Infrared-RF 433-Bluetooth Arduino Remote
Control Any Circuit With a TV Remote (and an Arduino)
I think the best way to describe the pressure is by looking at the picture above where it shows the water spraying up... I am happy with the design and it works well, but if I were making it again, I would use the pens.
What kind of pressure do you get out of each of the 25 bottle sprayers?
Magnetic Stir Plate
I agree, that's exactly what I ordered. You can get a pack of different sizes for around $9 shipped. As soon as they arrive, I will update the pictures.
For the test, I took a small bolt and put some shrink tub around it. This worked for a test run. Looking back, it would have been better to take two bolts and put the head end together and shrink wrap it. That would have created a nice pivot point. The one I made clanked around a little bit. The best thing to use is an actual stir bar. You can get them on Amazon.
PTFE (Teflon) coated magnetic stir bars are the bees knees. They have low friction and don't react with that you're mixing. They add no flavors to the yeast culture and do not affect it. Super awesome for this (or any, really) application. - Jobar007
