Solder & Signal Projects

Here’s the plan: I’m building a complete set of DIY electronics instruments — and sharing each step. This page is your roadmap. Most projects start simple and build on earlier ones, so feel free to explore or follow in order. Some are built. Some are still coming.

🧰 Power & Setup

Start here. These tools power your bench and give you a place to experiment safely.

• A Replaceable-Battery Power Supply (RBPS)
• A Stable Workbench (SWB)
• A Flexible Breadboard

Test Projects

Before bread-boarding circuits we're going to build, we need to get used to the process, so let's build some test circuits (and learn a little electronics at the same time).

• Varible resistor (potentiometer)
• Capacitors, series and parallel
• Kirchoff's laws
• Capacitor timer circuit
• Resistors and capacitors
• Other circuits (TBD)

🔍 Basic DC Measurement

Measure voltage, current, and resistance — the core skills of analog electronics.

• DC Voltmeter (single + selectable range)
• Ammeter (single + selectable range)
• Ohmmeter (single + selectable range)

📻 Analog Tools & Signal Flow

These help you visualize and trace signals through your circuits.

• Signal Tracer
• Capacitance Meter (single + selectable range)
• Inductance Meter (single + selectable range)
• Component Checker (Diodes, Transistors, LEDs, etc.)

🧪 Composite Tools

Combine multiple measurements into one rugged enclosure — a benchmark project later in the series.

• Consolidated Bench Meter

⚡ AC & Audio Tools

Measure and generate high-voltage and high-frequency signals, including AC line voltage and audio.

• 120V AC Voltmeter (single + selectable range)
• Audio Signal Generator
• Frequency Generator (single + variable range)
• Frequency Analyzer (single + variable range)

⏱️ Timing & Digital Tools

Explore signal behavior over time — plus simple digital tools for logic probing.

• Analog Timer
• Digital Timer
• Square Wave Generator
• Pulse Generator
• Logic Probe

📡 Advanced / RF Tools

Basic radio-frequency detection and measurement to support future wireless experiments.

• Simple RF Detector
• Field Strength Meter
