Browser exercises + source-guided hardware handoff
Start at stage 1 if the area is new to you, or choose a later stage if you can already produce its earlier deliverables. The browser exercises let you practise without buying hardware or paying for an AI tool.
CAD downloads are OpenSCAD source models, not ready-to-print machine instructions. Inspect and export the model in compatible software, then prepare it for the intended process. Data and firmware exercises use controlled examples; they do not connect a live API or flash a board.
The last stage is a source-guided handoff. Read the linked project's exact hardware, software and build requirements before buying parts. The three paths develop related skills but are not a verified bill of materials for the illustrated desk display.
Record your starting point and next step →Create a parametric model sized to your needs.
Deliverable: Parametric model (.scad)Add hole spacing and check edge clearances.
Deliverable: Mounting plate modelConfigure a real storage system and record the fit.
Deliverable: Gridfinity configurationHandle failed requests without losing context.
Deliverable: Resilient data adapterAdapt reliable data for a real printer project.
Deliverable: Receipt + print specificationTrace the SmartKnob source and plan a first change.
Deliverable: SmartKnob source mapA fitted part. Reliable information. Responsive control.
Combine what you learned in a build with a purpose. Use the source-guided handoffs, record your decisions and check the physical result.
Plan your build →
A useful idea does not need to start with a circuit diagram or a CAD file. Describe what you wish an object could do, then break it into a few smaller jobs.
Turn your idea into a first experiment →“A desk object that shows when I need to leave.” Who is it for, what does it notice and what should happen?
Try sample travel data on a screen before building an enclosure. A sketch, cardboard model or simulated input can answer a real question.
Connect a live source, add a physical control, then make it fit your space. Learn, borrow, adapt or ask for help at each step.
Choose a question that interests you. Each brief shows the skills to build towards, a small experiment and a way to judge the result. Use the linked lessons if the starting point is new to you.
Starting pointStart when you can change a parametric model and measure a physical part.
Try itChoose three objects with different dimensions. Define the dimensions that change and the constraints that must stay fixed. Generate three variants, then make a small fit coupon before a full part.
Make something you can reviewA parameter table, three model variants and a measured fit record.
Judge the resultDoes each variant preserve wall thickness, clearances and mounting access? Record failed fits as well as successful ones.
Use the Gridfinity handoff →Starting pointStart when you can parse a reading and handle stale or failed data.
Try itCombine two relevant signals, such as a local reading and a forecast. Write a rule for what the display should show when they agree, disagree or become unavailable. Begin with saved responses.
Make something you can reviewA decision table, sample cases and an output prototype.
Judge the resultCan someone explain the display without you? Is uncertainty visible? Compare the rule with a simple single-source version.
Explore connected data →Starting pointStart when you understand non-blocking input and can trace the source of a controller.
Try itWrite down the device states and allowed transitions. Simulate a missing reading, repeated button presses and a restart before connecting moving parts. Give every state an observable result.
Make something you can reviewA state diagram, event log and recovery checklist.
Judge the resultDoes it recover to a known state without repeated unintended actions? Keep manual control available.
Trace a real controller →Explore these sources, then bring back an idea or a documented result. A source listing is not a CAIBI assessment of everything it publishes.
Browse hardware projects, tutorials and maker demonstrations. Evidence and completeness vary by submission.
