How to Wear a Cabochon with an Irregular Shape

WP-White-Bar-550x10

Now that members have made a bunch of fused glass cabochons this week, what can we do with them? You can make several cabochons and mount them on your own Medieval style gemstone covered book, hot glue it onto your stapler at work and really establish that one is yours, make some really shiny refrigerator magnets but jewelry is the most common application.

I encased my cabochon in a mount by free form hand weaving seed beads. This piece used different stitches and a strong nylon mono-filament thread. The beads are 11/0 size Czech glass and 15/0 size Japanese Miyuki glass. I encased the whole cabochon because the back of the fused glass was rough and uneven.

Other methods to make jewelry with a cabochon with an irregular shape are:

  • You can stitch bead embroidery around the cabochon securing it onto a backing of leather or heavy fabric. This will be similar to my example but simpler in its execution.
  • Glue on a bar pin back to wear it as a pin.
  • Glue on a bail to wear it on a chain or cord. There are many colors, sizes and shapes of ready made jewelry bails.
  • Wire wrap the cabochon with jewelry wire.

Given the resources we have at the space, someone could even 3D print a setting for their piece and then cast it in metal!

The Joy of Melting Glass in a Microwave Oven

WP-White-Bar-550x10

Samuel and Sylvia Sion brought in to last night’s member meeting an amazing impromptu class on fused glass. Glass usually has melting points higher than metal, yet there are these new miniature kilns that work inside of a conventional microwave oven! This makes fused glass work far more accessible and affordable from past days of using a larger plug-in electric kiln for hours. The time to melt an art glass cabochon was usually under five minutes with about 45 minutes needed for cooling. The larger kiln fit several pieces at once.

The microwave being used for glass fusing needs to be dedicated to art use only and never used for food again. (Cadmium and other pigments used for colorants are toxic, so this is a needed safety precaution.) Care needs to be taken to not overheat the microwave and destroy it, so letting the door stand open and the unit cool off between rounds of fusing glass is needed. Also, microwave kiln shelf paper needs to be placed on the base of the kiln to keep glass from melting onto the surface the kiln and destroying it. Heavy weight welding gloves worked as oven mitts to transfer hot kilns and the kilns rested safely on our ceramic fire bricks to cool.

Glass specifically made for fusing needs to be used for projects, like the brightly colored Dichroic glass example I made below. Dichroic and fusing glasses are the shiny, beautiful art glass pieces you always see in jewelry at art fairs. The price for making them yourself is very reasonable with this new method; you can buy enough to make several pieces for $20-$30. The kilns and tools to get started are being added to the small metals area and will be available within the following weeks.

WP-White-Bar-550x10

People trickled in through the evening and participated in events for our 7th Birthday Party last weekend! Grilled meats, snacks and vegan pizza were served up to the mingling masses. Lockpicking with TOOOL.us went down, a group mural went up, games were played, dyes went into fabric and a familiar face returned to our space…

Art Therapy for Those with Limited Mobility

NERP is not exclusively Raspberry Pi, the small computer and embedded systems interest group at Pumping Station:One in Chicago. NERP meets every other Monday at 7pm at Pumping Station:One, 3519 N. Elston Ave. in Chicago.

Art is one of the fundamental ways humans express themselves and it occurs in every culture going back to the beginnings of humanity. Art therapy is a valued tool that bridges the disciplines of psychology and art and has been undertaken by Iraqi war veterans, victims of violence and other traumas.

But what about individuals whose limitations prevent them from holding a paint brush or manipulating clay? Haddon Pearson is a local creative type who is working with a child psychologist from the University of Chicago to develop systems that will enable people with limited mobility to make art. He will discuss some of the technologies and ideas that they are exploring to lower the bar for people with limited agency to express themselves.

The technology we’ll visit tonight is a Makeblock plotter that will potentially serve as the motion actuator for 2-d graphical output. The plotter is not feeling well at the moment. NERP aims to fix it, but first we need to understand the hardware and software that runs it. Andy Sowa will lead a live troubleshooting and learning session with the collaboration of the NERP Meetup.

Find NERP and Pumping Station:One at
Meetup NERP-Not-Exclusively-Raspberry-Pi/
and
http://pumpingstationone.org/

Doors open at 6:30pm.
NERP is free and open to the public.

Hack a Replacement Wacom Tablet USB Cable

usb-cable-hack

 

WP-White-Bar 550x20

Did you lose the USB to USB Micro B cable that connects your Wacom pen tablet to your computer? Don’t panic! This is not necessarily another propriety piece of equipment you can only get from the manufacturer. There is a quick fix.

