computer at work which is in a local network of establishment and working “ outside “ through a proxy. Coped with this logmein. And so keep to the point :).
to Make so that I could turn on remotely the personal computer, at the same time existence in automatic loading of Logmein programs, will automatically make my computer available “ from out of “.
Search of the decision
having Persistently googled this subject, it seemed that decisions - weight, take - I do not want. One of such “ pseudo decisions “ there was WakeOnLan (WOL). Everything is very simple. The computer joins on command, coming from out of to the modem and if at the same time in Bios everything is built adequately up (Wake On Modem is included), then the computer turns on. This way would be good if my provider was NE YuTK as for giving of command for the modem, it is necessary to know its external WHITE ip. I naturally have no such pleasure therefore this method disappeared, even without having passed tests :).
Still there were similar methods if to podlyuchit the mobile phone to com - port, and to turn on the computer on the coming call as dial - signal up (but to find phone with such interface it was an excessive task). And some more options...
Idea of a device
to Turn on the computer on the entering call on phone, without connection it to additional “ to " interfaces; and only to use the native sockets going on a metrinka. For “ " switch; to use a zvonkovy chain of phone, i.e. usual wires from the loudspeaker. Thus we will suit any calling unnecessary phone without additional date - cables.
What it would be desirable to provide in it:
1) besides inclusion to have a possibility of remote Reset`a
2) besides item 1 to have a possibility of remote switching off (and on a case of global lag of the computer, - “ emergency switching off “) Personal computer.
3) though least protection against a wrong / false call
4) not to work on SMS
Development of a device
In brief algorithm of operation of the device looks as follows:
1. We check whether the previous call ended.
2. We expect a new call.
3. After coming of a call we check, it is included or switched off the
4 computer (RS). If RS is switched off, we set temporary gate of 8 - 13 seconds and we check whether duration of a call to this time interval got. If did not get - the call is considered false, then we come back to point 1.
5. Duration of a call got to the set temporary gate - the call is interpreted as a signal of inclusion of RS. On 1 sec. of the K2 relay closes contacts of inclusion of PC “ PW - SW “.
6. In 2 sec. it is checked whether RS joined. If yes - we come back to point 1.
7. If is not present - we repeat short circuit of contacts of inclusion of PC “ PW - SW “ already on 3 sec.
8. Irrespective of RS joined or not - we come back to point 1.
9. If at implementation of point 3 it became clear that RS is included - we set temporary gate 17 - 23 seconds and we check whether duration of a call to this time interval got. If duration appeared less than 17 sec. - the call is considered false, then we come back to point 1. If duration is ringing more than 30 sec. - the call is interpreted as a signal of switching off of RS (see point 12).
10. Duration of a call got to the set temporary gate - the call is interpreted as a signal of dumping of RS. On 1 sec. of the K1 relay closes contacts of dumping of PC “ RESET “. RS reboots.
11. We come back to point 1.
12. Duration of a call exceeded 30 sec. - the call is interpreted as a signal of switching off of RS.
13. On 1 sec. of the K2 relay closes contacts of inclusion of PC “ PW - SW “.
14. In 1,5 min. it is checked whether RS was switched off. If yes - we come back to point 1.
15. If is not present - we carry out dumping of RS, on 1 sec. closing contacts of the K1 relay - dumping of PC “ RESET “. We maintain a pause 3 - 5 sec.
16. We turn on the K2 relay contacts of inclusion of PC " become isolated; PW - SW “.
17. We check, RS was switched off. If yes - we come back to point 1.
18. If is not present, continuing to hold the K2 relay in the closed state, we come back to point 17. Process repeats until RS is not switched off.

we Call the :)
As you can see, everything miraculously works;)
Iskhodiniki and pictures in good permission it is amusing
P. of Page
here that the device with similar functions costs 13k rubles. Why to pay much when it can be made most in 100!!!! time is cheaper than =)
And still, as council: best of all sim cards of Beeline since their call waiting time (i.e. what is the time the subscriber can be called until they on the switchboard tear off a call) makes ~ 1 minute 20 seconds will be suitable for similar devices. For comparison on Tele2 ~ 20 sec., on MTS ~ 40 sec.
