Making the Hivelord [Part 2]

IMG_0544

It’s been a while, but here’s the second post on making the Hivelord. This post will focus on the frame of the Hivelord mask, which is mostly made of copper tubing and scrap wood. Unfortunately this means it is relatively heavy for something mounted around my head, but I found a military external frame backpack that works well to transfer the weight to my hips. The length of the mask helps balance it over the frame, and I added an adjustable strap to the back to hold the laptop screen in the right position in front of my face. The end result is surprisingly comfortable!

To start, check out those copper tubes. This may have been the most expensive part of the project, I spent around $60 on copper tubing. I bought a few lengths from Home Depot, cut them into fourths, and then hammered the ends flat. You can also squish the ends in a vice to flatten them, but hammering it was a lot more fun. Once the end was flat, I carefully used the drill press to put a hole in them, then bent the end to an appropriate angle. Use a vice to hold the flat part while you bend it. I used some spare nuts and bolts to hold the copper tubing to the wood part of the frame.

Here’s the mount for the screen. The backside of the repurposed laptop screen sits on those wooden blocks, which are glued to the wooden board. I drilled those holes in the block and then hot glued the nuts inside them so you can tighten the bolts into place with the screen installed on the front. There’s enough space between the laptop screen and the mounting board to house the screen converter. I was originally going to put a camera on the inside to project my face onto the screen, so I designed the mask to be around 9 inches in front of my face.

Here I am making sure my head fits in there.

Now, to attach the screen. I had some scrap copper tubing left over, so I made some custom brackets to hold the screen in place. Flatten the tube with a hammer and bend it in the vice. Hit the bend with the hammer a few times to express yourself and give the bracket a nice 90 degree angle. I pretty much made these up as a went along, marking where the bend had to be and then making it in the vice.

The whole thing is held onto the backpack frame with a few zip ties. I was originally just testing it out with the zip ties, but they worked so well I kept them there. You can see a metal wire coming down from the back mount board. That was replaced with a backpack style strap, allowing me to adjust whether the head is looking down or up and counterbalance the mask.

Here’s the periscope. It took me a few beers to convince myself that this would be a good idea, but I was surprised at how well it works. It’s made entirely out of hot glue, square dowel rods, two mirrors, and some math. If I had to make it again I’d make the mirrors a little larger, you can only really see out of it with one eye.

Next I tested out the electronics. The screen was upside down but that was simple enough to change in the raspi. I mounted the electronics to the wood board behind the laptop screen. It’s always been a wonder to me what’s the best way to mount electronics to a solid surface. This time around I penciled in where the mounting holes were on the pcb, then I drilled some pilot holes in these spots. A dab of hot glue held the boards in place as I put in screws and or wood nails through the pilot holes. Of course, most of these stuck out the other side of the board, so I used the dremel to cut off the pointy ends. In the end it was pretty solid but the process was a bit nerve wracking.

Last but not least I had to cover up the sides of the frame. I found some scrap foam board, cut them out to size, and then spray painted the panels orange. They are held to the frame with EL wire threaded through the foam board, with the copper tube in between. I marked every half inch, then used the drill press to make some clean holes in the foam board. It took a while to thread the wire though, but I was amazed that each side required exactly 15 feet of EL wire. Sometimes you luck out when wingin it.

Thanks for reading. Next up will be a post on the Boomfists I designed for the Hivelord; speakers attached to my fists. They haven’t made a public appearance yet, but chances are high they will make an appearance with the rest of the costume at MAGFest in January!

 

Humanity reached a big milestone this year. For millions of years, every tool that homo sapiens has ever made has had one thing in common: it was made on Earth.

3D printer and MSG

The first 3D printer in space from Made in Space

But this year we successfully launched a 3D printer into space, marking the first time in human history that we can make an object off the surface of the earth. The group that has made this possible (besides NASA) is Made in Space, a company founded to prove that off-world additive manufacturing is both possible and the next step in space colonization. I talked with Made in Space co-founder Mike Chen about the future of making in space.

