Today’s project was a hard drive carrying case. I wanted something to securely store hard drives. When I looked around on ebay and amazon, I saw some [nice cases](https://www.amazon.com/gp/product/B007OXK0YM/ref=as_li_qf_sp_asin_il_tl?ie=UTF8&tag=za3k-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B007OXK0YM&linkId=350884a6d81cab8bc2fd02af3ba9ce42) and some crappy plastic molded ones. Even the terrible ones were at least $50, so I made my own.

I bought a used ammo case at the rather excellent local army surplus store. Then I padded all sides. I had spare [EVA foam](https://en.wikipedia.org/wiki/Ethylene-vinyl_acetate) “puzzle piece” style mats from a gym setup lying around. I cut out the pieces with scissors. That’s it. I was expecting more steps, but nothing needed glued in place. I was planning on adding inserts for the empty slots, but it seems secure enough. If you’re making one, you could also glue the top onto the lid, so you don’t have to take it out manually.

In a real computer, we obviously can’t just move alligator clips around. Instead, we attach wires to all 9 posts–three outputs wires for the horizontal lines, and six inputs for the vertical lines. We output a signal on the first horizontal line, and see if we can read it from any of the six vertical lines inputs. Then we output a signal on the second horizontal line, and see if we can read it, and so on for the third. Assuming only one key is pressed (or none), we can identify the key. This “scanning” process could be done thousands of times a second, rapidly enough that it can’t miss our slowpoke human fingers.

And this is how most keyboards work. There are some special keys–Shift, Ctrl, Alt, etc might be on their very own line, since we want to detect key combos. And better keyboards can detect multiple keys being pressed at once (N-key rollover), which I think they do by having a completely separate wire to each key which multiple people tell me they do with a diode next to each key.
This was my third attempt. Here’s the second, using aluminium foil. It worked at least as well, maybe better, but it was harder to make. I just taped the foil down, taking care not to cover the contact points. I am told the aluminium will gradually oxidize, making it non-conductive.

And here’s one using graphite from drawing hard with a #2 pencil.. Graphite, it turns out, works terribly, and I couldn’t read a signal halfway down the index card. Despite what people have told me, I’m not yet convinced you can make a conductive wire out of it.

I’m not the first, there have been many other such devices before. I came up with the idea independently, but the specifics are heavily inspired by the [Ultimate Writer](https://alternativebit.fr/posts/ultimate-writer/) by NinjaTrappeur in 2018. Similar to him, my use case is typing without distractions, and reading books. E-ink displays are quite slow to update, so I don’t think it can serve as a general purpose computer. Here’s a video of it in action. It operates at one frame per second.
-The electronics are not fully done. They need better secured, and I’m going to redo the cabling and power back.

-I found a really nice, cheap mechanical keyboard on ebay. The main downside is that it’s heavy–730g. It also consumes heavy amounts of power, even when not in use. I have a nearly identical keyboard that doesn’t, which I’ll use for v2.

-The prototype is powered by a Raspberry Pi 3. The final version will use a microcontroller to save power. The Pi Zero can also be swapped in with no changes, and uses a third of the power. But it’s noticeably slower and takes 30 seconds to boot. For prototyping I’m using the Pi 3 for now.

We found this little $5 tool to be incredibly good for cutting bamboo. It’s designed for almost the same thing, cutting metal pipes.
The visuals are pretty much the same. Incidentally I discovered the striations on the ground disappear if we increase the floating point precision.

Render on the GPU is 30x faster (0.05 fps -> 3 fps). That’s still not very fast.
I didn’t get video working yesterday, or anything else visually new. I will call this one a failure overall, because I have nothing interesting to show off. I learned stuff and made progress though, so it’s not so bad.
Mine is based on the explanation (and code) from “[Ray Tracing in One Weekend](https://raytracing.github.io/books/RayTracingInOneWeekend.html)“, and the code from “[My Very First Raytracer](http://canonical.org/~kragen/sw/aspmisc/my-very-first-raytracer.html)“.

-Matte spheres in different shades of grey. The blue in the spheres is reflected from the sky.

The motivation for this project was to learn how to make things run faster on a graphics card. I quickly realized (before I wrote a line of code) that I’d need the basic raytracer to be its own project. Having it run faster will have to be a job for another day!

