(*)*(*)*(*)*(*)*(*) (*) (*) (*) Crimson Box (*) (*) Plans (*) (*) (*) (*)*(*)*(*)*(*)*(*) The Crimson Box is very simple device that will allow you to put someone on hold or make your fone busy with a large amount of ease. You flip a switch and the person can't hear you talking. Flip it back and everything is peachy. MATERIALS: >-:->> 100 ohm or less resistor >-:->> SPDT toggle switch, On-Off >-:->> Solder and soldering iron >-:->> 3 feet of good wire >-:->> Wire cutters CONSTRUCTION & SCHEMATIC First I will give you the schematic and then I will explain what the hell is going on. -----------black wire on line--------- --------+ red wire on line +------ --------:--+/\/\/-green wire---:------ --------:--:-yellow wire-------:------ : : : +--:------+ : +----+ : +----------+ : : : 1 2 3 Ok. The '/\/\/' is the resistor. And '1 2 3' is the switch where the numbers are the poles on the switch. Notice you leave the black and yellow wires alone. You DO NOT cut them! Strip the red and green wires so you've got about an inch of bare wire. Solder some of the extra wire and follow the schematic. You should have the resistor on the green wire with an extra piece of wire coming from one leg of it. The other leg goes to the other end of the green wire. You should solder the green wire to the left pole of the switch and the red to the middle and the other end of the red to the right pole. Now, lift up the fone. If all you get is an annoying buzz then throw the switch and you should get a dial tone. If not, don't worry and just follow the instructions and schematic again.
