01 — Grinder / DIY Body-Modification Scene (2026 landscape)

One doc in the biohacking scene-map project (see ../CLAUDE.md). Oriented toward two end-goals: (1) substrate-independence / mind-uploading ("Friendship is Optimal"); (2) "biopunk 2037" bioengineered-organs future. The chip/RFID/NFC/magnet implant scene has its own deep folder at /workspace/health/chip-implants/ — it is summarized + cross-linked below, not re-researched. Effort here goes to the rest of the grinder scene.

Researched 2026-05-31 via web search. Claims tagged demonstrated (happened, observable) vs. aspirational (claimed/planned). Confidence: C1 primary · C2 credible secondary · C3 inferred · C4 anecdotal · C5 unknown. Source URL on every factual claim; unsourced claims marked.

TL;DR

• The grinder scene is small, aging, and ideologically fracturing, not growing. The core DIY-implant community is maybe low-hundreds of active people worldwide; the annual flagship meetup Grindfest (Tehachapi, CA) drew ~60 people in 2024–2025 (Baffler).
• The commercial chip-implant layer is the only part that scaled — Dangerous Things / VivoKey (Amal Graafstra) is a real business; everything more radical (sensory implants, DIY gene therapy) stays artisanal, one-off, and mostly aspirational. See chip folder: _summary.md.
• Grindhouse Wetware (Tim Cannon; Circadia, Northstar) — the scene's most ambitious hardware org — is effectively defunct (ceased ~2017). Its flagship implants were demonstrated as one-offs, never productized.
• Sensory augmentation is split between artists (Neil Harbisson's antenna, Moon Ribas) doing genuine long-term demonstrated self-experiments, and consumer haptics (David Eagleman's Neosensory) that work but aren't implants. North Sense / Cyborg Nest is discontinued.
• DIY CRISPR / DIY-bio = Josiah/Josie Zayner & The ODIN (still selling kits) plus community labs (Genspace, BioCurious, Counter Culture Labs, all still open in 2025). Self-injection gene-therapy stunts produced no demonstrated efficacy and at least one adjacent death (Aaron Traywick, 2018, not the injection itself).
• Relevance to the two end-goals is mostly cultural, not technical: grinders supply the morphological-freedom ideology and a willingness to be early adopters, but their actual hardware is decades short of an uploading bridge or engineered organs.

1. The chip / RFID / NFC / magnet implant scene (summary + cross-link)

This is covered in depth at /workspace/health/chip-implants/ — read _summary.md for the full evidence map. One-paragraph version for this project:

In 2026 the consumer chip-implant market is small and concentrated around two US sister companies, Dangerous Things and VivoKey Technologies (both founded/run by Amal Graafstra, Seattle), plus an EU-only payment vendor (Walletmor) and regional resellers (KSEC UK, Upgraded Humans / I Am Robot DE) (chip _summary.md; Graafstra's roles confirmed on LinkedIn and Crunchbase). Capability splits sharply by price: a $25–$150 passive NFC/RFID chip is an access token / business-card / low-security ID; a $349–$449 VivoKey Apex Flex is a genuine CC EAL 6+ JavaCard secure element (FIDO2 passkey, OpenPGP, TOTP, crypto-wallet, Tesla key) but not a payment card. Magnets (finger-pad or injectable xG3) give a real demonstrated haptic "magnetic sense." Safety evidence for bioglass implants is reassuring where measured (FDA-cleared bioglass since 1994; 3 T MRI heating ~1.9 °C) but no aggregate human infection rate has ever been published; only one peer-reviewed human infection case report exists (Schiffmann 2020, S. aureus, middle finger). Magnets must be removed before MRI. Regulation is a deliberate grey zone; 14 US states ban employer-mandated chipping.

Demonstrated vs. aspirational: passive NFC/RFID, magnets, LEDs, FIDO2-on-Apex = demonstrated, shippable today. Active/battery-powered subdermals, GPS, glucose, payments-on-Apex = not available in any consumer implant (chip _summary.md, finding #5).

Connection to end-goals: these are peripheral I/O and identity tokens, not a path to uploading or organ engineering. The magnet "sixth sense" is the closest thing the scene has to demonstrated sensory augmentation via implant.

