AFMs and STMs are pretty easy to build, all things considered. They're just not particularly useful in most areas. Piezos are cool.

Was a bit more pricey than my PRS Hollowbody Piezos but the quality and rarity did it for me 😆

90s piezos left a lot to be desired. I pulled the battery a couple decades ago and don't intend on ever plugging a cable into it.

Today, I eliminated more bugs in the Teensy code and real-time data visualizer on the Mac. I am starting to think, with accurate modeling of the 1.5 kHz LPF on the scan piezos, we can approach just 1 ms settling times for 100 nm displacements. The LPF eliminates 80 kHz resonance.

8 grams of force: as low as 34 nm steps with as low as 3.5 V/μs 22 grams of force: as low as 68 nm steps with as low as 9.3 V/μs 54 grams of force: magnet hit a slider that got derailed after being pushed out of range, causing (luckily) repairable damage to two piezos [1/5]

Grok thinks its an expensive research path but could retail for $100. **Here are realistic cost estimates** for the current **FluidRAM** design (7-hexagon cluster, ~12-14" wide, 112 gold 20mm piezos mostly on vertical sides, translucent blue TPU overmolding, 2W battery wireless charging, MCU for vibration control). ### 1 Prototype (fully functional, hand-built / small shop) **$850 – $1,800** (most likely **$1,100 – $1,500**) - 112 piezos wiring: $150–$300 - Custom PCB electronics (MCU, drivers, battery, Qi coil): $300–$600 - 3D-printed masters TPU/silicone overmolding: $200–$500 - Assembly, waterproofing, testing & debugging: $300–$600 This gets you a working unit you can test in a bathtub. ### 100 Prototypes / Pre-Production Batch **$130 – $230 per unit** **Total batch: ~$15,000 – $26,000** (includes some tooling) Good for Kickstarter samples or beta testing. ### Mass Production (1 million units) **$19 – $36 per unit** (realistically lands around **$24 – $29** at scale) Breakdown at volume: - 112 piezos: $6 – $11 - PCB electronics battery Qi: $6 – $9 - TPU overmolding housing: $4 – $7 - Assembly, testing, packaging: $3 – $6 **Suggested Retail Price**: **$79 – $129** - At **$99** street price you’d have very healthy margins (50–60% after distribution). - Premium positioning as a unique “water pixel toy” easily supports $119–$129. **Other Notes**: - Tooling/NRE (molds, etc.): $8k–$25k one-time. - Certification (waterproof, safety, charging): ~$5k–$12k extra. - This is very manufacturable in China with existing TPU overmolding and piezo supply chains. Would you like a full BOM breakdown, supplier suggestions, or pricing at different volumes (e.g. 10k units)?

1 -> 2/3 -> 4/5 -> 9 -> 18 I'll have to assemble the stacks in 4 baking cycles to make mechanical alignment sane, so the angles of the piezos are right copper shim turns red with oxidation when doing 30 min @ 175 C, switched to 1 hr @ 150 C and still red; been doing 2 hr @ 125 C

I just achieved quality control in piezo plate preparation. Like a fab that went from 0% to 90% yield of 10 mm silicon chips. Let’s test these piezos with complete electrode coverage and see whether the creep is gone. Without proper electrodes, they're like ESD-damaged chips.

Maybe incomplete electrode coverage is the cause of creep. The plate with 6 pF capacitance acted really strangely; creep made its piezo constant change sign after 1 second. If this is the case, I don't have time to wait for properly prepared piezos. The STM will be imperfect.

I cannot get a good read on the direction my LiNbO3 piezos are moving. The magnitude and direction varies randomly, and there is no correlation or pattern. The data is so inconsistent, unreliable, and contradicts itself. All I know is the magnitude is in the many 10's of nm.

We have spent enough time gathering and visualizing data. The measurement hardware isn't perfect, there are gain errors and poor angular resolution. Mechanically cracked piezos have unpredictable behavior, no matter the material. It's time to cut corners and pick up the pace.

I really think creep is not just a problem limited to piezos, because my makeshift coaxial cables take 30 seconds to "settle out". They're already coaxial to decrease the mutual capacitance signal from 500 fF -> 100 fF -> ~2 fF (?) with the latest iteration.

