View all threadsEttus B2x0 enclosure group buy/machining interest?
I've been doing a little research on cases for the Ettus B2x0 series, and wanted to talk to the group about interest in some sort of group buy, or at least group machining. I have one of the Takachi enclosures, which is a perfect fit for the board, and the price is about 21 USD in the volumes that we're likely to do. That includes silver finish, and aluminum endplates (unmachined). They have the same enclosure with ABS plastic endplates, though, for about 8 USD. I don't think that the plastic endplates will work very well, though.
I have a local friend who owns/runs a mid-sized machine shop, and will be taking him my enclosure to see what the cost to CNC machine the aluminum end plates. I'll have him look at both machining Takachi-supplied end plates (so, the 21 USD enclosure), as well as making end plates from blank aluminum stock (so, using the 8 USD enclosure). He can also do laser engraving, so will get pricing on labeling the end plates as well.
The absolute easiest thing for me/him to do would be to just machine the end plates from stock, and you get your own enclosure from Takachi. But, while the Takachi company was extremely pleasant to work with, there's still the back and forth across time zones, etc., and I'm not sure about the costs of the different options yet to say which would be the absolute cheapest.
How many people would be interested in a bulk buy/machining? How much would you be willing to spend for a complete enclosure, with CNC-machines end plates for either the B200 or B210? Both of those numbers will help me when I talk to my machinist.
Also, Ettus folks, if there's any interest in me getting you in contact with my machinist for a possible "official enclosure", please contact me offline, and I'm happy to put you in touch. I have a day job, and would rather spend my free time playing with my B200 than coordinating shipping, etc.. :)
Thanks!

It'd be great if the holes for the RX/TX mounts could take rubber seals or
similar to keeping drops of water running down antennas out. This would open up
possibilities for using the board outdoors. I have this with my home-brew
solution.
Furthermore, a case that is volumetrically no larger than it needs to be would
be appreciated, helping those of us that primarily use their B2x0 outdoors or
inside other objects/installations.
In any case (no pun intended), count me in for up to EUR40; my home-brew
enclosure, made from a large plastic cigar case, is about to be decommissioned.

Beware the auto-complete life.
I would be interested. I made my own enclosure modifying a Hammond case
as the Takachi case isn't available in Europe. Its almost as good but a
professionally etched case is going to look much better. Don't forget
the LED light pipes.

I'm interested in the enclosure. Even if it's only supplying machined end plates. Engraving/labeling would be a bonus.
Does anyone in the US stock the Takachi enclosure or is this an import only option right now?
Interesting discussion about a case for the B210.
I have been working on putting together a suitable case for the B210 via 3D plastic extrusion (Makerbot Replicator 2) and I’m pretty close a solid design. I have a few prototypes that seem to be doing the trick around our lab. They don’t take too long to print and I think pretty soon I will try to make them available online for sale.
The design that I have isn’t fit for outdoor use nor does it have engraving or labeling. The only bonus is that they would be considerably cheaper and lighter than a machined case.
As soon as I have them available I will post something here.

So, something that people should be aware of is that the B2xx board
layout will change slightly for new units, starting sometime
soon (for a wishy-washy definition of "soon").
That won't affect people for boards they already have, but if someone is
planning on doing a stock-pile of enclosures as a bit of
"free enterprise", be aware that the board/connector layout is likely
to change in the coming weeks.
Also, if you're considering extruded plastic type enclosures you might
consider that such enclosures will provide zero RF shielding, which is
one of
the two prime reasons for having an enclosure.

Hopefully, one of the changes to the B2xx board will include PCB mount holes.
“Also, if you're considering extruded plastic type enclosures you might consider that such enclosures will provide zero RF shielding, which is one of
the two prime reasons for having an enclosure.”
At the moment the current solution of not having a case also provides zero RF shielding. I think that the immediate need of keeping some of the SMD parts from being knocked off the board, accidentally dropping your laptop onto the B210 and cracking the board, or errant ESD from destroying components takes precedence over RF shielding.

Nicholas,
A word of caution about home brewed plastic cases. Production plastic cases that you see wrapped around electronics are generally specifically engineered to address ESD and EMI issues with coatings and treatments. The handling of certain types of plastics can produce about as good a source of ESD as it gets, I once watched an entire set of boards get destroyed at a trade show because some clever chap had commissioned someone to build them a bunch of transparent cases to show off the internals…said cases quickly accumulated fingerprints and were constantly wiped clean again with a cloth…..zap!

I am not encouraging a plastic case at all, but if you must use it, use
something like this with an antistatic coating:
http://www.mcmaster.com/#static-control-plastic/=rodwj8 It machines well,
but you wouldn't make a 3D case from it. I use it for clear dust covers on
sensitive electronics.