2. Key orgs & people (the grinder hardware scene)

Grindhouse Wetware — Tim Cannon (Pittsburgh) — largely defunct

• Who: Founded 2012 by Tim Cannon & Shawn Sarver; the scene's most ambitious DIY-implant hardware collective (Wikipedia: Grindhouse Wetware; Grindhouse — Vice "The DIY Cyborg").
• What they actually did (demonstrated, but one-offs):
• Circadia — deck-of-cards-sized subdermal biometric sensor; sent temperature via Bluetooth, inductive charging, subdermal LEDs. Implanted in Tim Cannon's forearm Oct 22, 2013 by body-mod artist Steve Haworth in Germany. Removed after a few months following panic attacks (Wikipedia: Tim Cannon; HandWiki). Demonstrated as a proof-of-concept; never productized.
• Northstar V1 — coin-sized PCB with 5 red LEDs in a star pattern + Hall-effect sensor, CR2325 battery; group implantations Nov 2015 at the Düsseldorf "Cyborg Fair." Never retailed at scale (chip _summary.md table). Aspirational V2 (gesture recognition, magnetic-north sensing) was announced but not delivered as a product.
• Bottlenose — wearable using implanted/haptic magnets to feed sensor data (e.g., distance, EM) into the nervous system via the magnetic sense (Wikipedia). Prototype-stage.
• Status: The company ceased operations ~2017; in 2017 it spun a project off for animal applications due to regulatory challenges; Cannon stayed involved until at least 2022 (handwiki / search synthesis). No evidence of new product releases since. Treat Grindhouse as a historical actor, not a live vendor. (C2)
• Skeptic's take: Grindhouse is the clearest case study of the grinder ceiling — talented hobbyists demonstrated genuinely novel subdermal electronics on themselves, but could never cross the chasm to a safe, regulated, manufacturable product. The one battery-powered consumer subdermal anyone in the scene built (Northstar V1) never shipped at scale and the company is gone.

Dangerous Things / VivoKey — Amal Graafstra — the commercial success

Covered in the chip folder. The point for this doc: Graafstra is the only person in the grinder scene who built a durable business (Dangerous Things 2013; VivoKey 2018) selling implant hardware to a mainstream-ish audience (Crunchbase). He is also CTO of Walletmor. This is the commercialization pole of the scene.

Lepht Anonym — the underground icon

• Who: Pseudonymous British biohacker, the scene's folk hero; wrote the foundational "Cybernetics for the Masses" talk (29C3) about cheap, painful, DIY home implants (magnets, RFID) (Privacy PC transcript).
• What they did (demonstrated): Self-implanted dozens of devices (reports of 50+ magnets/chips) using vegetable peelers and vodka, sometimes with nerve damage — the literal embodiment of the DIY-grinder ethos (Interesting Engineering). (C4 — self-reported / journalistic.)
• Status 2026: Still active and present at Grindfest 2024, where they called it "biohacker Disneyland" (ABC News, May 2024). Identity still concealed; current residence unknown (C5).
• Skeptic's take: Lepht's value is ideological/iconic, not technical — proof that the scene runs on radical bodily autonomy and pain tolerance, not on demonstrable capability gains.

Science for the Masses — Gabriel Licina — the night-vision stunt

• Who: Now-defunct California DIY-bio research group. Best-known member Gabriel Licina.
• What they did (demonstrated, briefly): In 2015 dripped the photosensitizer chlorin e6 (Ce6) into Licina's eyes attempting enhanced night/low-light vision. Reported ~4 hours of apparent improved low-light detection; no permanent blindness, but no controlled validation and no plan to repeat (Boca Raton Observer feature). (C4 — self-experiment, not peer-reviewed.)
• Status: Group defunct; Licina now reportedly runs Scihouse, a makerspace/biohacking lab in Jacksonville, FL (same source). He is a recurring figure at Grindfest and helped set up Cassox's lab (Baffler).
• Skeptic's take: The Ce6 stunt is the archetypal grinder result — a viral, dramatic, aspirational "new sense" with a four-hour anecdote and no reproducible data behind it.

