mist maker
Our shops are currently full of halloween stuff, amongst which is a plastic
cauldron of cold water that has mist cascading out of it, they cost £35+ without the cauldron. Anyone got a schematic for one ? from what I can find so far, they have a small ceramic disk which vibrates ultrasonically and creates the mist. I am considering a piezo sounder fed with 40KHz @ 9volts say, with the disk just below the water surface ? what do you reckon ? -- Pete Cross |

Cost $30 - $40 USD , then feed the output to your Halloween setup. H. R. (Bob) Hofmann |
