I have large compost piles that I use to process garden and kitchen waste. The piles can be controlled by monitoring temperature and adding green material, water and turning the pile. I shoot for 120 degrees or more to kill pathogens and seeds. More communities are turning to composting for recycling organic waste, so it seems to me, there should be a market for wireless temperature/humidity sensors for managing piles. For the welder helmet display, a voltage and amperage bar graph would be the primary information. Although, I suspect any good operator would not need the display. I also don't know if I would be able to watch the puddle and display at the same time. I'll have to test this. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Beautiful is writing same markup.