Grindfest & the meetup layer — Jeffrey "Cassox" Tibbetts

• Grindfest is the annual IRL grinder/biohacker meetup in Tehachapi, California, running >10 years; "a mad scientist conference meets a family reunion," ~60 attendees (Baffler; Grindfest 2025 page, Augmentation Limitless). Co-organized by Jeffrey Tibbetts ("Cassox"), a former nurse who runs a body-mod/implant practice (ABC News).
• What gets shown (demonstrated at meetups): microchip door locks, finger magnets for sensing live wires, NFC chips linked to websites, LED implants, prosthetic eyes with embedded lights, livestock temperature-tracking chips repurposed for humans; glucose monitoring "in development" (ABC News). Other recurring attendee: Anastasia Synn, a magician with a Guinness record ~52 implants (ABC News).
• 2026 ideological note: Cassox has moved part of his work to Próspera, Honduras (the Thiel/Altman-linked special economic zone), where his lab Augmentation Limitless has started injecting NFC-activated under-skin crypto wallets — a flashpoint in the community over VC capture and regulatory-arbitrage medical tourism (Baffler). (C2)

Cyborg Nest / North Sense — discontinued

• Who/what: Liviu Babitz & Scott Cohen launched Cyborg Nest (2016); first product North Sense, a chest-mounted module that vibrates when the wearer faces magnetic north (an "exo-sense," pierced-anchor mount, not deep implant) (Surface Magazine; Oddity Central).
• Status: Discontinued — sold out and not reproduced; commercial product effectively dead by ~2018 (biohack.me forum threads). (C2)
• Skeptic's take: North Sense actually worked as a north-facing buzzer, but the company couldn't sustain it — same pattern as Grindhouse and Cyborg Nest's later projects: working demo, no durable business.

3. Sensory augmentation / substitution & the "I want new senses" subculture

This is the most philosophically central grinder sub-current (new qualia, morphological freedom) and the one with the cleanest demonstrated results — but the demonstrated wins are mostly non-implant haptics or single-artist long-run experiments, not scalable implants.

Neil Harbisson & the Cyborg Foundation — demonstrated, long-term

• Who: Catalan-British-Irish artist, born with achromatopsia (total color blindness). Co-founded the Cyborg Foundation (2010) with Moon Ribas; also the Transpecies Society (Wikipedia: Neil Harbisson).
• What he did (demonstrated, 20+ years): Has worn an "eyeborg" antenna implanted into his skull since 2004 that converts color wavelengths — including IR and UV — into audible tones via bone conduction; the antenna can also receive external image/color/internet signals (Wikipedia; Cyborg Arts). Widely described as the first person whose government (UK passport office) accepted a cybernetic device as part of his body — "first legally recognized cyborg" (a media framing, not a formal legal status) (Wikipedia; Electronic Design). A documentary, Cyborg, was released 2024 (Cyborg documentary site).
• Skeptic's take: This is a real 20-year sensory-substitution experiment (n=1), but it's an artist's practice, not a reproducible product or a measured perceptual study. "Legally recognized cyborg" is a passport-photo anecdote inflated by press, not a legal precedent.

Moon Ribas — demonstrated, artistic

• Dancer/choreographer; co-founder of Cyborg Foundation. Has implants (arm/foot) that vibrate in response to real-time seismic data, letting her "feel earthquakes" worldwide; performs choreography driven by the feed; next step is a live lunar seismic feed (Design Indaba interview). Demonstrated as performance art; n=1. (C2)

North Sense, magnet "sixth sense," IR/EM sensing

• Magnet sixth sense = the most demonstrated implant-based new sense in the scene: a finger magnet lets you feel AC fields, transformers, live wires, and (with a wearable like Bottlenose) arbitrary sensor data routed to the magnet (Hackaday primer; chip _summary.md). Real but low-bandwidth.
• IR / EM sensing implants: mostly aspirational. The magnet-as-transducer route (external IR sensor → coil → magnet buzz) is demonstrated in principle (Bottlenose), but no shipping consumer IR-sensing implant exists in 2026 (C3, chip _summary.md finding #5).
• Lab-side science (non-grinder, but relevant): flexible magneto-sensitive e-skin prototypes that give a touch-free magnetic perception are advancing in academia (ScienceDaily 2015; News-Medical 2024). Demonstrated in lab, not in humans as a chronic sense.

