Nope.  I was surprised I could record that 2.6 in Montana.  I can do so when it's quiet here which isn't often.

Is that with your new instrument or is that still in construction?

The Moho has been finished for two weeks or so.  That event is with the new Moho running right next to the Guralp CMG-40T.

Cool!

Is it complicated and or expensive to build?

Angel is going to offer four different options to build the newer Moho Pro.  That makes it easer in that you don't need a 3d printer.  You should contact him.

It's a really fun project to build and it performs very close to a commercial seismometer such as the Guralps or Nanometrics Trillium 120.  Of course, you need a SBC and digitizer board.  Angel sells the digitizer boards too.

Hi Jonathan,

I will have the price for the four or five kit we will offer

1. just the boards

2. boards and printed parts

3. All of the parts needed

4. Assembled and tested

To any of the kits you will need some sort of digitizer and of course I recommend the MOHO ADC you will also need an hermetic enclosure.

Cheers and Happy New Year,

Angel

[Guy Tytgat]

Cool, thanks.  I'm gonna look into it.

You should do ok building it.  Especially since in all the time I've known you, not once did I ever see you solder your lip to your nose!
