    Oh good… must be a variable switched mode power supply then.

    When I plug my balance/bleed tube and have a good seal around the mouthpiece you can test for leaks in your regular case.

    Not likely, just a couple "wall wort" transformers from old electronic devices...

    As long as you are feeding the little controller with DC you should be fine.

    okay, like I said, just old transformers (DC output) from other items long gone...

    There are some motors that require a PWM signal to vary the speed they usually have electronics built-in to the motor for commentating and they have more than two wires. I think in your case the Amazon listing description is a little misleading. If it work your good.

    I know you guys are past this, but thought I should mention McMaster sells a self-fusing rubber electrical tape that one can make all sorts of gaskets and wraps with. No DIY workbench should be without at least one roll.
    McMaster-Carr

    Wrap a barbed hose fitting in it and make a type of stopper on one end.

    But you know what? Two fittings as shown in an earlier post is a much more elegant solution. I wish I knew someone with connections to a machinist who likes to make parts for his DIY friends. Let's see now, who do we know like that @Open Ocean Diver ?

    I see you all bought the Scuba Tools fitting. I am way too cheap for that. That’s the last piece that I have to complete: going to Home Depot and seeing what I can use to shove into my regulator. I figure between PVC pipe, maybe or maybe not baked in an oven, as well as a variety of sizes of bicycle innertube available to me, etc., I can figure out a way to create the seal on the second stage.

    But before I go and let my creative juices flow, anyone have any suggestions?

    And for @rhwestfall, I think your motor will do just fine, whether it’s designed for a motor controller or whether it would handle variable voltage. I don’t know which my motor is, and I can’t even express how little I care. The amount of time we will be running these motors is so vanishingly small, and the load we will be putting them under is so vanishingly small, it really doesn’t matter. At least, IMHO. Engineers who do this for a living might disagree, but their requirements are several orders of magnitude greater than what we are looking for. :)

    ETA: besides, when you’re buying things from eBay and your primary requirement is based on price, suitability of design was never part of the equation anyway. :)

    Ha ha there you go…. Who cares it’s only worth $11 just hook it up. Daaaar
    Home Depot I think they have glue guns, should work to seal the mouthpiece. :) cobble cobble
