Mysterio Bracers – Paper Prototype


Mysterio bracers/gauntlets model from paper
The photo to the left is my model for what I am trying to re-create. The photo on the right is my first prototype. What’s that you say, it looks like you just cut up a few pieces of paper and taped them together? Well, yes, yes I did. But I verified that they make the correct shapes, in the correct size, and soon I will cut them out of craft plywood using the same measurements. But first, I have to trick one of my graphically inclined friends into doing the circle style crosshatching. The curved hooks can not be done out of 2D material (paper/plywood) so I am making a plywood hook shape as the skeleton that I will fill out with modeling clay or plasticine to give the (8) hooks a curved 3D appearance.

Mysterio Sphere – Rim Reinforcement

As you may have guessed from this post, I spent another Saturday cutting the bottom(s) off of glass sphere(s). Yes, plural. I broke my replacement sphere before I was a quarter of the way around. This was due to one of the following reasons: 1) I had placed packing tape over the blade path, hoping to reinforce the glass. or 2) my tile saw blade holding bolt had loosened. Regardless, I cracked the sphere quite well.

So, I moved on to my backup replacement sphere (number 3 for those of you keeping track at home). I had already figured out that sharpie ink will NOT stick to glass when sprayed with water from a tile-saw, so I continued to use masking tape to mark where my cut should be on sphere number 3. I also placed packing tape on the non-cut side of the masking tape, as I was impressed with how well it had contained the breakage from sphere 2. (I plan on using packing tape to cover a large portion of the inside of the sphere (except the viewport) as a poor-man’s tempered glass substitute. )

Mysterio voice effects


I spent an hour assembling an MK171 digital voice changer kit from Ramsey Electronics for my Mysterio costume. The plan is to place the microphone on a wire inside the glass sphere with the speaker mounted outside so that I can communicate. I will probably have a head operated button inside that gives me push-to-talk capabilities. I picked the voice changer kit because I felt it would give me more options than a simple amplifier.
Although the voice changer kit only cost $15, I still have to purchase an external speaker to use with it.

Depending upon the acoustics of the sphere, I may also need a microphone outside with an earphone wire running inside to hear people talking to me.

I spent a much larger amount of money on an LED strobe light kit, which will hopefully drive flashing lights from Mysterio’s cape clasps or sphere.

Breaking the Sphere….or…travels to yuppieville

Sphere broken into multiple partsI purchased a football “Cowboy Collar” which I think will be a good way to mount and carry the glass sphere. Unfortunately, I got excited when it arrived, and put it inside the hole in my (previously cracked) sphere before I used epoxy putty to reinforce the rim. Digression: An egg is quite strong to pressure applied to the outside. To break it, you want to create a crack in the shell, and pull the crack apart. This is exactly what I did by sawing a hole in the bottom of my sphere, and then placing a (slightly compressed) cowboy collar inside of it. CREAK! The linear crack I had created when cleaning up the edge of the cut with the tile saw extended itself all the way to the other side of the sphere. At this point, I was considering switching my costume to that of Mysterio in Friendly Neighborhood Spider-Man #11-13, where his sphere gets cracked.

After searching the Internet for more glass spheres, I finally called the Pottery Barn main telephone number and was told the item (SKU number 702 1991) had been discontinued and it was not available for order over the Internet or phone. But she did mention that one of their stores still had some stock, and it turned out to be in Atlanta!

Cutting the Sphere, or, I hope Mysterio had tempered glass…

Glass sphere with hole cut outAfter ordering a tile saw and diamond blade ($80…twice the cost of my sphere! Guess I’ll have to re-tile the kitchen now…) I was able to cut the bottom off of the glass sphere that is going to serve as my Mysterio costume helmet. Once I got away from the hole at the bottom, it was quite thin (1/8″ thick) and relatively easy to cut with the diamond blade. As you can see in the picture above, the edge was a bit rough. While cleaning up the cut I did place two cracks in the sphere, which I have hopefully fixed with glass glue. (Update: the fix didn’t work.)

New electric bicycle motor mount

motor mounted over the front tire of a bicycle using PVC pipe

The simplistic motor mount I made for my electric bicycle (which consisted mostly of me bolting a motor to my wire basket and holding the basket away from the axle with a piece of PVC pipe) had been working well for five months. Until, that is, I ran over a particularly large pothole and the chain fell off. I took the hint that the PVC pipe and wire basket were not exactly up to my exacting quality standards and decided it was time to make something better.

