Intervening Before the Amputation Happens
◆ THE THESIS OF THIS STUDY

Every other corpus study intervenes on adults already trained, already misnamed, already excluded. This study intervenes before. The amputation documented in "The Invisible Amputation" has an origin point: the year-7 classroom, the 12-year-old who has never seen a machine obey their instructions. This point is accessible — without public budget, without new institution, without waiting for the state. It requires a teacher, an Arduino starter kit at €35, and the collective decision of a few colleagues to put €10 a month into a shared fund.

SECTION 1 · THE BIFURCATION MOMENT — WHY SECONDARY SCHOOL
AT 12, NOT 23 — THE MOMENT AMPUTATION BEGINS

The amputation of women from the infrastructure body does not begin at recruitment. It does not begin at university. It begins in a year-7 classroom, when a 12-year-old child decides — often without realising it — that machines and circuits are not for them. Or for her. This bifurcation moment is silent, invisible, and decisive. It is also accessible to an intervention that costs almost nothing.

◆ WHAT THE 12-YEAR-OLD BRAIN DOES THAT THE 23-YEAR-OLD BRAIN NO LONGER DOES

Between 10 and 15, the brain is in a phase of maximum plasticity for learning through physical manipulation. A child who touches an object, makes it work, understands why it works through trial and error — that child encodes a relationship with the physical world that an adult can no longer encode with the same depth.

This is not pedagogical nostalgia — it is neuroscience. The infrastructure engineer who knows how to "hear" an anomaly in fan noise often developed this sense through early contact with physical machines — a mechanic father, an electrician grandfather, a technology teacher who dismantled appliances. When this contact has not happened, the physical layer remains abstract for life. It can be learned later — but with more effort and less depth.

◆ THE EXACT MOMENT AMPUTATION IS DECIDED

Amputation is not decided through a deliberate act. It is decided through an absence: no equipment in technology class (kits broken or never ordered), no project that produces something physical, no adult who explicitly says "you too can make this work". In this void, ambient stereotypes fill the space — boys occupy the available equipment, girls orient toward what remains. The pedagogical void is the first amputation mechanism.

◆ NASSIHA — DEAMPUTATION AT THE SOURCE IS NOT A DIVERSITY POLICY

This is not an awareness programme. It is not an institutional "girls who code". It is simply a teacher who brings physical equipment to class and structures the activity so that every student — girl or boy — has a moment alone with the machine. That moment alone, repeated, is the deamputation.

SECTION 2 · THE ARDUINO AS FOUNDING OBJECT
€35 · PHYSICAL AND PROGRAMMABLE SIMULTANEOUSLY · THE LED THAT CHANGES EVERYTHING

The Arduino is not a toy. It is not a professional tool either. It is something rarer: an object that tells the child that their instructions in human language can move the physical world. An LED blinking at the rhythm they programmed is a revelation — not a gadget. It is proof that code is not abstract magic: it is electricity controlled by thought.

◆ WHY ARDUINO — AND NOT SCRATCH, NOT PYTHON, NOT A SIMULATOR

Scratch and Python on computer are valuable tools — but they stay on the screen. The child understands the logic, not the substrate. Arduino adds the physical dimension: the code leaves the computer and enters the world. The LED lights up. The motor turns. The temperature sensor reads the heat from their hand.

This leap — from screen to world — is exactly the leap the corpus defends from the start: "the metal precedes the code". Arduino at school is the first practical expression of this thesis. The child who has experienced this leap at 12 understands much more easily later why bare-metal is not an obsolete technology — it is the substrate of everything.

◆ WHAT AN ARDUINO STARTER KIT AT €35 ALLOWS IN CLASS

Session 1 — The LED: light and extinguish an LED by programme. Understand the electrical circuit, resistance, current. The physics teacher explains the circuit. The maths teacher explains the if/else condition. The student executes.

Session 2 — The rhythm: blink the LED at a programmed rhythm (delays, loops). Introduction to for and while loops. Maths says the logic. Physics says the electricity. Technology says the wiring.

