Audio Files and Photos from my Midwest Furfest Speaking Panels!

Posted by: The Mad Scientist

Ahoy to all of you Foxee fans out there! While I am a few weeks late with getting this information up onto my blog, I have finally sifted through the many hours of audio that I recorded during the Midwest Furfest furry convention, and I have separated and MP3-encoded some sound clips of my best speaking parts during the panels that I was a panelist on for you to listen to! In case you don't remember, last November at the Midwest Furfest furry convention in Schaumburg, Illinois I was a panelist on three speaking panels that had to do with both animatronics and fursuit (animal mascot) costume construction. I was asked to be on the panels to answer questions about animatronics and electronics and their uses in fursuit costumes. While I have never built a fursuit personally, my Foxee animatronic robot project involves many of the same building skills and techniques that an animatronic fursuit does, so I was still very useful as a panelist despite my relative inexperience with the panels' topics.!

I spoke on three panels at the convention, the Fursuit Mega Construction Panels 1 and 2, and the Fursuit Head Construction Panel. For the two Fursuit Mega Construction Panels I was teamed up with Michael "Aeto" Sawyer who has been speaking on this panel for the last 5 years and did most of the talking, and Jason "Ocicat" Williams, a commercial artist and a fursuiter for the last 5 years. On the Fursuit Head Construction Panel both Aeto and Ocicat returned as panelists and this time were joined by Kitt Foxx, a former Disney Animator and Hollywood Special Effects Technician. Kitt Foxx is the extremely talented person who designed the animatronic Georgia Belle fursuit that utterly amazed me at last year's Midwest Furfest convention and inspired me to do my own animatronics project. He has been a fantastic help to me with getting my own project off of the ground to the point of being my mentor, and I was very honored to be speaking on a panel with him!

Since my experience on these topics paled in comparison to that of the other panelists, my plan for my speaking part of the panel was to give the audience a very basic introduction to what servo motors were and how they worked, how to build some basic servo driver boards using a variable width pulse modulator to control them, and what information was available for beginners on the Internet to help you get started. I brought is several props for my presentation, including a working servo driver board hooked up to a Futaba servo motor and a nickel cadmium battery, a homebrew servo tester board that could hook up a servo motor to a Commodore 64 microcomputer to test its range of motion, and several books on robotics, animatronics, and microcontrollers.

I also brought in some photographs of what the output signal of a servo driver board looked like displayed on an oscilloscope so that people could see first-hand what the signals that controlled servo motors looked like. Some of the topics covered by the other panelists on these panels included using fiberglass to construct fursuit heads, how to choose the right fur for your costume and sew it together, how to airbrush patterns onto fur using leather dyes, how to use foam for sculpting fursuit body parts, how to use electric fans in fursuit heads, how to choose the right fursuit eyes and teeth, how to make fursuit tails that keep their shape using a Delrin rod for support, how to give a convincing performance while wearing a fursuit, and much much more!

The Audio Files

I originally wanted to post my audio recordings of the three fursuit construction panels in their entirety to my animatronics blog because of how interesting and informative they were, but unfortunately that was against the Midwest Furfest audio and video recording policies and I was unable to get permission from the convention staff to do so. So the very best that I can do is post some short audio clips of some of the better things that I talked about and explained during the three panels.

Please judge my speaking performances kindly if you decide to listen to my audio clips from my Midwest Furfest panels. As the sole representative of my company, Project Destiny Studios, at the convention, I found myself spending long hours working on setting up and tearing down my artwork at the art show and auction, staying out late selling artwork as a dealer in the "Artists' Alley," and pulling near all-nighters to prepare my panel presentations for the next day. I far overstretched myself and pushed myself past my limits by trying to do so much on my own at the convention, and ended up only getting 2 hours of sleep before my Saturday 10:00AM panel and only 45-minutes of sleep before my Sunday 9:00AM panel because of it. So if I sound like I am half out of my mind while I am giving my presentations in these recordings, thatis because I probably am! Luckily, since I am a mad scientist, I am supposed to sound half out of my mind most of the time, so it all worked out!

