2026 eChallengeCoin (DEF CON 34)
Independent brass Coin M0 text-adventure and CircuitPython eChallengeCoin planned for DEF CON 34
AoSC's 2026 eChallengeCoin page describes a planned limited run of 40 brass electronic coins, framed as gifts for participants in its Choose Your Own Charity initiative rather than items for sale. It describes a Sara and the Missing Artifacts terminal text adventure, three groups of NeoPixels, a small speaker, one large touch pad for CircuitPython, no battery, 46-gram brass construction, and a Micro-USB serial connection; its form says a $100-or-greater youth-STEM-charity donation may receive a 2026 coin by U.S. mail or DEF CON pickup. The same page links the official CircuitPython Bradán Lane STUDIO Coin M0 profile as the build specifically for the eChallengeCoin. That profile identifies an ATSAMD21G1A, 4 MB flash, three RGB-NeoPixel groups, three capacitive touch pads, a speaker, and native USB-C. The linked primary sources therefore document a real planned independent DEF CON 34 electronic artifact while also disagreeing about USB connector type and touch-pad count; this record preserves the conflict rather than resolving it. They do not establish final manufactured-unit parity, confirmed donations or delivery, charity/tax treatment, official DEF CON issuance or admission, game-source licensing, or reusable-image rights.
