Interesting computer input devices.

I haven’t used every single one and probably never will, but weird, new, or particularly clever ways of interacting with a computer always spark my interest. It’s probably because growing up on the NES, I would get game magazines that had articles describing all the cool stuff they had in Japan and had advertisements for new Nintendo controllers that nearly always looked way better than they worked.

<Digression> In my opinion there were only two good controllers available for the system: the one that came with it and the NES Max. The one it shipped with could take a beating and still work.  The NES max was shaped perfectly and made control much more precise.  And my Dad, who has the use of only one hand, was able to use it to play video games with me.  It’s the only controller that worked for him. Always wanted to get him one of these.< /Digression>

Today, I’m getting a mouse that’s shaped like a pen.  I have no idea if it’s going to be any good but lately I’ve just wanted a mouse with a pen form factor.  Here’s why.  I don’t like working on a graphics tablet for the majority of my designs.  I like using a mouse (I have an Evoluent wired vertical mouse the I’ve been using for years and has been a lovely piece of kit). For some things I use an Intuos (an older model).  But for Illustrator and Rhino, I wanted something that was in-between the two and thought a mouse you held like a pen would be the way to go.

So I did a google search for “mouse pen” and “pen mouse” and there isn’t much to choose from.  There’s the low end of the spectrum - which is what I purchased - and then there’s the high end of the spectrum - which isn’t that high but still high enough where if you got a dud product and couldn’t return it, you’d be sort of pissed.  The reviews were actually better for the cheap one too.  I think the reviews on both though might be marred because the right people might not be using the products, e.g. - people trying to use it just like a mouse or just like a graphics tablet stylus, i.e - the wrong customers; so I don’t put much faith in the good or bad reviews.  QED.

After a couple of weeks playing around with the thing, I’ll let you know how it goes.  It might be that I’ll just end up having to design one of these things myself.

Reynisfjöruperla Hengiskraut

Reynisfjarasperlur Hengiskraut

I wasn't sure what would come out of my little experiment with titanium and Icelandic beach pearl - but despite some setbacks the Reynisfjöruperla Hengiskraut is complete!

The pendant is made from 3D printed titanium and was manufactured for me by the good folks at i.materialise. Originally I wanted the Reynisfjöruperla  - a beach pearl from Reynisfjara Beach - to float in a titanium embrace.   You'll remember from my previous entry on this project that the pendant snapped when I attempted to mount the pearl.

After it snapped I contacted Dmitriy at i.materialise to see if 3d printed titanium was by nature brittle and if there was any way to design around that property - such as taking account of any anisotropic properties of the metal. He noted that the pendant might be slightly less strong in the direction perpendicular to the Z axis (though he doubted that was the case with my model). After checking, the titanium team concluded that it's possible to break a 4-5 mm thick titanium part with basic tools and manual force! The grooves on the model made it around 3 mm thick in certain areas which could have amplified the force I applied thus making the part break more easily than otherwise.

Live and learn. 
I put a LOT of work polishing the titanium and wasn't just going to give up.  I sat on the pieces for a bit until I came up with drilling a hole to match the diameter of the broken parts and assembling everything to look like the metal had pierced the Reynisfjöruperla.

After boring through the Reynisfjöruperla with my trusty Dremel I used a combination of shaped bits to widen the opening just enough for the two halves to connect.

Once I fit the metal pieces back together and decided on the placement of the Reynisfjöruperla, I mixed some two part epoxy with some of the drilling powder. After assembly it was time to wait.

Here is what it looked like after a couple of hours - well after a little bit of polishing, too.

I'm pleased with my Reynisfjöruperla Hengiskraut, especially next to the ring I picked up from Gullkúnst Helgu in Reykjavík.
EDIT:  Shoutout to Benni R for letting me know the correct way to turn Reynisfjara Beach pearl into a real Icelandic word.

Working with Titanium

I finally designed something to specifically make in titanium. This how it has shined up after maybe a minute with my bench polisher.

It's going to be a pendant. It has a piece of Iceland mounted inside. It's from one of the many beautiful black sand beaches they have.

I plan to polish the titanium to a mirror shine with some areas left worn.

EDIT:  2018/10/01 - See Below.

I'll see if I can salvage something from this design!