Two additional points.
-
ABS plastics come in anti-static varieties that are not much more expensive than regular ABS. It even appears that you might be able to print circuit boards, crappy as they might be. -
We have used regular PLA (non-conductive) and haven’t seen a problem but we generally don’t have problems with static discharge where we are.
I’m going to stick with the argument that not having a case for the B210 is probably a worse scenario than having a plastic case. Although if you constantly wipe it off with a silk cloth you get what you deserve.

I'm going to have to put this on hold for a while, for a couple of reasons:
-
I haven't gotten much interest expressed, and bulk/volume only
works if there's more than 2 people. :)
-
There's (apparently) pending changes to the boards coming, which
will affect the enclosure penetrations, negating any work done now
Thanks!

Subject: Ettus B2x0 enclosure group buy/machining interest?
I've been doing a little research on cases for the Ettus B2x0 series, and
wanted to talk to the group about interest in some sort of group buy, or at
least group machining. I have one of the Takachi enclosures, which is a
perfect fit for the board, and the price is about 21 USD in the volumes that
we're likely to do. That includes silver finish, and aluminum endplates
(unmachined). They have the same enclosure with ABS plastic endplates,
though, for about 8 USD. I don't think that the plastic endplates will work
very well, though.
I have a local friend who owns/runs a mid-sized machine shop, and will be
taking him my enclosure to see what the cost to CNC machine the aluminum end
plates. I'll have him look at both machining Takachi-supplied end plates
(so, the 21 USD enclosure), as well as making end plates from blank aluminum
stock (so, using the 8 USD enclosure). He can also do laser engraving, so
will get pricing on labeling the end plates as well.
The absolute easiest thing for me/him to do would be to just machine the end
plates from stock, and you get your own enclosure from Takachi. But, while
the Takachi company was extremely pleasant to work with, there's still the
back and forth across time zones, etc., and I'm not sure about the costs of
the different options yet to say which would be the absolute cheapest.
How many people would be interested in a bulk buy/machining? How much would
you be willing to spend for a complete enclosure, with CNC-machines end
plates for either the B200 or B210? Both of those numbers will help me when
I talk to my machinist.
Also, Ettus folks, if there's any interest in me getting you in contact with
my machinist for a possible "official enclosure", please contact me offline,
and I'm happy to put you in touch. I have a day job, and would rather spend
my free time playing with my B200 than coordinating shipping, etc.. :)

enclosure", please contact me offline, and I'm happy to put you in touch.
I have a day job, and would rather spend my free time playing with my B200
than coordinating shipping, etc.. :) Thanks!Robert

Robert, I would be interested in a group buy. I just purchased a B200 a
month ago.

I used this with a B200.

These are 100% aluminum enclosures for $20. I drilled the endplates
and attached bulkhead connectors.

volumes that we're likely to do. That includes silver finish, and
aluminum endplates (unmachined). They have the same enclosure with ABS
plastic endplates, though, for about 8 USD. I don't think that the
plastic endplates will work very well, though. I have a local friend who
owns/runs a mid-sized machine shop, and will be taking him my enclosure to
see what the cost to CNC machine the aluminum end plates. I'll have him
look at both machining Takachi-supplied end plates (so, the 21 USD
enclosure), as well as making end plates from blank aluminum stock (so,
using the 8 USD enclosure). He can also do laser engraving, so will get
pricing on labeling the end plates as well. The absolute easiest thing for
me/him to do would be to just machine the end plates from stock, and you
get your own enclosure from Takachi. But, while the Takachi company was
extremely pleasant to work with, there's still the back and forth across
time zones, etc., and I'm not sure about the costs of the different
options yet to say which would be the absolute cheapest. How many people
would be interested in a bulk buy/machining? How much would you
be willing to spend for a complete enclosure, with CNC-machines end plates
for either the B200 or B210? Both of those numbers will help me when I
talk to my machinist. Also, Ettus folks, if there's any interest in me

I have a new B200 which has holes in the PCB and the bigger USB 3 connecter,
as a result of the PCB holes mounting is much simpler. I'm looking at a
die-cast box designed for outdoor use, this box comes with N-Type plugs
already mounted, typically these boxes are used for outdoor Wi-Fi.
I'm looking at a 3m - 4m dish in the back garden with the B200 mounted as
close to the feed as possible. I may well put a mini-ITX i5 out in the
garden as well, just not sure yet.
Plans can always change.

There wasn't much/any interest, so I just got mine done and left it at that.
Cheers,
Robert
