AI Voices & the Current AI Controversy

Little did I know, when I started to create the new Moment of Inspiration training series that the decision to use AI voices would change my release plans so dramatically.

From the beginning, I had planned to upload the Moment of Inspiration Course onto Udemy.  But, little did I know that including AI voices to supplement my own narration would be cause for rejection by the Udemy team.

The reasons for Turning to AI Voices

Ten years earlier, when I created my first Moment of Inspiration Curriclum, my voice was strong enough to complete hours of video.  By the time I started on the new curriculum I was ten years older and, as it turned out, was having age related heart issues.  My voice simply no longer had the stamina to smoothly narrate all the videos required to teach Moment of Inspiration effectively.  

I did not want to give up on the project because I know, without a shadow of a doubt, that at-risk young students' lives have been radically altered through the 3D design and printing classes we taught at YouthQuest.  So, I wanted to continue that work if at all possible.

The first attempts at finding suitable voices to use didn't go all that well.  While Descript allowed me to use my own voice, I never really seemed to evoke the right tone behind the words.  Speechelo was OK.   But, again, I was not able to control the voices to my liking.

Fortunately, I found WellSaid Labs.

The voices I ended up using not only conveyed the pronunciation; but, the way WellSaid Labs Studio worked, allowed me to tailor both the pronunciation and the inflection to a point where the narration is 95% or above exactly as I would have spoken it.

I am not trying to fool anyone by using voice other than my own.  I simply needed a script to be narrated at the lowest cost possible while still being effective.

The Controversy

 The rejection of a course simply because it includes AI voices, has to be seen in the broadest context.  We have jumped into AI so quickly that the full ramifications of the technology are totally a mystery and the potential for harm, in the broadest sense, are certainly there.  I assume that Udemy is simply trying to get ahead of the Intellectual Property curve and it's easiest to simply develop a blanket ban while the technology is being sorted out.

But, from this one small corner, I would like to address my own experience with using WellSaid Studio as part of the workflow of my course development.

Using AI Voices Improved the Content

I have been creating video content since 1969, when I begin with a used Sony TVC-2010.

One of the realities that has remained the same in all of those years was how difficult it has been to match sound levels between takes.  It was a VERY pleasant surprise to discover just how seamlessly it sounds when new AI material is inserted into previously recorded segments.  This allows for improvements and additions to scripts in a way unmatched by live recording.  I found my narrations getting better in the editing process because I could reflect on what had been there and make it better and more clear so easily.

The other aspect of using AI voices that I believed helped the content is that it put me into the role of director, rather than simply writer/narrator.  Hearing the words I had written in a voice other than my own allowed me to refine what I written and work harder on getting the inflection to convey my thoughts.  It was a remarkable experience.

Using AI Improved the Flow

Designing in 3D is a multi-step process.  Being able to change narrators to indicate a new series of steps or a new focus of the course content was another benefit of using  AI voices to augment my own narrative.  

The two voices I most used were identified as Ava M. and Wade C.  But, even within those voices I was able to select different styles based on the subject matter being delivered.  The only issues I had as I switched from voice to voice is that Wade C., using the "Conversational" style was considerable louder that the other voices.  But, this was easily dealt with using the Limiter and Loudness Normalization effects in Audacity.  

Summary

Quite frankly, it was a big bummer for me when Udemy would not allow my course simply based on the fact that I had used AI voices.  But, in the grand scheme of things, that loss pales in comparison to the benefits that AI voices brought to the project as a whole.  I don't know how negatively AI might impact society in the long run; but, I can attest to the terrific value of AI voices in helping me overcome a disability to allow me to complete something very important to me.

The new 3D Design for Fun and Life Course.



Published a New Series of Moment of Inspiration Lessons

I completed the first phase of a new Moment of Inspiration, Version 4, course for public release. 

