Nexus Workshops · Lisbon, Iowa

Turn curiosity into capability.

Nexus runs small, hands-on workshops where young people learn modern technology as a craft, work with the same real tools and real code working engineers use, and find out for themselves whether engineering is a fit. Everyone walks out having built something real—and understanding how it works.

Nexus Workshops
What This Is

Most coding programs teach a narrow slice through a sandbox. Nexus teaches real engineering as a craft—hardware, software, networks, and everything between—through small workshops, real tools, and projects that actually work when you're done.

Engineering is a craft, and like any craft it fits some people beautifully and leaves others cold—and both of those are completely fine. Someone who tries it and decides it isn't a fit has still learned something genuinely valuable: a little more about what does.

So Nexus keeps it honest. Workshops are a hands-on look at what this work actually is—the real tools, the real thinking, the real satisfaction of making something work. Each person gets to try the craft on and find out, for real, whether it clicks. No pressure to become an engineer.

The short version

Come find out if engineering is for you. No pressure to become an engineer—just a genuine chance to discover the craft and pick up skills that travel anywhere.

What you can explore

The whole development spectrum.

Workshops are built around the learner's interests. Pick a discipline, or mix several. Each area maps to real projects you can build, real tools used by working engineers, and real careers you might one day pursue.

01

Embedded Systems

Microcontrollers, sensors, motors, and firmware. The code that runs inside everything from a coffee maker to a satellite.

e.g. blink an LED → build a robot
02

Signal & RF

How information travels as waves—radio, audio, light. The physics of communication and the math that makes it work.

e.g. build a wireless link
03

Web Development

Frontend, backend, full-stack. From a static page to a database-driven app that serves real users.

e.g. ship a working website
04

Mobile Apps

iOS and Android, native and cross-platform. The whole journey from "I have an idea" to "it's on my phone."

e.g. an app that runs on your phone
05

Networking

How computers talk to each other. Protocols, sockets, packets—the invisible plumbing of the internet, made visible.

e.g. two devices exchanging data
06

Game Design

2D and 3D games, mechanics, physics, and the engines underneath. From paddle-and-ball to something genuinely fun.

e.g. a game you built and can play
07

Robotics

Hardware and software working together. Motors, sensors, control loops—and the code that makes them act with purpose.

e.g. a robot that follows a line
08

Systems & More

Architecture, design, integration—plus signal processing, data, security, and whatever else the workshop calls for.

e.g. designed around your interest
The Developer Spectrum poster by Nexus Workshops
The Nexus Shop · The Developer Spectrum

See the whole field before choosing a path.

Computing is one of the widest fields there is, and from the outside it can look like a single job. The Developer Spectrum lays it out on one line, from designing the physical machine to running the systems built on top of it, so every degree, job, and technology has a place a student can point to.

It grew out of years in the classroom, helping students see what was out there and where their own curiosity fit. It has been the opening conversation in workshops and mentoring ever since.

What a degree really opens up

Electrical engineering, computer engineering, computer science, software engineering, IT, and data science each cover a stretch of the field, and those stretches overlap. Students see what each program prepares them for and where graduates of different majors land in the same jobs.

Where the classroom meets the tools

Every language and technology sits at the station where it does its work, right alongside the degree that leads there. Verilog, C, Python, SQL, Kubernetes: each one has an address, and the coursework finally connects to something real.

Many lenses on one problem

An RF engineer, a back-end developer, and a network administrator can look at the same system and see three different things. The spectrum shows why: knowledge, education, and experience shape the questions each person asks.

What a systems engineer carries

One role spans the whole width. The systems engineer is expert in a few stations, literate in all of them, and starts from the need and the shape of the whole system before any code is written.

How much math, and which kind

Calculus and electromagnetics at the hardware end, logic and counting in the middle, statistics toward data, and arithmetic and budgets where systems run. Students see the math that matches the path they are drawn to.

Breadth, depth, and where to start

At a small company one engineer covers a dozen stations; at a large one, six specialists split the same ground. The poster helps a student weigh the two and see why breadth early pays off for a lifetime.

A conversation starter for a classroom, a lab, a robotics team room, or the wall of a student deciding what to study next.

How Nexus is different

Four things that set us apart.

01

Small cohorts

Workshops are intentionally small. The instructor knows each learner, watches how each one thinks, and adjusts the pace to fit.

02

Real tools

No proprietary platforms or sandbox languages. Learners use the actual tools and languages working engineers use every day.

03

Build to keep

Every workshop ends with something real—hardware, code, or an app—that students take home and can show off.

04

An honest fit

This is a chance to try the craft on. If it clicks, there's a whole spectrum to explore. If it doesn't, that's a real answer too.

The Instructor

Taught by Eric Ratliff.

Nearly thirty years building systems that have to work the first time—from radios in space to machine learning in the field. The kind of range that means whatever a learner wants to build, there's deep, real experience behind the teaching.

The Learning Hub · nxlearn.net

A whole toolbox for learners.

Beyond the workshops, Nexus builds and publishes open-source tools, field guides, and references at nxlearn.net—the technical home base for learners who want to keep going. Free to use, study, and build on.

More tools and guides land regularly. Same philosophy: small, sharp, focused. Visit nxlearn.net
Get in Touch

Curious whether it's a fit?

Cohorts are small and sessions are set on request. Call, text, or email with questions or to sign up—and if you'd like, we can meet for a few minutes first, no commitment, so you can get a feel for it before deciding.