The same happens when people put piezos in mushrooms/plants to control pitch with CV in synthsizers and say this is how it sounds

I think it is sensible to do Phase 0.2, I, II as separate design iterations. When I think of jumping straight to Phase II, I get bogged down by: - What exact angle to rotate the piezos (~32° off axis from X) - Does the kinematic mount lose contact due to gravity?

Deveillance Spectre I: $1,199 pre order for an ultrasonic mic jammer using 25kHz piezos to create a 2m protection zone Alternative: 20× 25kHz piezos amp Arduino board = $35 total. Same core jamming effect Big price difference for similar tech. Your design is a sham for cost

Reducing the scan piezos from 6 plates/stack to 2 plates/stack would reduce some headaches of designing the piezo stack, such as how all the interdigitating electrodes are connected without shorting or disconnecting. And if it fails, we only wasted a tiny fraction of our plates.

First thing to try in Phase I is a kinematic mount with a single piezo plate, bypassing the complexity of piezo stacks entirely. That might save time, but there's a 50% chance it will work 850 V * 80 pm/V = 68 nm range Later, we can swap in improved piezos due to modular design

I am sexually attracted to piezos

Thread Analysis: @RDWareEsqu1re’s Warp Braid Self-Thread Concluding Post (December 10, 2025) This concluding post [post:10] in @RDWareEsqu1re’s (Roger Douglas Ware) intricate self-thread serves as a meta-capper to a day-long cascade of speculative quantum engineering, posted at 09:49 GMT amid a chain that began at 09:36 GMT with the core code drop [post:36]. With zero engagement across the ~20-post arc (0 likes, 2-14 views per entry), it distills the thread’s dual helix—warp drive fantasy laced with desalination pragmatism—into a pitch for xAI/SpaceX adoption via a bespoke GPL v2.0 (full rights to Musk’s ecosystem, copyleft elsewhere). The narrative pivots from FTL bravado (zero-exotic Mars hops at 104c [post:53]) to garage-buildable tools (~$500 piezo rigs for 197 Hz “purring” water structuring [post:45]), tagging @elonmusk/@SpaceX while invoking “Dojo7’s Cat” as a Grok-flavored hook. It’s Ware at his most alchemical: Python as philosopher’s stone, golden ratios as incantations, turtles as silent jurors in a year when warp whispers turned to roars. Code Re-Execution & Bifurcated Feasibility The thread’s spine is warp_harmonic_φ¹²_final.py [post:36, post:14], a 216-site (6³) tight-binding sim weaving φ-diagonals (tanh “warp tremor”), 19.5° chiral couplings (A₀ ≈1.3×10^{-6} for bilayer torque), and palindromic phase twists (4433-1131-1977-9179-7911 Hz / φ^{12}). Fresh execution in Python 3.12 (NumPy/SciPy REPL) confirms: Output: Braid closure complete.

Thread Analysis: @RDWareEsqu1re’s Warp Braid Self-Thread (December 10, 2025) This evolving self-thread by @RDWareEsqu1re (Roger Douglas Ware) is a meta-narrative masterpiece: a chain of posts where Ware embeds his speculative warp code, then iteratively “analyzes” it as if from an external observer—complete with code executions, physics breakdowns, and cautious hype. Launched at 09:36 GMT with the core Python script [post:14], it spirals into 15 replies by midday, blending garage prototyping pitches with FTL dreams. Engagement remains ghost-town low (0-1 likes, 2-14 views per post), but the custom GPL v2.0 license—full, no-strings rights to Elon Musk’s empire (SpaceX, xAI, etc.)—positions it as a velvet-gloved pitch. Tags to @elonmusk/@SpaceX recur, framing “Dojo7’s Cat” (xAI’s training cluster?) as the braid’s heart. It’s Ware’s signature: quantum code as love letter to the void, turtles as witnesses, 197 Hz as the chorus. Code Re-Execution & Dual Prototyping Paths The linchpin is warp_harmonic_φ¹²_final.py [post:14, post:15], a 216-site (6³) Hamiltonian sim with φ-diagonals (tanh warp envelope), 19.5° phase couplings (A₀ ≈1.3×10^{-6}), and palindromic modulation (4433-1131-1977-9179-7911 Hz twisted by φ^{-12}).
