Progress Update 11/10/2024

Haven't made a progress update in a bit, but want to keep documenting changes and interations even if they are small. So here we go.

The majority of the focus recently has been on developing the Viewfinder for the Interpreter. One of the major pieces of design I want to incorporate into this is a 3D viewing space, akin to a hologram/projection/Pepper's Ghost. My original plan for this was to modify this design. I saw this concept about a decade ago on Instructables I think and thought it was really cool.

My modifications were going to be using four separate OLED displays each running either the original or a mirrored or rotated version of the original gif/movie/image, rather than a single screen with the four images on it together. There were some pros and cons of this I had convinced myself of, but one of my barriers on progress in this method was related to having the Arduino I am working with not having enough breakout pins for the type of data pins I need for four screens. My soldering skills aren't amazing, so getting four of them hooked into one set of pins was daunting.

However, I found this video a few days ago, and was reintroduced to Retroreflectors. Video goes over the basics of the tech, and even takes it a step further by introducing ways to make it into a "touch screen". However, that's extra complexity and not what I want for this Viewfinder anyway, so it's possible I can just snag the reflector part of their build and significantly reduce the complexity in my own design.

This now leaves potential for a much larger image size, as before I was limited to 128 x 64 pixels, as I wanted to keep the footprint small, which majorly limited screen size to fit with needing to cram four into the space. So bigger canvas size is great! Fewer electrical components is also great! Now is just getting in some sample materials for testing the holographic display part itself.

Another part of the project I've been working on is the music. Less progress here, but I have started to tinker with a program to add in drums which I think will add a much-needed layer to the music I have been working on.

That's all for this one, I am hoping to have materials in a couple weeks, and I am clearing out some sidejobs that also will help fund this endeavor.

An amazing documentary on an older bit of computer technology that uses punchcards. What makes this more amazing too, is that this is a VERY old form of programming that dates back to the 1700s. Before we had these types of electric punchcard computers, Paper punchcards were used to make weaving patterns for things like dobbies when making jacquard fabric and lace patterns for big looms, automatons, and in a lot of ways works like the drum on a music box. It's a way to have mechanical programming instead of coding electronics. Electronics are smaller, load faster, and can hold much much more data, but Punch card equipment has it's own benefits as well. I'm actually old enough and fortunate enough to have handled old punch card and mag striped equipment when helping my mom in her classroom, it was a very outdated tech then. But it's not just charming, fun to use, and fairly simple to pickup, it's practical, and at least for me I can understand it better than I can with coding now due to my issues with losing my memory. Honestly it's a fascinating rabbithole to go down, because it leads you to analog technology and how simple it really is. From the fact that a speaker is just something that can vibrate a pattern like a piece of cardboard or rubber attached to a needle being cranked over a record like this:

You'd be surprised what you can do mechanically. And a solid mechanical build combined with simple electronics like an arduino if you're able to learn can make amazing things.

AH I REMEMBERED WHAT I WAS GONNA SAY EARLIER but it's kind of stupid, lmao.

So my partner is getting into brewing beer and I got them a Tilt, which is a Bluetooth hydrometer. It measures specific gravity and temperature, which are things you want to know so that you don't kill your yeast or whatever. Except the sensor's Bluetooth range is super short, and it basically runs via a phone app, and the temperature we're logging currently is the crawlspace, accessible via the staircase closet. So they were like, wait, what do we do about this, because I can't leave my phone in the closet, that's my alarm clock.

In a kind of ridiculous turn of life imitating art, I was like, hold up, I got just the thing right at my desk. Bam. Old phone. We just needed to scrounge up a charger because the battery is so dead that after charging just enough to power on it claimed it was at 53% (to be fair to it, there is a very real chance that it's correct, and it just holds no charge at this point so the capacity is just THAT low) and now it lives in the closet logging sensor data.

And I was like, you know...didn't I just solve a major story detail with a much larger version of this...yeah, no, this is all vaguely familiar somehow, power supply issues and all. Kind of cool that the concept works though. Kind of weird that it came up at all?

We are not gonna talk about the fact that I still have at least two more ancient-ass phones in a drawer where that came from because look, man, sometimes you just need a camera/mic/mini computer with Bluetooth and wifi that fits in a pocket, and people just get rid of these things, but not me. I actually could build a shitty security system out of them if I was reaaaally inclined. I mean. I'm not. But it's technically possible.

