What was the solution to the problem? We are having trouble with our location dot still being gray. It is clearly collecting data but is not displaying the numbers below the graph under last observation . @shicks

<p class=”user-nicename”>@jamesbailey, I just noticed this post and have a quick answer to your first problem regarding the EnviroDIY/TippingBucketRainCounter library.</p>
In April 2021, I issued the v0.2.0: Add Anemometer Counting and Bug Fix release, which not only fixed a byte-order bug in the original release, but also expanded event c…[Read more]

@craig607 yes totally agree, spit balling or back of the envelope sketch 🙂
So great – you can see I’m asking the dumb questions, and if some one has to pick up the bottles every so-often, then can also switch out the power source batterys :).
I see now how the hardware fits in, and found the schematics…[Read more]

@neilh20 so the board here is called a MKS Base V1.4 if i remember correctly. It’s an old 3d printer board. There are a slough of options and which is used really doesn’t matter. They are all, like the mayfly, a modified arduino. Though these use the arduino mega as their main design.
I have the relay controlling the power to the board itself.…[Read more]

@craig607 great to see the stepper functionality and managing it with the GCODEs though I wasn’t clear what the Marlin board is, and how it gets activated. Is the relay the power switch ON, or a pull to ground input.
This probably says how basic my view is, looking at powering, the 4.2V is nice as it maps to a LiPo battery, though LiPo are 4.2V…[Read more]

@neilh20 For my sediment machines I use a high torque 920z Nema 17 motor and is rated for 3.36v and 2.1amps. It works very reliably. The one I prototyped is a 76oz Nema 17 which is rated for 4.2v and 1.5amps. I have a pancake motor as well but they are lower torque. Here is a reference to a number of steppers from the 3d printing side of things:…[Read more]

@craig607 fascinating, thankyou for the brainstorm.
Looking at the stepper motor power draw, seems like managing where that power draw comes from would be part of the design. For one source of steppers that give a range of V and A, there is a lot of choice https://www.adafruit.com/?q=stepper&sort=BestMatch
Happy to brainstorm that part if its useful.
Cdavis replied to the topic DIY auto sampler in the forum Infrastructure and Equipment 2 years, 7 months ago
@heather, I would consider that. I still need to figure out the details on implementation and code.