It can be found at:

   3D Design for Fun & Life

Most of my readers know that ten years ago, while with YouthQuest Foundation, I created an original 3D design curriculum, around Moment of Inspiration (MOi3D), specifically intended to change the trajectory of young at-risk lives in National Guard Youth ChalleNGe programs we served.  We started with MOI3D Version 2.

 3D Systems made a huge contribution toward that initiative with the donation of 32 Cube2 printers.

The combination of creating a 3D design, seeing their design printed and then refining that design to make it better, brought a powerful and much needed message to the population we served.  "Your failures are not final." 

Along the way, we ended up using the curriculum to a much wider base of at-risk students, across four states and the District of Columbia, including those on the autism spectrum.

I am very thankful for having worked at YouthQuest and having seen so many young lives impacted.

 


But, YouthQuest was a very small not-for-profit that lacked the resources to expand  its reach.  A little over two years ago, it ultimately lost its primary funding and made the decision to shut down, transferring its property, including the 3D curriculum, to another not-for-profit.

At the time, we had hoped our relationship with the many groups we served would continue.  But, the successor organization had more localized interests and a very restrictive view of "intellectual property rights".

Based on the above video.  I am sure you can understand the sadness I feel about that loss.

I absolutely loved what I was doing through all of those years.  

But, in the back of my mind, I always thought that more should be possible.  I know the impact of Youth ChalleNGe programs and I know the impact  that learning 3D design has on at-risk students.  But, I always felt many more could be helped if the curriculum were released to a wider population.  That feeling became even stronger as 3D printers dropped in price from above $1200 to under $200.

The additional capabilities introduced with the release of Moment of Inspiration Version 4 makes it an even better fit for the classroom. And, which makes it a great time to bring the experience of learning Moment of Inspiration to, hopefully, many more at-risk young people.

I have been committed to creating an even BETTER 3D curriculum around the wonderful Moment of Inspiration V4 to be released on online learning sites at a very low cost.  It has been being designed from the ground up, taking into consideration all of my experiences learning and teaching 3D design and printing since 2012.

The course design is intended to allow ANY learner to become very proficient well within the free 90 day trial period for Moment of Inspiration.  The unique session organization takes into account those that need sparse information as well as those needing very specific step-by-step directions.

But, I immediately ran into a hurdle! 

At 78, I'm ten years older than the first video series.  And, that means my voice has a lot less stamina than the first time around.

Well Said Labs to the Rescue

The handwriting has been on the wall for a fairly long time.  So, I began to look into using AI Text-to-Voice to take some of the load off of my own voice about two years ago.

Of course, I immediately ran into the reality that most computer voices are just plain boring and annoying.

I first subscribed to Descript.  In fact, I even recorded my own voice using their "Overdub" technology, hoping that it would capture my emotion and inflections.  

It got the tonality right.  But, I never was able to get it to deliver the inflections so critical to holding onto interest in the content.

I then tried Speechelo.  Same result.

If push came to shove, there are some voices in both Descript and Speechelo that could be used in a pinch.  While it might be better than my tired old voice droning on and on, I don't think I would ever really be happy with the result.

Fortunately, my sister remembered an online site she had used during the Covid lockdowns.

It was WellSaidLabs.com.

I have finally found some text-to-voice voices that come very close to expressing my thoughts very closely to how I would express them. 

While I wish every minute of my training could come from my own mouth, that is just not feasible at this point in my life.  I feel very blessed that I can still deliver the content that I feel could be so crucial in changing the trajectory of the lives of at-risk young people despite the limitations of my voice.

I am very grateful to WellSaid Labs for giving me the ability to complete this project and continue to add more content in the future.

Sovol SH01 Double Wide Filament Dryer & Storage

This article is about a new dual-spool filament drying system from Sovol that has extra features that also make it useful for safe storage of filament between prints.  It's the Sovol SH01.

Sovol SH01 Filament Drying/Storage System

Background

If there is any group of people that appreciate the critical role that quality filament plays in the success or failure of a 3D printer to deliver it is those who own(ed) the Cube series printers from 3D Systems.

