I was wondering if you guys know any electrical appliances that really radiates heat source? this is for my class group project. The goal is to have a robot w/ temperature sensor to navigate based on temperature and find the hottest spot.
But the problem is, we aren't allowed to use real thing - fire.
Right now what we can think of is a electric portable heater, but somehow that doesn't radiate far enough, it's like 10 inches from the heater, we tried hair dryer, it is blowing really far, around 3 feet,but it is only blowing in one direction, it's not really radiating.
We need something that radiates at least 3 feet long.
