Re: Temperature Task
Ohh. Well, in that case, I'd better tell them!
Thanks for the prompt answer, questionguy!

Re: Temperature Task
Warning: AcuRite thermometers suck. I stole the bimetallic strip off of this one, and it only curls/uncurls in presence of a candle/soldering iron. My measly 6v lantern battery had no chance of curling that thing up. (I know that one is particularly tempting; spend an additional $243 and you get FREE shipping...)
I don't know about other AcuRite models, but I'd stay on the safe side and look for the bimetallic strip from a meat thermometer. Much more responsive.

Re: Temperature Task
Just to clarify, the strip from the meat thermometers work fine with a six volt battery. Also, can you find a meat thermometer at any kitchen store or Sears?Primate wrote:Warning: AcuRite thermometers suck.

Re: Temperature Task
I think they're even sold at CVS. The one I used was actually stolen from my mom's kitchen drawer, so I can't attest to the reliability of any thermometers currently on the market. (But yes, mine works wonderfully with a 6v battery.)questionguy wrote:Just to clarify, the strip from the meat thermometers work fine with a six volt battery.

Just a heads up, though: I did have to saw through the needly bit to get the strip out.

Re: Temperature Task
Our team used a bimetallic coil from a thermometer with the needle still on it to complete a circuit. We were a little worried about the time it would take to cool enough, but we got with 3 secs of a minute at regionals.

Re: Temperature Task
Interestingly enough, the bimetallic strip is actually one of our most reliable transfers. Usually it's the sand timer and the balloon that are the issue.JTMess wrote:Our team used a bimetallic coil from a thermometer with the needle still on it to complete a circuit.

Haha, Ours too I like bimetallic strips now.Primate wrote:Interestingly enough, the bimetallic strip is actually one of our most reliable transfers.

It was suprising that the balloon chemical reaction proved to be the toughest task to get down so far for me.
But, I haven't built the Sand timer or final task yet so

Re: Temperature Task
For some reason, whenever I put the nichrome wire around the little end of the bimetallic coil, it doesn't work. I got the coil from an outdoor thermometer at Lowes and pulled it out with my hands. Can anyone tell me what I'm doing wrong. I'm using a six volt battery for electricity.

Re: Temperature Task
First of all, try running the current directly through a little piece of the strip (3 to 4 inches, just recurl it up). Also, the strips from meat thermometers are a million times easier to use--they don't require nearly as much juice to curl. My outdoor thermometer required a soldering iron to actually move...questionguy wrote:For some reason, whenever I put the nichrome wire around the little end of the bimetallic coil, it doesn't work.
