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.

A couple weeks ago our HVAC guy came over and he was asking me about the new thermostat and how all my smart home stuff is working (he’s familiar with my smart home setup - i have a HomeBridge server on an old iMac. I was going to move it over to a raspberry pi but the iMac has been rebooting when we lose power and I’ve not touched it for months and) it’s working perfectly.

After that conversation, i rebooted the iMac, restarted HomeBridge, updated some plugins, whatever, because I hadn’t touched it in months right?

Half my lights aren’t working when I try to turn them on now. The lights that do turn on take about 30-60 seconds.

What have I done?

ESP32

This week I wanted to shed some light on a seemingly unfamiliar tach amongst the general populace. If are into the tech world and have been around microcomputers like the Raspberry Pi then you’ve probably heard of this device, the ESP32. The ESP32 technically isn’t a device, it’s a chip, specifically a low-cost system on a chip (SoC). It provides Wi-Fi and sometimes both, depending on the model, to embedded devices, or IoT devices.

The ESP32 has many common uses, some of these include smart home applications like connecting light switches, thermostats, plugins, and other appliances. It is also used for remote monitoring sensors. With this, you can monitor temperature, humidity, motion, and other statistics of a room or area and send it over the cloud for real-time analysis. My grandpa has one employed just for this same reason and can adjust the temperature and fans of a room depending on the readings he receives.

Now while there are many more common daily life implementations of the ESP32 I think many people think of it for its network penetration capabilities. The ESP32 can conduct Wi-Fi sniffing which captures and analyzes Wi-Fi traffic in transit. With the correct firmware attached, the ESP32 can log unencrypted traffic and identify active devices within a limited range.  ESP32 can also enact Wi-Fi jamming and when paired with its ability to act as a WAP, you now could have users logging into your Wi-Fi instead of the café’s.

This piece of hardware is going to be my next tech project and I'm excited to see what I can learn from it and do with it. I think this will open many doors in the aspect of learning new hands-on material with networks and devices as well as IoT devices.
