october 1st 2024: drafts!

preacher: i'm attaching slightly improved versions of our original drafts, but i'll also include mine and scott's garbage sketches under the cut because i think they're a little bit funny

(image id available through tumblr's accessibility options)

this is a slightly revised version of my original concept for "APRIL".

the main functionality i wanted for "APRIL" was for her to be able to read out words from the templeOS god word app, and ideally without needing keyboard input – hence the microphone. ideally all of her parts are going to fit inside a hollowed out mannequin or doll, which will probably just be the torso, so that she's more portable. for the same reason, i want her to run off a power bank – i want to be able to take her places!

if we manage, we're going to give her an animated LED face which moves to indicate when she's speaking. the way i first pitched it, i wanted it to also change a bit depending on how she "felt" – for example, frowning if the environment was hotter than ideal for the raspberry pi to operate on. but that's a bit beyond our current scope right now. i don't think we even ordered a thermostat.

scott drew the following wiring diagrams based off my original sketch. here revised digitally for readability's sake.

(image id available through the tumblr accessibility options although i fear it's not very good in this case. feedback appreciated).

scott: I decided to go with the raspberry pi zero 2w because it's what I've got experience coding on, it's relatively cheap for the "brains" of the operation (heh) and can perform both tasks from the godword prophecy generation, speaker operation and led matrix operation simultaneously. Plus its small enough to keep the circuit lightweight and fit inside the initial mannequin design.

This drawing fits no kind of engineering standard by the way lol. It was an initial sketch closer to a wiring diagram to see how it'd physically setup and wrap my head around transforming it from mains power to being theoretically portable and running on powerbanks. Unfortunately the LED matrix is really fucking power hungry so needs its own power supply of really specific voltage and current draws hence all the converters.

Also because Im using the smaller and cheaper pi, as oppossed to a stronger system like the pi4, it doesn't have any audio out jack so I plan to use the micro usb for audio out which means yet again I need another adapter for a soundcard and usb to micro usb adapters and all that jazz. Usually sound out can be done through the GPIO pins but the LED matrix takes so many pins that I cant really take anything form them so I had to look for other ways of doing it. Plus this way I get to add a soundcard so if we wanna add microphone support or anything later on we can :)

(Also this is all a little obtuse because I'm trying to do it as much as plug and play and screw terminal style as possible rather than actually solder connections for ease of access and initial setup, but this also works for modular design and component swapping later too so its cool.)

preacher: another reason we're going with plug&play is becauuseeeeee i don't own a soldering iron 😭 it's ok. it's ok.

our silly initial drafts under the cut for your viewing pleasure.

preacher: these were made around 2 weeks ago, so about september 15th ish.

as you can see the first "APRIL" drawing was beautifully drawn with my fat fingers in the facebook messenger photo editor. i think it holds up. lol.

I have this Raspberry Pi 4 that I got in 2020 that was basically used for school. But three years later my school website stopped working on there and I have no clue what I should do with it.

I'm not good with hardware but I'm kinda ok with software. Do you guys have any suggestions on what to use?

sometimes you're fucking around with an rpi that you have for 'speriments and you find out bad enough that you need to OS the box and start over.

Should I actually make meaningful posts? Like maybe a few series of computer science related topics?

I would have to contemplate format, but I would take suggestions for topics, try and compile learning resources, subtopics to learn and practice problems

Making your own Home Assistant (theorising)

Disclaimer: This is all theory and speculation. I have not tested anything or made my own home assistant yet, I just looked around for libraries and hardware that are likely compatible. I have not fully tested the compatibility or quality of these, this is simply the first iteration of an idea I have.

I just got news that Amazon Alexa has lost 10 billion dollars because their business model failed. This makes me happy, and has also made me realise that you can make your own home assistant.

Here are some of the links to things (I am aware that some are amazon, but it's the most global I could find. I encourage you to find other sellers, this is just what you should need. If you find anything cheaper or more local to where you are, go for it):

Hardware:

Raspberry Pi 4: https://www.canakit.com/raspberry-pi-4-2gb.html (RAM requirements may differ, I may do testing to see what comfortably runs)

8GB MicroSD: https://www.amazon.ca/Verbatim-Premium-microSDHC-Adapter-10-44081/dp/B00CBAUI40/ref=sr_1_3?crid=3CTN6X9TJXRR2&keywords=microsd%2Bcard%2B8gb&qid=1699209597&s=electronics&sprefix=microsd%2Bcard%2B8gb%2Celectronics%2C91&sr=1-3&th=1

Microphone: https://www.amazon.ca/SunFounder-Microphone-Raspberry-Recognition-Software/dp/B01KLRBHGM?th=1

Software:

Coqui STT: https://github.com/coqui-ai/STT

Coqui TTS: https://github.com/coqui-ai/TTS

If you have it set up correctly, you should be able to run both the STT and TTS in realtime (see https://github.com/coqui-ai/TTS/discussions/904).

After all of them are set up, the only thing to do is bridge it all together with software. There are bindings to Rust for both Coqui libraries (https://github.com/tazz4843/coqui-stt and https://github.com/rowan-sl/coqui-rs), and all that's left to do is implement parsing.

The libraries can also be swapped out for different ones if you like. If you can find and implement a DECtalk library that works for the Raspberry Pi, you can use that.

If I ever figure out how to manifest this idea, I will likely make the project modular so that you can use whatever library you want. You can even fork the project and include your own library of choice (if you can bind it to Rust).

Go FOSS!

october 8th 2024: so many updates!!

preacher: guyssssssssssss!!! APRIL is homeeeeee!!!!!

we will post the contents soon. i already had time to open it and look over everything. the pi zero is so tiny and the raspberry logo decal is so cute 😭 i can't wait to post pictures.

unfortunately, the LED matrix is far bigger than we planned :/ there is no way it could fit in the face the way that i imagined. i think either we will end up installing it in the chest, or mounting it on the head in such a way that the top part is obscured but the chin and mouth are still visible? kinda like, angel halo style, idk... in any case we will figure something out.

also, scott painted the mannequin while i was at school!

we're skipping the legs since we'll be chopping those off anyway. in any case, it already looks much better but we'll still be putting another coat of paint on top so that it's glossy. (we got radiator paint. it's the only kind they had. what can you do.)

also, also: the usb converter arrived yesterday, so we can post some more code later :P now that we can finally view it. lol

i'm so excited. we're soooo close to putting the whole thing together now!

I will add that for Linux, there are some programs that can be used to run Windows programs - I believe you can use Proton for video games and Wine for non-video games applications. I've also heard that Mint is generally recommended more highly than Ubuntu these days but I don't know how new-user-friendly it is as my current exposure to Linux is through the Steam version.

Disclaimer: I am very new to Linux and only know the above due to cursory research as I'm looking into divorcing Microsoft for my next PC build (and I want to be able to get custody of Scrivener in the process, which doesn't have a recent Linux version). I'm getting sick of all the ads and AI garbage that's been encroaching more and more since Windows 10. Please look more deeply into whether or not Proton or Wine CAN run the programs you want before proceeding with it, don't take my word for it as I barely know what I'm talking about.

genuinely wild to me when I go to someone's house and we watch TV or listen to music or something and there are ads. I haven't seen an ad in my home since 2005. what do you mean you haven't set up multiple layers of digital infrastructure to banish corporate messaging to oblivion before it manifests? listen, this is important. this is the 21st century version of carving sigils on the wall to deny entry to demons or wearing bells to ward off the Unseelie. come on give me your router admin password and I'll show you how to cast a protective spell of Get Thee Tae Fuck, Capital
