Update 2015-03-24: I added support for the PCB on the inside of the box. Please collect again! Might you be interested in the Hulda Clark science of health, than you definitely want to build yourself a Zapper. This thing is for a modified dual frequency zapper, that has a switch to choose between the 2 frequencies, after which the relevant leds will flash to indicate on which frequency you are zapping. Please LIKE before collecting Thomas www.3Daybreaker.blogspot.com This thing is the casing only. The featured picture is decoration only, please only print the separate files. Print both bottom and lid, which assemble with 6 screws. You have to build the zapper electronics yourself It does not matter if you make a PCB, or a spaghetti wire build, as long as you can fit all in the casing :-) I am still waiting for components, so I might change the design when my PCB is ready. The schematics are here: http://paradevices.com/schematic.html The upper big hole is for the frequency switch, the lower hole is for the power push-button. The 4 little holes are for 2x 2 leds, that are driven by another 555 circuit , to reflect either of the chosen frequency switch positions. The schematic for the 2 flashing leds is here, as "railroad crossing signal". You have to either build 2 of those circuits, or drive different leds depending on the switch... it's up to yoy :-) The 2 handholds must be connected through 2 banana sockets in the front of the casing. I only provide he box :-) Please LIKE before collecting Thomas www.3Daybreaker.blogspot.com