Firefly / tritium / UV glow "tattoos"

• Firefly Tattoos = subdermal vials of tritium gas (beta decay → phosphor → glow) coated in lead-oxide glass to block radiation; glow for years (tritium half-life ~12 yr) without charging (Cyberise.me Firefly background). Distinct from xGlow (passive phosphor, UV-charged) and from LED implants (xLED, Northstar) (chip _summary.md). Demonstrated as niche body-mod art; "new sense" only in the loosest sense (it's decoration / signaling, not perception). (C2)

David Eagleman / Neosensory — demonstrated, commercial, but NOT an implant

• The "new senses" idea has its most commercially successful, evidence-backed expression outside the grinder scene: neuroscientist David Eagleman's company Neosensory sells the Buzz wristband (haptic sound-to-vibration) and Clarify (speech assist for hearing loss), descended from his "VEST" sensory-substitution research (Eagleman.com; Neosensory science page). Wearable, non-invasive, FDA-adjacent consumer hardware. (C2)
• Why it matters here: It shows the brain genuinely can learn a new sensory channel (the load-bearing premise of the whole "new senses" subculture) — but the working version is a wristband you can take off, not a grinder implant. The grinders' implant route adds risk without (yet) adding capability over Eagleman's wearables.

4. DIY CRISPR / DIY-bio

Josiah / Josie Zayner & The ODIN — the face of DIY genetic engineering

• Who: PhD biophysicist (U. Chicago), ex-NASA; founded The ODIN (Oakland garage) ~2016 to sell consumer gene-engineering kits. Now goes by Josie, has disclosed she is transgender (Wikipedia: Jo Zayner; Technology Networks).
• What she actually did (demonstrated stunts; efficacy NOT demonstrated):
• 2017: Live-injected CRISPR designed to knock out her myostatin gene for muscle growth — first person to publicly attempt self gene-editing with CRISPR (BuzzFeed News). No muscle effect demonstrated; widely read as performance/provocation.
• 2020: With the "Central Dogma Collective," self-tested an open-source DNA-based COVID vaccine, livestreamed, protocols open-sourced (Wikipedia). No efficacy data.
• Sells DIY bacterial CRISPR kits ($120–$169), a "DIY Human CRISPR Guide," and (2018–19) GloFish-style / mutant-frog IGF-1 kits ($299–$499) (Fortune; The ODIN press).
• Regulatory history: Investigated 2019 by the California Dept. of Consumer Affairs for practicing medicine without a license; investigation closed Sept/Oct 2019 with no action (MIT Tech Review; Bloomberg). California also passed (2019) the first US law requiring DIY CRISPR kits to carry a warning that they're not for self-administration (MIT Tech Review).
• Status 2026 (uncertain): The ODIN's own press page is stale (last item 2016) (the-odin.com/press) and Wikipedia's substantive timeline stops at 2020 (page last edited March 2026 but no new activity logged). I could not verify any major new Zayner self-experiment or product after 2020 (C5 — see open questions). The kits still appear to be for sale; Zayner remains a podcast/interview presence (Ketone-IQ / HVMN podcast).
• Skeptic's take: Zayner is a brilliant communicator and the scene's most effective democratizer of access to molecular-bio tools — but her headline self-experiments produced zero demonstrated therapeutic effect, and she herself has at times called the myostatin stunt a mistake. The real, durable contribution is educational (kits, protocols), not medical.

