About Solder & Signals
Solder & Signals is a hands-on project log covering amateur radio, Meshtastic, SDR, embedded electronics, CAD, antennas, and whatever other technical rabbit hole happens to be on the workbench.
The site started as a way to document projects that were quickly becoming too complicated to keep entirely in notes, screenshots, and scattered conversations. Rather than only showing finished builds, the goal is to document the entire process: the original idea, hardware choices, testing, mistakes, troubleshooting, redesigns, and eventually the solution that worked.
I’m still learning plenty of this as I go. That’s part of the point.
If a display refuses to cooperate, a GPIO pin isn’t what the documentation seemed to imply, an antenna performs differently than expected, or a design needs to go back into CAD for revision, those parts stay in the story too.
What You’ll Find Here
Projects on Solder & Signals currently include:
- Meshtastic nodes and custom hardware
- SDR receivers and networked SDR systems
- E-ink displays and embedded electronics
- Antenna and RF testing
- Custom firmware and electronics modifications
- CAD, 3D printing, and enclosure design
- Workshop projects and tools
- Amateur-radio projects as I continue deeper into the hobby
Some projects become full permanent project pages, while the Blog serves as the development log for ongoing work. Once a project reaches a meaningful milestone, the useful results get consolidated into its main project page.
The Approach
I try to distinguish between:
What I planned
What I tested
What actually worked
That means measurements, firmware versions, hardware revisions, failure modes, and corrections get documented whenever practical.
This isn’t meant to be a collection of perfect builds. It’s a record of figuring out how to make things work.
Why “Solder & Signals”?
Because most of the projects around here eventually involve one or both.
Sometimes a soldering iron solves the problem.
Sometimes an oscilloscope, SDR, NanoVNA, serial log, or several hours of staring at source code does.
And occasionally the solution is realizing the first idea was terrible and starting over.
