18 February 2020:  The Electrics Module


I’m closing in on the end of the build.  Not much more left to create before I disassemble, paint, and then reassemble so that a story is told.

At this time I’m working on the Electrics Module.  It is this module that will contain everything that is electric with the exception of 1 microswitch.  One module.  The electrics module contains the motor, a push button, a DPDT toggle switch, and a circuit breaker.  The microswitch is not in the module, rather it is mounted at the other end of the automata.  I am creating it such that it would be very difficult for someone to accidentally touch a hot wire.

In the image you see the beginning of the Electrics Module.  The motor is mounted and it hangs from two transverse shafts.  

On the 3D printing front…I am working with TinkerCad, Fusion 360, and Blender.  There is a learning curve associated with each program.  Before I order the printer I want to know for a fact that I can work with the bipeds.  Apparently I’ll be working in a mesh, or T Splined environment.  Once I know that I can manipulate the bipeds in software I’ll order my machine.

Looking out at the world right now it is the Corona Virus that is speaking loudly.  This is a virus that started in China and that is migrating around the world.  Many things are being touched (not including people).  For example, Disney has shut indefinitely two theme parks in Asia.  Container shipping is affected.  We went to the vet today and I asked her if the virus was affecting her…it is…she gets many of her fluids from China.  So she is ordering heavy at the moment.  We order from an awards supplier (our name tag magnets).  We received an email from them yesterday warning that there could be shortages.

No one knows right now, except our President.  He says it will go away by itself.

I’m wondering if this is the one that will take out humanity.  Who knows?  I don’t.  

On a personal front, we feel comfortable here….we don’t need to go anywhere…we have food on the shelves…we can stay away from other people.

 

The Electrics Module is taking shape.

 

4 February 2020, Pulsing and 3D Printing


The campak now includes 5 cams, with the most recent being the cam that turns on the pulsing.  One of the features of this automata will be the convict ‘shaking’ while he is being electrocuted.  I’ve played with the idea in my mind for months and have just recently built two versions of the pulsing mechanism, the second of which seems to be what I want.

I attended a Miniature Show in Del Mar this past weekend and found a doll seamstress who is willing to sew the outfits for both the convict and the guard.  Good news.  I was sort of dreading doing the clothing myself.

I’ve immersed myself into 3D Printer prepurchase activity.  I looked at 3D printing three or four years ago and was not compelled to move into the field.  3D printing has done a lot of maturation in the last few years and I now feel that it is time.  I had been lusting for a miniature lathe and mill.  When I carefully consider what I would be creating I find that a 3D printer is better suited to my needs.

Critical to 3D printing are the ‘filaments’ that are used.  I was pleased to note that in addition to purchasing strong stable filament (for gears, pulleys, etc.) I can also obtain filament that is wood, copper, brass, aluminum, and bronze based.  These last specialty filaments all contain PLA also…none of them are pure material.  But for my purposes, I feel that they will be useful.  

A primary use for me will be biped printing.  The bipeds are 11″ or so tall so I need a printer capable of that height.  At this time I’m considering a delta style printer, a FLSUN QQ S,  It looks like an interesting and capable printer that is receiving good reviews.  So for example, instead of needing to copper leaf my bipeds, I should be able to simply print them using the copper filament.

As I do this research I continue to be thankful for the Internet and for all of the information that is available to me (us).  What would have been so difficult that I perhaps would not have done it is now relatively easy.  One of the things that I love is the fact that I can access the writing of so many people…so many thoughts and opinions.  We are very rich right now.

Five of the six cams have been cut.

 

25 January 2020: The Scroll Saw


One of the important tools in my studio is my scroll saw.  It’s a Ridgid brand.  I bought it used for $50.00.  Immediately after it arrived in my studio I took it apart…inspected it…lubed it…put it back together…and have used it happily for the past four years or so.  It’s a very nice tool.

I had more difficulty with blades.  First is the issue of blades with pins in each end, or pinless.  Next is the issue of how many and what kind of teeth.  And lastly is the ‘which brand?’ question.  I’ve settled on Olson, 18.5 tpi, pin end (p/n 42401).  I’ve tried about 4 brands.  To me Olson is clearly the best.  18.5 tpi works well for the materials that I cut which are usually between 1/64 and 3/8″ thick.  And pin end because they are much easier for me to install.  My old eyes struggle installing the plain end blades.  I try to keep 10+ blades in my studio at all times.  It is not a good day when a scroll saw blade breaks and there is not a replacement at hand.

In the image you see the two new version 2 side frames being installed into the Drive Frame.  Hopefully I’ve thought this through enough that there won’t need to be a version 3.  Side frames are critical components that require a lot of time to fabricate.

I use french curves to help me with the layout of these frames.  I prefer gently curved lines to straight lines.

 

Side frames, Version 2, are being fitted into the Electric Chair drive frame.

 

 

17 January 2020, 4 Motions are Linked


First let me report that my brother came through open heart surgery with flying colors…what an era we live in!

There are six cams in the campak.  Of those six four have been connected to their components…and all is well.

Remaining to connect are the two motions that will utilize the ‘pulse’.  I think I know how I’m going to do it…now I just need to build what is in my mind.

It’s at this stage of the project that things are coming together and that more ideas start flowing into the mind.  Some of these new ideas are valid and I will take action.  Others are just part of the creation process noise.

I’ve been reading a blog about a 47 foot trawler that is exploring the southern tip of South America.  The story is very interesting.  I doubt that Cheryl and I will ever get that far down…but it’s pleasant thinking about it.

Part of the process of creating automata is having what you need at hand.  I’ve spent thousands of dollars and about three years building adequate stock.  It’s paying off.  I am able to create much faster than I used to be able to.  Not that speed is the goal…it’s not.  What I mean is that there is less stopping to wait for something.  I’ve got a spread sheet that I utilize for keeping track of inventory and parts orders.  The spreadsheet helps a lot.

Sorry that the image does not have more detail.  The detail is hard to photograph in a manner that makes sense.  What you should notice is that the Drive Frame (the lower part) is filling up.

 

Four of the six motions are now linked to the campak.

9 January 2020, The Cams are going in…


Happy New Year everyone.  Time sure goes fast as I get older.  Time seems to be flying.

My brother is going to have open heart surgery next Monday.  Imagine that.  They are going to open his heart and repair it.  What an age we live in!  And then there are some of us who create these little cranky machines that we hope might make someone smile.  There is lots of breadth and depth to life.

Regarding the Electric Chair #1, I’ve made two decisions that I’m very pleased with:

  1. I wanted the top (the automata proper) to be removable from the bottom (the Drive Frame).
  2. I wanted to be able to easily remove and replace the CamPak.

In hindsight…I’m glad that I made these two decisions.  The build is going well.  I’m in the finicky stage of the build…the part where I actually make the things that move…move.  This is the time to ‘take your time’, to go slow and lovingly, to care about every little detail.  Proper motion is so important.  Improper motion seems to sort of wreck things.

Our President continues to stress me out.  I feel guilty because I am trying to just “shut it all out”.  I know that’s wrong to do.  But it eats me up inside if I think much about it.

The Cams are being installed into Electric Chair #1

 

30 December 2019, Product Spinner


It’s almost the end of the year.

It’s almost the start of another year.

Time is running short.  I’ve got perhaps 20 more years to go…then I’m out of here.  As I write this I’m approaching 75.

As I’ve aged I’ve gotten better with time utilization.  I have many fewer non-essential things and activities in my life.  I am much more focused.  It’s easier getting from A to B because the lines are straighter.  I like to think that I’ve finally become “who I am”…as opposed to being someone who was trying to be.

I have been taking Big Wheel Lift into public with me occasionally and I keep noting that people are very attracted to it.  They stop and study it, and marvel at it…and seem to receive joy from it.

This has gotten me to thinking about how to get my automata into public more often.  I am contemplating what I think of as “Product Spinners” that I rent to stores.  A Product Spinner would be a biped powering some sort of machine, part of which includes a platform perhaps 3″ in diameter that turns.  Product would be placed on the platform.  The Product Spinner automata would sit on a counter top and would be a point of interest, an addition to the ambience, and a conversation opener.  I’m thinking rental in the $30-$50 month range.  We’ll see. 

The image to the right shows the side frames for the drive frame coming to life.  This is the first set of side frames.  I’ll admit that I’ve never had the first set on the final automata…there always seems to be critical improvement that I must make…so I bite the bullet and make new ones (perhaps two or three times).   I like these ‘lattice’ frames, because you can see through them.

