Calibration Hell Pt. 2: My RGB LiDAR Says the Wall Is Bent | Ep.15
The iToF sensor reports a straight wall bowed 12–14 cm. Longer exposures reduce noise, receiver bugs are patched and multiple causes investigated, yet frequencies disagree by 22 cm. A one-wall fitted correction is local only; cyclic error and spill remain hypotheses, while TMF8829 dToF is considered for a wrist sensor.
Can We Bring Up ToF LiDAR + Camera—and Calibrate Them? | Ep.14
An under-$100 RGB + ToF + IMU concept is evaluated with a custom simulator, then an epc660-class engineering sample is brought up beside a Pi camera. A cable causes two hours of brown-outs. Calibration improves 12.7 to 4.56 pixels but misses the <4 px target; a 30-second map motivates a shared clock, IMU and factory calibration.
Tesla Roadster Thrusters: Can We Make a Flying Car Model?
A 52 cm Roadster-inspired CO2-thruster concept moves from CAD to simulation. Ideal hover gives way to gas-flow limits, valve restrictions, cooling and real component mass. Seven-second hover is an ideal simulation result, with no physical gas test performed.
Can GPT-6.1 SOL Hack a $45 Robot's Bluetooth? | Ep. 12
A Pi Zero 2 W takes control of a toy robot over Bluetooth. Twenty-one SDK tests pass without movement; captured app traffic leads to packet timing fixes, a restart and roughly four seconds of neutral initialization. The physical sequence works but mismatched wheels make forward spin; autonomy remains future work.
Can Gemini Shoot? I Gave It a Robot Arm in My Desk Twin | Ep. 11
Gemini gets cameras, LiDAR and code-writing access to a simulated ECO65 basketball setup. After fixing the desk, physics and gripper, the final five-throw test scores four baskets, while Gemini mislabels one made shot. This is a small fixed simulation test.
Can Opus 5.5 Finally Calibrate My iPhone + Ouster OS0?
The live OS0 is brought back online and localized in the earlier room map. Walking through the iPhone view drives three calibration iterations; a convincing wall fit initially hides a wrong camera pose. Actual body point clusters become a rough avatar, with estimated intrinsics and unseen anatomy.
I Moved Robots Into My Office Twin. One Wave Broke the Humanoid.
The office twin receives simulated Go2 and G1 robots. Calibration, movement, scene reconstruction, lighting and grasping failures precede a humanoid fall when the arm is forced overhead. All robot results are simulation.
Opus 5.5 Built My Physical AI Dojo | LiDAR + iPhone → Robot Training
A real Ouster room scan and 13-second phone video become a simulated physical-AI dojo with splats, labelled objects, colliders and movable parts. Alignment and robot training infrastructure remain experimental; physical parameters are estimates.
GPT-6 co-engineers a low-cost quadruped carrying two SO-101 arms. Across 38 recorded simulation runs, 19 fail; slipping blocks, vision, connection loss and tipping shape the design. A deterministic controller executes the demonstrated run.
Can GPT-6 Drive a Real Robot Arm? (LiDAR + 2 Cameras)
The planned RealMan ECO65 setup is explored using manufacturer CAD and robot description: cameras, LiDAR, interfaces and a target-pose control loop. The hardware has not yet arrived; all arm sequences are simulation.
I Rebuilt a Room from ONE Phone Video — No LiDAR Input | Ep. 5
A 48.6-second phone video produces a room reconstruction without LiDAR input: 187/195 selected images align, 51,475 sparse points and 400,000 Gaussians. Appearance works, while metric scale and unseen surfaces remain unverified.
Old Samsung S10 + $2,000 LiDAR: Can This Work? | The Tech Storyteller Ep. 4
Live Ouster data reaches an old Samsung S10 through a Mac bridge. Pose jumps, IMU compatibility and a disappearing Ethernet adapter expose the gap between displaying scans and reliable mapping; phone localization is still future work.
Can GPT-6 Fix LiDAR / Camera Calibration? | The $5 Camera Experiment
A Raspberry Pi camera and Ouster OS0 produce a coloured point-cloud experiment. Checkerboard and manual matching improve selected static boundaries from about 13.5 to 4.2 pixels, but the person ghost remains unresolved.
I Gave an Old Samsung Phone a Virtual Robot Body | Episode 2
An old Samsung S10 maps the office and gets a simulated robot body. Route replay and virtual exploration work; an attempted autonomous pickup remains unfinished.
Mechanical engineering meets general-purpose AI controlling robot arms: a commentary on a source dual-arm pick-and-place demonstration, introducing the question of what actually works.