Me Introducing Myself to the Audience During Saturday's Fursuit Construction Mega Panel 1

This short audio clip features me introducing myself as "Hoagiebot" to the panel's audience. At furry conventions it is standard practice to have a nickname on your convention badge, and that is what everyone addresses you by. For most furry convention attendees their nickname is the name of their furry "fursona" that they enjoy dressing up as at the convention, much like how someone who enjoys dressing up as a Klingon at a Science Fiction convention would have a Klingon name on their convention badge. In my case, Hoagiebot is just my user name on several online auction sites and Internet services and has no real significance after that. At the same time however it is the nickname that most people in the furry community would recognize me by, which is why I used it at the convention. I also tell about myself and my Foxee animatronic robot project during this introduction, and crack a few sleep-deprivation inspired jokes while I'm at it!

Me Giving my Presentation on Using Servo Motors for Beginners during Sunday's Fursuit Head Construction Panel

In this audio clip I start off by reflecting on my own experiences while trying to learn how to build animatronics on my own during the dark days before I had met Kitt Foxx and had only myself to rely on to figure things out. I explain how you can use general purpose "Battlebots" style robotics books to learn how to create animatronics because the same methods used to make hexapod walking battlebot robots move are also employed in making animatronic robots move their various parts.

I then go on to talk about two websites that I found to be extremely helpful when I first started out learning about servo motors and how that worked. Two websites provided schematics for different simple variable width pulse modulator servo motor driver boards, and I ended up constructing both designs for comparison. The first website that gives a good overview on servo motors and there use in fursuits is the Fursuit FAQ at You can find their schematic for a servo motor driver board here:

The second website mentioned in my presentation is Fox's Electronics, which has a better servo driver board schematic and photos of what the finished driver board looks like. The servo driver board that I demonstrate during the presentation is modified version of his design. You can see the Fox's Electronics website here:

This photo shows the pulsed output of a 555 Timer IC based Servo Motor Driver Board shown on my Hewlett Packard Model 130BR Oscilloscope. Most servo motors respond to pulsed signals that are between 1KHz and 2KHz. As the oscilloscope shows, this servo driver board is currently sending out a pulse at 2.050KHz, which is causing the Futaba servo motor that is hooked up to it to turn all the way to the right and hold there. You can find the schematics for this servo driver board at Fox's Electronics.

Here is a triangle wave signal from a function generator that is being outputted on an oscilloscope for comparison.
This photo shows a triangle wave signal at 4.005KHz that is being output from my Exact Electronics Type 240 Function Generator into my Hewlett Packard Model 130BR Oscilloscope. This photo is shown as a general comparison to the servo driver signal. (Hey, I know that this is not the greatest of comparisons, but I had to have some excuse to try out my new function generator!)

Me Answering an Audience Member's Question About Powering Battery-Powered Fans During Sunday's Fursuit Head Construction Panel

This audio clip starts out with an audience member asking about how he can find a more reliable power source than a 9-Volt battery to power the battery powered fans that ventilate his fursuit costume's headpiece. The question is started to be answered by Aeto who recommends using a RC battery to power the fans, but cautions about the overheating dangers caused by this. Having solved this kind of problem before, I then add in that you can readily build a simple regulated power supply out of a 78XX series voltage regulator IC and 3 capacitors that can be used to step down the voltage from the battery to the fan and prevent the fan from overheating. The "XX" in the voltage regulator IC's model number is the desired voltage that you want to regulate the battery's voltage at. For example, if you want to take the current from a 12-Volt battery and regulate it down to 9-Volts, you would use a 7809 voltage regulator IC. You can find the schematics to build such a regulated power supply at this website here:

Kitt Foxx then talks about the advantages of using 12-Volt personal computer case fans in fursuit heads and then either running them at voltage with a 12-volt battery pack or running them under voltage with a typical 9.2-Volt RC battery pack. 9.2-Volt RC battery packs are advantageous because they are extremely common and can be found at nearly any local hobby shop or Radio Shack store. Since it is then discussed that battery voltages can drop over time, I once again add in that you can use a simple regulated power supply board to keep the voltage level going to your fans constant.

While I did do a lot more speaking on the panels than just the three audio clips presented here, these were the things that I said that are the most interesting on their own and out of the context of the panel presentations in their entirety. Being a rookie panelist among several experts in the field that had each done several of these kinds of panels before, I wasn't able to contribute quite as much to the presentations as I originally thought I would be, but then again I was brought on as an extra knowledgeable person to support the others and not to be a primary presenter at the panels. Because of this, I feel that I fulfilled my role on the panels with flying colors, especially when I was able to help answer that one audience member's question about powering fans by explaining how he could easily build a regulated power supply from parts that can be bought for a few bucks at any neighborhood Radio Shack store.

