Jim’s Build List

Voice AI on Apple Watch Series 11 + iPhone. Dual-mic noise cancellation. Health portal reading heart rate, barometer, and motion. Proactive check-ins based on what it learns about your patterns. Claude-powered — the memory is the moat.

Phase 1: watch + phone. Phase 2: armband (always-on, no screen). Phase 3: Palm Display — MEMS laser onto your palm, your hand is the screen.

Geopolymer concrete matching ancient megalithic construction. The recipe is computed: calcium-richiteite powder + alkali activator + aggregate. The simulation predicts compression strength, cure time, and magnetic alignment of calcite under applied field.

The test: pour a 6-block matrix. Compare to cut stone under microscope. If the grain structure matches Sacsayhuáman or Giza casing stones, the hypothesis is confirmed.

A physical gate that computes without erasing information — approaching the Landauer limit. The model predicts 408× improvement over conventional gates at the sweet spot (840ps gate time, 7nm parameters). No physical gate has been built at this specification.

The test: build one gate. Measure heat dissipation. Compare to Landauer prediction. If it matches within 10%, the model is validated.

The founding vision of GUMP. Sensors on shoes, hands, and torso — the whole body is the instrument. Currently the phone handles tilt and motion. The full version uses IMUs on 4 limbs + torso for 5-point motion capture → real-time music.

The phone version works now (begump.com/instrument). The full-body version needs wearable hardware.

Electromagnetic device based on Leedskalnin’s PMH (Perpetual Motion Holder). Iron core is the secret — stores magnetic flux indefinitely. The simulation shows pulse generation at 33 Hz with 1.34T alignment field.

10 safety systems designed. Full build spec exists. The magnetic alignment of calcite in geopolymer is the target application.

Compound Parabolic Concentrator geometry that concentrates cold sky view for passive radiative cooling. Not a generator — a cooler. The geometry focuses the 3K cosmic background onto a thermal surface, enabling cooling below ambient without power.

The test: build one CPC from sheet aluminum. Measure surface temperature delta vs ambient at night. If ΔT > 5°C, the geometry works.

Our 60-qubit simulator on Apple Metal handles state vectors and gate operations. The next step: implement surface code error correction to create logical qubits from physical ones. The ECHO engine has the framework. The threshold theorem says ~1000 physical qubits per logical qubit at current error rates.

We can’t build a real quantum computer. But we can simulate the error correction that makes them useful, and publish the results for anyone who can.

Don’t build matrices. Encode problems as bytes. Let hardware resonate. Read the exhaust. The principle works on GPU (459 bytes per protein vs 91,400). A dedicated ASIC or FPGA implementation would run orders of magnitude faster.

The design: a chip where the interconnect topology IS the computation. Data flows through coupling pathways, not arithmetic units. The resonance pattern IS the answer.

Sentinel runs as bash scripts. A dedicated Raspberry Pi running sentinel with immune response, hardened OS, and physical LED indicators would be a $50 security appliance for any home network. Plug it in. It watches.

A watch that disappears when you don't need it and becomes a full-color display when you do. Normal mode: Series 11 on the wrist, face up. Plain watch. To activate: flip it upside down and slide it back up the forearm. The band stretches — a strain sensor reads that as intentional. The accelerometer reads the flip. Both together unlock the mode. A MEMS RGB laser pico projector on the case back deploys and rasters a full-color image onto the palm.

The palm is roughly 8×8cm at projection distance — a usable screen, always the right distance, always the right angle when the hand bends back. IR sensors track finger position against the projection for swipe, tap, and pinch. Exit: slide the watch back down, flip right-side up. It's a watch again.

The two-factor mode switch (flip + stretch) means you can never enter it accidentally. The projection surface is your own body. No screen to break. No glasses. Nothing to carry.