Session 3 — The sensor: read ambient temperature with a sensor, display on serial monitor. Introduction to variables and inputs. The student understands that the machine "sees" the physical world.

Session 4 — The project: alarm system if temperature exceeds a threshold, red LED lights up. First complete project: sensor + condition + action. Full student autonomy on the realisation.

SECTION 3 · THE POOLED BUDGET — THE CONCRETE MECHANICS
€10/MONTH PER TEACHER · €2,400/YEAR · A REAL ROBOTICS CLASS

The equipment problem in classrooms is not the absence of public budget — it is the absence of collective initiative. A single teacher cannot regularly fund educational equipment. Twenty teachers each contributing €10 per month create a fund of €200/month — €2,400 per year. That is a real robotics class, funded by teachers themselves, available without requesting a single euro from the state.

◆ WHAT €2,400/YEAR BUYS — COMPLETE INVENTORY

Arduino Starter Kits (20 kits at €35): €700 — a class of 20 students, each with their own kit. One-off investment, hardware reusable for 5 years minimum.

Additional components: €300 — sensors (temperature, light, motion), servo motors, LCD screens, Bluetooth modules. Expands possible projects over sessions.

Cables, breadboards, resistors: €100 — consumables to renew annually.

Raspberry Pi (5 units at €80): €400 — for advanced students, more complex projects (web server on Raspberry Pi, surveillance camera, home automation). Introduction to Linux systems.

3D filament printer (1 unit): €300 — to print project casings. The project does not stay on a breadboard — it has a physical body.

Reserve: €600 — for subsequent years, replacements, new ideas. The pooled fund accumulates.

◆ THE FUND MECHANICS — SIMPLE AND ROBUST

Joint account opened in the name of the parents' association (which exists in every school). Automatic monthly transfer from each participating teacher. Purchase decisions voted at a 20-minute monthly meeting. Transparent accounting shared on a common spreadsheet. No new legal structure to create. Not bureaucracy: a monthly transfer and a spreadsheet.

◆ WHY THE POOLED BUDGET — AND NOT A GRANT APPLICATION

This proposal is deliberately independent of any administrative process. No project call. No academic dossier. No application to the local council, regional authority or ministry. These channels exist — and they can complement this arrangement if they succeed. But they take time that children do not have: the year-7 bifurcation does not wait for a ministerial decree.

The pooled budget says one simple thing: we are responsible for what happens in our classrooms. We are not waiting for anyone to act.

The parents' association — a natural complementary lever: parents have a direct and legitimate interest in their children's education. A parents' association that decides to fund digital fabrication equipment for its students is not organising a school fair — it is investing in the technical future of its children. A voluntary contribution of €5 per family from 50 families adds €250 to the annual budget. From 100 families: €500. Without any additional administrative structure. The parents' association already exists in every school — it only requires teachers and parents to decide together that this priority is worth it.

SECTION 4 · THE DISCIPLINE BRIDGE — MATHS, PHYSICS, TECHNOLOGY
THREE TEACHERS AROUND ONE OBJECT — WHAT NONE ALONE CAN GIVE

The key is not the equipment — it is the coordination between disciplines. An Arduino without a disciplinary bridge is a gadget that impresses for two weeks then is forgotten. With the bridge between maths, physics and technology, it is a lasting revelation: the student understands that the abstractions they learn in the morning execute in the physical world in the afternoon. This link is what the corpus calls "the metal precedes the code" — seen in reverse: the code vivifies the metal.

◆ THE MATHS TEACHER — THE ALGORITHM WITHOUT EQUIPMENT

The maths teacher does not need an Arduino to contribute. They introduce the algorithm on paper — in human language, not code. "If the temperature is above 25°C, light the red LED. Otherwise, light the green LED." That is a condition. "Repeat this check 10 times per second." That is a loop. "Create a variable temperature that stores the sensor value." That is a variable.