Getting to space is getting easier each year, but even with the new SpaceX Dragon missions, the cost of putting a kilogram of mass on the International Space Station is still about US$22,000. That makes it unreachable for most of us. In 2010 Made in Space saw a chance to disrupt this rocket-powered supply chain and enable manufacturing in space using newly available consumer 3D printer technology. They ran countless tests of existing consumer 3D printers onboard a reduced gravity aircraft (aka the Vomit Comet) to find a suitable design. Mike explained the problem, “We actually get a few emails a week [where] someone takes a printer and turns it upside down or sideways and says, ‘See? This prints upside down, so why wouldn’t this printer work in space?’ You know, you’re just not really thinking it through. Gravity is still there, acting as a force to hold things in place.” Remove that force and everything starts to oscillate. Also, heating elements in microgravity are difficult because there is no natural convection to circulate hot air, making passive cooling nearly impossible. The machine also needs to withstand the violence of launch, which may be the biggest build challenge. The Made in Space team decided that they needed a design of their own.

Mike says that’s one of the reasons the space stations exists, to experiment with how different systems act in micro-gravity. This is very much an experiment and is being treated as such. On November 17th, the printer was installed in the Microgravity Science Glovebox (MSG), a facility on the ISS dedicated to possibly harmful experiments, and a perfect place to safely test new technologies. Now that the machine is ready, the first extraterrestrial manufacturing will commence soon.

I pressed Mike for some details on the machine itself. It’s a Material Extrusion machine like most consumer 3D printers on the market. That means it’s full of steppers; everyone loves steppers. In order to limit their unknown variables, they decided to use ABS plastic as their material. It’s one of the most well known polymers and is a very useful material. ABS does have toxic offgassing, so in addition to being housed in the MSG, there are environmental filters to protect the astronauts’ precious atmosphere. A 3D printing professional will also appreciate these simple design guidelines presented by Future Engineers who host a challenge to inspire schoolkids to design an object to be printed in space. Those guidelines also call out the build volume of 5cm x 10cm x 5cm and specific design hazards posed to an astronaut. Printed parts must not have any support structures or require post processing, which could release small particles in the air that can get in everything, including the astronauts. The standard 45° overhang is present as well. Maybe the next machine will be a 5 axis robot that can follow clever 3D toolpaths and truly print any geometry.

This machine has been designed with multiple design constraints to contend with. These constraints really drove Made in Space to develop their own machine and IP. On the ISS, an hour of an astronaut’s precious time will cost about $50,000. That means no fiddling with extruder tensions or babysitting the machine as it prints. So the printer only has one button, the ON button. Everything else is handled from ground control thanks to the MSG’s video cameras.

The big question is, what will they print first? Made in Space is being very secretive about this, but we won’t have to wait long to find out. The first print will be a special milestone, but subsequent prints will be test coupons that can be compared to prints made in an identical machine on terra firma. After proving the printer’s quality, there is a long list of useful objects that are needed on the ISS. There are hundreds of replacement parts already in storage on the station, but in the future those parts will be made on demand. At that point each kilo of printer material becomes a lot more valuable and versatile. There is even new opportunities to improve the lives of the astronauts by allowing family members to send digital gifts into orbit. In 2009 Randy Bresnik’s daughter was born while he was on an ISS mission. Imagine in addition to a photograph, Randy holding a 3D print of the newest Bresnik while passing out bubblegum cigars to his fellow astronauts.

You too can design something to be produced in space. Mike was keen on energizing the thousands of brand new 3D designers in the world to help solve problems in space. This machine gives an amazing amount of access to the 3D printing community on Earth. Made in Space is very receptive to ideas about what should be manufactured in space. Reach out and find a novel solution to a unique problem and there may even be a commercial benefit in it for you. See what Made in Space is doing on their website and follow Mike Chen on twitter: @MikeChen. These are exciting days.

I heard there were smoothies here?

Salutations, flatlanders! Your electron based mail message reached my hyper-dimensional lair, I was lured out of the 67th dimension by word of snacks, refreshments, and of course, your attempts to augment your meaty forms with your so called ‘technology.’ The idea: to design artifacts made 50 years in your future. How will they affect the fragile social human construct? More specifically, are these items you’re designing to simplify and enhance your lives creating one step forward in the inevitable march toward a dystopian hellscape? I’d answer these questions, but I’m technically not allowed to break causality.

But I digress, I’m really here to show you all the souls I stole pictures I took with my face. It only took a few years off your lifespan, and there’s a 50/50 chance they were bad years anyway. Thanks for being such good sports!

