Vacuum idea

Toying with the air hose after filling with my tire, I sit in the car and dust the surfaces. Often, the dust is too thickened or too stuck to the plastic and nothing much happens. I blew all the FOD from my change pile; crumbs flying everywhere. 

This air machine gives a bunch for 75 cents. 

I turned the tip towards the carpet and the pressure blew a clear path of sand out from the carpet. The 1/8″ path of air had bulldozed a full square inch in seconds, leaving pretty blue carpet. 

…yet the debri was only blown inches away. The air ran out. 

Then two days later, I needed air again. I quickly went for carpet after the tire. I managed to sweep a patch of six by six inches. Fairly quickly. I did realize in process that if a vacuum was added to the region, then the dust could be collected. 

A brushless vacuum is basically the idea. Using air pressure. I’d imagine this gas already been applied to vacuums  — I wonder how well it works. Strap say five to twenty of the high pressure air nozzles with a broad stroke vacuum. Air knocks things into the air, vacuum is the large net. 

I wish my car was prepared for a sketch. Perhaps later. 

Engineering questions regarding juice press manufacture

I want to create a simple hydraulic press (up to 10,000 lbs) for juicing. 

A is the pan of a thousand tiny holes. B is the plunger. (NOT to scale)

Both A & B could be made in any way, but if I were to CNC the pieces from a metal — what all needs to be done to it afterwards?

 And what options do I really have?

I’ve always seen “food grade” stainless steel, but is that a designation when buying material or the processes which treats the metal during manufacture?

My initial questions:

  • If I were to manage to get our machinist where I work to CNC the surfaces on which food is in contact, (besides standard soap & water), how do you wash to remove all oils & such that had contaminated the metal?
  • Is there an actual “food grade” metal that should be used?

Other questions are as such:

  • Is there process that needs to be done to harden for pressure?
  • How thick to resist pressure?
  • How thick to resist pressure & fatigue long term?
  • If I used pipe (welded to) plate for a plunger assembly, are the same processes applicable for cleaning?
  • What is the preferred grade of cress to use for the application? Or would alluminum suffice for the project?

The design is very basic. Mash the pulp of fruits/veggies, which is held in a mesh pouch, by a plunger. This slowly forces juice through the drain holes with 5 tons (max) of pressure. 

The press needs a gearbox possibly to slow the speed of the press. As you don’t want to release the juice quickly. 

… 

Thanks in advance to the engineer who I’m asking this to!!

The response: 

“You would probably want 18-8 or 18-10 stainless.”

I will query him again, after I do my own research and/or ask another guy.

Gundam 

I’m attempting to model some Gundam dude. I have a picture for reference. I’m not creating a duplicate, but a near copy. 

…here so far, creating a piece every day or two. And each piece will likely be further editing, copied, & revised eventually. It will be a slow process.


Yes, using CATIA at work, but fully off the clock.

A couple days ago, I 3D-printed what I have so far. It’s not much more than above. My attention has been focused on other things lately. 

Not really sure what scale it ended up at. I was using near 2 cubic inches of material. I believe, 1.84 is where it landed for volume of plastic. 

  • Material: PC polycarbonate 
  • At full scale, the thicknesses of those materials would range from 0.080 – 0.20. Ultimately, it is a human sized model. 
  • However. I believe the idea of GUNDAM is that these robots are actually huge. Like 6 stories tall. But I dunno or fully care as of yet. 



Comment to blog post while searching “CAD Workstation for rent”

Www link

Stumbled upon this while looking for a CATIA workstation rental. After reading half, I realize this is a fashion blog and I am an engineer!! As such, I design within the aerospace field, but sadly cannot quite afford a $50,000 per year cost for a lisence (plus a $3,000 cpu to properly run it). 

However, I could afford to rent a cpu and a few hours per month of use on the shareable lisence. There are many specialty workbenches available that I’m sure cost a fortune to buy. As occasionally the hundreds of engineers within our network (at both Gulfstream & B/E aerospace jobsites), we use ALL available lisences and must ask for others to drop theirs. 
With that said, within engineering, you could offer CATIA (aerospace), AutoDesk – original CAD: Inventor for mechanical, Revit for architectural (they actually have rental software now), SolidWorks is huge in many industries, Unigraphics is dying, & other industry specific cadd software. 
For people like me with thousands of ideas that come and go and get sketched on paper. Well that’s great and all, but ink in on paper only illustrates so much. I want to look at it and add details and build onto my one sketch. 
For the idea, preferably I’d like a “school” to go to. Where I use a workstation with high end monitors and have a chance to meet other like minded folks to exchange ideas and perhaps even business ideas. But school sucks; they charge fees for things in which I care not and force you to take multiple classes… I want one class: drafting/engineering. 
Even though I cannot relate to the group of pattern-makers specifically, the idea is great to me. But given the fact that my perspective disagrees with most, I have serious pessimism towards the idea for a productive investment (of $$). If you are able to find a few individuals to begin with and can finance, I would go for it. 
The best ideas have ALWAYS been doubted by society.

