Hack On Self: The Alt-Tab Annihilator

Last time, I told you about a simple script I made to collect data about my laptop activity, talked about why collecting data about yourself is a moral imperative, and shared the upgraded script with you alongside my plans for it. Today, I will show you a problem I’ve been tackling, with help of this script and the data it gives, and I also would love to hear your advice on a particular high-level problem I’m facing.

Today’s problem is as old as time – I often can’t focus on tasks I badly need done, even ones I want done for myself. This has been a consistent problem in my life, closing off opportunities, getting me to inadvertently betray my friends and family, hurting my health and well-being, reinforcing a certain sort of learned helplessness, and likely reinforcing itself as it goes, too.

It’s deeply disturbing to sit down fully intending to work on a project, then notice no progress on it hours later, and come to a gut-wrenching realization you’ve had hundreds of such days before – I think this screws with you, on a fundamental level. Over the years, I’ve been squeezing out lessons from this failure mode, making observations, trying out all sorts of advice, in search of a solution.

Join me today in non-invasive brain augmentation and reprogramming, as I continue trying to turn my life around – this time, with help of my laptop, a computer that I already spend a ton of time interfacing with. Ever notice that starting work on a taskĀ  is often the hardest part of it? It’s the same for me, and I decided to hack away at it.

Hack On Self: Collecting Data

A month ago, I’ve talked about using computers to hack on our day-to-day existence, specifically, augmenting my sense of time (or rather, lack thereof). Collecting data has been super helpful – and it’s best to automate it as much as possible. Furthermore, an augment can’t be annoying beyond the level you expect, and making it context-sensitive is important – the augment needs to understand whether it’s the right time to activate.

I want to talk about context sensitivity – it’s one of the aspects that brings us closest to the sci-fi future; currently, in some good ways and many bad ways. Your device needs to know what’s happening around it, which means that you need to give it data beyond what the augment itself is able to collect. Let me show you how you can extract fun insights from collecting data, with an example of a data source you can easily tap while on your computer, talk about implications of data collections, and why you should do it despite everything.

Hack On Self: Sense Of Time

Every now and then, a commercial product aims to help you in your life journey, in a novel way, making your life better through its presence. Over the years, I’ve been disappointed by such products far more often than I have been reassured, seeing each one of them rendered unimaginative and purposeless sometimes even despite the creator’s best intentions. The pressures of a commercial market will choke you out without remorse, metal fingers firmly placed on your neck, tightening with every move that doesn’t promise profit, and letting money cloud your project’s vision. I believe that real answers can only come from within hacker communities, and as we explore, you might come to see it the same way.

This is the tip of the iceberg of a decade-long project that I hope to demonstrate in a year or two. I’d like to start talking about that project now, since it’s pretty extensive; the overall goal is about using computers to help with human condition, on a personal level. There’s a lot of talk about computers integrating into our lives – even more if you dare consult old sci-fi, much of my inspiration.

Tackling a gigantic problem often means cutting it down into smaller chunks, though, so here’s a small sub-problem I’ve been working on, for years now, on and off: Can you use computers to modify your sense of time?

Keebin’ With Kristina: The One With The Duplex Typewriter

The Coleco Adam? A not-so-great home computer that likely contributed to the downfall of the company. The keyboard, however, is a different story, and worth repurposing.

[Nick Bild] has created a USB adapter that uses a Teensy 4.1 and an RJ-12 breakout board. Now this wasn’t just a simple matrix to decode. No, the fine folks at Coleco rolled their own communications protocol called AdamNet.

The keyboard uses an RJ-12 connector and a single data line to communicate over a 62.5 kbit/s, half-duplex serial bus. Inside the keyboard is a Motorola 6801 that caches the key presses and sends them to the computer. So the BOM is limited to what you see above — an RJ-12 breakout and a Teensy 4.1. It’s great to see old keyboards come alive again, especially one with such cool sci-fi keycaps. Want to hear it clack? Of course you do.

Our Curious Relationship With Caffeine

If you were to paint a few stereotypes surrounding our community, where would you start? Maybe in apparel habits: the t-shirt from a tech conference, or the ubiquitous hoodie. Or how about leisure pursuits: gaming, or even D&D? There’s one thing I can think of that unites most of us, we have a curious affinity for caffeine. Is it a propensity for working into the dark of the night that’s responsible, or perhaps those of us with ADHD find the alertness helpful, but whatever it is we like our coffee and energy drinks. Rare is the hackerspace without a coffee machine and a fridge full of energy drinks, and I have lost count of the times I have been derided by the coffee cognoscenti among my peers for my being satisfied with a mug of mere instant. Deprived of my usual socialisation over the festive period by the pandemic, and contemplating my last bottle of Club-Mate as I drank it, I took a while to ponder on our relationship with this chemical.

Bringing Back The Fidget Toy Craze With The Magic Microcontroller Cube

[Rickysisodia] had a few dead ATmega128 chips laying around that he didn’t want to just throw away, so he decided to turn them into his own light-up fidget toy. The toy is in the form of a six-sided die so small that you can hang it on a keychain. He soldered an ATmega128 on each side of the cube and added a few dot circles to give his toy the look of a functional dice. We were pretty amazed by his impressive level of dexterity. Soldering those 0.8 mm-pitch leads together seems pretty tedious if you ask us.

Then he wired a simple, battery-powered tilt switch LED circuit on perfboard that he was able to sneakily place inside the cube. He used a mercury switch, which, as you may figure, uses a small amount of mercury to short two metal contacts inside the switch, completing the circuit and lighting the LED. We would suggest going with the non-mercury variety of tilt switches just to avoid any possible contamination. You know us, anything to mitigate unnecessary disasters is kind of a good route. But anyway, the die lights up a different color LED based on the orientation of the cube and it even blinks.

This is a pretty cool hack for wowing your friends at your next PCB art meet-up. We’ll probably put this in the electronics art category, so it doesn’t get lumped in with those other ever-beloved fidget toys.
