Mysteries at the Museum

Wednesday, December 3rd, 2014

A male Ghost Mantis is in the following picture:

Museum worker Chris lowering the shade

At the last HOLA (or Hands On Live Animals) I was attempting to use my new magnifier app on my new smart phone to take a close-up picture of  Phyllocrania paradoxa otherwise known as a Ghost Mantis.  Just when I was getting the phone ready, the leafy looking bug decided to take off! As in fly away… He (and it was a male mantis) made a few circles at a height of about 25 feet in the air and then finally rested upon the shade near the window. He’s in the upper left of the window in the above picture but you can’t see him.

Using the zoom function of my camera (Not my smart phone) I was able to get the above shot of the little ghost while he rested on the shade. Chris got a ladder to reach the pull chord for the shade and gently lowered the little bug-a-boo so he could safely be returned to his cage. All is fine, so I thought, but when I returned to the museum the following week I found out that 1) Chris got a job a CSU and is no longer employed at the museum and 2) The females in the mantis cage ATE THE ESCAPEE ! … I guess they were a bit pissed off that he wanted some time away from the girls.

LCS Move: Part One

Monday, November 24th, 2014

Today the LCS moves in to the new space (partly)

Volunteers get stuff and bring it in through the back door

Today we opened up the new space and brought in some tools. Mostly for the wood shop: Clamps, band saws, wood lathe, sanders and carving tools.

Some of the stuff

Oh, and some routers too! The kind of routers that shape wood, not the network kind that download porn. Yes, lots of good stuff for making banjos. And other things as well.

T-Vox at LCS

Monday, November 17th, 2014

Some actual work was done at a local maker space:

Jim Z tunes his Theremin Vox

From now on, when I talk about the ‘HUB’, I mean the Fort Collins Creator Hub. If I talk about the ‘LCS’, I’m talking about the Loveland CreatorSpace.  Today was the day to tune the old Theremin. The problem with tuning this thing is that when you try to get in and turn the potentiometer in the circuit, just ‘being there’ changes the sound envelope and that can be very annoying. Good thing nobody was at the LCS today because I would have annoyed anyone within 200 feet of the damn thing. The idea was to make some sort of remote tuner that would not interfere with the Theremin circuitry; with a piece of plastic coat hanger no less.

Note the rubber sculls are still attached since the last time I took this puppy out to play!

The “HUB” visits FoCo Science Guy

Saturday, November 15th, 2014

Special show today at Science Toy Magic in Old Town Fort Collins:

Matt shows off some of his toys

Which could be boomerangs or gyroscopes or radiometers; Included with this performance is a detailed explanation of how it all works. That’s the real show at this magic store: You learn about physics and you like it.

If you see people looking down a copper tube…

It must be a demonstration of Lenz’s Law. The ‘Law’ says that any induced electromotive force will create a current whose magnetic field opposes the magnetic flux from the original induction. It kinda shows how electromagnetic circuits obey Isaac Newton’s ‘Third Law’, com’ on, you know this one: For every action there’s an equal and opposite reaction.

Science Time at Avo’s

Friday, November 7th, 2014

No music this time:

Women of science

From left to right: Dr. Gillian Bowser, Natural Resource Ecology Laboaratory, CSU; Dr. Emily Fischer, Department of Atmospheric Science, CSU;Dr. Sara Rathburn, Warner College of Natural Resources, CSU; and Dr. Paula Cushing, Curator, Denver Museum of Nature and Science.

This working group on Women, Population and the Environment offered the public a speaker series titled, “Exploring the Influence of Gender in Science and the Environment” We had to come because Dr. Cushing is an arachnologist who helped revise Spiders of North America: An identification manual. She had to sign my copy!   Lots of young women science majors in attendance, none of them spider doctors.

Sponsored by:  Women’s Services and Gender Resources, School of Global Environmental Sustainability, National he Renewable Energy Laboratory, and Ripple Effect.

Day of the DEAD HEAD

Friday, October 31st, 2014

Happy Halloween!

Halloween as usual at our house

These are ‘Day of the Dead’ carnival heads. Want to know how to make them? Find out here! Go ahead, do it. It’s not that hard. And it’s cheap too.

So, what do YOU do with an exercise ball?

Our next door neighbors took a one month vacation and they didn’t have time to cancel their morning paper. They told us to just recycle it for them. Our local paper is usually not worth the time to read so instead of throwing the crap into the recycle bin, why not make something out of it. Like maybe a giant head made out of Papier-mâché using an exercise ball as the form? As seen in the above picture we have some paper and a large ball. If you don’t know how to make Papier-mâché, just look it up on the internet someplace.

What to do with a giant paper ball?

