Reminder: we’re limiting this forum topic to non-technical questions related to the production status and availability of EnviroDIY products like the Mayfly Data Logger or its accessories.

Please post other Mayfly-related discussions separately on the Mayfly forum. We’ll move off-topic replies posted here to their own threads to preserve the…[Read more]

My stations as described above have been working fine for 3 years in the field.  I’ve had a few components fail (12-5v buck converter, XBee daughter card, resistor divider) but otherwise very stable.

However, one Mayfly (0.5b) seems to be performing fine with 2 exceptions:

• the red LED3 is either solid ON or dim
• the ADC that records the 12v…

Thanks. The project perspective is often – initial qty and then what might be follow on qtys.  Of course project planning is only a what if, and no guarantee

In my experience, one of the challenges with building an electronics board, other than the world wide supply chain issues,  is that the base cost of engineering often means that at least 5…[Read more]

Hi Neil,

I would only need 5 at this stage.  I would connect it to my Yosemitech turbidity sensors and potentially Yosemitech pH sensors as well.

@James_NZ  – I’m curious, just wondering how many RS485’s stations are you looking at and your planning project timeline.

What sort of instruments/powering are you looking to connect to.

There is a forward looking discussion on issues here, though the timeline for anything being built, I’m guessing is really dependent on specific project…[Read more]

Thanks Shannon.  Please let me know as I will likely order a few of these and some mayfly 1.1’s.

Appreciate the hard work.

James

No estimate yet, I’m still working on the redesign and will then have to get them manufactured once we’ve fully tested them.

Hi Shannon,

Do you have any idea when the RS-485 half shields are likely to be in stock?

James

Hi Shannon,

Thank you once again for your thoughtful and thorough reply – as well as for your patience and understanding of my Mayfly ignorance for not having attended a workshop.

I greatly appreciate you sharing your time and knowledge.  Your reply above is quite helpful.

The board already has corrosion issues on the main chip- likely…[Read more]

DaveG, since you inherited a monitoring station from a previous owner, you didn’t get the full training we give station owners when we teach a workshop and/or install a station for them.  I would suggest looking through all of our EnviroDIY Monitoring Station Manual  since we thoroughly document all of the information about station assembly, i…[Read more]

For the solar connecter, I colour the socket and the jack in an acrylic orange so that there is a visual match. The LiIon battery in a cooler blue.   Of course have to be careful to only get the acrylic paint on the outside of the jack and not have leak inside. Its not perfect, but provides a little clue.

Suspect Mayfly1.1

The cable I was using also went bad and I’ve marked it as suspect – its a distinctive pink cable.  I’ve inspected the Mayfly USB c on Mayfly1.1 with an Eye Loupe, and it is hard to inspect but nothing jumps out, seems OK.

I did have a USB current monitor in the testing before hand, and the current had gone up to 1.2A while…[Read more]

Are you saying you’ve got a bad cable or a bad Mayfly?  Have you tried a different USB-C cable?  The pins in USB-C connectors and cables are extremely small and are easy to fail.  And when the pins in a cable’s connector get bent or damaged, we’ve seen them inflict damage on brand-new boards, so I’d suggest trying a new cable or two.

Matt, you are correct that it appears the solar panel was connected to the spare LipoBatt JST socket on the Mayfly, which causes the board to see those high levels during the day.  The voltage regulator on the Mayfly can theoretically be damaged if you put more than 6.5v into the board via the LipoBatt jack, so they should definitely fix that as…[Read more]

These were just deployed 3 days ago and have been doing this from the beginning.

I am curious, did this just start or when you look back on battery voltage has it been doing this foe a while ? TomG2