I decided that the main problem was that my wire basket was not rigid enough, so my construction material of choice remained 3/4″ schedule 40 PVC pipe. This time I used TWO upright supports, one on either side of the axle and some C shaped metal shelf brackets bolted to my motor mount. (I also used PVC elbows and pipe to join the top of the supports.) This picture gives a good view of how the whole thing fits together. I am still using a hose clamp connecting it to my wire basket for left-to-right stability, but this produces much less stress on the basket, and a little left-to-right wiggle is unlikely to allow the chain to come off the gears.

New Years Resolution: Mysterio Costume!

Silvery glass sphere on the top of a christmas tree

One of my new year’s resolutions is to build a high quality Mysterio costume. In my opinion, the hardest part of a Mysterio costume is the silver sphere that serves as Mysterio’s helmet. Others have used a glass bowl, or tinfoil, but I was not happy with their results, and decided that I wouldn’t commit to making the costume unless I could get the sphere just right.

It’s amazing what you can buy for $48 on eBay! The image to the left is showing off my Mysterio sphere (44″ circumference, 14″ diameter) on top of a Christmas tree. The sphere is even mirrored inside, perfect for Mysterio’s helmet! It was originally an outdoor lawn ornament (reflecting ball) sold by Pottery Barn.

The only problem is that the hole in the bottom of the sphere is only about 1.5″, too small for my head! My options are clear: 1) Make a “headless horseman” type costume, where my head is actually under the costume’s “head”. 2) Find a way to cut the 1/3″ thick glass sphere! I’m trying really hard to get option two (cut the sphere!) working, as I want the costume to be in proper proportions, and besides, having my head inside of a mirrored glass sphere will be cool! (Visibility may be a problem, imagine wearing mirrored sunglasses at night.)

Low power (CPU) visualizations for MythTv / MythMusic


I recently checked out all of the music player visualizations for the MythMusic module (part of MythTV). They vary widely in CPU usage and visual appearance. I wanted the CPU to be at least 50% free to work on transcoding or commercial flagging in the background while music was playing, so I avoided the especially fancy ones. I also found that the ones that used OpenGL used small amounts of the CPU (as they offloaded much of the processing to the GPU).

Selected visualizations (good effects, but minimal CPU usage):

  • blank (83% idle, not much happening on-screen ) – This is the ultimate “low power” visualization, against which all others are measured. The fact that it takes my computer 17% of it’s CPU time to play ogg vorbis files should indicate why I’m somewhat CPU conscious.
  • Album Art (70% idle)
  • Squares (75% idle, simple but classy)
  • lv_gltest ( 40-60% idle, 3d histogram)
  • Gears (60% idle, simple)
  • lv_flower (50% idle, very nice!)
  • madspin (30-50% idle, fast and sparkly)

Here is a list of visualizations that might be worth the extra CPU hit based upon their cool visual effects:

  • BumpScope (20% idle – roving spotlight on embossed scope)
  • Goom (20% idle, space tunnel effect)
  • oinksie (0% idle, kind of cool)
  • infinite (0% idle, but looks good!)
  • corrona (0% idle, falling/flowing effects)
  • jess (0%, but very very cool!)
  • jakdaw (0% idle, psychedelic flowing water effect)

I suggest avoiding the following visualizations, as they use too much CPU for what they produce:

  • monoscope (40% idle, one red line)
  • SterioScope (30% idle, two red lines)
  • lv_scope (20% idle, white scope on black background)
  • nastyfft (20% idle, bars, almost 3d look scope) – Use lv_gltest if you like this one
  • bumpscope ( 0% idle – slightly faster movement than BumpScope, ball rolling left/right) -Use BumpScope (with capital letters) for less CPU usage, and better effects.

The following three visualizations gave me problems:

  • analyzer (crashes computer in fullscreen!)
  • Synaesthesia (40% idle, but no visible output?)
  • Spectrum (80% idle, simple spectrum scope w/ colors, looks weird in fullscreen)

Mythexport not working with mythbuntu

If you are getting ERROR: AtomicParsley type messages in your mythexport.log file, it may be because ffmpeg isn’t exporting the files correctly. One reason for this is that config’s in mythexport that have spaces in the name cause problems. The workaround reported here is to remove the old config, rename it into something that doesn’t have a space, and then re-create the user-job using the new config. (For good measure, I made sure the user-job didn’t have spaces either.) After this, be sure to re-start the mythtv backend to make your changes take effect.
