== The boys Induction Furnace ==

= Induction Furnace Development Update =
We have made significant progress on the parametric Induction Furnace model in FreeCAD. This update covers the high-LOD enhancements, a focused core generator, a real-world Bill of Materials, and step-by-step build instructions.
== Model Overview ==
We have developed two generator scripts to cater to different needs:
=== Full System Model ===
* '''Script:''' `generators/machines.py`
* '''Command:''' `python3 cli.py furnace`
* '''Description:''' A complete industrial setup including the structural frame, concrete platform, safety railings, hydraulic tilting mechanism, and full control panel.
* '''High-LOD Features:'''
Hydraulics: Hydraulic Power Unit (HPU) with reservoir, motor, valve block, and hoses connecting to the tilt cylinder.
Electronics: Detailed ZVS Driver module with PCB, heatsinks, capacitor bank, and choke inductors mounted on an open-frame rack.
Cooling: Explicit water cooling loop with pump, radiator, fan, tank, and hoses.
Hardware: Hex bolt heads at frame joints and pivot points.
Casting: Double-crucible system (Inner Melting Pot + Outer Chamber) with a pouring spout and steel ramp.

=== Focused Core Model ===
* '''Script:''' `generators/induction_furnace_core.py`
* '''Command:''' `python3 cli.py furnace-core`
* '''Description:''' A simplified model focusing strictly on the functional components required for melting.
* '''Components:'''
Induction Circuit (ZVS, Bus Bars)
Heat Dissipation System (Radiator, Pump, Tank)
Coil (Copper Tubing)
Melt Chamber (Outer Crucible)
Feeder (Hopper)
Crucible (Inner Pot)

== Bill of Materials (BOM) ==
We have sourced real-world parts for the core components. Prices are estimates.

Worked on the house. Got Text-To-Cad working. Learning about repositories per [[OSE Part Library]], [[CAD Repositories]], [[JacksonL's CAD Work]], [[Talk:Induction Furnace]]

=Saturday, Dec 6, 2025=
Built a text to cad environment with antigravity, will upgrade. Working on systems thinking now.Okay that was kinda fruitless. Going back to upgrading the text to cad environment for a more integrated engineering environment or something

I have a hypothesis about the "best way to do creation" based on your current setup and our previous discussions on biomimicry.

Hypothesis: The "Living Model" Paradigm

Currently, you are doing Imperative Injection: sending raw code strings to FreeCAD to "do X". This is like surgery—effective but invasive and brittle.

The "Best Way" is likely Declarative Homeostasis (Biomimetic approach):

DNA (The Spec): Define what you want (e.g., a TowerConfig object or JSON), not how to build it.
Growth (The Generator): A system inside FreeCAD that reads the DNA and "grows" the geometry.
Homeostasis (Idempotency): The system checks: "Does the current 3D world match the DNA?"
If yes: Do nothing (Energy efficient).
If no: Heal/Update the difference (Adaptation).
Practical Implication for Antigravity: Instead of complete_tower.py sending a script string, it should send a signal or gene (parameters) to a TowerBuilder class already resident in the FreeCAD environment.

Would you like to explore this "Living Model" architecture? I can help you refactor the tower scripts to demonstrate this "Growth" capability.

Long day workin on the hangar. Concrete pour

=Thursday, Dec 4, 2025=
Updated the website with Roof Numbering, Added dimensions button, made [[Antigravity Tutorial]], working on developing the full tech stack,

=Wednesday, Dec 3, 2025=
[[OpenProject]], Updated the website. Recorded an antigravity tutorial but my microphone was off haha. First thing tomorrow.
Adding BOM

=Tuesday, Dec 2, 2025=
Working on the modules, working on the tool/website. Learning about [[Full Stack Development]]. Tools like [[Asana]], [[Notion]]. And their Open-Source alternatives. Found one for asana - [[OpenProject]]

Trying to set things up to improve OSE. Seems like we need some sort of central nervous system. Somewhere people can express their needs, track projects, chat, whatever.
Working on it!