And, one of the factors in maintaining filament quality that we, as users, can control is making sure that our filament is dry.  While this is true of PLA, it is even more true for water-soluble support materials and nylon.

Over the years we have tried various devices for drying and storing filament.  Our first dryer was a DIY modification of a food dehydrator that we used with both Cube2 and Cube3 cartridges.  

Food Dehydrator Used to Dry Filament

This served us well over the years; but, it had two limitations.  Firstly, it could not be used while printing and; secondly, it was not suitable for storage.  For storage, we turned to five gallon paint buckets with sealed tops in combination with rechargeable desiccant canisters.

Rechargeable Desiccant

While these worked well for pre-print drying and storage, they did not provide a good solution for continuous use while printing.  Nor were they convenient for short-term storage between prints over weekends, etc.

To solve this we turned to two excellent active filament dryers from Sunlu and eSun. 

Sunlu Filament Dryer

 
eSun Filament Dryer

Both brands have served us well for the Polymaker Polymax filament that we have preferred for so long.  But, the reason we needed two for each printer was that we have dual nozzle printers.  But, what really made us make another search for a third solution was that our friends at IMade3D, right here in Virginia, began importing and marketing excellent filament from the Czech Republic, FilamentPM through their FilamentBuy.com web site. 

The spools of FilamentPM PLA are too wide to fit into either the eSun or Sunlu dryers!   The timing of of search was fortunate.

Sovol had just begun offering their WIDE SH01 filament dryer/Storage box on Amazon for $59..  It was capable of holding two Polymaker spools or one FilamentPM spools.  I am certainly happy that I immediately ordered one because they quickly sold out the first batch.  It's wonderful!

Sovol SH01 Filament Dryer


The Features That Make the Sovol 3D SH01 Dryer my Favorite

Of course, the reason why we chose to purchase this dryer even though we have two that we like quite well was its ability to handle wide spools of filament.


Sovol Dryer with Wide FilamentPM Spool

But, what we did NOT know when we ordered it was that the Sovol Filament Dryer has some features that set it apart from our previous dryers.  First, the display is WAY bigger and better, alternately displaying Temperature/Humidity and Time Remaining.

Sovol Filament Dryer  - Temperature/Humidity

 

Sovol Filament Dryer - Time Remaining

The first image above image shows our startup temperature and humidity. The second image shows the time remaining for our default 6 hour drying session.  It is SO refreshing to see auch a large and bright display!  The MODE button allows us to enter setup where we can select 40C, 45C or 50C depending on the type of filament we are drying and set our target time up to 12 hours.

Within 7 minutes our target temperature of 40C was reached and within 30 minutes the humidity had dropped to 29% and steadied to the target of 30%.  I have checked it with a 12 hour setting and the targets remain steady over the entire drying period.

Now, for the bonus feature that the Sovol Filament Dryer brings to the table.  SEALED STORAGE.

The top of the Sovol is sealed shut using two latches on the front of the unit.  Neither the eSun nor the Sunlu is sealed in this way.  Moreover, all of the openings are fitted with plugs to completely protect the filament while being stored.  This includes both of the ports through which the filament reaches the printer and the power receptacle! 

I REALLY appreciate this level of detail that Sovol has taken to make this not only an active dryer; but, a protected environment for storing filament between prints.  We live and work on the east coast and humidity is a huge problem in the summer.  

If Amazon is out of stock when you follow this LINK, then try the Sovol web site:

https://sovol3d.com/products/large-filament-dryer-box

If you go to the Sovol site before Father's Day 2021, you might also take the time to enter a drawing for their latest 3D printer.  They are giving away one FREE Sovol SV04 IDEX printer in a short term promotion. 

https://sovol3d.com/pages/fathers-day-give-away-2021

I have no experience with Sovol 3D printers; but, the care they demonstrated in the design and build quality of the SH01 Filament Dryer gives me some positive vibes.

