# [DIY Kit Name] — Build Guide
|
||||
|
||||
**Version:** [v1.0]
|
||||
**Date:** [YYYY-MM-DD]
|
||||
**Author:** [Name / Contact]
|
||||
|
||||
---
|
||||
|
||||
## 1. Introduction
|
||||
- What this kit does (short description).
|
||||
- Skill level required (Beginner / Intermediate / Advanced).
|
||||
- Estimated build time: [X hours].
|
||||
- Tools required: [Soldering iron, multimeter, etc.].
|
||||
|
||||
---
|
||||
|
||||
## 2. Circuit Description
|
||||
### 2.1 General Idea
|
||||
- Short explanation of the concept.
|
||||
- Example: *The kit demonstrates low-power control using an ATtiny85 microcontroller. It blinks an LED in Morse code and sleeps when ambient light is detected.*
|
||||
|
||||
### 2.2 Annotated Schematic
|
||||
*(Insert schematic image exported from KiCad, e.g., as PNG or PDF)*
|
||||
|
||||
Use numbered blocks for explanation. Example:
|
||||
|
||||
**Figure 1: Schematic with annotation numbers**
|
||||
|
||||
| Block | Circuit Section | Description |
|
||||
|:-----:|:------------------|:------------------------------------------------------------------------------------------------------|
|
||||
| 1 | Power Supply | 2×AA batteries → DC/DC regulator (U1) → 5 V rail. Decoupling capacitors (C1, C2) smooth the voltage. |
|
||||
| 2 | Controller | ATtiny85 (U2) running firmware. Pull-up resistors (R1, R2) ensure stable inputs. |
|
||||
| 3 | LED Output | LED D1 driven by PB0. Current limited by R3 (330 Ω). |
|
||||
| 4 | Light Sensor | LED D2 reverse biased → generates photocurrent. Read on PB2. |
|
||||
| 5 | Programming Header| ISP 6-pin header for flashing firmware. |
|
||||
| 6 | Test Points | Labeled pads J1–J3 for debugging with a multimeter. |
|
||||
|
||||
*(Link to the KiCad schematic file in Git repo, e.g.: [GitHub/Gitea link])*
|
||||
|
||||
### 2.3 Functional Flow
|
||||
- Add a block diagram showing logic signal flow (KiCad → export block diagram or draw in Mermaid).
|
||||
- Example: *Battery → DC/DC → ATtiny85 → LED driver → LED.*
|
||||
|
||||

|
||||
|
||||
## 3. Mechanical Parts
|
||||
### 3.1 2D CAD Files
|
||||
- Mechanical drawings in DXF for front panel / housing.
|
||||

|
||||
|
||||
### 3.2 3D Models
|
||||
- STL/STEP files for 3D printing, if available.
|
||||
- Assembly orientation, support recommendations.

We use two thresholds:

T_hold (smaller): below -> treat as neutral and HOLD state
|

T_enter (larger): above -> allow direction change (set by sign)

|

Behavior:

If |diff| <= T_hold : hold direction
|

If |diff| >= T_enter: set direction by sign

Else (between) : hold direction

Presets (implemented as multipliers of the calibrated VdiffThreshold):

T_hold = 1.0 * VdiffThreshold
