Can a magnetic switch (the reed switch) be triggered on by using a tin can instead of magnet. I was wondering if i can use it to sense tin in my recycling project. please if possible give me other information on how to use this switch. (i am a mechanical engineer !!).My second question is can all capacitive sensor detects plastic or there is a particular type of it which does this and how much does a small capacitive sensor (which senses plastic) costs?
hard factor. look into on to yahoo and bing. this could actually help!
check nutrition facts for iron, juice is good for that kind of stuff which is also why they tell u to drinnk juice before donating blood, and they check your iron for that too. i know that green tea or any tea decreases the absorbtion of iron, and nuts are good for iron too my head does that too so drink juice and garbanzo beans are good for iron too, idk if i spelled that right the head spinning could also be from not drinking enough water or too much caffeine. esp. when u get up from sitting down
