The two heaters shown are enclosure heaters.
The first is a rail-mountable enclosure heater encased in plastic (about 3.5in x 3.0in x 1.5in) that can be mounted in a glass, plastic or wood cage to heat the air.
Next is a thin fiberglass/silicon heater 6in x 2in fused to an aluminum mounting plate. I will be mounting this in a wood box to heat the air so I can keep deli-cups with baby snakes in there.
The 3rd pic is little t-stat, around 3.5in x 1.5in x 1.0in and cost only $13. It is bi-metal, so not for precise control. However, it makes a great high-temp safety cutoff and does not require any power itself. I will put this inline with the enclosure heater, but will use a proportional controller to maintain the temps.
Fun stuff to play with.