It is Wonderful When a Vision Becomes a Reality

As I wrote in my previous article, I am more than a little thankful for the start that the Cube printers provided me.  Among other things, the Cube was a significant step forward in my quest toward my ultimate goal... finding a way to help my sculptor daughter realize her dreams with the assist of 3D printing.

DREAMS TEASED

In reality, the Cube came my way out of the ashes of an earlier product in my trek on the quest that went up in smoke when the DeskTop Factory was swallowed up in 2009 by 3D Systems.

Desktop Factory 3D Printer 2007-2009

Cathy Lewis was the CEO at Desktop Factory, and a tireless advocate for consumer 3D printing, and in the acquisition became the Vice President for International Marketing of 3D Systems.  Cathy and I had become acquainted in 2007 through my interest in the Desktop Factory development and years later, in 2011, remembering my deep interest and help in testing and providing feedback on sample Desktop Factory prints, she contacted me to be on the lookout for a new consumer printer from 3D Systems... the 1st Generation Cube released in 2012, the same year, this blog began.

I knew that the Cube FDM printer was not the ceramics printer of my dreams. But, I also knew it was a first step in gaining 3D printing experience so that I would be poised to be ready when a real ceramics printer became a reality.  And, not too many years after starting this blog, it appeared that ceramics printing was right around the corner.

Those of you that have followed this blog know that 3D System's tantalizing 2014 announcements of the $10,000 Cerajet and, in particular, the $5,000 CubeJet were greeted with extreme happiness around here.  It appeared that the end of my quest was near at hand. 

DREAMS SHATTERED

But, that was not to be.  When 3D Systems closed down the Cube family production line, the CeraJet and CubeJet became collateral damage and my dreams of seeing my daughter's art rise from a bed of powder went down in flames.  It was a hard blow.... made harder by learning that the engineers on the project had probably been scattered like ashes.
 
There some are creating amazing art with 3D printers capable of extruding clay.

      https://www.emrecanceramic.com
      https://tomlauerman.com/process

That isn't the process that I prefer.

I know, from years of experience printing with YouthQuest Foundation's Z450 "sandstone" printer, just how much I enjoy working with a powder based printer.  Yet, neither the Z450 nor the newer CJP (Color Jet Printing) ProJet series printers are true ceramics printers.  The powder used in the CJP printers is NOT clay-based ceramics and the binder is, I am relatively certain, NOT something you want to put into a kiln and fire!

And, being able to apply the glaze of your choice and fire your creation is a huge deal.

CeraJet / CubeJet 3D Printed Pottery
DREAMS REKINDLED!  THE KWAMBIO CERAMO ZERO MAX

Now, out of the Ukraine, comes a 3D printer that has rekindled those long smoldering dreams.  I don't even remember how I found out about the Ceramo Zero Max.  But, however it was, or whoever it was, that pointed me in their direction I am truly grateful.  Here, finally, is a desktop, powder-based ceramics printer that creates objects meant to be fired!

Kwambio Ceramo Zero Max Desktop Ceramics Printer
I am not going to try to post an image of the ceramics output of the Ceramo Zero Max because it would be misleading.  The Ceramo Zero Max does not print in color.  But, the most beautiful examples online are in color.  And, that is because printing the part is simply one step in the process of turning a creative idea into a stunning piece of art.  And, that process is already familiar to clay artisans.  I cannot even begin to tell you just how incredibly important this fact is to an artist.  They can print out a 3D design of a cup and, if they wish, not a single one would be the same as another.  Each can be imbued with the vision of the artist in a completely unique way using varying patterns, color, firing techniques and other personal touches.

But, I WILL point you to their materials pages to see exactly what I'm talking about.  First, the ceramics powder page:

http://www.kwambio.com/#/materials/ceramics

Next, a bonus, the GS ONE page:

http://www.kwambio.com/#/materials/gsone

I am assuming that one would need two Ceramo printers to EASILY use both materials, as they seem so different.  But, the fact that both are available is very cool.  I'm guessing that the GS One would be great for creating molds for slip casting.  But, since I have no real experience with it, don't hold me to that conclusion.