These concepts — condition, loop, variable, function — are mathematical concepts the maths teacher can naturally introduce in their lessons, with concrete examples drawn from the Arduino activity. The algorithm on paper is the translation into human language of what the code does in machine language. This translation work is the maths teacher's contribution — with no equipment whatsoever.

◆ THE PHYSICS / TECHNOLOGY TEACHER — THE FLESH OF CODE

The physics teacher brings two things: understanding of the electrical circuit — current, voltage, resistance, LED, sensor — and the connection between code and physical world: "when you write digitalWrite(13, HIGH) in your programme, you are sending current into this pin, which passes through this resistor, which powers this LED". The physical causality of code. The student who understands why a resistor is needed before the LED understands something about electricity that code will never tell them.

◆ THE SELF-TAUGHT TEACHER — THE M3ALLEM OF THE SCHOOL

The self-taught teacher — of any subject — who learned Arduino from YouTube on a Sunday afternoon is the M3allem the corpus speaks of. No Arduino certification needed. No expertise required. Just one session ahead of students, and honest about it: "I am discovering with you, we will search together." This posture is pedagogically more powerful than a distant expert.

SECTION 5 · DEAMPUTATION OF GIRLS — THE ACTIVE MECHANISM
WHAT THE TEACHER DOES — OR DOES NOT DO — THAT CHANGES EVERYTHING

Girls do not lose interest in robotics because they lack the ability. They lose interest because nobody explicitly invited them — and in the absence of that invitation, ambient stereotypes fill the space. The teacher who activates the deamputation mechanism does not need to give a speech about equality. They need to do two concrete things.

◆ MECHANISM 1 — THE MOMENT ALONE WITH THE MACHINE

In group activities, boys tend to take the keyboard and the Arduino. Girls tend to observe, take notes, advise. This is not bad faith from either side — it is a social pattern that reproduces automatically if not interrupted.

The minimal interruption: each student has a moment alone with the kit. Not in a group. Alone. They must connect an LED, upload the programme, verify it works. This moment alone is the deamputation. The girl who made an LED blink alone, with her own hands, without help, has an experience nothing can take from her. She has proved to herself that she can make a machine work.

◆ MECHANISM 2 — THE EXPLICIT AND REPEATED INVITATION

Implicit invitation is not enough. "Everyone can participate" says nothing to a 12-year-old girl who has already internalised that robotics is not for her. The invitation must be explicit and repeated: "I want you to try this — not him in your place, you." This is not positive discrimination. It is remedial pedagogy for an imbalance that installed itself before the student even entered the classroom.

◆ THE SCIENTIFIC BASIS — WHAT PSYCHOLOGY SAYS ABOUT THE FEELING OF MAKING

This feeling of satisfaction is not subjective — it is scientifically documented through three distinct phenomena.

The IKEA Effect (Norton, Mochon & Ariely, 2012 — Journal of Consumer Psychology): Four studies on subjects assembling IKEA boxes, folding origami, and building Lego sets demonstrate that individuals value their personal creations as highly as expert creations — even when objectively less well-made. The effort of making produces emotional attachment to the created object. This effect only applies to tasks completed to the end: if the creation is destroyed before completion, the satisfaction disappears. This is why the project must reach the finished object — the engraved part, the completed print, the machine's first movement.

The Self-Creation Effect (Brunneder & Dholakia, 2018 — Marketing Letters): Seven field and laboratory studies show that when a person self-creates a product, they appreciate it more, consume it more mindfully, and experience greater domain-specific and general well-being. This effect is amplified by self-consciousness — the student who knows they made something with their own hands develops a self-esteem that passive consumption does not produce.

The Maker Movement and Subjective Well-Being (Journal of Happiness Studies, 2017): A study of 465 students shows that a "maker" identity — perceiving oneself as someone who makes things — is a significant predictor of subjective well-being. Making activities (sewing, cooking, electronics, DIY) produce a sense of accomplishment and competence that transfers to other life domains.

