- The small square (1) inside the key is actually made of two metal pieces sandwiched together.
- When a key is pressed, key holder (3) moves down and pushes the center of the metal piece that looks like a Y (2) against the center of the square (1). That’s what closes the circuit and registers the key press.
- There’s also a spring (not shown in the picture) that brings the key holder up again after the press.
I have been brewing this idea for over 10 years!
Everything clicked when I looked at a scrap piece of acrylic board from one of my maker projects.
I want to start by saying that this is not for task management. The goal is to have a clearer view of all of my current and upcoming activities by giving me a bird’s-eye view. Apps like Evernote, Obsidian, and others can handle all the details much better. However, there are still some adjustments I would like to make to the system before I share the specifics of how it works.
For now, let’s talk about the form factor.
I used different colored rubber bands just to make the picture more interesting. The real ones are black, as you can see in the picture of the prototype below. In other words, the colors have no special meaning at all. As for the material and size, there is a reason for that.
Given that it will be on my desk most of the time, I would like to always be able to see what is underneath it. That’s why it is transparent. It is the same size as an A4 sheet of paper, which gives me plenty of room to run my system and safely transport it without losing sticky notes. It’s as easy as slipping it into any folio available on the market. Or, like I’m currently doing, just repurpose the paper ones companies give us with proposals or contracts inside.
I wanted something that could be hackable by anyone, and that’s why I used standard measurements. Nevertheless, I am confident that the equivalent of a letter paper size would be a more suitable option for users in the United States.
As things progressed, being hackable became a must-have aspect. For example, at first, the dividers were created with masking tape, but later, rubber bands were used to make the board easier to adapt to new situations or different uses. In the end, they also proved to be useful in preventing sticky notes from falling off.
Vertical lines create stages that work almost like a Kanban board. Almost! Regarding the horizontal divider, it creates what one of my clients nicknamed Driving Lane (top) and Parking Lane (bottom).
I’ll tell you more about the system soon, but don’t expect anything advanced or complicated. On the contrary, it is something simple that covers all of my needs.
I think the hardware is what freed my mind because until now, I couldn’t make my system work 100% with available software. Ironically, following the construction and testing of the board, it opened my eyes to the possibility of implementing my system on some apps. But now, I’m not certain if I want to go that route. Anyway, I’ll also share more about that soon.
I made myself a tool to make it easier to film the Supernote. It is essentially a miniature table with an acrylic top to let the light through. I also cut it to fit the Pixel camera bump. And yes, the next video will be about sending #Supernote files to #Evernote 😉
We now live in a world where knives can't have blades.
I consider myself to be an optimist, but sometimes humanity makes me question the bright future I see ahead of us.
When I saw the logo on that drawer-style box, there was no doubt. I felt my heart beat faster as I pulled one side of the drawer, slowly revealing what was inside. As if it were the most precious jewelry, a Swiss Army Knife lied protected in a carefully carved space adorned with white velvet.
I was probably too young to carry a knife with me when my father gave me such an exquisite gift, but he knew what he was doing. For as far as I can remember, guns and killing were always serious topics in our home. To give you an idea, I once used the expression ‘I will kill you,’ like many other children were doing, and had to listen to a long, very long speech. So, no killing, no guns (including toy guns), and respect for others, were lessons I learned from a very young age.
That wonderful tool went with me everywhere. And I mean everywhere. It was always in my left pocket as a lucky charm. It went to my classes, concerts, planes, everywhere. Of course, that was a different world, and I never, ever thought of it as a weapon. It was always a MacGyver tool that I loved to used to fix and build things all the time.
When I got older and started appreciating wine and wearing glasses, I gave my beloved pocket knife to my son, as I purchased a new one with a corkscrew that doubles as a place to store a small screwdriver.
At some point, perhaps after September 11, we were unable to bring tools like that on board anymore, so the old and then the new one started traveling in my check-in suitcase. I opened many wine bottles, and even fixed the wheels of a large suitcase we dragged in India for too long. But lately, I’ve been doing less of these things on my trips.
It now only travels with me on train journeys, as most of our plane trips in Europe are onboard low-cost carriers, bringing only cabin baggage. When we are not staying in an Airbnb, I always buy a cheap corkscrew that I leave behind in the hotel room. Not ecological at all.
