LCA2019 E-ALE Floral Bonnet

Raspberry Pi Zero sensor-bonnet hardware kit for Apprentice Linux Engineer labs

linux.conf.au 2019 hosted the Apprentice Linux Engineer tutorial track in Christchurch, where lab participation required a purchased Floral Bonnet board for Raspberry Pi Zero hands-on embedded-Linux exercises.

Why It Mattered

The Floral Bonnet extends Oceania coverage beyond classic name badges: it was a real event hardware artifact used by attendees to learn Linux drivers, GPIO, SPI, I2C, Bluetooth, IoT, and hardware/software bring-up in an LCA track.

Hardware

Official LCA2019 and E-ALE pages document a Raspberry Pi Zero WH lab platform plus the Floral Bonnet sensor package, with CP2102 serial-over-USB console, SPI SSD1306 128x64 OLED screen, I2C BME280-class pressure/temperature sensor, I2C TSL2561 light sensor, GPIO push button, and GPIO/PWM-connected tricolor LED. The kit was sold at LCA for NZD 20 after ARM sponsorship reduced the original cost.

Software & Apps

The public seminar sequence covered a Floral Bonnet walkthrough, U-Boot, Bluetooth, GPIO/libgpiod, SPI/spidev, I2C/i2cdev, IoT/cloud, and IoT security. The source trail proves hands-on labs and driver-writing context, but this pass does not claim a recovered firmware repository for the board itself.

Lore

E-ALE described the bonnet as hastily created in time for LCA so attendees would have sensors, LEDs, and buttons to play with during the seminar series. Attendees with a Floral Bonnet were given first access to limited classroom seats.

Operational history

Issues & Camp Impact

hardware archive gap note

The recovered source trail documents the board role, Raspberry Pi Zero WH target, major peripherals, lab use, and kit price, but this pass did not recover schematic, PCB, BOM, firmware, or exact sensor-part correction beyond the page text.

The entry keeps claims to the official component list and training context while avoiding unsupported board-revision, driver-source, or manufacturing-quantity details.

Confidence: source-backed but incomplete
Status: needs board repository recovery
Timeframe: 2019 hardware-kit archive pass
Source note: LCA2019 E-ALE page, E-ALE Linux.conf.au 2019 page, and Floral Bonnet walkthrough.

missing rights-cleared image note

No Floral Bonnet image is published because the recovered E-ALE page images have not been paired with complete image reuse rights, attribution, source URL, and processing notes for catalogue publication.

The record remains source-backed and image-free rather than copying seminar-page photos or publishing generated imagery.

Confidence: local project policy
Status: needs licensed original replacement
Timeframe: current catalogue build
Source note: badge.gallery image policy and E-ALE LCA2019 source pages.

training-artifact classification note

The source trail proves a Floral Bonnet board used for LCA2019 E-ALE labs, but not a conference-wide attendee badge.

The entry is modeled as a hardware training kit in the linux.conf.au/Oceania lineage rather than an official admission badge.

Confidence: primary source
Status: documented
Timeframe: 2019 E-ALE track
Source note: LCA2019 E-ALE page and E-ALE Floral Bonnet pages.
