Hey all, looking for ideas on small/inexpensive Leap Day Potluck door prizes that me and the misses can make quick and easy by friday. Should be green/environmentally conscious ideas, alternative lifestyles related, using recycled/reused/scavenged materials if possible. Also, one other request is that we need to come up with a prize for a male (best costume, and best dish) to go along with the female prize which is going to be a hand drawn menstrual calendar for the female winner. Thanks!
Interesting. I never have heard of this before, and cant find anything online. Maybe he didnt want the penny, and didnt want to litter. lol
carbon monoxide sits low, it only rises as the room fills. the two burners with the ventalation you have should be sufficiant to prevent build up. if it concerns you go buy a carbon monoxide detector and install it about six inches below bed height, just to be safe. a better heat option for a trailer would be a ceramic heater. they use almost no power, heat small spaces very well, and are very safe
This will sound like a slippery answer, but it all depends on what frequencies of EMF you want to detect. EMF covers everything from Extreme Low Frequency (ELF, or the radio used for submerged submarines), through normal AM and FM radio, up through infrared, visible light, ultraviolet, X-ray and Gamma ray. Visible light detectors are dirt cheap - you have two of them in your head! Infrared is easy - we feel it as heat. A radio detector is another name for a receiver. These can get quite complex and expensive, depending on the frequency. I built an AM receiver using just 50 feet of stretched out wire, one diode and a button earphone. Cell phone frequency detectors will be expensive, however. Maybe you could start doing Google searches to narrow down exactly what you want to do and learn how to do it. There are *a lot* of ready-made schematiccs for most things you can think of. The $5 limit will be a challenge, but who knows?