Making the Hivelord [Part 1]

Oh hai

Hello, meatbags! Perhaps you saw me at Maker Faire, jukin and jivin and havin a time. You probably wondered “where did this guy get his slick get-up?” And,  “is it possible for me to build something similar in his glorious image?” And then your dreams were consumed each night by a vivid nightmare of a distant planet, covered in entirely in evergreen trees and a deafening roar. “What is this place, and why am I forced to wander it every night?” No? Well consider yourself one of the lucky ones then.

Anyway, this is part one of the build log for the Hivelord costume. The inspiration was based on the scramblesuit from the novel A Scanner Darkly, by Philip K Dick, which is a suit that anonymizes its user by constantly projecting a changing image of different people on the outside of the suit. I figured that’s not technologically feasible, but making a mask version certainly is. I originally wanted to record short videos of the inside of the mask, with different people wearing it, but as I built the mask it became obvious that it wouldn’t be feasible, or as cool as using it to take photos. There is a raspberry pi running some python code to control the slideshow and picture taking functions along with an arcade button connected to the raspi’s GPIO. Pressing the button puts the screen into preview mode, which shows what the camera is looking at. When the button is released, the picture is taken and added to the slideshow.

Parts list:

  • raspberry pi with camera
  • old laptop screen
  • output converter for the laptop screen
  • arcade style button
  • 12V lead acid battery
  • 5V step down converter (for raspi)
  • HDMI cable
  • military backpack frame
  • copper pipe
  • pipe insulation for padding
  • various nuts and bolts
  • mirror for periscope
  • scrap wood, square dowel
  • orange spandex suit

This first post will focus on creating the screen. I was surprised to find many vendors on ebay selling boards that will convert the proprietary pinout of the laptop board to something useful, such as HDMI or VGA. If you have an old screen laying around, you can even make a new monitor for yourself for $35.

Found an old laptop screen in the hackerspace

Take the case off the screen and read the model number from the back. Look around on ebay for a converter board. It seems like most of them are made to order, so if you don’t find a listing, try contacting a seller. Below is a picture of the board I used, which runs off 12V. Thankfully I found a 12V wall wart in the space to test it.

The deconstructed screen

The screen connector. This will be converted to something useful, like HDMI.

The converter board came with all its own cables and its own separate board to control the screen functions, like resolution, alignment, and an on/off button.

Here’s the pic from the ebay listing. Nifty!

Once everything is plugged in, turn it on to test it out. The screen worked perfectly, and automatically configured itself to the correct resolution. There was enough cabling for me to run the wires outside of the original laptop screen case, so I just put everything back the way it was, with the converter board hanging off. All the electronics will eventually be mounted to the wooden frame of the mask.

IMG_20140729_191420706

First try running the screen.

Next, connect everything together, screen to converter to raspi, and power it up. Here I am testing out the camera after I changed all the settings to portrait mode.

The creator’s visage!

I then connected it all to a bench supply so I could see how much power the whole set up consumed. It uses just about an amp at 12v. I found a 7 amp-hour 12V lead acid battery on amazon that did a decent job, though I’d probably buy a spare since I did run out of battery at maker faire. There’s a 5V downcoverter thrown in there too, to power the raspberry pi off the 12V supply.

Thanks for reading! Next post will be on the making of the frame.

"Look at these loud suitcases I made!"

“Look at these loud boxes I made!”

On Wednesday, July 30, our friend and co-founder Brendan Schrader died of a cardiac issue. Brendan had lived with Wolff–Parkinson–White syndrome his whole life with occasional visits to the ER with a racing heart. On Wednesday complications from this syndrome took him from us. He is survived by his loving partner Elana, his mother Mary, and hundreds of family and friends. Details of the funeral service on Tuesday can be found on his obituary page. You can sign and read a guestbook there too with some wonderful sentiments.

Hive76 s a family in many ways, and that made Brendan the dad. He was a driving force in our hackerspace by pushing members to make awesome projects, sharing his knowledge with anyone that visited, and brightening the space with his unconventional sense of humor. In his honor, we will continue to live up to our motto: Make Things Awesome, Make Awesome Things! We hope you will as well.

We love you Brendan, and we miss you.


 

We had a lot of fun yesterday building a Time Machine with Pafa’s Art Summer Camp. The kids helped us add lots of awesome features like an Ejection button for Time Warp Emergencies. Also, who could forget invisibility and cloaking!? Thanks Pafa and Sue Liedke for having us! We had so much fun!
