Hi all guys and happy to be part of the forum.
I'm new to the subject and to Theremino but, not electronic projects, even if not designed by me, with Arduino and Raspberry.
I am a Weather Station enthusiast, Drones and 3D printing….I've been wanting to try my hand at a new project for a seismometer for some time (for home use of course), I've seen many online but, the Theremino used as a sensor for earthquakes convinced me.
I have seen the many pages on https://www.theremino.com and for what I need from what I could understand is the MasterDIL https://www.theremino.com/technical/schematics plus the three-axis accelerometer https://www.theremino.com/hardware/inputs/accelerometers , among those proposed the LIS 344.
For the MasterDIL-V5 I saw that you buy already done, while the chip must be purchased for the accelerometer, ordered the pcb and soldered the components…so far everything ok no problem, I wire everything, I print the support in 3D and the hardware part is finished (if I have not made a mistake and lost a few pieces on the street or if geophones are also needed, becoming a little more professional, accurate but also expensive).
For the software part instead what to do…I seem to have understood that the MasterDIL has already installed the firmware so I shouldn't do anything, including any libraries (if with Theremino they are called that) for the accelerometer, then I download and install the Theremino Dolfrang acquirer on the PC https://www.theremino.com/downloads/geology at least I think so, the data acquired and saved I am going to read and process them with one of the many software for geology ma, I didn't understand what they are and where they download.
Other doubts are: it can work stand alone in the point where I place it (like following these tips https://comunitadigeologia.blogspot.com/2015/06/sismologia-dove-posizionare-lo-strumento.html) to then subsequently process the acquired data by connecting it to the PC? You are, the MasterDIL where it stores the data, has the slot for a microSD? A sort of DataLogger must be purchased?
Or it needs to be connected h24 to a PC with the Dolfrang software always active?
I apologize if I have dwelt but, I am interested in this seismometer and if someone has already tried to do it or can still help me because they know more than me I would be grateful.
Have a good evening

We apologize for the delay.20 May 2022 at 13:27 #23705
Good evening, I was losing hope sincerely….
In the meantime, thank you and let's see if anyone will be able to give me further information on the matter.22 May 2022 at 16:31 #23712
Ciao, everything you wrote is right.
Regarding the PC it always takes, our system is an IN-OUT for PC and therefore the PC is always needed.
On the other hand, we get considerably greater features than with Arduino.
If you really want a stand-alone system you will have to use Arduino, or you could use a mini PC or a Stick-PC
and then you can control it with Chrome Remote Desktop just as if you were on the spot.
Just be careful that there is real Windows (Windows 10 desktop and not RT or IOT or other such oddities)23 May 2022 at 18:28 #23715
I'm glad the long reading got me “understand” more or less the functioning and mechanics.
I would prefer to have a stand alone thing for the simple fact that I do not always have the pc on and to have a working seismometer only in some moments, it would invalidate its purpose.
That said, I love Arduino and its various and multiple projects but, if there is not already a done Sketch and related libraries, as geek as they are, I would not be able to help in case of problems, therefore I would opt for the mini pc solution with win10 and remote management, much more doable for my need.
The remaining doubts are still for the data acquisition and saving part that, I assume at this point they are saved directly in the PC (mini pc in my specific case), and the software with which I am going to read and process them if it can be downloaded from the sites indicated here https://comunitadigeologia.blogspot.com/ .
thanks for now

If you will be using a mini PC with Windows 10 o Windows 11 you can do everything very comfortably, with Windows folders and the usual methods used with a PC. You will be able to copy files, transfer files and even install programs and clean up, exactly as if you were in front of the mini PC. And you can do it via the network even if you are in another country and without even needing the MiniPC to be equipped with a keyboard and monitor. You will only have to set in the mini PC the option that makes it start automatically when you give it power.
Furthermore, the current mini PCs are quad core and have SSD memory (non Hard Disk) so they go very fast while consuming little (dai 2 to 6 watt a 5 volt) And our electronics consume a few millimeters (not more than 15 milliamps in total).
You can find Z85 MiniPCs with Windows 10 less than 150 euro, therefore little more than an Arduino + power supply + Box + Vari Shield required.
Then you will have to add our Module Theremino_Master and our Theremino_ADC24.
At this point you can easily use any kind of sensor, we have published documentation on everything, and if you can't we will help you.
And as for the geology programs you can ask Dolmetta about the site https://comunitadigeologia.blogspot.com

Ok I deepen everything then doing further research on the mini pc…
Thanks for the info and contacts
Hello Pierluigi24 May 2022 at 18:49 #23721
OK, I just add that ours are totally disinterested advice since we don't build or sell anything.
The modules of our system are manufactured by others and you can find them on eBay at the seller “maxtheremino”
