Dripper Cart - mechanical

[smc]

I was bored in class so I thought I would sketch a design I had been thinking about for 510 carts.

Essentially this mod could be done with metal tubing, metal rods, a tap and die kit, drill, washers, dropper and a flexy straw (just the flexy part).

The basic idea: The base of the cart would rotate around the top of the cart (micro sealed bearings). As you twist the base the inside base cap would move (plunge) toward the top of the cart. Inside the cart would be a flexy straw attached to a driper.

The hard part of this mod is to affix two guide and support beams inside the tube for the 'plunger' (or base cap of the cart). This could be done by inserting a washer that must be tapped into place. The washer would need to have at least 2 holes drilled into it, and then threads made within these holes. The base cap would also need holes for smoke.

Anyway, that's the basic idea. I doubt I will get time to attempt a fabrication as I am back in school. Just thought I would pass this along just in case someone has the tools and the time.

For now I am going to try the 'top cap' idea someone came up with, but rather then use mesh I am going to try using water wick (wet bulb lab wick)... essentially the same stuff they use for oil candles but for water/chemicals.

with all that machinery where are u gonna put the juice?

If you get one made, Ill buy it.

- There will be enough room for 2 drops. In reality, based off the rough sketch (I did not break out the calculus to figure it out) I would imagine around 12..15 drops. If done properly it would retain the same volume as the portion of the cart that holds the liquid. The only issue is the support/guide rods. They would need to be rigid enough not to allow the inner cap (plunger) to move with the outer shell... otherwise the plunger does nothing and the whole system fails. I could do a proof of concept using stuff from a hardware store, but a quality design would need to be done in CAD. If I get the time I will do a scaled model using card board to illustrate the idea.

I like mechanical systems, but was also looking into micro and nano diaphragm pumps. They use them often for drug delivery system in the medical field (embedded insulin system). I found some that were perfect, but I could not find a price anywhere. I imagine they are quite expensive. With a pump and the right nozzle you could eliminate the bridge all together.... assuming you get the flow right.