Star Wars: Rogue One_IMAX_Review

On Friday, a friend and I went to the IMAX version of Star Wars: Rogue One. Upon exit of the theater, my friend declared the movie to be “Epic!”, so I agreed that it was pretty badass. We exchanged a couple scenes and then, luckily for my akward self, said our goodbyes and parted ways. 
I really didn’t watch much of the movie. I could barely tell you the plot of the movie or any of the character names. 

During the first ten minutes of the movie, I was thinking about how the 3D effects of the opening screen of the Imax logo are an amazing experience. That scene likely had major attention placed on it by Imax execs and ultimately made wonderful. 

This thought line started just as the movie began. My friend was upset and commented on how there was no opening story [in text that horizontally scrolls at you]. I’m guessing because this is the beginning and there is no story leading to it. And then I quit watching the movie for a while. I mean — I was watching it, but I was questioning the whole design of the theater experience. 

Bruce Almighty was the last movie that I saw in a theater before last year and I’ve only seen Imax versions of movies since. I’ve watched 2 Star Wars and Doctor Strange. That’s a gap of 13 years.

My thought process ran the gambit of questions surrounding why people come to see these things all the time. I’ve never cared for them cause they are expensive and abandon all laws of movie-watching comfort and that’s even an improved grade of Imax. The split seats that rock are nice, but if you do rock -YOU ONLY OWN ONE ARMREST and thus irritate your friend. I have to sit like a good, upstanding American with my knees parallel to my butt and feet on the floor. Or shift my legs to the empty seat to my right. Cause THERE IS BARELY ANY LEG ROOM. I can’t sit still because I just want to sit indian-style and the seats are too narrow to achieve this. 

I mean – really – I’d like to recline my chair to a suitable lounging position with my feet supported by a soft pad. I want the air to be cool and crisp. There should be a blanket to cuddle-up with, a little table to set stuff on, and there should be icecream –like what’s with popcorn for fourteen dollars?– I don’t get it. 

And now here’s where my mind went soon after: before long, there will be virtual reality and/or hardcore 3D video that will allow semi to full immersion. With this, how will theaters incorporate the new tech while bringing in mass groups to share an experience together? As is now, we all watch the same screen with one projector. We all listen to the same speakers. And the majority of folks sit elbow to elbow with friends and strangers while trying to not annoy each other. 

What I can imagine is each person needing their own headset to become fully immersed in a video. We may all share the same feed, sit in the same spots, but have scuba looking goggles strapped to our faces. Sounds like a happy version of the Matrix, where we can all go home afterwards. And also sounds like a pervert’s dream come true with all those bodies exposed and blindfolded–would need lifeguards of sorts. But the auditorium could be lighted a bit to aid in the watch and during bathroom breaks. 

That leads to another thing, if we all have the same movie, well – you’d want to pause to pee or grab more popcorn. That causes many problems:

  • You can’t share the audio (and other experience like vibration, smells (when smellivision becomes reality!!), or whatever other possible future effects to hit other senses. 
  • Oohs and aahs do not take place together and that is one of the social aspects of enjoying movies together–I know I watch others’ reactions at home during scenes they’d enjoy more than me. 
  • There would be a range of film time to allow breaks and/or timers added to breaks to prevent abuse and allow the full movie to play through. 
  • Etc, nothing else comes to me at this time. 

And pluses, like:

  • Shorter lines for concessions due to ability to pause the film. 
  • No worries over loud popcorn eaters and talkers. 
  • No need to hold the bladder
  • Etc. 

Another idea that kept bothering me throughout the entire duration of the movie compels me to want to see the same movie in 2d. I wanted to look into the background and see the faces of unimportant (for the moment) characters — especially the terrain and landscape views of the horizon. I like to look at reactions, postures, and more subtle features than is allowed by a greyed out fuzzy image. I noticed that in that viewing, the movie felt overly controlled. Like on a roller coaster, there are 2 paths: keep the seatbelt on and follow the course or remove it for a straight fall to your death. There are only a couple images to look at in any scene. I felt limited and constrained to a perfectly crafted story. During an escape scene, I could not even imagine an alternative path because there are only certain features highlighted to see with clarity (this is an unreal example that I imagine). 

I thought about the goggles or glasses for an extended time. At some point those glasses will be obsolete. Red/Blue lenses already feel antiquated as is. Will the next phase lead us to scuba masks or will it lean towards GoogleYeye or iGlass modules — transparent lenses with all the 3d effects happening there, a half inch from your face, in response to the movement of your eye and the position of your eyeglasses compared to the screen. 

Perhaps the the technology to project 3d images onto xyz points in space will allow real 3d experiences to take place. Holographic imagery would be an amazing leap even if the detail is like pac-man or 80’s monster films. It would quickly improve. 

Anyway that was a good half hour. I didn’t know the details of plot and my friend mentioned things occasionally–I couldn’t hear him, but I’d wonder what he said and then looked at other people and realized that a large chunk of the social aspect was already gone. We are almost already in the scuba mask. 

P.S. That was the 1st thirty minutes. In a 134 minute film, five or more less intense versions of that thought process occur on any number of ideas. I really barely watch tv when I do watch tv – that’s a chunk of the reason I used to watch different movies multiple times as they came on H.B.O. My station rarely changed when I was a teenager.
