BSidesTLV 2026 Alice Controller Badge documented pre-event

challenge access mechanism

The README says the published stages are sealed under a 32-byte stage key that is written into the badge's vault at the booth. The site asks for the badge over WebHID, or reads the key that the badge spells on its stick axes when SELECT and Y are held, and pauses when the badge is unplugged. A stock DualShock 4 or a badge on stock firmware is sent to the flash page.

BSidesTLV 2026 badge page

Official Down the Rabbit Hole badge page describing the badge as part controller, part game platform, and part challenge, with a hidden challenge beyond the game. It says the badge was listed for purchase for one week only, with a last purchase date of Sunday, October 11, 2026, because of manufacturing timeline constraints, and it sells a separate soldering-workshop kit. An Internet Archive capture of October 5, 2026 already shows the purchase window.

BADGE | BSides TLV

Primary official source showing that the 2026 badge is sold separately rather than stated as included with registration: purchase listing open for one week, closing Sunday, October 11, 2026, because of manufacturing timeline constraints. It also describes the controller, game, and hidden-challenge framing and the soldering workshop with a purchasable solder kit. It gives no price, quantity, or count of badges sold. The live page was checked on October 24, 2026; the Internet Archive holds captures from September 30 and October 5, 2026.

BSidesTLV 2026 Badge README (pre-event rewrite)

README rewritten on November 9, 2026 around the finished badge. It says the challenge is live on GitHub Pages; that the published stages are sealed under a 32-byte stage key written into the badge's vault at the booth, so the site gates play on the badge over WebHID or the Gamepad API; that glitch.html trains the badge as a fault-injection and side-channel tool in five rooms; that the badge is a grip a phone sits in over USB-C and reads as a wired DualShock 4; and that a level maker with an MCP bridge for coding assistants accepts community rooms by pull request. It is pre-event documentation, not a record of on-site use.

BSidesTLV Badge — Soldering Guide

Organizer repository created November 10, 2026, the day before the event, holding a single index.html guide and parts photos; the guide is live on GitHub Pages (HTTP 200 on November 12). It titles the kit BSidesTLV 2026 Tiny Badge, a round light-up badge where a 555 timer (U1) clocks a CD4017 counter (U2) that chases the LEDs, a trimmer (RV1) sets the speed, and a CR2032 cell powers it, with R1 10 kOhm and R2-R5 470 Ohm per-LED resistors, parts sourced from LCSC, and the Alice and rabbit artwork on the back. The repository has no license, so its photos are not copied.
