Hi. First of all sorry for my English.
I would like to show you an alternative drip system. I am a veterinarian and I have an alternative way. Use a medical drip with two holes for 2 wires and glue.

Price of the drip 0.46 €
10 minutes
wow... look like a mess! hahaha :)
I was thinking about a medical drip system, but can consumer buy them somewhere?
For the rest, it seems to be working very nicely. I guess you can ajust the drip speed?
Nice hack! Is that a roller clamp? A few of us have been wondering about those, how is it working for you? What kind of drip speed can you get before the drip turns into a stream? What kind of valve is that? Sorry for all the questions, but I am really curious about what you have got there.
I send a video to show the drip speed. It is very easy to change the speed and the drop size it is always the same (20 drops 1 ml). I know that it is a mess i promise to make a nicer one next week jeje.

see the video at 720p to see the drops
GREAT VIDEO! I love it! That roller clamp looks perfect for Peachy! And the drops are always .05ml? How do you know that?
Awesome work ser10gonzalez, I love your solution for the saltwater/upper reservoir. I might do that too :p Is that a special bottle? Is it just a regular bottle a hole in the bottom?
Do you have access to very large syringes? Perhaps you could run the hose through the syringe as the Peachy does now. If so, you could contain the entire assembly within a syringe, and perhaps you would not need glue!
Really impressed, please keep us updated Doctor Gonzalez!
In medicine, drips always drip the same size of drop (strange sentence) you need to know the amount of chemicals you put inside someone. In normal drips (macro drips) 20 drops are 1 ml, in pediatric drips (also known as micro drips) 60 drops are 1 ml

My upper reservoir it is just a saline serum bottle (with opened bottom) because it has rubber an you can puncture the tube quite easy. But anything (like a plastic bottle with opened bottom and a rubber cap) should be OK.
I cant understand the thing with the syringe, but this method it is very simple, if you want i can make you a diagram. I put a lot of silicone because it should be hermetic (airproof) if you want to control the speed with the roller clamp.
I am suppose to be in the second tier but I have no mail yet. If I manage to have a printer I will tell you if it works right
Seriously working VERY nicely.
I'll take a look to find Medical supplier in Canada.
It should be easy, in any hospital, clinic or veterinarian clinic should have many of them. If you send me my printer I'll send you a dozen :p

I hope this terrible drawing helps explain what I am trying to say. Basically put your valve into a syringe. The hose and wires go through the black part of the syringe and the other hose goes out the bottom, snug fit.

Yes that should work but you need to put glue in both parts because it should be hermetic I think that your system it is more complicated. Mine yo just have to make 2 holes and put 2 wires, if you want i may make a video.
And yes, this is the kind of thing...

That is it

Glue are blue circles. I made the holes with a needle and a lighter
You are absolutely right, my design is much more complicated. I just don't like sealants, I do not trust them. I prefer threaded with a gasket, but I digress.
Great drawing! When I get my hands on an IV I am absolutely going to try this.
I did find a lab supply, however, and got some pipettes and burettes today. I will report back on them when I can.
Nice one! My fiancé should be able to help as she works in the hospital.
:)
For what its worth here is one of my early dippers.
It has 2 wires very close together that are both struck by each drip at the same timeThe drip falls directly between them
connecting them very briefly.
I found this dripper worked great when it worked but ...
1. It was very sensitive to being perfectly vertical
2. Every once in a while water would actually bead between the to wires leaving them connected.
3. It was tuff to get a good seal that looked good and was reliable.
4. I couldn't adjust the drip size
5. The wires corroded very quickly.

have we considered using a standard iv admin set for drip regulation? in bulk (50 pack) they cost around $0.9-1 each and incorporate the tubing, drip reservoir, roller valve (for setting speed of drops)... they also have several standards for drop size, 10, 15, 20, or 60 drops /ml.... the 60 drops/ml would have an extremely high resolution .... something like this
Quick question: Are we using salt water because the resin wont float on top of normal tap water(density reasons) or are we using it exclusively for its conductive properties? And have we tried using a IR led and phototransistor to count drops? (like a Slot sensor)
You'll notice in an early post of this linked thread that fresh water floats on top of resin... So yes, the salt is required for the resin to float.
