HOW TO BUILD AND USE A DIVERTER BOX. Designed and Written by Lord Zartan PARTS LIST: 2 SPDT Miniature PC RELAY (about 9v, 500 ohm) 2 SPDT Miniature PC RELAY (about 5v,250 - 500 ohm) SPDT Miniature Switch 2200 or so MFD electrolytic capacitor 4 meg Pot resistor .01 uF capacitor 555 timer chip 2 diodes (1N914) 10 K resistor 2 4.7K resistor 9 volt battery -w- clip Pc Board 4 alligator clips some kind of a box (small) some 22 or 30 gauge wire to work with. If you don't know how to put together a project by looking at a schematic, then isn't the project to start with. I would ask someone with some electronics knowledge to give you a helping hand. This has to be put together on a pc-board. Enough talk, now the schematic: ��Ŀ NOTE * Print in Compressed Mode or Display in 25 x 50 ���Ĵ��Ŀ � �C �� � ڳo �5V � ��i � +9V � �l �� � �Ĵ���� ^ � � ���� ��������������������������Ŀ � �NC��o������Ŀ � � � � � � � � �Ĵ � � � � � � �o���Ŀ � � / � 8 4 � � � - � � 4000K� \ � �����������Ŀ � � � ��o � � �>/ � � � � 1N914 � � ��Ŀ � � ��Ŀ (4 MEG) \ � ���� ��� ����3�������������>��������Ĵ��Ŀ � � ���ĴC�Ŀ Pot � � �� � � � � 1� � �C �� � � � �o �� �����ij��� ���� ��� ��۳ / N� �ڳo � � � � ڳi �9V � ������7� � � ۳ 10K�\ 9^ ���i �5V � �I ___ Sign for Diode ^ I ---o --o Sign For SPDT or SPDT for Relay - ---o *Note: Add; well lets say some asshole you gave the diverter number to is Allways on it, just make sure you don't give the third line. The ADD line as its called when called with disconect and reset The 555 so you can call and use the diverter. OPERATION --------------- When line 1# is called it triggers the 555 to charge the 5v relay's. For the time specified by the 2200MFD & the 4 meg resistor. Then poof both lines are now connected and you dial out. Now the A.D.D. works by Reducing the resistence thus triggering the 555 to resest when someone calls Line #3. Whew! Well, the schematic explains almost everything. It would be helpful to you if you used one color for the line #1 clips and another for the line #2 clips and line #3. It will work even if you get the ring & tip mixed up, but you must get all of the clips on the right line. But, to be safe, you could put tags on each clip labeling it RING #1, RING #2, RING #3. USE --------- Installation. Find one of those green posts that are about 3 feet high. They are everywhere. Get a socket wrench to open it up. There will be (a) row(s) of paired up posts. Each pair of posts represents a line. YOU *MUST* KNOW THE NUMBER OF LINE #1. Sometimes the number is tagged on to the pair of wires leading up to the posts, if so pick these posts as your line #1. Then you can pick any other set of posts for line #2. Now to the good part. Use of the the final product. When you call up line one from your house you will get a dial tone almost immediately. Using DTMF you can dial anywhere that the person who owns line #2 has service to. Which means you can direct dial alliance, Australia, and your favorite BBS for FREE. The Telco. will undoubtably discover the device after 2 days, so post the number on your favorite boards so you can abuse it while it is in service. With a 2200 uF capacitor and a 1 meg resistor you will get a 50 minute call before it disconnects you. By lowering the value of the resistor and capacitor you can change the time to your taste. So don't dial a wrong number, because you will have to wait 50 minutes until it resets again or use the ADD to reset the box. Here is the formula for time: 2*R1 C1 C1 is in microfarads ---- * ---- R1 is in Kohms 100 10 See schematic for location of R1 and C1. ----------- = Minutes 60 The time produced by this formula is only approximate. Well, that is one of the more complicated boxes to build. But it is very useful and will pay for itself with its first use. It would be wise to remove it before the Telco. finds it so you won't have to make another, or install it on a line that belongs to a family that is on vacation (GOOD IDEA) Written By Lord Zartan of NPA
