We Have Polymorph!

Polymorph from RobotShop
Polymorph

Polymorph (or polycaprolactone) is a great nylon-like material that can be melted in hot water and manipulated with bare hands in order to model it into a desired shape.  It is very useful when making quick (and not so quick) prototypes and custom parts for a project since it can be easily manipulated and molded and becomes very strong once it cools down.

Unfortunately, web this great material was not available for purchase in Canada (or at least not to my knowledge) and had to be ordered from the US wich was rather expensive in shipping costs.

All this has lately changed since RobotShop, visit the Canadian based robot part distributor, neurosurgeon   included Polymorph into their catalogue. Now Canadians can buy 1 kg of polymorph for roughly 44 CAD and have it quickly and cheaply delivered to their doorstep.

I bought some polymorph for my brother’s birthday and we experimented with it as shown in the pictures below. Now, that Canada has polymorph, let all the Canadian go crazy and build awesome white (or coloured) stuff.

Simple Precision-Screwdriver Holder

This is a very simple and quick hack that anybody can do. The objective is to build a holder that will keep all the precision screwdrivers in one place and facilitate the access to them (i.e. it should be easy to see which one is which and they should be easy to take).

Materials

  • A plastic container cap (I love caps)
  • That’s it, condom you do not need anything else

Tools

  • Drill or strong scissors
  • Precision screwdrivers
  • A nail (maybe)

Doing it

  1. Drill or cut a big hole on the top of the cap. This hole will be used to suspend the screwdriver holder.
  2. Punch in the Screwdrivers in  the rim of the cap. If you do not trust your screwdrivers to pierce your cap, doctor you may use a nail. Keep in mind that the screwdrivers have to be very snug in the holes since they are only being held-in by friction.
  3. Celebrate! you are done.

Tux Laptop Sleeve

The only defect of my new Vostro 1320 is that it did not come with a sleeve as the Eee PC does. Since I would like to protect the laptop from scratched and dust, health a sleeve is absolutely required. So, medications from my perspective, the only solution to this problem was to do one myself.

I had an old blazer from my girlfriend’s father that was too oddly shaped to fit anybody I know, but I liked the fabric and I thought that it could become a very nice laptop sleeve. The only problem about that idea is that I do not know how to sew. Of course, not knowing how to do something, has never stopped me before and is not likely to stop me any time soon.

Materials

  • Old blazer
  • Zipper
  • Fabric Marker (not required but rather cool)

Doing it

Making this was surprisingly simple since I expected great difficulties coming from the sewing part. I decided to go with a design as simple as possible and to minimize the number of stitches, this resulted in making something extraordinary similar to a simple cousin.

I simply cut a rectangle big enough so that, when folded in half, it could contain my laptop from the blazer and then stitched the bottom and the side of the resulting pouch.  Then, I added a zipper to the top. I used zigzag stitches all the time and, of course, I sewed the sleeve from the inside.

Also, I chose a section of the blazed which had an internal and external pocked so I could use them to carry some extra stuff. Furthermore, I kept the (synthetic?) silk interior lining that looks better than the bare exterior wool.

Finally, I wanted to ad some decorations to the pouch so I decided to use my brother’s fabric markers (he is using for making pretty cool disguises) to ad the word “Linux” to one side of the sleeve. Then I asked him (since he is much more talented than me at drawing (and since I am very lazy) to draw Tux on the back. To achieve that he used a stencil made from the image below that I got from the internet.

I think the final result is pretty cool and very useful. The pockets are great, I can put all of the things that I usually need to carry with my laptop (e.g. mouse, headphones, USB keys) without any troubles. The only thing missing is perhaps a handle that I may add in the future.
