Lithium Niobate: A New Era for Scanning Probe Technology. What started as an addiction to building atoms, transformed into a search for the most accessible UHV STM. Discovered a promising solution to a problem that has plagued SPM since its inception.

This is just too cool to not share. Theory and simulations being used to optimize hardware in ways not possible before. @elmerfem

Would be nice if I had the time to investigate this, but compromises must be made to get things done. Started a GitHub repo to track the next phase of hardware testing:

The circuitry also looks surprisingly accessible and DIY-able. This paper used a home-built design. The note about using low forces and/or low stiffness has me worried. Poor resonance frequency could preclude pm-stable vibration isolation, but be okay enough for EUV litho.

More optimistic about the speed of coarse nanopositioning, a critical component of Phase IV of my APM Roadmap:

There might be UHV-compatible voice coil designs (note: be super skeptical of any technology being claimed UHV compatible, often it's just regular HV). Okay to sacrifice fast mm-scale Z movements, if the set of differently coated/tilted Si wafers are mutually flat to O(1 μm).

Replacing the coarse XY nanopositioners of an AFM with voice coils + Michelson interferometers, like what ASML uses for EUV machines. O(10 nm) resolution.O(10 mm/s) speed.No confirmation that resonance frequency is ≥1 kHz.

Nanofactory Corp. & CBN Nano Technologies happened over the exact same time period as 2b2t's history. There should be a 3-hour documentary covering the entire disaster after they finally give up on hiding it, and spill the details.

We live in an imperfect world with broken software tools. One could choose to continue just talking, but I’m gonna get something done. Fast low-noise transimpedance amplifier + its power supply system. Designed the correct way, how I like it. Self-imposed deadline in 39 days.

Successful reproduction of the Elmer tutorial for 3D magnetic fields around a wire.

Any you know what, I see genuine academic merit to Eric Drexler's protein engineering. I'm going to foster the exploration of alternative ideas, because we can't afford to leave stones unturned if we take APM seriously. R&R were overly dismissive of him.

Our message is single-crystal clear: we're pursuing APM at our own rapid pace, and no actions by R&R will slow us down. We assert our authority over our actions by not compromising or negotiating on the nano- equivalent of AI safety programs.

I'm not going to be held back by patent trolls enforcing the CBN patents on tripods, especially when they can't yet lead to profitable atomically precise products. Or whatever tricks we've suspected R&R might use over the last 2 years.

The experimental setup for MBE & UHV STM is very complicated, so I won't do it IRL anytime soon. But I will eventually. Keeping this secret only delays progress and reduces the chance that Nanomedicine / cryostasis revival happens in the next decade. We're waiting, Ralph and Rob.

If any such information in fact exists, then keeping it closed source would hamper open-source experts from checking it for security flaws. The most advanced cryptographic protocols are those from open standards, undergoing public peer review.

Ralph and Rob should disclose any experimental data on inverted mode tip registration. With rigorous assurances that they're not hiding Concealed Observables or giving an intentionally incorrect Methods section. This should happen at or before the October 2025 Foresight Workshop.

Let's start actively drafting a plan to make sure the APM Treaty Compliance Inspection Program never happens. Our action will be quick, decisive, and send a clear message. Ralph and Rob have no power over how we proceed, now that we're the ones in charge of our own future.
