# mini-HANNAH: a little "electronic buddy" for the Cardputer that learns to talk to you in tones — no AI, no LLM, not a single line of TensorFlow

It's not a voice assistant. It doesn't understand words, and it never will — on purpose. mini-HANNAH listens, converts what it hears into a binary signature, and replies with a sequence of sliding tones generated by a network of 64 cube-nodes that learns by reinforcement — Hebbian-style, but built out of pure AND/OR/XOR logic gates. Over time it develops its own voice timbre, learns to recognize when you say yes or no, and its "personality" survives you pulling the battery.

## Why this might interest you

- **Zero black-box AI.** All the "intelligence" is 64 nodes with 8 links each (a 3-bit cube per node), weights that rise and fall with use, and 6 boolean gates the network itself tests and picks between — there's no trained weight matrix anywhere, this is genuinely discrete logic.

- **Hand-built voice synthesis, sample by sample** — no fixed-note `tone()` calls. Each "phoneme" is a frequency curve with its own vibrato and envelope, and the whole voice has a persistent "vocal DNA" that's seeded at boot and drifts very slowly over time.

- **An identity ritual on first boot**: you teach it how you say its name, how you say "yes," and how you say "no" — and from then on it recognizes those patterns without asking again.

- **Everything persists to flash (LittleFS)** — turn it off, turn it on tomorrow, it's still the same one.

- **No speech recognition, no internet.** 100% offline, 100% on the Cardputer itself.

## Set your expectations right

Think of it more like a Tamagotchi with perfect pitch than like an assistant. The goal isn't for it to understand what you say — it's that after a few days of use, you recognize its voice and know roughly what it's "telling" you, even though it's not speaking your language.

This is my fully functional prototype at the moment.

I Ching, with a generator, with a manual throw interpreter—that is, you input the coins for each throw and it tells you the hexagram.

Also combining trigrams or just querying hexagrams.

It includes ordinary decimal and binary values.

In the calendar, you can check the number of days you've been alive, the lunar phases (current, past, or future), the upcoming equinoxes and solstices, the day of the week for any date in the past, present, or future via a perpetual calendar, the remaining days until a given date, and the horoscope according to your birth date (zodiac and Chinese).

On the clock, we can see the time, set alarms, time events, and time rituals. As well as other functions (world clock).

In biorhythms, we can calculate daily, weekly, and monthly values, as well as critical days and couple compatibility. For decades, it was considered science. (Calculations based on studies by Chikinosuke Tatai and Krumm Heller.)

Additionally, in the utilities section, you'll find a binary-to-decimal and vice versa converter, a list of prime numbers, a coin tosser (1, 2, or 3), a Magic 8-ball (based on an octagon, not a ball), a random YES/NO, and a few other bits (TRNG used for randomness).

Furthermore, the Veritas system is an expert system extracted from a legacy expert system and adapted to support decision-making in work, economic, sentimental, and general matters.

A guest function is also included to calculate biorhythms and horoscope, as well as other data based on their birth date.

Issues still:

· Ghosting and refresh.

· Translation details.

It's my personal oracle. On other occasions, I share my I Ching devices here, and this is in a way a device that encompasses many functionalities from my Python, C, C++ programs and different devices and platforms into a mini e-ink... It helps me in my day-to-day life for practically everything.

Oh, and in settings, you can configure the hemisphere (for calculations) and the language—I have it in Spanish and English (in case I use it with someone else and because it's more universal).

I don't think it's ideal for displaying long texts, but it is for queries. Even important ones. It's not a toy... In fact, I have a lot of respect for all my I Ching versions, and that's why I included other forms of divination.

I love the biorhythm topic and I usually print my months on a roll thermal printer; I worked on that functionality, but it barely leaves me any space just because of the Bluetooth libraries.

For me, predicting is an act of calculation in a discrete universe. The Mawangdui texts and the origin of binary, as well as the ideas of Leibniz, Boole, Shannon, Joscha Bach, Wolfram, Chailin, Volstrom, and so many others, support it as plausible at least... So this is my tool.

I just LOVE It.

Discrete universe? Digital I Ching on Cardputer (Broken screen) as Personal oracle.

Binary coin system. 000 - 0 changes 111 - 1 changes

001 - 0 010 - 0 011 - 1 100 - 0 101 - 1 110 - 1

b1, b2, & b3 transition from 0 to 1 at different speeds and cycles. From 000 to 111

So you get the hexagram, real Binary order, decimal valué and more. No coincidence.

Leather case btw!

Electronics was born from logic. There are three fundamental logics... these allow for others. Binary logic from the I Ching and from Fuxi to Leibniz, Shannon, and Boole. Before you ask about randomness, it doesn't exist and we can't replicate it. Regarding my program, it simulates three coins as a 3-axis cube (xyz 0.0.0 to 1.1.1y). When you press a button, it loads the current combination and generates a hexagram. The device is an HP 95lx for many reasons: durability, programming language, and type of technology. It's simple to understand and work with, written in C for Aztec C C86 and compiled on the device itself. The result is the actual binary code, the hexagram, and other information for interpretation. I've had it for years; it's built to last. I used to use a printer with it as well, but now I only use it this way. It uses two AA batteries and one CR2032, both of which last more than a month without any problems. It's undoubtedly the best oracle, and I only use it when absolutely necessary. I fear its answers, and it's always right about absolutely everything. That's why I'm afraid to use it.

I just wanted to share this since I wasn't familiar with the community.

Cheap journal. Zebra printer. Ricoh gx100 camera. Paper tape. Acetate.

The paper works, it's super indestructible, with a protective coating and superb print and feel. It's water-resistant, lightfast, and made to last. It's used in ultrasounds and cardiography; it's medical-grade material of extremely high quality. Nobody uses it anymore, and definitely nobody uses it for photos. I bought both rolls for €5, 38 meters in total... 110mm wide in Paperang C1 Max. The downside is that I have to cut it with scissors; it's impossible to tear it by hand.
