Most makers do not need a perfect process. They need momentum.
This guide gives you a 7-day execution plan to move from rough idea to a testable prototype without getting trapped in tool switching.
Start here: Launch a project on Haitch
If you skip this, your week turns into random exploration.
Goal: turn "cool idea" into an execution brief.
Deliverables:
Prompt pattern:
Help me define a compact desk product for remote workers with max part size 180mm and target prototype budget under $150.
Goal: generate 3 distinct directions before committing to one.
Deliverables:
Decision rule:
Pick one direction by combining user value + build feasibility.
Goal: produce first inspectable geometry.
Deliverables:
Do not over-optimize aesthetics here. Prioritize geometry you can inspect and revise quickly.

Goal: make product behavior testable.
Deliverables:
If your product has no embedded behavior, use Day 4 for design-for-assembly checks instead.
Goal: avoid hidden integration failures.
Deliverables:
This is where many solo projects fail: strong parts, weak system coherence.
Goal: execute one focused revision cycle based on findings.
Deliverables:
Keep revision scope narrow. One strong revision beats five partial ones.
Goal: decide if you are ready to prototype physically.
Ship criteria:
If criteria are met, move to physical prototype.
If not, repeat Days 5-7 once with tighter scope.
1. Starting with details instead of constraints
Fix: lock 3 constraints on Day 1.
2. Picking first concept too early
Fix: force 3 directions on Day 2.
3. CAD perfectionism on first pass
Fix: ship inspectable geometry first, polish later.
4. No system check before prototype
Fix: do Day 5 every cycle.
| Stage | Target Time |
|---|---:|
| Product framing | 2-3h |
| Concept exploration | 4-6h |
| CAD baseline | 6-10h |
| Firmware baseline | 4-8h |
| System sanity + revision | 6-10h |
| Final prototype decision | 1-2h |
Total: roughly 23-39 focused hours in one week.
For comparison and platform selection, use:
For many small-scope products, yes. The key is disciplined scope and one revision cycle, not endless exploration.
You can still run this workflow by focusing on concept clarity and using AI-assisted guidance for technical artifacts.
Start in Canvas when intent is still fuzzy. Start in CAD when requirements are already clear.
Day 5. System sanity checks prevent expensive prototype mistakes.
Treat the first week as a throughput test, not a perfection sprint.
If you can keep context connected from concept to tangible artifact, your prototype velocity will compound.