=Monday, Dec 1, 2025=
[[SH7 CAD Alternative]], Worked on the hangar a little bit. Mostly worked on the website though (the website is the cad alternative)
8am-3:30am

=Sunday, Nov 30, 2025=
On the seventh day, god rested... or something. Too tired to work on the hanger. Working on the website instead.

=Saturday, Nov 29, 2025=
Worked on the hangar until 7:45-6pm. 6pm Meeting. Worked on the website until 1:20am. Bed

=Friday, Nov 28, 2025=
Working on the hanger. Inside.
[[Google Antigravity]]. I really think we could use this to solve most of our problems :)

=Thursday, Nov 27, 2025=
Working on the hanger. Outside.
Birthday :) Nini made me a cake. Thanksgiving ;]

=Wednesday, Nov 26, 2025=
Working on the hanger. Outside.

Working on the hanger. Outside.
Met Nini, Tony Shay, Brenno, Sage, Joel.

=Sunday, Nov 23, 2025=
Working on the hanger.
Starting to learn. Learned the difference between an impact drill and a regular one. Learned the trick to suck in wood with screws and blocks.
Met Aidan, Ben, Jeremy, Ena, Hannah, Bo, Nick, Roy.

=Saturday, Nov 22, 2025=
Flew in to KCI, got set up at the Hablab

=Friday, Nov 21, 2025=
Finally got [[Aider-Desk]] installed. Seems like it works with [[Ollama]] :)

Started the day trying to get automation going. Seems like there is a whole world out there of this stuff.
Sometimes I see it called "Workflows". There is a lot of stuff being made on this. There is [[n8n]] which is open source but not free I believe. There is certainly an open source free alternative, but I am hardstuck because I don't really understand coding. So I thought okay well it's fine to not understand coding if I can get something like and AI assistant that can handle the coding for me. Found a few online. People recommend [[Windsurf]] except it's not open source or free... seems like it's a part of [[Devin]] which looks interesting but... yeah not open source or free.
Tried to get [[Zed]] but I just doesn't open after download. Started trying to get [[Aider]] but I really don't like blasting code into my terminal that I don't understand.

TL;DR is I think I just need to go back to first principles and just learn how linux works instead of just reaching for the best tools.

Found this in a youtube video: [[LinuxJourney]]

=Tuesday, Nov 18, 2025=
[[Docker]], [[Khoj]]

=Monday, Nov 17, 2025=
[[Ollama]], [[OpenSCAD]]

=Saturday, Nov 15, 2025=
Hello all! I wanted to share information about my new laptop I bought!
It's called [[System76]]. Pre-built linux machine that is open source and puts your privacy first c:
Highly recommend!

=Monday, Oct 21, 2025=
[[Systems Architecture Model (SAM)]], [[MBSE]] (Model-Based Systems Engineering), [[Obsidian]], [[Fireflies.ai]] ...

Thinking about how to be effective. Considering automating/fusing these together.
Some workflow where recorded audio (Fireflies) or text could be woven into the SAM and MBSE framework. Allowing collaborative real-time editing and suggestion mapping. Obsidian could be used in the process to collect thoughts before pushing wider packages through to the more complex modelling. Also just found out about Jeffrey Sachs, what a rockstar. Stuck at work 9-5 so I wanted to put my thoughts out there and hope. Also, you can ask GPT to write mediawiki for you (phew!).

All the best.
Jackson

Cleaning PC, creating backups, preparing to dualboot Linux & Windows.

=Thursday, Oct 16, 2025=
Getting involved! Checked out Github. Ordered a USB for OSE Linux 3. Will boot up and attempt Developer Test.

Jackson Here!

I made a little website to help myself out in the field! Works on mobile.

[[File:Tech Stack.jpg|thumb|Full* Tech Stack]]
Made this image with Google Flow! Very good for creating infographics, highly accurate and intelligent.

Going to leave more information on the full Tech Stack we're building

Antigravity - Vibe coding on steroids - Build anything

Short Tutorial:
https://www.youtube.com/watch?v=itXIEIMciKQ&feature=youtu.be

OpenProject - Project Management - Assign yourself tasks i.e. "I am building module 5". Handles all sorts of stuff, shopping list, whatever you want

Still hashing out the rest of the details. Working on hosting OpenProject