The cable that comes with the Wacom may alarm you to have lost it; it looks unique, since the smaller Micro B end has a 90 degree angle turn. This is a design element possibly for aesthetics and maybe to prevent the cable from pulling out easily from the tablet while it is in use. You do not need a replacement cable exactly like the one that shipped from the manufacturer. What you need is a replacement cable that fits.

This is where cable replacement gets tricky because the Micro B port on the tablet is deep and very narrow. Most cheap, off the shelf cables have both ends encased in a massive brick of rubber that will not fit the tiny 6 mm tall by 12 mm wide Wacom Micro B opening. You can take any old cable and make it fit by whittling down the rubber as close as you can to the metal. A box cutter with a sharp, new blade works well. I tried to improve the look of this hacked cable with a single wrap of electrical tape, but had to then remove the tape as that still made the Micro B end too thick to attach.

If you want a neater cable to use for the long term, beyond this DIY quick fix, step away from the cable aisle in your electronics store and head over by the cell phone accessories. The Micro B cables marketed for smartphones tend to have a sleeker design, more color choices and smaller rubber grips which will insert into the Wacom. Bring your pen tablet with to make sure the cable you select will fit before you leave the store. Also, be sure you get a combined data and charging cable, since charging only cables that look similar are usually in the mix of products for cell phones.

Woodshop @ Pumping Station: One

When I took over the Pumping Station: One wood shop (a little more than 2 years ago), I started making cutting boards as my metric on how functional the shop is. I reasoned that it’s an excellent entry level project, and most of the users of the shop would be people with no woodworking experience. The first boards I made at the space were pretty good, but every step was a chore. The jointer could never stay sharp for more than a month, the planer required weekly maintenance, dust collection was a hassle, and it took 10 minutes of setup to do jobs that should take only seconds. Well, little by little, training, equipment upgrades and accumulation, shop days, and community has made the shop much easier and safer to use. My most recent cutting board demonstrates what the shop is capable of.

Last year, one of my favorite coworkers invited me to her wedding, and I decided that I’d make her something special. After discovering the color scheme in her kitchen, I chose padauk, purpleheart, and cherry and made a design in a free cutting board design program.

cutting board

To prevent the wood from warping while in service, I milled the wood square (rectangular, really, but it’s woodworking jargon) and let it dry for two weeks in the shop.

As expected, the boards warped again as they dried. I milled them again and two weeks later, they were still square, so they were ready to glue up. After the initial glue up, I had a board that looked like the top board in the design program. I planed down one side of the glued-up board with handplanes and then ran it through the planer the board was flat. At that point, I set up the tablesaw sled to cut the board into $1 \frac{5}{16}$ inch wide strips. I created the pattern by flipping every other strip.

cut boards

After cutting the edge-joined board into strips, I glued up those strips and gave my board to a friend who ran the board through his 40 inch drum sander, to flatten down the glued up strips. My target thickness was $1 \frac{1}{4}$ inches, so I was thrilled with the $1.227$ inches that I achieved. At that point, I used a handplane to clean up the edges, and took an obligatory picture of my handplane with the produced shavings.

After getting the board milled to the desired dimensions, I set up the router table to cut handholds. After the handholds were cut, it was time to sand. And sand. And sand. And then sand a little bit more. After about 10 hours of sanding, I decided that I was going to get an angle grinder style rotary sander and handle that work in maybe an hour for all future boards. When I was content with the smoothness of the board, I soaked the board in mineral oil overnight, to seal the board against water. At the end of the soak, I wiped away as much mineral oil as I could, although the board kept bleeding mineral oil for about a day. At that point, I used a mixture of mineral oil and beeswax to seal the board and create the beautiful finish that I achieved. I applied the mixture, waited for it to haze (I waited about 90 minutes), and then wiped as much away as I could. Then I sanded using waterproof 1000 grit paper, which buffed the finish and filled in any potential gaps. Then I used a polisher to polish the board until I achieved a glassy finish. Project complete.

Knit a Working Loudspeaker

knitted speaker

I’ve been working on an embedded speaker design off and on for the last few years, and finally got around to posting an Instructable for it.

I created knitted and non-knitted versions, and am quite happy with how it turned out. The secret is using dipolar magnets and hard drive magnets are a cheap way to do this. (Plus, a really big amp.)

Props to Sache for lending her glue and paper expertise!