It took me a while back then, but I eventually got used to the empty left pocket. Years latter, my wallet took that spot as the mobile phone moved into the right pocket. I don’t know if you heard the news, but:
The maker of the Swiss Army Knife says it plans to begin offering pocket tools that don’t contain blades. (…) rising violence in certain parts of the world has prompted multiple governments to crack down on what types of blades people can brandish in public, possibly making it harder for consumers to carry the company’s iconic red multitools. (source)
I am not trying to make any point here, and I do prefer to be in a safer environment, but it is always difficult for me to understand why tools are the ones usually punished for human behavior.
Anyway, nowadays, I often have empty pockets because I carry a bag with me most of the time. Inside I have my glasses, my current pocket knife, phone charger, eye drops, the Supernote, and a bunch of other stuff that I probably won’t need, but might be too worried about eventually not having with me.
Maybe that’s what a maker’s fate is. But, that’s a story for another time.
This is the story of how I fixed a Disk II drive
It may sound crazy, but there was a time when Apple computers and accessories could be repaired by the user. This is a story about how I fixed a Disk II drive without any electronics training.
Software and resources used
I cleaned the green phosphor monitor and repaired the crack
Cleaning and repairing a frame crack took a lot of time, but I’m happy with the result. I also closely inspected the capacitors and couldn’t find anything unusual. The board looks like it just came out of the factory, but there is a strange smell coming from the monitor when it is on. I suppose I will have to wait until the mysterious capacitor begins to leak.
Cleaning the Apple IIe
This Apple IIe arrived pretty dead, and even though I don’t have any training in electronics, soldering, or any of the many other skills, I decided I would fix it. The list of problems is endless, and I’ll do what I always do in situations like this. Break it up into smaller problems and solve them one at a time.
First step: cleaning.
How to use both sides of a floppy on a Apple Drive II
The Apple Disk II drive is capable of reading only one side of a floppy disc. To use the other side of a Double Side (DS) disk, you need to flip it like a vinyl record. However, only flipping won’t do the trick.
All 5.25 floppy disks have a cutout on the right-hand side which tells the drive they can be written on. However, if you flip it, there will be no notch, and the drive will not be able to write on that side.
In the past, we had a tool called the Floppy Disk Notcher. But for inexplicable reasons, it became too expensive, and in the end, all you need to do is cut the disk in the right spot.
I use an X-ACTO knife, but if you’re careful, you can use a good pair of scissors as well. To tell where to cut, I use masking tape (see image below) and trace the line by flipping another disk on top of the one I’m cutting.
Understanding the Apple IIe keyboard mechanism
It took me a while to understand the key mechanism because it was different from the one shown in the first video I watched about this topic. Anyway, after several tests and with the help of my son Fernando (yes, he’s helping 👏), we figured it out.
NOTE TO SELF: If I had watched this other video, I would have understood it in minutes. But what’s the fun in that? 😄
How it works
Fixing
In most cases, the solution is simply to bend the Y-shaped metal (2) piece back to its original shape. I think it gets flatter and flatter over time, and the key holder ends up not being able to press it with enough force agains the piece (1).
😮 Oops, I didn’t take my watch off
Remember my video about why I chose a Garmin instead of an Apple Watch? I was sending and painting for a while when I realized I had forgotten to take off the watch. If you look closely enough, you will notice that there are paint drops on my arm. Some of them ended up on the watch, but that’s alright. All you had to do was wash it, and everything worked out fine.
MacGyvering a broken suitcase.
The plan was to contrast two realities that couldn’t be more far apart, by spending a couple of days in Berlin after our long journey across India by train.
It’s January, and since the weather was the opposite in both countries, we had to bring two very different types of clothes. That’s why we are traveling with a suitcase that isn’t the appropriate size for trains.
Long story short, always dragging it sideways on train hallways and then pulling it on the rough terrain around the stations damaged the wheels and turned it into a limping suitcase. Although it was far worse than driving with a flat tier, it didn’t make sense to fix it because it would break again. But now that we are in Berlin, I decided to take a look at the situation.
I thought the wheels were just jammed, but that wasn’t the case. Two of them lost almost all of their bearing spheres, and there’s no way I can fix that with the tools I brought with me.
After some investigation, I was able to dismantle the axle and reposition one good wheel on each side. I was happy to have a working rolling suitcase again, but the wheels were too loose and that was not going to last long. The solution was to MacGyver it by cutting pieces of a pen barrel, which I used as a spacer. And that worked like a charm.