KWAMBIO HAS A USA HEADQUARTERS

I mentioned that the Ceramo Zero Max was developed in the Ukraine.  Actually, this didn't surprise me as 3D-Coat, a marvelous 3D sculpting application we've written about in earlier posts, is also the product of a Ukraine company!

But, Kwambio's international headquarters is in New York City.  And, they recently opened a new lab in Harford, Connecticut where it can continue to develop consumer, industrial and, I believe, biomedical products and materials. Both Stanley and GE use their industrial ceramics products.

Here is a story from this year's CES that overs both the industrial and consumer ceramics printers.

https://3dprint.com/233630/kwambio-new-ceramic-3d-printers/

I wish I could tell you more; but, until I get a chance to actually seen one in action, I'd simply be guessing.  But, hopefully, I will get that chance in the next few weeks, either at Ceramics Expo 2019 in Cleveland at the end of this month or their offices in Connecticut sometime in May.

I can tell you this.  Whichever visit works out, I am REALLY looking forward to it.  While not a life-time, twelve years is a long time to be on a quest!  And, I am extremely optimistic that the goal is very, very near.

From 1st Gen Cube to ProJet3500 HDMax, 3D Systems Made it all Possible!

Yesterday, The YouthQuest Foundation received a vital piece of equipment.  It was a 3000VA UPS that will help us power up our latest acquisition.  And, that acquisition is a donated ProJet 3500 HDMax multi-jet printer that we plan to be used to support our mission of changing the trajectory of the lives of at-risk young people.

A piece of equipment that requires such a massive UPS is a far cry from the 1st Gen Cubes with which we started.  While it did not come directly from 3D Systems, it found its way to us through their support network.  And, it would not have happened had 3D Systems not generously donated the very first printers with which we began our work with young students who had dropped out of school and had entered the Youth Challenge program in an effort to turn their lives around.

The steps 3D Systems took, over 4 years ago, made it possible for us to expand our 3D design and printing educational program across four states touching many lives in the process. 

One of our students, Dalonta Crudup, a cadet in the DC Youth ChalleNGe Academy, had been shot shortly before entering the program and his cousin had been killed.  He went on to go back to school and was recruited with a basketball scholarship to the University of Kentucky.  He credits the 3D design class for teaching him important life lessons.  As he puts it, “And I tell them taking that class has helped me a lot because it showed me how get through obstacles in life.”

While the Cube line of printers has come to an end, we know from our own experience, and the experience of other educational organizations and charitable programs, that STEM and STEAM initiatives begun with the help of 3D Systems continue to benefit students in profound ways.

I won't bore you with the steps that took us from our first gift of a consumer 1st Gen Cube to the remarkable gift of a professional ProJet3500 HDMax.  But, to us, it is a remarkable series of events that began with Cathy Lewis of 3D Systems agreeing with our vision of helping turn around lives through experiencing 3D design and printing.

Now we step up to the next level in our ability to serve at-risk young people by offering experience with actual additive manufacturing equipment and processes.  We believe this is going to be particularly beneficial to our graduating students on the autistic spectrum that have shown extraordinary potential for careers in 3D.

We are really excited about this new chapter.  But, we cannot and will not forget those who helped us get here.

Thank you 3D Systems!

Of Flutes, Irma and 3D Printing

I was first an inquiring potential customer, looking to buy a bamboo Irish Flute.  But, the more I learned about Erik The Flutemaker, the more I admired not only his skills as a flutemaker; but, his passion to help those in the deepest poverty through his not-for-profit, Flutemaker Ministries.

I ended up not only buying several flutes from Erik; but, a bamboo saxophone for a friend of my granddaughter since the first grade to benefit Erik's ministry to special needs kids in Nicaragua.



