Nice work John! My granddad had Parkinson's, and he'd have benefited from this a lot.

I was a bit surprised that a small priming pump could pull the thicker material through, but it doesn't seem to be struggling at all. I've been playing with one myself recently (looks identical in size to yours), as a way to turn one of those nasty vaping things into a miniature smoke machine (using a glycerine and water mixture -- not the weird toxic poison most folk use them for, I feel inclined to point out!).

You're making me think there are lots of cool things that all the makers and hackers out there could do with these small priming pumps. Maybe we should have a competition around putting these motors to other weird and wonderful uses?

Anyway, great work! Let me know if you're looking into building a Mk. II -- maybe we can help out with parts?

Brilliant solution to the problem.

While all the other suggestions are workable, the one you have works for most of the tube.

I'm guessing that any residual cream left in the tubes can be combined into another tube at some later date.

I agree that manufacturing the squeezing devices could be difficult, while this provides something anyone can duplicate.

Well done

Wow - another great project!! It works really well.

I think we could all have uses for such a machine - for example a low-cost touch-less soap dispenser that could work with any liquid soap,

by replacing the microswitch with a different sensor.

Great work John.

I am always impressed with your ability to find good solutions to problems.

Well done.

What a great idea, nice work :-) This could be so useful for a lot of people I think.

Rather than dropping the voltage down could you have used a higher voltage which was in spec for the pump and then controlled the speed with a PWM? You'd probably want to have a capacitor to help with peaks of current each time the PWM switched on.

Best Regards,

Ow, nice work.

Maybe it would also work with two rubber rolls, like a press?

Very, very slowly pull the tube in between the rolls for a few milimeters, and it pushes a tad of cream out?

It would require a person with good coordination to place the tube inbetween the rolls, but from then on, it could maybe be operated by mom if there would be an easy to press button that keeps the amount of movement at each button press low...

Hi [mention:f80b53cee57c44bc9d7c577d07d7c791:e9ed411860ed4f2ba0265705b8793d05],

Really nice and usefull gadget!! I love the idea, and I like your tender inspiration. I can also think in how usefull it is, not only for people with such a horrible disease (I also know people with it [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-aa0dc25e-eac5-470b-ac93-fa90a7193d44/contentimage_5F00_2.png:16:16]), but also for elderly people.

About the pump is supposed to work from 4VDC to 12VDC, so, can it work directly with the battery? And if the power source can feed too much current for the pump, what about using a PTC to protect the pump from overload condition, when the tube of cream is empty?

Really nice post John!!

Resgard,
