Bipes...or would this work...
 

yeah it should work for 1$ it is worth a shot.

yeeahh that's what i was thinking...buttt

would the bipes still work better do you think? if this thing says it can time 20% plus or minus....what can bipes do in comparrison...

not bad for a dollar.

bipes can zero you out totally. that think can pull 20% ugh that would only be 4 degrees at 20 btdc, nah skip that you run 30 or so on top if i believe it is not conservative enough for your needs.