Aaron Traywick / Ascendance Biomedical — the cautionary death

• Who: Self-styled biohacker CEO of Ascendance Biomedical, an explicitly regulation-eschewing outfit.
• What happened (demonstrated, dark): Oct 2017 he dropped his pants on stage at a Texas biohacking conference and injected himself with an untested herpes gene therapy; Zayner publicly criticized him for making unverified medical claims (MIT Tech Review; ScienceAlert). April 29, 2018: Traywick, 28, was found dead in a sensory-deprivation float tank in Washington DC; police reported no foul play (ScienceAlert; Wikipedia: Aaron Traywick). The death was not attributed to the gene therapy, but it became the scene's defining tragedy and a marker of how far the self-injection wing strayed from safety. (C2)

Community labs — Genspace, BioCurious, Counter Culture Labs — the responsible wing, still alive

• Genspace (Brooklyn, 2010) — first publicly accessible BSL-1 community bio lab (Wikipedia: DIYbio). Still operating.
• BioCurious (Silicon Valley; moved Sunnyvale → Santa Clara) — volunteer-run nonprofit, bills itself "world's largest community lab"; active in 2025 (biocurious.org).
• Counter Culture Labs (Oakland) — active 2025 programming (mycology, plant bio meetups May 2025) (Meetup); co-runs the Real Vegan Cheese cellular-agriculture project with BioCurious (CCL profile). (C2)
• FBI / DIYbio safety history (demonstrated, positive): The FBI has engaged DIYbio since 2009 (first contact at iGEM); a top NY WMD coordinator attended Genspace's 2010 opening; the Bureau co-ran outreach with AAAS and explicitly treats the amateur-bio community as partners, not a threat (AAAS; FBI-DIYbio 2012 transcript). This is a notable case of pre-emptive self-policing/biosecurity cooperation rather than crackdown. (C2)
• Skeptic's take: Community labs are the healthy, durable part of DIY-bio — accredited safety levels, classes, cellular-agriculture projects — and they are explicitly not the self-injection wing. They've survived where the stunt-driven actors (Ascendance, Grindhouse, Cyborg Nest) collapsed.

5. State of the scene in 2026

Shrinking / fracturing at the radical core; growing only at the commercialized edges.

• Underground DIY core is small and static. Grindfest holds at ~60 attendees; the flagship forum biohack.me is archived, not actively maintained ("we know it's a mess… inherited weird code") (biohack.me; forum archive). Activity has migrated to Discord (a "Grinding" server, transhumanism/grinding servers) and informal channels (biohack.me forum: Transhumanism/Grinding Discord; Disboard biohacking tag). (C2/C4)
• "Biohacking" the market is booming — but that's mostly NOT grinders. Vendor market reports put the broad "biohacking" market at roughly $24.5B (2024) → ~$28.2B (2025) (GMInsights), with the wider vendor cluster spread across ~$20B–$45B for 2025 (e.g. Mordor, Fortune Business Insights, Precedence Research) and aggressive 10-year forecasts up to ~$110B–$217B. That growth is wearables, supplements, longevity, corporate wellness — the Bryan-Johnson / quantified-self end (see 06-mainstream-longevity.md §5, which uses the same vendor-estimate range), not garage implants. (C4 — these are squishy vendor/market-research estimates that disagree by ~2×; treat as directional only. Earlier drafts of this doc cited ~$1.36B→$1.70B, which was an order of magnitude too low and is corrected here.)
• Commercialization vs. underground is the defining 2026 tension. The Baffler argues the scene has drifted from grassroots DIY toward VC-funded longevity and regulatory-arbitrage zones (Cassox's move to Próspera, Honduras, Thiel/Altman-linked), with under-skin crypto-wallet implants as the new frontier — and that "fascistic and individualist sentiments have always lurked beneath" (Baffler). The community itself is split on this. (C2)
• Deaths / injuries / regulatory actions (demonstrated):
• Death: Aaron Traywick, 2018 (float tank; not attributed to his self-injection) (ScienceAlert).
• Injuries: documented implant infection requiring debridement (Schiffmann 2020); magnet pressure-necrosis cases; Lepht Anonym's self-reported nerve damage. No published aggregate rate (chip _summary.md). Doctors at Grindfest flagged infection, inflammation, and imaging incompatibility risks (ABC News).
• Regulatory: Zayner investigation (closed 2019); California DIY-CRISPR warning law (2019); 14 US states ban employer-mandated chipping; no biohacker has faced a major criminal conviction for self-experimentation (chip _summary.md; MIT Tech Review). (C2)
• Where they gather now: Grindfest (annual, Tehachapi); Discord servers; the archived biohack.me; body-mod studios (Cassox / Augmentation Limitless, Russ Foxx, Steve Haworth); Dangerous Things forum (the most active vendor community); Próspera/Honduras as an emerging in-person hub for the regulatory-arbitrage wing. (C2/C4)

