ToorCamp 2018 Badge

MSP430 electronic jar-of-fireflies camp badge

ToorCamp 2018's badge is preserved as a Great Scott Gadgets and OSH Park sponsored electronic jar of fireflies: a soldering-station badge kit built around an MSP430G2211, six green through-hole LEDs, CR2032 power, and open design/firmware files.

Why It Mattered

It adds ToorCamp as a North American outdoor hacker-camp lineage and captures a badge that explicitly bridges camp identity, hands-on assembly, low-power LED behavior, and open repository publication rather than only conference-hall badgelife.

Hardware

The Great Scott Gadgets archive lists a CR2032 SMD battery holder, six green diffused 3 mm LEDs, four 100 ohm resistors, one 22k resistor, one 8.2M resistor, and a Texas Instruments MSP430G2211IN14 16-bit microcontroller, with hardware design files and a BOM in the public repository.

Software & Apps

The repository contains firmware source for the MSP430 badge, while the project page notes that firmware reflashing help was available through Great Scott Gadgets. The public record supports source-level firmware availability but does not claim a richer app platform.

Lore

Attendees assembled the badge into a regular-mouth canning jar such as a 4 oz Ball jar, turning a simple wearable PCB into a small firefly scene. The camp itself was at Doe Bay on Orcas Island and openly identifies as a hacker camp inspired by the Netherlands and Germany camp traditions.

Issues & Camp Impact

firmware-source scope caveat note

The public repository proves hardware and firmware source availability, but this pass does not audit every source file, firmware build, power profile, or attendee modification.

The record preserves verified hardware/software surfaces while leaving deeper MSP430 firmware archaeology for later work.

Confidence: repository review and project page
Status: documented with caution
Timeframe: current ToorCamp 2018 pass
Source note: Great Scott Gadgets badge page and toorcamp2018badge repository.

image provenance upgrade note

The ToorCamp 2018 visual uses the BSD-licensed repository JPEG embedded in the Great Scott Gadgets README as the Jar of Fireflies badge image.

The public badge page, image archive, and API point at an original repository photo with source URL, license, attribution, and processing notes preserved.

Confidence: repository license and README image evidence
Status: licensed original replacement applied
Timeframe: current catalogue build
Source note: toorcamp2018badge README, LICENSE, and image provenance record.
