▸ Register interest

This board is on the bench. Leave your email and you'll be first in when it ships, and your interest helps decide what we build next.

What you'll build

See the personality of a component. A curve tracer sweeps a voltage and measures the resulting current to plot a part's I-V curve. That curve reveals how diodes, transistors, and other devices actually behave. You'll build the swept DAC and current-sense ADC and plot the results from an ESP32.

It sits on the SENSE track: reading real-world signals and turning voltages, currents, and biopotentials into clean digital data.

The build pipeline

No steps skipped, no black boxes. Each stage is gated on real proof of work: a clean ERC, valid gerbers, a passing bring-up. You finish having actually done the engineering, not just watched it.

Questions

When does this course open?
It's in active production. Join the waitlist and we'll email you the moment it goes live, and the demand signal helps us decide what to build next.
Is it beginner-friendly?
Every stage is explained from first principles. If you can read a schematic, you can follow along.
What will I need to build it?
The course overview will preview for free; the full course is a one-time purchase (no subscription). Building the board for real also needs its bill of materials (listed in the course) and a small PCB order from a fab house. The course walks you through both.
What will I actually learn?
You'll learn reading real-world signals and turning voltages, currents, and biopotentials into clean digital data, plus the full board workflow: schematic capture, layout, DRC, gerber export, ordering, assembly, and bring-up.