What this means for the student: when the 13-year-old girl sees her name appear on a piece of wood engraved by the laser she programmed, she does not simply feel pride — she feels a neurological attachment to her own competence. This feeling, once anchored, does not disappear. It becomes the basis of a lasting curiosity about the physical world.

◆ WHAT THE DATA SAYS ABOUT LONG-TERM EFFECTS

Studies on mixed-gender school robotics programmes show that girls who had structured contact with physical robotics in secondary school choose technology pathways at two to three times the rate of those who did not. The effect is not immediate — it is deferred by two to four years. The teacher who puts an Arduino in a 12-year-old girl's hands sees the result at 17, not the next day.

SECTION 6 · THE ECOSYSTEM THAT ALREADY EXISTS — NO NEED TO INVENT
EVERYTHING NEEDED IS ALREADY THERE — IT JUST NEEDS TO BE FOUND

The teacher who wants to start does not need to create anything. They need to find what exists and take ownership of it. The educational Arduino ecosystem is rich, documented, and largely free. The barrier is not the lack of resources — it is the lack of time to find them. This section centralises them.

◆ FREE RESOURCES AVAILABLE TODAY

Arduino Project Hub (projecthub.arduino.cc): thousands of documented projects, from beginner to advanced level. Each project includes code, wiring diagram and explanations. The teacher chooses a project suited to their level and curriculum — and has everything they need.

Arduino official documentation (arduino.cc): official documentation, step-by-step tutorials, references for all functions. Free, maintained, available in multiple languages.

Instructables (instructables.com): collaborative projects documented by their creators. Often more creative and contextualised than official documentation.

YouTube — educational channels: hundreds of 10-20 minute videos explaining each component, each concept, each project. The self-taught teacher learns in two hours what they will teach over two months.

FabLabs and makerspaces: in most medium and large towns, there is a fablab or makerspace that lends equipment, organises workshops, and welcomes school classes. Often free for educational institutions on request.

◆ TEACHERS WHO HAVE ALREADY DONE THIS

Hundreds of secondary school teachers in France and elsewhere have already set up Arduino activities — often alone, often from their own funds, often without institutional support. Their feedback is on teaching forums, in teacher Facebook groups, on personal blogs. These experiences exist — they are just not very visible. Searching "Arduino secondary school teacher experience" yields dozens of concrete testimonies.

SECTION 7 · THE COMPLETE CHAIN — FROM ARDUINO TO TECHNICAL SOVEREIGNTY
THE CHILD WHO BLINKS AN LED AT 12 IS THE BARE-METAL SRE OF 2035

The Opération Dindon corpus documented a chain of consequences starting from cloud and descending to bare-metal competence scarcity, to senior departures, to the absence of women. This study climbs the chain to its furthest upstream point — the year-7 classroom. And shows that every link of this chain is accessible, in both directions.

◆ THE COMPLETE CAUSAL CHAIN

Arduino at school (age 12): first physical contact with an obedient machine. Curiosity installed. Fear of the machine lifted. Girls and boys equal before the kit.

Technology pathway at sixth form (15-18): the student who touched an Arduino chooses a scientific or technological pathway more easily. The door is open because it has already been crossed.

HND / degree-level infrastructure training (18-20): the Foundation of Iron proposed in the corpus. Electricity, physical networks, systems, Kubernetes. The bare-metal base the infrastructure body needs.

Entry into the body (20-23): with the proposed nomenclature — SysOps L2/L3. A clear title, objective criteria, documented progression. A readable door that the girl who did Arduino at 12 can cross without informal network.

Principal SRE (30-35): with Technical Primacy, the Uniform of the Body, Elastic Syntec — a protected, visible body with decision authority. Technical sovereignty is complete.

Senior SRE Transmitter (40+): formalised mentoring, supervised rotation, transmission of tacit knowledge. The cycle restarts — and the 12-year-old girl who blinked an LED is now the master who blinks the LED of another 12-year-old girl.

Technical sovereignty does not begin in a datacentre.
It begins in a year-7 classroom,
when a teacher takes an Arduino out of their bag
and says: "Let's go."
