Rundown of the Dangerous Things chip catalog

Super short and sweet rundown of popular Dangerous Things implants. Trying to keep this dense, this isn't a full tech guide.

This is a highlight, some niche implants are omitted.

X-Series are easy to install, many piercers will agree to do it:

- xNT: Basic NFC tag. ($25)
- xEM: Clones LF RFID keys. ($25)
- NExT: Combines xNT + xEM. ($89)
- xLED: Just an LED, lights up near a reader. ($59)
- NExT V2: NExT with an LED. ($129)
- xMagic: Clones LF RFID and Mifare Magic 1K keys. ($149)
- xGlow: Glows in the dark under your skin (no electronics). ($119)

Flex implants have better range and often more features. They are harder to install, so it will be more expensive and difficult to find someone doing it:
- flexNT: Basic NFC tag (xNT) with more range. ($149)
- flexUG4: Clones many many kinds of NFC cards, but not RFID. ($349)
- dUG4T: Combines flexUG4 and xEM with better range. ($429)
- Apex: Passkeys, 2FA, PGP, and cryptocurrency. ($349-449)
- Apex Ring Conversion: Apex with contactless Visa/MasterCard payments. ($549-649)
- flexSecure: Run Java code. Similar capabilities as an Apex but you manage the system yourself. You may need to use the command line instead of an app and you can brick it if you're not careful. ($349-449)
- dNExT: NExT in a massive form factor with lots of LEDs for absolute lunatics who want insane range and crazy lighting. ($500)

The variants for the Apex and the flexSecure are as follows:
- Narrow. Easier install using a 5mm needle, but still harder than an X-series. Might be easier to find someone willing to do it.
- Spectrum. About 1.5× the range and an LED that cycles through the RGB spectrum.
- Module. About 2.5× the range and no LED. Very easy to scan, highly recommended for payments.

The flexUG4 can also be installed with a 5mm needle. The other flex implants above must be installed with a scalpel, which is as tricky as chip implants get.

I can install any of those implants if you need and I've done it many times! But otherwise have a look at the list of Dangerous Things partners, many do all the implants as well. dangerousthings.com/partners/

"I want an implant for [...]" recommendations

I want a simple tag to get started
- xNT is a cheap and simple one
- NExT V2 has all kinds of features in one
- NExT if you don't care about the LED
- flexNT for better range compared to the xNT

I want to copy keys
- xEM for LF RFID
- xMagic for Mifare Classic 1K
- flexUG4 for all kinds of NFC tags
- dUG4T for all kinds of NFC/LF RFID tags and range

I want the most useful implant possible
- Apex Ring Conversion, you'll literally use it almost every day for payments and logging into things
- Apex, if you can't or don't want to use payments
- flexSecure, if the managed firmware of the Apex irks you

I want lights under my skin
- xLED for just the light
- xGlow for UV-charged glow
- NExTv2 if you want some NFC/LF RFID features as well
- Apex/Apex Ring Conversion/flexSecure in the "Spectrum" format (as explained at the bottom of the previous post)
- Blinken Log, not mentioned in the previous post but it's got 5 LEDs in one that light up with LF RFID
- dNExT if you're insane

Things *commercially-available* implants can't do (yet)

Location tracking

Continuous tracking would probably require implanting a battery which is dangerous. But if you're really inclined, you could encapsulate an Airtag I guess? But you'll have to have it pulled when the battery runs out. Also I don't know how much signal you get inside the skin.

Continuous health monitoring

For similar reasons, would require being continuously powered on.

Store significant amounts of data

Best right now is the flexSecure 452, which has 228kb without applets.

The Bodybytes may get us there but I am not sure how much the project is evolving after the incident. See www.protopoint.dev/bodybytes and forum.dangerousthings.com/t/bodybytes-implant/12270?u=iro_miya

Run custom compiled software

The flexSecure runs Java code, but there's no ready-made implant where you can just, like, flash Rust or something. Let alone run Linux.

Again both things the Bodybytes could do if it that project gets off the ground. You could also implant a microcontroller yourself of course like what they did with the pegleg pegleg.org, but there's nothing ready-made like that.

Programmable LEDs

No one has commercialised an implant with programmable LED patterns. It's totally possible, so there's a free business idea for you.

The LED on the flexSecure/Apex Spectrum is not programmable, it continuously cycles through the RGB spectrum.

Purple LEDs

A Vivokey engineer told me that's surprisingly challenging? Apparently purple LEDs drain more power, but I guess a larger implant should be able to harvest enough energy for it. Another free business idea? Rest assured I am regularly bothering them about it as well

bodybytes, re: Things implants can't do (yet)

@iro_miya So the bodybytes is a Linux SoC. We're decent on the software side and the tooling is all set up on Cory's machine but he has to sink a lot of time into hardware bringup which is (a) very expensive (b) a total pain in the ass. So it's taking its sweet time with it, which is fine. This is literally one step before encapsulation, which is why the whole schism hurts this much.

And now for the original correction that sniped me here: bodybytes runs a whole Linux, it can host a fediverse instance. "Just" implanting a microcontroller, with a rust HAL, like ESP32 is something that is a lot simpler. This is because there are less ICs involved in that and no BGA hell. Compare the EMMC flash (128gb user-writeable) on the bodybytes www.kingston.com/en/embedded/emmc-embedded-flash vs an entire ESP32 www.mouser.com/en/ProductDetail/Espressif-Systems/ESP32-S3?qs=Rp5uXu7WBW/NWuUy%2BBihNw== (admittedly not the full-size version this one has a different featureset, but still great).

It's a very optimistic project