Ultimately, I have become a friend, attempting to use my 3D design and printing skills to help him in his work with the goal to design and print a mouthpiece suitable for some of his flutes.  It's been quite a challenge to find the "sweet spot" that equals the wonderful tone he is able to generate through more expensive and labor intensive alternatives.  I have learned a LOT!.

His bamboo grove is in Davis, Florida which is now being affected by Irma.


He just sent me this link, knowing I was concerned for the safety of him and his family.  I just had to share it with you as Erik's skill and his spirit comes through so impressively.   The sound track is him playing one of his flutes.

I'm hoping that you, like I did when I first learned about Erik the Flutemaker, will completely explore his web site and enjoy the beauty of his music.  And, I hope that some of you might consider buying one of his flutes that benefit Flutemaker Ministries.

WOW Scope! A tool for the whole family

UPDATE:  I contacted Gorilla Scientific and the scope in link #1, IS an SMD-09 having two sets of eyepieces.  It is in a different box; but, functionally the same.  In fact, the ones I purchased so far are in the 1st version of the packaging and say "Worlds of Wonder Scope".  So, I'm confident that either source is a great one.

As many of you know I have relied on a variety of microscopes to evaluate and explain issues in my 3D prints.  I've previously posted that my favorite scope, among many that I own, is also one of the least expensive.  That scope has now been improved and expanded and, not only does it remain a terrific bargain, it expands on its price / performance value by adding two levels of magnification.
WOW Scope from C & A Scientific
The first versions upon which this product is based were 20x magnification.  That was wonderful for viewing things like 3D prints, bugs and just about anything curious that you find around the house.  But, the WOW Scope also includes eyepieces that boost the magnification to 50x!  And, it adds a bottom light along with the top LED light.

When searching for the correct microscope, I wish that we could simply enter "WOW Scope" to find it on Amazon.  But, you will have to enter "WOW Scope SMD-09".  Even then you will have to be careful and look for the following feature to ensure you are going to recieve the proper scope.

For instance, I found two entries...  Here is SEARCH RESULT ONE:

It's just $44.95 and comes with a box of minerals.  It MIGHT be the most recent SMD-09; but, before ordering I would send the vendor a note requesting verification.  Here's why.

Possible SMD-09

 Notice the little button just in front of the microscope's riser?  That is no longer the light switch for the most recent version.  It may be that the vendor did not have an image of the most recent SMD-09 version and simply used the image of the prior version of the My First Lab Stereo Scope.  If that is the only reason for the discrepancy, it is a great bargain at only $44.95 with Prime shipping.  The ad DOES mention the 50x capability.  But, would still confirm that it is the one you want.

SEARCH RESULT #2 is a bit more expensiv, at $69.99; but, it DOES have the image of the correct scope.

SMDZ -09 - Correct Image
Notice that there is no button switch in fron of the rise.  The rocker-type light switch is to the right of the base.  You can buy this one with confidence that it is the latest WOW SMD-09 scope.

 WHY I CONTINUE TO ENCOURAGE BUYING THIS SCOPE

There is a reason why I keep encouraging my readers to invest in a low-power stereo microscope for themselves and their children.  It grows our brains.  Every time you use a microscope of ANY type, you see something entirely new and every new experience that we and our children have adds new molecular structure to our brains.  I am convinced that the reason my granddaughter is planning to go to a school like Johns Hopkins is, in part, because she was exposed at an early age to the very first version of this particular scope and has used it year after year to examine bugs, flowers, stuffed toys and a whole host of other things she wanted examine more closely.

Conversely, I am convinced that many of the inherently bright, young at-risk and dropped out students with whom I work now were denied those mind expanding opportunities at an early age.  They had little opportunity to grow new connections that a microscope like this in their homes that would have provided that brain growing stimulation.

It dawns on me that all of us might have an opportunity during the holidays to donate something to a toy drive for Christmas.  Think about the SMD-09 when considering a donation.  Help grow a brain!
