Good first attempt. Some refinement would make it more accurate and durable. A hall effect sensor would eliminate bounce conditions and false positives, and coating all the water facing surface with a hydrophobic coating will ensure ALL the water is counted and not left as droplets in the funnel or on the paddles. Otherwise, a good prototype and a great jumping off point for new users. Thanks for sharing.

@MatSmithLondon 2 месяца назад

Can you share with us a product that can be used for hydrophobic coating? (Bounce can be eliminated with code / timing... I note it didn't seem an issue here though. Do you think that might change with long term use?)

@Winnetou17 2 месяца назад

@@MatSmithLondon Regarding bounce - we mostly seen "good" cases here. For example, if the rainfall is severe, or maybe if the wind is very high, I can imagine the water coming in weird ways down and then the ... balancer thing starts to tip, if the water it holds isn't static, it can "evacuate" faster / earlier and the coming water from above might come with force, and the tip from one side to another might not finish before it tips back again.

@veritanuda 2 месяца назад

@@MatSmithLondon Well, something like Rain-X would do, though there are many on the market. The problem with read switches is less about 'bounce' as such, but more because it is a spark contact that can have variable effects. That does not make them very reliable for long term. A hall effect sensor has no moving part and as such should be more reliable long term.

Chris, I can’t thank you enough for this presentation and sharing all the resources freely. As an academic who is working on hydroclimatic modelling, I cannot stress enough how important this seemingly rudimentary observation is for a robust understanding of our environment. After watching your other RPi Pico based weather monitoring presentations, I was inspired enough to try to build a soil moisture observation station for my study field myself, instead of buying them off the market. I now not only have a better physical understanding of how my data is collected, but I was able to control the manner in which it was collected too. To top it off, with the same funds, instead of being able to buy 3 stations, I will be able to install 35 stations! To whatever degree you can, kindly keep up your good work. And most importantly, thank you for your contribution. P.S.: I wish I could contribute a larger sum, but perhaps one day :)

This is a very interesting project, but i prefer to measure rainfall by checking the expression on the face of my neighbour's cat. If whiskers looks annoyed, it's 10-20 mm over three hours. if he's in a really bad mood, it's at least 40 mm over five hours, and if he looks like he's given up all hope in life, it's 50 + mm and it's been raining for days. Athough I may try this project myself, if I get a 3D printer. 😄

Just finished your video, I have a suggestion for an upgrade: I noticed that there was water that was beaded up and sticking on the funnel sides. My suggestion is to coach your funnel with a hydrophobic coating of some type....maybe some of the stuff you put on windshields? I use something called Rain-X here in the US on my windshield. I thought of that when I first saw your funnel, then when you showed us video in the with beads on it, I knew I had to speak up. This could have changed the amount that you received.... Overall, another excellent video....hope you have an excellent week!!

@jfan4reva 2 месяца назад

I saw a commercial version of this 20+ years ago, and thought the double tipping bucket design was very clever, because unlike the vast majority of rain gauges at the time, you didn't need to empty it. It was self-emptying! This was long before 3d printing became popular, so all of the parts were injection molded, but the design stuck in my head. Now, thanks to 3d printing, anyone can have one without having to spend $400+ dollars for a commercial version, AND if you so desire, you can display the rain amount in any measurement system you like (inches per hour, mm per hour, liters per hour, etc, etc, etc.) Although you'll have to do the math yourself! (How many inches in 10 centimeters? - Oh yeah - about 4, more or less. How many tips in a liter? So, tips per liter divided by inches per decimeter - (the metric measure no on talks about ) Gives (brain function throttled to prevent overheating) ....

Great to see this in so much detail with a lovely clear delivery. As my commercial weather station has failed again, I think it's time to have a go...

@gary-williams 2 месяца назад

That is such a clever mechanism. One nitpick with your code, instead of having a "while" inside a "while", the outermost "while" is effectively functioning as an "if", so it should be changed to an "if" to improve code readability.

Love the 3D printed rain gauge. There is another type that funnels water through a small and precise hole that forms drops. The drops are counted and the volume is known. For accuracy the sides need to be smooth and from a material that repelles water very well. You need all water to flow and not stick on the funnel sides.

@ccroy2001 2 месяца назад

This is amazing, where I work we have equipment that makes rain for IP (Ingress Protection) rating of products. We got a new, larger drip box and we were having trouble verifying the rainfall rate settings. With plastic sheeting and a large bucket we essentially made your funnel except it was 1 meter sq. I was the computer measuring the water with a calibrated beaker after 10 minutes of collection and we were well within tolerance. It took us days to come up with the method so I am very impressed by your design and resourcefulness.

Very nice design and implementation. You could possibly calibrate your rain gauge with a simple glass tube rain gauge ( I think that they are quite cheap).