Connections to the two end-goals

(1) Substrate-independence / mind-uploading (FiO). The grinder scene contributes ideology and early-adopter willingness, not a technical path. Magnet senses, NFC implants, and sensory-substitution antennas are peripheral I/O — they touch the body's surface, not the connectome. None of it reads, preserves, or emulates neural tissue; the relevant work is BCI (03-bci-neuralink.md) and WBE/preservation (04-wbe-uploading.md). The one genuinely transferable lesson is neuroplasticity for new senses (Harbisson, Eagleman/Neosensory): brains do integrate novel sensory channels — encouraging for the "the brain can run on new substrates of input" intuition, but a long way from running the mind on a new substrate. Grinders are, at most, the cultural farm team for a future BCI-adopter population.

(2) Biopunk 2037 (bioengineered organs / body cultivation). Closer in spirit, still far in capability. DIY-bio (Zayner, community labs) normalizes hands-on genetic engineering and the "edit your own biology" ethos that biopunk-2037 assumes — and cellular-agriculture projects (Real Vegan Cheese) show community labs can do real synthetic biology. But grinders have demonstrated no tissue/organ engineering, no functional gene therapy, no regenerative result. Self-injection stunts produced zero efficacy and one adjacent death. The real biopunk-2037 path runs through funded labs and organ-sac startups (02-bay-bio-startups.md, /workspace/health/organ-sacs/), not the garage. The grinder scene's contribution is the demand side and the morphological-freedom politics (cross-link 05-trans-transhumanism.md / Próspera), plus a pipeline of people willing to be first.

Net: the grinder/DIY-bodymod scene is culturally upstream of both end-goals and technically peripheral to both. It supplies norms (radical bodily autonomy, open-source, self-experimentation) and early adopters, while the load-bearing technology lives in BCI, WBE, and funded synthetic-bio.

What I couldn't verify / open questions

• The ODIN's current (2024–2026) activity is a C5 gap. Its press page stops at 2016 and Wikipedia's timeline stops at 2020. I found no confirmed new Zayner self-experiment or major product post-2020. Failed/weak searches: "Josiah Zayner 2025 new project," "ODIN 2024 2026 gene therapy." Needs a direct check of the-odin.com store + Zayner's current socials.
• Grindhouse Wetware's exact shutdown date is fuzzy — sources say "ceased ~2017," Cannon "involved until ~2022," but Wikipedia still lists the site as active (page edited 2026). Whether any entity still trades under the name is C5.
• Scene size is anecdotal. "~60 at Grindfest," "low hundreds active worldwide," Lepht's "50+ implants," Biohax's "~4,000 Swedes chipped" — all journalistic/self-reported. No census exists. Magnitude is C3/C4.
• Biohacking market figures (~$20–45B for 2025 across vendors; GMInsights ~$28.2B) come from commercial market-research vendors with incentives to inflate and disagree by ~2×; cited as directional only (C4). They also conflate grinders with mainstream wellness. (A prior draft cited ~$1.36B→$1.70B, an order of magnitude too low — corrected.)
• Próspera / Augmentation Limitless details (crypto-wallet implants, who's actually getting them, scale) rest mainly on one Baffler piece; not independently corroborated (C2, single-source).
• North Sense / Cyborg Nest current corporate status (fully dissolved vs. dormant) not confirmed beyond forum reports of discontinuation (C2).
• Firefly/tritium implant legality & real radiation dose — vendor (Cyberise.me) claims lead-oxide shielding makes it "implant safe"; no independent dosimetry found (C4).
• Lepht Anonym's identity, location, and current implant count in 2026 — deliberately concealed; unverifiable (C5).

Sources are linked inline. Primary/credible-secondary used throughout; market-size numbers and scene-size figures flagged as directional. No firsthand testing — compiled review. Not medical advice.