I’m a little early…wishing you a Happy New Year!

The side frames for the Drive Frame are taking shape.

 

20 December 2019: A Mess


Automata don’t build themselves.  The creation process is not always neat and tidy.

Here you see me in the final stages of completing the pulleys for Electric Chair #1.  These large pulley assemblies will be dropping the 60 rpm speed of the first shaft to 1 rpm, which is the speed required by the campak.

It seems to me that if you look at how things are arranged that you can (correctly) deduce that I am left handed. Near the top at the center is a Google Nest Mini…a speaker that I use to read audio books with while I work. 

To the left of that speaker is a stack of cocktail napkins.  I used to use paper towels but I find it much easier to use these small cocktail napkins…they help keep my creations, my workbench, and my clothes, clean.

To the left of the cocktail napkins are my sanding sticks.  I purchased these from the beauty shop that my wife uses.  The sticks that I like the most have 100 grit on one side and 180 on the other.  They cost about $.75 each and last me 3-5 weeks.  I love these little sanding sticks.

The big pulleys have taken me two days to create.  Part of that time was spent building a sanding tool…one that helps me sand the disks perfectly round on my disc sander.

Making a mess is part of the process.

 

11 December 2019: Random


I came across a scientific article the other day…a portion of which has stuck with me.  In essence the article said that scientists say that “all is random”.  ALL IS RANDOM.  I get it.  I don’t have a problem with the statement.  It makes good sense to me.

And then I step back and realize that naturally ‘all is random’ and yet humans are trying to organize it.  It seems such a futile task to me.  For example…what is ‘sanity’?  If everything is random you would expect the definition of ‘sanity’ to change over time.   What is a desired government?  Again, you would expect the definition to change over time.  Is there a God?  Perhaps at times.  And then not.

I worry about this because I am constantly wondering if I am living my life the way I should be.  Am I doing it right?  And when the concept of “all is random” is thrown in…it causes a bit of a dust up.

So I am walking around these days looking at things that don’t make sense to me and I repeat the phrase “all is random”.  It makes me feel better.

To be honest though, thinking that all is random is not making life any better.  Life is not richer.  But perhaps it is just a tiny bit more understandable.

RANDOM

2 December 2019: Progress continues, Styles


I had to slack off my automata creation efforts for just a bit last week…had a project for a customer that I needed to get done.

Automata Styles:  I’ve been giving this topic thought recently.  It’s hard to not compare yourself to others.  Here are some of my thoughts:

  • Fran├žois Junod I am not.  This guy creates amazing automata.  I envy his abilities.  My understanding is that he has training as a watchmaker.  I am very impressed with his ideas and craftsmanship. But I’m not him
  • Paul Spooner I am not.  I admire the way that Paul can let his imagination loose…at the frivolity that he is able to build into his automata.  His craftsmanship is excellent…and his ideas well executed.  But I’m not him.
  • Keith Newstead I am not. Here is another automatist that I greatly admire.  I love his ideas and the way that he executes them.  I love his whimsey. But I’m not him.

I could go on and on…bottom line though, is that I don’t create automata like anyone else (I don’t think).  I have my own ideas…and I create in my own way.  We automatists are all different…I love that about this ‘sport’.  We are all different.  There are no rules.  There is no ‘wrong’.

The image is of the back side of the Electric Chair wall, the one that contains the clock.  The clock needs to advance just 1 minute.  The minute is the difference between life and death.

27 November 2019: The Red Telephone


As I continue with Electric Chair #1 I have needed to identify the small details and the timeline.

One of the small details that is required is a red telephone.  If there is to be a ‘pardon’ the executioner needs to be able to be communicated with.

Spoiler Alert: In this particular case the Red Telephone is going to ring after the execution.  Too bad, so sad.

I’ve also got 1/2 of the shake mechanism created.  I think it’s going to work well.  And a side benefit is that the shake mechanism is going to be able to be used to ring the Red Telephone.

Initially I thought that I was going to need to purchase a small telephone…however by using my drill press as a wood lathe I was able to create a reasonable little phone.  Now I need to paint it red and then weather it.    And it needs a cord.                                     

Thanksgiving is tomorrow.  A fake holiday…but if you can get around it’s fakeness and focus instead on being thankful for what we do have I know that I have a lot to be thankful for…and I am.  I’m very grateful for the life that I am able to lead.
