Hello,
I originally ordered my 1D Shake as the DIY kit with the acrylic enclosure. I was always planning on building a seismic vault (currently in process), using the USGS design as a guide. Initially, I wasn’t concerned with the Shake getting wet inside the vault, after all the vault is designed to keep it safe and dry so the acrylic enclosure not being waterproof was not a concern.
As time went on though, I started to become worried that I’d wake up one day to a flooded vault and decided that I wanted to put my Shake in a waterproof enclosure, just in case.
The outdoor enclosure that raspberryshake.org sells, looks nice but $340 is a bit steep (not saying it’s not worth that, just that it’s expensive). So I looked into making one myself, here is what I came up with:
I used an IP67 enclosure (PTK-18428-C) made by Bud Industries, as well as their IP67 rated vent (IPV-67101-B). Fortunately, Bud makes 3D models of their enclosures available, so I was able to use that to design an aluminum plate for the inside of the enclosure that matched up with the enclosure’s bosses. I used that plate to mount all the components to.
Admittedly, using the raspberryshake.org’s enclosure as inspiration, I also designed an aluminum plate that attached to the bottom outside of the enclosure to give me a place to put the leveling feet (I reused the ones that came with the acrylic enclosure but any screws would work in their place).
I’m using a PoE adapter for power and data to my Shake so I used an IP67 rated RJ45 feed-through cable gland made by L-com (CG-RJ) to get that into the enclosure.
To get everything to fit, I had to remove the PoE adapter’s case and use an existing hole in the PCB to mount it to the plate. As well as make modifications to the cables coming from the adapter.
Finally, I designed (again using the 3D model of the enclosure to use existing bosses) and 3D printed a holder for the geophone.
I’ve included all the relevant part numbers inline, I had the aluminum plates made by SendCutSend. If anyone wants the files to be able to order your own plates and/or to print the geophone holder, let me know (or stay tuned to adamslab.io as they will be posted there eventually).
All told the total cost (including shipping) for the enclosure was $96.88. Hope this is helpful to someone.
