Instruments that read the invisible.
A field of one hundred thousand particles is drifting behind this page. It only resolves into structure where you slow down. Scroll to take a reading.

01 · the wake
Every force leaves a wake. We build the sensors that make the wake legible.
Wind, current, charge, pressure: none of them are visible, and none of them ever will be. The particle is. SONDE reads a field the only way a field can be read, by watching what it moves.
02 · the reading
It reads where you dwell.
Move fast and the field is only drift, a hundred thousand particles finding their own way. Slow down and the instrument takes a reading: the drift organises, the source resolves, structure appears. The measurement is the attention.

03 · the instruments
Four sensors, one field.
Each reads a different invisible. Change the source above and watch the field answer to a different instrument.
SONDE-D
dipole probe
Maps the pull between two charges. Reads polarity, gradient, and the null line where the two exactly cancel.
- reads
- polarity · gradient · null-line
- range
- ±40 field units
- output
- live vector
SONDE-V
vortex meter
Traces rotation. Circulation, vorticity, and the still eye at the centre where the field turns on itself.
- reads
- circulation · vorticity · eye
- range
- 0 to 12 rad/s
- output
- live scalar
SONDE-L
laminar gauge
Follows steady flow. Direction, shear, and the thin sheets that slide past one another without ever mixing.
- reads
- direction · shear · sheets
- range
- 0 to 8 units/s
- output
- flow field
SONDE-C
convergence cell
Finds where everything is drawn to one point. Sinks, wells, and the quiet moment before a collapse.
- reads
- sinks · wells · collapse
- range
- full domain
- output
- density map
04 · field notes
“We stopped trying to photograph the wind. We built something that lets you feel it move.”

Tell us which invisible you need to see.
We will build the sonde that reads it. One field, one instrument, one reading at a time.