1) The big ball can be manipulated in a number of ways and other paper parts can be added to make the desired head topography. 2) If you want to wear this thing on your head, you should use some kind of device to keep it firmly seated on your head so the headpiece does not flop around. I used a skateboard helmet I bought at the Habitat resale store for $2. A helmet with a hard plastic shell works best; that way you can bolt some heavy cardboard struts to it and attach the struts to the inside of the giant ball.  3) With the helmet in place, try the head on for size. I stood in front of the bathroom mirror and poked a small hole where I thought might be the best height for an eye-hole. From there I made a sample mouth and tested to see if I could see where I was going via the mouth slit. 4) If the mouth slit works, then it’s time to paint the head. I had some left-over white interior house paint that worked quite well.

Giant Heads, Version 1.0 and maybe even version 1.1

At first we thought our costumed idea might be some kind of bi-polar Jack Skellington character but we didn’t have time to work out the rest of the outfit. While looking through our vast collection of stuff we found two bright yellow contamination jumpsuits that might work. At least if we couldn’t see the cars in the street due to our obstructed vision maybe the drivers of those cars would see us?

Beta testing and advertising

1) Going out into the real world could be scary. A week before Halloween the City of Fort Collins had something called a Zombie Fest so we thought it would be a good idea to try out the version 1.0 heads while walking though Old Town. The test basically was an obstacle course of streets, curbs, stores, zombies, bushes, etc. and we learned two things from the experience: First we were a BIG HIT with the zombies (I assume they though there would be GIANT BRAINS in those heads?) and second we needed to make the mouths at least three times larger so we could see where we were going! 2) With the new and improved version 2 head I made a quick visit to the spooky family event at Laughing Buck Farm to see if I could walk around small children and barn animals– Seemed to work well! 3) The front of the face of Version 2 where we turned version 1 into a Dia De Los Muertos carnival costume.  4) On the back, some reference to my ‘homies’ at the local hacker spaces: The FCCH that looks like the structural formula for Fluoroacetylene is for the Fort Collins Creator Hub and the LCS is for the Loveland Creator Space.

Sustain*A*Hillbilly Faire

Friday, October 10th, 2014

Or was that the 15th annual Sustainable Living Fair?

On display, A Tesla Model S EV

Yes, on display only. I volunteered to drive/co-pilot the Electric Vehicles (EV) at this year’s fair. I test drove a Nissan Leaf, Chevy Volt and Mitsubisho MiEV, but NOT THE TESLA. Maybe next year?

It gets better: Finnders and Youngberg on the Main Stage

and a giant chess set made out of junk

Spark Girls and more

This weekend: The Northern Colorado Mini Maker Fair:

Including Welding

I was representing The Fort Collins Creator Hub and the Loveleand Creator Space at the show.  I was also gathering digital video with the intention of editing the mass of data into some kind of presentable package for the Public Access Network, and who knows, I may be finished by 2016.

ILLUTRON!

Monday, September 15th, 2014

Right! I was in Copenhagen and I had to see this for myself:

The Illutron

It’s a collaborative art / maker space studio on a ship. Well, OK, it is sort of an old cable laying barge, a floating hacker platform, a rusting work of watery art, but very unique. From Copenhagen Central Station take Bus 40 toward Refshaleoen then walk a bit north and ask where the hippies live out on a barge.

Very Ship Like

With plenty of booty just lying about; aft ye might  find woodworking tools and perhaps ye olde X-Y cutting table midships. Electronics projects be lyin in the hold.

But wait, there’s more

Above deck is a LP twin cannon that can shoot 20 foot diameter donuts of fire and an LED display for those seeking the ship at night (perhaps when the donut machine ain’t working).  Included in the more than 8000 Sq.Ft. of space one might find a conference room and a party deck.

Lots of junk, but it’s all good junk

In one corner sits an ABB industrial robot and in another some sort of left-over controller for the cable rigging (so I was told) and aft on the port side a white cylinder resembling an orgasmatron (ref: Woody Alan’s Sleeper ) . Looking out the hatch in the direction west one might see ‘Den Lille Havfrue’ i.e., The Little Mermaid statue, that is if you had a telescope or an extremely powerful telephoto lens.

Lots of things to play with…

They said that they recently moved the barge to its present location so it’s a bit messy. They also mentioned they had an art installation at Burning Man. Burning Man! Like in the Nevada Black Rock desert, US of A? Wow! These guys are good.

Solid State

Monday, August 25th, 2014

Yet another Hacker Space

It’s the SSD

or the Solid State Depot and their domain name is BOULDERHACKERSPACE.COM. Founded in 2010, the group is well organized and have over 500 members on MeetUp (although the actual paid membership is lower)

Solid State Fun!

Probably not called the Boulder Hacker Space due to the bad press that the term HACKER gets these days, I was not sure from talking to the members why it was called a depot that is Solid State. From a purely electronics viewpoint there should be no relays or vacuum tubes in the depot; I’m sure like most spaces, the original founders were electronic geeks who hacked only transistors and IC’s.  Tubes and relays are cool too, but the Vacuum Tube Depot sounds more like a place for vintage radio buffs or maybe a place to get your vacuum tube on like the Tube Depot.
