Cdavis started the topic DIY auto sampler in the forum Infrastructure and Equipment 2 years, 6 months ago
During my lunch break today I managed to slap together a prototype auto sampler that could potentially complement the mayfly. It’s also pretty cheap. I borrowed a 3d printed peristaltic pump design that I have borrowed before for an automated sediment toxicity renewal system that I have built for our lab. It has been very reliable and I already…[Read more]

@lyh2o I wonder, assuming you have this in the office, if you could enable some debugging and post it.
The debugging most useful is
-DMS_ENVIRODIYPUBLISHER_DEBUG
so depending on how you build, but if platformIO it would be on a separate line
build_flags =
-DSDI12_EXTERNAL_PCINT
-DNEOSWSERIAL_EXTERNAL_PCINT…[Read more]

I’m also unable to delete sites (Server Error 500), and unable to delete sensors (no errors, but nothing gets deleted). I am going to report this via an issue at the Github site for the MMW data portal:

The dipswitches are mainly there to let people know their board is working during initial testing or desktop deployments. Anytime a board is deployed in the field as a “sleeping” station, power savings are important during the sleep period. So I put the dipswitches on the new versions of the Mayfly to allow people to deactivated the LEDs. Th…[Read more]

Thank you so much Shannon!
One very minor last question – for the DIP switch, that would be turning the USB DIP to ‘off’ for the purposes of LED operation, correct? The ‘Power’ DIP switch would remain ‘on’?
Thank you!

I decided to try to make a new site in order to try to work around the problem, but that hasn’t seemed to work either. I’m now getting 504 response codes. The data is still uploading to MMW but not publishing. I have to be missing something obvious, right? The new site is NTNWD in the same spot.

@shicks. I tested the converters you recommended and they appear to work as expected:
dropout voltage is 8 Volts and will support input voltage to 31.5 V (max on my bench PS).
No load draw is 3.64 mA at 12 V and 2.83 mA at 31.5 V.
A lower cost option is a three terminal non-isolated converter at $2.76 ea vs $12 for the PlusRoc.

Powering the Mayfly v1.0 and v1.1 from the solar jack only would not be recommended because the power input circuit was not designed to operate that way. The most electrically efficient way is to use the 12v-to-5v converter and connect it to the USB-C jack and then deactivate the USB interface circuitry with the dip switch as explained above. T…[Read more]

Shannon,
I ordered several boards in the 1.0 release in the fall as replacements for 0.5 boards that are currently in the field. Our setup for those involved using DIN rails to connect large marine cycle batteries so we could keep our terrestrial stations operational during the winter. So, we used the 12v regulator on the 0.5 board and it has…[Read more]
