Hi Chaps, Here's my simple to make Smoke generator. I used about 7cms of NiChrome wire connected by metal connecters with the plastic cut off, to heavier wire (like the ones on your 6-12volt motor) . I got a plastic box and computer fan and smoke fluid and the thingy that fits on the lid to let the smoke out, all from Maplins (Components section) quite cheap. Then drill a hole in the box each side about 10mm from the top, just big enough for the thick wires in a snug fit (no sealing required) Now take a piece of fibreglass tissue about 20cms long by 4cms wide and fold or roll it up to make the wick 4cms long and now wrap the NiChrome wire around the wick and position it so the wick touches the box bottom. Put in some smoke fluid about 1/4 inch deep in the bottom making sure the wick is well soaked. Test it by connecting it up to a 6volt 4amp SLA battery, it should start smoking as the hot wire burns the fluid on the wick. I experimented with a few drops of linseed oil and a few drops of diesel fuel mixed in and it smokes a treat. Put the fan at one end of the lid and mark and drill the bolt holes. You will need to drill three or four larger holes in the lid, directly under the fan blades to let the air into the box. Drill or cut a larger hole in the other end of the lid to take the pipe fitting which lets the air and smoke out up the funnel. Screw the box lid down and connect the red and black fan wires to a pack of 8 AA batteries (9.4volt tranny pack), connect the smoker wires any way round to the 6volt battery and you should get smoke pouring out the funnel pipe. Thats it. I'll put some piccies on of mine. Regards Geoff.
