This is one of the strangest animals I’ve ever made.
I think it’s not very well known, but without a doubt, in my opinion, it’s one of the most beautiful animals that can exist.
It was difficult to articulate, so there weren’t many parts I could make articulated besides the tentacles.
You will need glue for the shell, and everything else is a press fit, so you’ll need to use a bit of muscle.
I hope you like it, and thank you for downloading!

A photograph of a red, white, and blue trucker hat. Printed on the white front panel in black script is the text "Non-consensual facial Scanning @ Wegmans," with "Wegmans" stylized to mimic the supermarket's logo.

This could be my fault…in a good way! Wegmans updated their Statement on Facial Recognition Technology page. There’s no “updated / changelog” note, or a date. No announcement or press release about the press release, just a little edit today. It’s changed since our last bit of coverage where we went line by line to translate how bad it was (and still is).

We compared the old version against the new. Here are the current and previous screenshots and what has changed.

Wegmans removed “communities that exhibit an elevated risk.” This was the most revealing line in the original…Wegmans deciding which neighborhoods deserve face scanning based on some internal risk score nobody outside the building ever reviewed. Now it just says “a small fraction of our stores.” Somebody in legal read our translation and realized how bad it sounded.

They also added an unprompted denial. New sentence: “The data is not, and will not, be used for any other purpose.” When a company volunteers a promise you didn’t request, someone internally asked a question.

The word “biometric” disappeared. Old version: “other biometric data such as retinal scans.” New version: “information like retinal scans.” One word gone, but multiple states have biometric privacy laws. Hey, even if you stop calling your data biometric, it’s still what you called it the first time. No take-backsies!

Expanded the third-party language. Old version said they don’t share data with “any third party.” New version adds “nor do any third parties have access to the data.” Sharing and access are different legal concepts.

Small stuff: “Images and video” became “facial recognition data.” Tightening language before someone FOIAs them, probably.

Wegmans isn’t explaining the rewrite. So far they have removed the neighborhood profiling language, dropped a word that triggers state privacy statutes, and added promises nobody asked for. But they’re still doing the same stuff. This isn’t the transparency that people who shop there want. More like they got caught saying stuff they should not have, and they are trying to revise it the wrong way.

The right thing to do is to post the actual policy, the data retention policy, ways to opt out, and also a way to inquire if you are on their secret list. Not the PR version… the real one, the one asset protection actually follows.

Wegmans should give a number of days on retention, not “aligns with industry standards,” which means nothing and they know it. Disclose which exact stores have the cameras. Publish how people get added to the watchlist, how long they stay on it, what triggers removal, and what happens when there’s a false match – because there will be false matches (there always are) and right now there’s no process, no remedy, and no one gets told.

Even the US government no-fly list has a redress process. Wegmans’ secret face database does not. Wegmans should let an independent auditor look at accuracy rates, false positives, and demographic bias instead of hiding behind unnamed “training and safety measures” that nobody can verify. Disclose any law enforcement data sharing agreements, not just “scan data,” all of it. And stop doing stealth edits on the statement page. Have a dated change-log, with versions, notify people see when it changes. (We’re already getting tons of Terms of Service changes in our inbox)

A grocery store that maintains a secret biometric watchlist with no oversight, no appeal, and no transparency is running a private surveillance system in a place people need to go every week to feed their families. “Just shop somewhere else” isn’t an answer, because soon every chain will be look to doing the same thing, and they will, unless someone makes it expensive not to.

Wegman’s cameras are still on, biometrics are still collected. This time, they have slightly better words.

NEW PRODUCT – TermDriver 2 by Excamera Labs


TermDriver 2 from excamera is a USB-to-serial interface with a built-in screen to show the data passing by. It supports baud rates from 110 bit/s to 2 Mbit/s, all the while showing critical line status and traffic on its tiny yet full-featured monitor. The terminal emulation supports standard ANSI escape codes, so colors and layout are faithfully reproduced on the TermDriver display.

You can use TermDriver 2 just like any other fully featured USB serial adapter. It supports high speeds and includes a 32 KB input buffer, capable of supplying up to 350 mA at 3.3 V. TermDriver 2 can also operate independently of USB, allowing it to be added as a console to embedded systems, such as a Raspberry Pi.

