kind of a goofy experiment, but really useful. i’ve had a lot of LM335Zs laying around for a while. my christmas present this year was a new Arduino Mega 2560 board that i’ve hardly had a chance to do anything with. using the lovely Space Tinkerer’s blog and the good ol’ TVOut library, i turned a thrift store bargain into a fancy CRT monitor that reports the ambient temperature on the work bench.