First, I tried laminating it. Almost no ink transferred, and the paper came off easily. Then I tried ironing it, but the paper stick to the iron and not to the PCB. The tape melted on the iron. For both, I dunked them in water after, which is supposed to help loosen the paper.

+
Next, I tried the standard advice–sand the PCBs (I used 320 grit) and use glossy paper. This time, both pieces of paper stuck very well. I was wary about the iron coming off again, so I just left it on place on the highest heat–this worked fine for adhesion, but I had to iron out wrinkles at the end. The laminated piece had lose edges, while the ironed piece was on there totally flat.
I tried peeling off the laminated paper–oops! It peeled back and most of the ink stayed on the paper. I think if I took it off more carefully, it would have worked.

So to make a nice geodesic dome, we could find one (I failed), make one in Blender (too hard), or use some math to generate one in Godot. And to do that math, we need to know the list of 20 icosahedron faces. Which basically just needs the list of the 12 vertices!

The final product is that for each file like `ticket.jpg`, we end up with `ticket.txt`. This has metadata about the file (tags, category, notes) and a transcription of any text in the image, to make it searchable with `grep` & co.

First, I clean up the images. Crop them, rotate them if they’re not facing the right way. I can rotate images with keyboard shortcuts, although there are also buttons at the bottom. Once I’m done, I press a button, and *scan-organizer* advanced to the next un-cleaned photo.

Next, I sort things into folders, or “categories”. As I browse folders, I can preview what’s already in that folder.

Renaming images comes next. For convenience, I can browse existing images in the folder, to help name everything in a standard way.

I tag my images with the type of text. They might be handwritten. Or they might be printed computer documents. You can imagine extending the process with other types of tagging for your use case.

I write up all my handwritten documents. I have not found any useful handwriting recognition software. I just do it all by hand.

Recipe is mostly from [Tricia](http://triciaroxanne.wordpress.com).
Ingredients:
I thought, if these books are just a local convenience for an online version, it’s more artistically satisfying to have some representation of that. So I printed up a card catalog of all my books, both the ones I have digital copies of and not:
-[](https://blog.za3k.com/wp-content/uploads/2014/11/sample_card.png)
+[](https://blog.za3k.com/wp-content/uploads/2014/11/sample_card.png)
An example catalog card
That’s what a card looks like. There’s information about the book up top, and a link in the form of a [QR code](http://en.wikipedia.org/wiki/QR_code "QR code") in the middle. The link downloads a PDF version of that book. Obviously being a programmer, the cards all all automatically generated.

Book with a card inside
For the books where I have a physical copy, I put the card in the book, and it feels like I’m touching the digital copy. My friends can pirate their own personal version of the book (saving me the sadness of lost lent-out books I’m sure we’ve all felt at times). And I just thing it looks darn neat. Some physical books I don’t have a digital version of, since the world is not yet perfect. But at least I can identify them at a glance (and consider sending them off to a service like [http://1dollarscan.com/](http://1dollarscan.com/))

I wanted a partition to divide my room, and I had a whiteboard sitting around. I sawed it into three parts, and connected them with hinges:
-
+
folding whiteboard
-
+
hinge (front)
-
+
hinge (back)
I’m a little embarrassed at having done all this, since it was obvious as soon as I started the partition was way too short to work. I figured I’d still get some experience woodworking (this is my first project). Here’s where it went:

and I never saw it again

In space no one car hear “whoosh” sounds but action potato is so cool you still can mostly.
Next up I have to clean the site up, because it looks like this:

Compared with [last update](https://blog.za3k.com/wip-dead-tree-publishing-2/ "WIP: Dead Tree Publishing 2"), the Dead Tree Publishing website is looking nicer.

I consider Dead Tree Publishing to be **G**ood **E**nough at this point. It’s launched.

New site style, FAQ page
First you upload a PDF:

Uploading a book
Then I tell you what your ordering options are (hardcover, softcover, color), and what they cost. I’m also supposed to ask you your address to ship the book, and for you to pay for it, but those aren’t done yet.

Or how to attach headers to the inside of an existing keyboard, which looks like this–:

But I found a project called [GOLEM](https://golem.hu/guide/keyboard-build-logs/) with an excellent guide to making your own keyboard. Here is their wiring:
