Im trying to build my own air powered actuators for a robotic arm. But to control them ill need some solenoid valves of some sort. I don't know the exact pressure yet, but ill use around 50-100 psi. I keep searching and don't really see to many cheap ones. They can be reall cheap after all this is just an experiment all it needs to do is open and close pritty fast.

Strange question, but I have a small microwave craft kiln which is designed for a 600w microwave.
The instructions say, if using a higher power microwave to turn it down. I need to know which setting to put it on - I have in the following order :
low
defrost
medium low
medium
medium high
high

Does anyone know which setting would be nearest to 600w on an 800w microwave?

I can't contact the company as they are in Japan and I got the kiln second hand. Thanks in advance :-)
