Ideas

Starting points for projects using the modules.

For the team-process side of engineering work, being more proactive at work is a separate reference on organizing and reviewing work.

Before an idea becomes a specification

One sentence determines everything: what is the smallest thing the image must distinguish, at what distance, under what light, and how many pixels does the processing need across it.

Projects that write it first specify quickly. Projects that write it last assemble a system from reassuring numbers.

The technical material

Choosing · Optics · Integrating · Evaluating

For broader technical context, see NI.

Forty-two pages, generic and applicable to any module from any supplier — written that way deliberately, because a reader who can specify properly can compare properly.

The ranges

Camera modules and RF modules.

Where projects go wrong

Choosing on the sensor and discovering the optics. The commonest sequence, and it produces a module that resolves beautifully at the wrong distance.

Testing under office light and deploying under a skylight, where the dynamic range of the real scene defeats a sensor that was never asked about it.

Ignoring heat. A sensor running continuously warms, and noise rises with temperature — invisible on a bench and obvious in an enclosure.

And treating the interface as a detail. A module whose output the processor cannot accept is a module that does not work, whatever its image quality.

The cheapest useful step

An evaluation kit, an afternoon, and the real part.

Not to confirm the module produces an image — it will — but to find out whether the thing you need to see is legible at your distance under your light.
