About the Smartbag optics PCB

Smartbag optics is an open source PCB design by claudiofin, published on GitHub under the MIT license. It is a 2-layer board measuring 134 × 12 mm, with 13 components from 7 distinct parts.

Other key parts include the VL53L1CXV0FY/1. By type, the board carries 4 diodes, 4 resistors, 2 connectors, 2 capacitors and 1 IC.

It belongs with the sensors designs in this gallery.

From the project

Tagless smart insert for a handbag: recognises its contents with an IR camera, 60 GHz radar and a 96-taxel FSR floor. PCB, CAD, renders and films all generated by script (KiCad -> CadQuery -> Blender).

A removable smart insert for a handbag that recognises what is inside it — without putting a tag on anything.

Everything in this repo is generated by script: the PCB, the CAD, the renders, the films. One command runs the whole chain, from KiCad to a finished MP4.

This is a design study. Some of it is now checked by machine; none of it has been built.

⚠️ The last two lines are printed on every run on purpose — and they are the two findings that rewrote the board. The feed loss deleted the 60 GHz copper and split one transceiver into two sensors; the charging analysis added a thermistor and…
