Just slightly bigger than the average coffee grinder, the
"Quiet
Morning" TM grinder silencer works like this:
Open the clear case, plug your unit into the outlet provided
inside.
Close the airtight door and push the button which activates
the
silent air pump evacuating the air out
of the unit.
Push the grind button that turns the unit on. If you've got the
kind you need to push down, push the large button at the top
that in turn pushes down on your coffee grinder.

to
dumb it down a bit.

The supports will transmit the sound to the outside of the case. |

How loud is the vacuum pump? |
|
| |
Coffee Grinder Amplifier: contact microphones on the casing feed a powerful pre-amp and power amplifier, which drives a massive array of speakers including a fan woofer. Now the entire neighbourhood can hear you grind your coffee. |
|
| |
Low-tech coffee grinder amplifier: The grinder is bolted to the centre of a 8x4 sheet of plywood which is supported at the edges. |

Yea, it would need to be carefully designed. the feet would
be
well insulated from the body and the vacuum pump woud
be
encased in a solid air tight container. But it would be in the
envelope too so even if it made a slight buzz it would
quickly
fade out. |
|
| |
Hey, that would tell you it's ready! |
|
| |
Wonder if you could take your contact mic and amplifier
and do a
phase cancellation thing? |
|
| |
By the way, goes without saying that having a coffee grinder
with this included from the factory might have a market. |
|
| |
Okay, now I have to look into actually doing this. |
|
| |
Occurred to me that after you silently grind your coffee,
you put it into a special container with a one way air valve,
put it in, hit the vacuum button and now you're just stored
your fresh ground coffee in a vacuum. |
|
| |
THAT might be the thing that pushes this over the finish
line from weird idea to something that people actually buy. |
|
| |
Sharper Image here I come. |
|
| |
huh? Well I suppose if you enclose the vacuum pump in a vacuum, the vacuum pump will be silent. |
|
| |
Well, mainly it would be insulated. Vacuum pumps are a lot
easier to keep quiet than a grinder. |
|
| |
Maybe we can do a range of products with my vacuum
blender? <link> |

//I'm surprised they couldn't come up with something
better?// |
|

They've invented the cupboard. They did a bad job of it
too, one of the first priorities would be sealing, which they
haven't bothered with. If there are air gaps, then the air
inside is connected to the outside. Seal the doors with foam
or something, and you improve things a lot. Then, the
sound has to vibrate the enclosure, which then has to
vibrate the air outside, energy being lost as heat in the
conversion. |
|
| |
//stored your fresh ground coffee in a vacuum.// |
|
| |
I suppose this means there's no oxygen to worry about, but
won't this induce the coffee to off-gas it's volatiles? Do
coffee people like the volatiles? |
|

Wait, bs0u0155, was your Vacuum Blender idea
exactly the
same a mine? Either you've figured out a way to go
back in time or you've already suggested this, no? |
|
| |
// your Vacuum Blender idea exactly the same a mine?// |
|
| |
No, mine was a blender, yours is a coffee grinder. I can see
shared marketing opportunities, however. |
|
| |
Mine has the vacuum container thing I guess. Go in
halves? I won’t get stuff made in China anymore
though. Human rights over profits eh? Looking into
South Korea which I totally support. Maybe India. |
|
| |
//Human rights over profits eh?// |
|
| |
That's got to have good karma connotations. However, using
the same logic, you have to wonder what people did to
deserve having their human rights abused. |
|
| |
Having just read the declaration of human rights on the UN
website, I wonder how they came to be held in high regard?
As a document, it's self-referential, sexist and redundant by
#4. They should really bring in a good writer to tighten it
up. It reads like it was bashed out over dinner by a group
with mixed linguistic skills. |

Not saying it isn't, (yet) but how is it sexist? I see //without distinction of any kind, such as... sex// and //No one....//(shall be subjected to x) and //All are equal/// That's as egalitarian as you can get. |
|
| |
Oh, I do see://Motherhood and childhood are entitled to special care and assistance// which is gynocentric and excludes the rights of fathers. But I would argue this is merely an artifact of our collective inborn and instinctive gynocentrism, which is a result of most non-gynocentric people failing to have children who lived and non-gynocentric societies failing to pass on their memes. |
|
| |
//Not saying it isn't, (yet) but how is it sexist?// |
|
| |
"Brotherhood" stood out to me, and I'm not exactly the
sensitive type, particularly since the word is brought up when
it's not necessary. |
|
| |
I rewrote the first few as an example in a new idea. I haven't
even finished carefully reading them yet, but I reckon we
could trim at least 4. |