The USB-Serial Adapter That Shows You What’s Happening

Every embedded developer has been there: staring at a blank terminal, wondering if your serial connection is working. Is the device sending data? Are the control lines connected? Is that the right baud rate? Traditional USB-serial adapters leave you guessing, forcing you to juggle multiple applications and debug blind. TermDriver 2 changes everything. It’s the first USB-to-serial adapter with a built-in screen that shows you exactly what’s happening on your connection in real-time. See your serial traffic, monitor line status, and debug connection issues at a glance—all while delivering professional-grade performance up to 2 Mbps. Stop switching between windows. Stop wondering if your connection is working. Start seeing your serial communication.

Visual Debugging: See Your Serial Connection in Action

The built-in IPS display transforms how you work with serial devices. Instead of blind troubleshooting, you get instant visual feedback on everything happening with your connection. Watch serial data stream by in real-time with full ANSI terminal emulation—colors, cursor positioning, and formatting are faithfully reproduced on the compact screen. Monitor the control signals with live status indicators. If something goes wrong, you’ll see it immediately. The display isn’t just for monitoring—it’s an active debugging tool. Identify connection issues before they derail your development session. It’s like having a logic analyzer and terminal emulator built into your USB-serial adapter.

Professional Performance: Built for Real Work

TermDriver 2 doesn’t compromise performance for convenience. The dual-core RP2040 architecture dedicates one ARM Cortex-M0+ core entirely to USB-UART communication while the second core handles display rendering. This ensures maximum throughput and zero data loss even at high speeds.

Support for baud rates from 1200 to 2 Mbps handles everything from vintage equipment to modern high-speed protocols. The 32 KB hardware input buffer captures every byte during traffic bursts, so you’ll never lose critical data. And with 350 mA of clean 3.3V power available, you can drive sensors, microcontrollers, and peripherals directly without external power supplies. The firmware is carefully optimized for performance and reliability. Precise timing and robust error handling ensure your serial communication works exactly as expected, whether you’re flashing firmware, debugging embedded systems, or interfacing with industrial equipment.

Standalone Operation: More Than Just USB-Serial

TermDriver 2 operates independently of USB connections, transforming it from a simple adapter into a versatile embedded systems tool. Connect it directly to a Raspberry Pi, Arduino, or any other system with a UART, and you have an instant console monitor that doesn’t require a connected computer. This standalone capability makes TermDriver 2 perfect for field debugging, headless system monitoring, and situations where bringing a laptop isn’t practical. The device can log serial traffic, display status information, and provide visual feedback even when no computer is present. Whether you’re troubleshooting a remote installation, monitoring sensor data, or debugging a headless embedded system, TermDriver 2 gives you eyes on your serial communication wherever you need them.

Celebrate Black History Month through art, talks, and more at the Metropolitan museum of Art! Here are some details about the ongoing exhibit Before Yesterday We Could Fly: An Afrofuturist Period Room

Seneca Village—a vibrant nineteenth-century community of predominantly Black landowners and tenants—flourished in an area just west of The Met, in what is now Central Park. By the 1850s, the village comprised some fifty homes, three churches, multiple cemeteries, a school, and many gardens. It represented both an escape from the crowded and dangerous confines of lower Manhattan and a site of opportunity, ownership, freedom, and prosperity. In 1857, to make way for the park, the city used eminent domain to seize Seneca Village land, displacing its residents and leaving only the barest traces of the community behind.

This project has roots in the homes of Seneca Village, of which only a fragmented history remains. Like other period rooms throughout the Museum, this installation is a fabrication of a domestic space that assembles furnishings to create an illusion of authenticity. Unlike these other spaces, this room rejects the notion of one historical period and embraces the African and African diasporic belief that the past, present, and future are interconnected and that informed speculation may uncover many possibilities. Powered by Afrofuturism—a transdisciplinary creative mode that centers Black imagination, excellence, and self-determination—this construction is only one proposition for what might have been, had Seneca Village been allowed to thrive into the present and beyond.