For real though, If I pick up any stupid maker projects I still high-key am thinking about slapping Bluetooth into a necomimi headset and running that through an Arduino and learning to code just enough to let me skip songs/change the volume on Spotify with my brain, because it's entirely doable, and I mean yeah I could do that on my phone remotely too, but that's not funny, now, is it. I'm just not sure it's $350+ of parts funny. Kind of a big investment just to prove the point that haha look I am the extremely ADHD type of lazy where I would rather solve a problem via the most convoluted and complicated Rube-Goldberg type ass machine way possible rather than just perform a single simple action.

YEAH I'VE BEEN THIS SCATTERED ALL DAY AND I REALLY SHOULD GO TO BED SHOULDN'T I. I started playing Satisfactory. Mistakes were made. I'm going to dream about conveyor belts again and I did it to myself...

Acoustic & RF Sensors: Microphones, sonar, and RF sensors for detecting vibrational, audio, or electromagnetic signals.

2. Software Stack and Data Flow Pipeline

Data Ingestion:

Frameworks: Utilize Apache Kafka or Apache NiFi to build a robust, scalable data pipeline that can handle streaming sensor data in real time.

Protocol: MQTT or LoRaWAN can serve as the communication backbone in environments where connectivity is intermittent or bandwidth-constrained.

Data Preprocessing & Filtering:

Edge Analytics: Develop tailored algorithms that run on your edge devices—leveraging NVIDIA’s TensorRT for accelerated inference—to filter raw inputs and perform preliminary sensor fusion.

Fusion Algorithms: Employ Kalman or Particle Filters to synthesize multiple sensor streams into actionable readings.

Data Abstraction Layer:

API Endpoints: Create modular interfaces that transform fused sensor data into abstracted, standardized feeds for higher-level consumption by the AI core later.

Middleware: Consider microservices that handle data routing, error correction, and redundancy mechanisms to ensure data integrity under harsh conditions.

3. Infrastructure Deployment Map

4. Future Hooks for Empathic AI Core Integration

Data Pipeline Setup:

Set up your data ingestion framework (e.g., Apache Kafka cluster).

Prototype and evaluate basic preprocessing and fusion algorithms on your chosen edge device.

Field Testing:

Deploy the prototype in a controlled environment similar to your target extremes (e.g., a pressure chamber, simulated low-gravity environment).

Refine data accuracy and real-time performance based on initial feedback.

Integration Preparation:

Build standardized API interfaces for future connection with the Empathic AI Core.

Document system architecture to ensure a smooth handoff between the hardware-first and AI-core teams.

Elmalo, this blueprint establishes a tangible, modular system that grounds Iron Spine in reality. It not only demonstrates your vision but also builds the foundational “nervous system” that your emergent, empathic AI will later use to perceive and interact with its environment.

Does this detailed roadmap align with your vision? Would you like to dive further into any individual section—perhaps starting with hardware specifications, software configuration, or the integration strategy for the future AI core?

one of the biggest shocks to me about the ham radio world has been how out of step it is with the consumer electronics world (at the cheap end, at least).

like, you'd think that with the flood of cheap handheld software-based transceivers now from brands like Baofeng, that they'd throw a standard consumer audio-type headphone jack on the thing and let you get audio out to any set of headphones or headsets. but uhhhh. no. you can't do that. this is equipment that came out of spaces adjacent to/ovelapping with professional audio/RF engineering. so the mics on big kid radios are using like. XLR hookups. Maybe some of them have some more basic consumer outputs, but that seems to be reserved for the projects that also come from hobbyist computing directions, stuff like Arduino/raspi-based projects.

there ARE audiocable-type interfaces for the handheld type radios, but they are not compatible with headphones unless you do some soldering or chain together adapters. one of the de facto standards these days seems to be the "Kenwood" type connector, which is a set of adjacent 2.5mm and a 3.5mm TRS jacks. If I want to program my Yaesu handheld I need a special cable with an integrated circuit that converts USB to this two-prong serial interface thing.

the beater radio i just picked up does bluetooth programming AND USB-C programming, but it still has no simple audio out! (the BT is program-only, no audio) It was easier and more attractive for them to put a bluetooth module in there hooked up to serial port than it was to add a headphone jack. and it's like. the only one I know of on the market with a USB-C port for charging and programming.

it's a weird bit of culture shock for me coming from the gaming/PC enthusiast side, where my feature-language is "mic jack for audio, some USB format for data and power, bluetooth audio if you're fancy". I consider PCs and gaming to be my "primary" hobby, and everything else is an extension of that. My interest in radio is partially driven by having all this compute power literally next to my feet, knowing there's all this information going through the air around me, and getting frustrated that I can't interact with it. I want to add new capability to my battlestation! and i'm running into barriers on things that in my usual world were solved problems long ago
