reduced noise heating pads
Any one know of a way to reduce the noise given off unwrapping the heating pads? I am soon to be subject of randoms at a new killer job and I'm planning on QFing them with a full time carry around arrangement like I did at the job before the current one. My plan is to stay clean untill they have their first random and then after I have the routine down, develop my plan. Previously I had made a device that had four 9 volts bundled to give 18 v at approx 300ma lighting some 24v halogen bulbs, the bulbs were enclosed in a thin piece of aluminum that was used for the heatsink, and the small Iv bag (from a FOF who worked at a hospital) was used to contain the water and when properly heated I mixed in unclejohns pee pee. I had a switch that I could cut on when needed, and all the wiring was using epdm insulated (rubber multimeter lead) wire. I see that The QF arangement is possibly going to be less bulky and inheriently more reliable, due to no wire connections to corrode and/or break. I have a multitude of fabrication options available, soldering, metal working and thermal plastic forming, epoxy potting ect. I am dedicated to this purpose and I will post diagrams, photographs and pertinent information to help everyone. First off does any body have a method to quiet the rumpling wrapper sound and can these heat pads be removed from the wrapper and encased in something else that could be clandestinely opened to allow the air in to start the reaction.?????I am going to have to get some of them and do some experiments, and record the results, and make adjustments as required. I could possibly make a sealed container with the qf bottle sealed inside, and the quicklime or other media outside of it, or as desighn may necessitate the qf on the outside and the heat media on the inside. I have done this before, with the batteries, I just would like to make it simpler, and more reilable, and chemical heat seems to be the way to go. Is any one else up to the task?? If we work together we could make urine testing for pot pointless.