I am sure that eventually down the road once I finally get my little animatronic arctic blue fox completed and performing shows that will eventually get an animatronics panel of my own at conventions, and then I will be able to show people how much fun it can be to be able to create your own robotic creations. These Midwest Furfest panels were just getting my feet wet for a bigger and brighter things to come, and I was more than happy to be a part of them!

In any case, I very much hope that you enjoyed all of these audio clips that I recorded and encoded for you, and that you found them to be helpful and informative! As always, comments are welcomed and encouraged and I would absolutely love to hear what you think!

I Will Be Speaking On Three Midwest Furfest Panels!

Posted by: The Mad Scientist

I will be a panelist speaking on three fursuit construction panels at the Midwest Furfest Furry Convention! The convention takes at the Hyatt Regency Woodfield Hotel in Schaumburg, Illinois, from November 18-20. If you are attending the convention, you can see me speak on the following panels at the following rooms and times:

Fursuit Construction MEGA-Panel 1
Saturday, November 19th, Arlington Heights Room, 10:00AM - 12:00PM

Fursuits, those wild and zany animated fuzzy critters no furry can resist! So how do they come to life, and what does it REALLY take to make one? Here you can learn, from some of the best builders in the fandom, about designing, constructing, and caring for fursuits. Whether it's your first suit or your tenth, you're sure to learn some valuable tips and techniques! This first session of two MEGA-panels will cover basic fursuit construction and design.

Basic Fursuit Head Construction
Sunday, November 20th, Schaumburg Room, 9:00AM - 10:00AM

Ok, so you've almost built that fantastic fursuit, but something just doesn't seem right! Join Ocicat as he discusses basic fursuit head construction and materials that will help you top off that perfect suit, and bring your critter to life!

Fursuit Construction MEGA-Panel 2
Sunday, November 20th, Schaumburg Room, 10:00AM - 12:00PM

As if we haven't had enough fun, already! Stop on by for more furry construction mayhem as fursuit builders discuss advanced fursuit building techniques, materials, special effects, and basic care and maintenance.

(Midwest Furfest panel descriptions were taken from the Midwest Furfest website.)

To explain how I became a panelist on these panels, some time ago I mentioned my Foxee Animatronics Project and my experience with servo motors and electronics to the Programming Director for the Midwest Furfest furry convention. I knew that the convention often had an animatronics for fursuits panel each year, and I offered to help speak on the panel if I was needed. For those of you that are unfamiliar with the furry fandom, a "fursuit" is a sports mascot-style animal costume with a full body suit and an animal head that you put on over your own. Just like how Star Trek fans dress up like Klingons and Fantasy Fans will dress up like a mage, furry fans like to dress up as "furries," which are upright walking animals with human personalities like Bugs Bunny or the characters from the Walt Disney animated feature film "Robin Hood." Dressing up into character is just a fun way to "role play" as something that you always wished you could be.

Getting back to the story, while I was told by the Midwest Furfest Programming Director that I wasn't needed to speak on the animatronics panel, the programming director did ask me to speak on three other fursuit construction panels at the convention to answer any electronics questions that the audience may have. These panels include the two fursuit construction mega panels, and the Basic Fursuit Head Construction panel. At first I was a little intimidated by the fact that I was going to be on a fursuit head construction panel considering that I have yet to construct any fursuit heads myself. I expressed my concerns to the Programming Director, but she reassured me and told me that I was placed on the panel to field any electronics or animatronics questions that the audience would come up with and to back up the other panelists if I had something to add to what they were talking about.

With that concern out of the way, now all I have to figure out is how I am going to get up at 9:00AM on Sunday morning-- Considering the fact that this Mad Scientist is nocturnal and plans to be dancing the night away with all of the cute ladyfurs during the Saturday night dance, it is going to take at least three-quarters of the caffeine in the northern hemisphere injected straight into my heart to get me up by then! A Mad Scientist's work is never done! Despite the fact that I will probably be resembling one of my undead zombie experiments when I am at these panels that early in the morning, it should still be a lot of fun! And while I don't know the possibility of this yet, I might just be able to bring in an oscilloscope and hook up some servo motor controller boards to it to give a demonstration about how servo motors work. We'll just have to wait and see!
