Well I guess it's been a couple years.  What can I throw on here from our chat server?  Hmmm..

here you go:

Converts old pennies into usable AA batteries

Evanescent lighting principle with NIR and a camera to detect input on a MASSIVE multitouch screen.

Powder 3d Printer

Turns out that your speakers have harmonics!!!  If you record a sweep, you'll notice that the sweep has sub-sweeps and that the speaker stops playing sound above a certain frequency even if the sample rate of the sound card will allow higher frequencies

I got a widget from styropyro(the youtuber) and true to theme, I reversed part of his fingerprint from it with a laser.  The other bits are skin cells... the fingerprint was a happy accident in my quest to show my children they're filthy yet beautiful.

Oh and the booths from one of our previous posts are half assedly have done.

 Upgrading the computer lab to a computer..  uhm.. VR/laptop...  uh... podspace?

We're making 26 of these and fitting them/ upholstering them together so we'll have hexagons and not trapezoids

Too many people are asking us about my efforts fighting COVID.  I'm going to put all my content relating to that here:

MASK MAKER(EXPONENTIAL)

Fancy tech that makes masks exponentially(up to around 200 masks per worker per hour).  Costs about $1 per mask.

Reference Model 

A nestable mold master for pouring unaltered Montana Masks

The printer doesn't matter as long as you can fit the massive 6 1/4" x 8 1/14" (70cm x 210cm) object.  You can print with rigid ABS, PLA, a flexible Nylon, or anything that will easily hold its shape. Use a 100% infil as you will be clamping this part.  The finished print needs to have at least a shore A hardness of 60 or more. I produce each mask at $0.98 and the rubber for the mold is $12.64
 

 You're not making a mask with the printer.  You're making a two-part container to cast molds(from ecoflex or moldstar) to make masks.  Then pour masks out of Smooth-on's 61D or Task 8(if you need the mask to survive an autoclave).  This sounds like a lot of work, but there are cumulative returns on your effort!  That means you'll produce masks exponentially. 

Create N-1 masks per hour where N= the molds you've casted.  On Apr 20th, I created 50 masks.  On April 21st, I was able to increase production to over 100/day while still working and only using my 15 min breaks, lunch hour and some time outside of work.

For example, if you poured 15 molds, you can create 14 masks an hour or  168 masks per day without a 3D printer.  If you 3D print five mold masters, you can cast five molds at a time!  This will scale more exponetially than the virus is infecting people!  Go team Humans!

Note that 61D can't go through an autoclave, but in talking to hospitals, they're just using bleach water here in Montana.  Smooth-On recommends using Task 8 if you want your mask to survive the autoclave.  Bleach water has been proven effective on a ABS FDM version of this mask via a culture test.  Culture tests are a good start... but they don't indicate the irradication of a virus.  Having said that... bleach kills over 99.99% of viruses and Covid19 is proven to be one of them. 61D has much lower porocity than ABS FDM.  It should perform far better when washed with bleach water or even wiped with a Saniwipe.  If you pour your masks with Task 8, it will be able to withstand an autoclave.
I recommend using long clamps to hold the molds together.  I stop at sections of 15 molds because my clamps aren't long enough.    15 molds per clamping might be a good number to stop at anyway.

NIOSH PRETESTING RIG (N99 MASK)

blarg....   see two blog posts from now.  Copy/paste was giving me grief and I want to spend more time actually researching and developing cool shit instead of communicating to others why our work is important.  Really, why do people even have to be convinced that we're awesome at this point?

Here's a blurry old image of our Board scrubbing/painting walls.  We've since created a circuit board pattern on all of the hackspace walls and erected dividers from hastings shelves.  We've also seemed in a circuit pattern into the carpet for the front room(and half of the eng/incubation rooms).  much of the junk is on shelves now.

You'll notice the burnt out lights.  I like the dark... but I'm going to install new fixtures this month.   One of our awesome members is an electrician and he's helping me to not suck. Here's the lighting diagram.

Hope to see you soon!

Pics of upcoming building

MEH will be GLORIOUS! Jan 12th!  We are moving into a new place.  Here's something to tide you over:

Tentative plans for new floor layout.  Hacker lab may get converted to Aquaponics Lab.

There are certain people I have made MEH for.  These are passionate, hilarious, yet lonely nerds.  Nerds--who are alone even when they're around others.  These people are the reason I want MEH to exist.  

Sometimes conversation... good... brilliant... daring conversation is like good sex... but it can last an entire day and can give birth to a beautiful idea(instead of a whiny miniature flesh golem waiting for some semblance of soul to be bludgeoned into it by the iron-cold hammer of reality).

Smart people can get really suicidal if they don't have opportunities to share their dreams and passions.  You essentially could die from blue-balls of the mind.

I'm just assuming that everything feels like shit right now.  Hang in there.  The hackspace is starting up with a loud "BLARGGGGG!!!""  over the rooftops of the state capital on Jan 12th!

PS:  Pics, or it didn't happen in my mind:

Engineering Bay

Welcome room(with crafting)

Hacker Lab(may become aquaponics and our competitive security team can just use the classroom)

Uhm... a hallway... with ADA access to our bathrooms 

Aforementioned Classroom(Only 5 students seats available, we don't intend on teaching large classes)

Electronics Room

What more do you want?  You want renderings of the bathroom?  go away!  Come back in a month!
