FPV MICRO-CONTROL — PRACTICAL HACKS
---
1. Stick Contact
Don’t press — rest on the stick
Pressure = tremor + muscle overloadFingertip (edge) contact
Control from the tip edge → smaller amplitudeDry fingers
Slipping = loss of micro-control (wipe / chalk if needed)---
2. Micro Movements
Move ≠ hold
Use short impulses, not sustained positions1–2 mm rule
Around center, movements stay within a few millimetersPause between corrections
Lets the system respond, reduces oscillation---
3. Vision & Trajectory
Look at the exit, not the obstacle
Your eyes lead the droneFocus on the path/horizon
Don’t fixate on details → more stable controlPredict 0.5–1 s ahead
Otherwise you’re always late---
4. Control Rhythm
Fly in pulses
Input → pause → input → pauseSync throttle + pitch
Channels shouldn’t fight each other---
5. Throttle
Don’t hold constant throttle
Causes drift and overcorrectionUse micro throttle pulses
Better altitude holdMemorize throttle mid
Your altitude “zero”---
6. Body Tension
Relax shoulders → reduces finger tremor
Breathing: short exhale before a tricky move
Support elbows/palms → added stability
---
7. Tuning for Physiomotor Control
Expo 0.2–0.4 → finer center control
Lower center sensitivity → less twitchiness
Don’t overdo feedforward → avoids nervous feel
---
8. Anti-Tremor
Before flying:
warm up fingers (30–60 s)
a few dry stick movements
If you’re shaky: → fly 2–3 slow circles
→ nervous system stabilizes---
9. Simulator as a Tool
10–15 min daily > 2 hours once a week
train slow flight, not speed
practice clean lines, not tricks
---
10. Core Principle
If you’re correcting often — you’re already late.
Solution: → fewer inputs
→ more prediction
→ consistent rhythm#FPV #FPVDrone #DroneControl #MicroControl #PrecisionFlying #DronePiloting #FPVFreestyle #FPVRacing #StickControl #FineMotorSkills #HandEyeCoordination #Sensorimotor #FlightControl #DroneSkills #FPVTraining #DroneSimulator #ThrottleControl #PIDTuning #RCControl #AerialControl #DroneTech #LowLatency #Feedforward #ExpoSettings #ControlTheory

@valthonis I'd submit that it's technically an old world order. I think the system will probably oscillate between the two forms of order at different rates in different territories, albeit over timescales longer than human lifespan. I believe control systems engineers and physiologists call it "hunting behaviour". The tricky thing is the wars that come as one entity wants to wrest power from another. #systemsArchitecture #cybernetics #controlTheory #rayDalio

🤯 The Braingeneers at UC Santa Cruz have blown our minds again: researchers trained brain organoids — tiny pieces of brain tissue grown in the lab — to solve a goal-directed task.
Associated with the UC Santa Cruz Genomics Institute, the team coached the organoids to solve the cart-pole balancing problem, a classic benchmark in #robotics, #controltheory, and #AI used to test whether a system can process information and adapt in real time. -
definitely in the top 5 papers that stand out as introducing eerily prescient pre 20th century equations!
`Jacopo Francesco Riccati (28 May 1676 – 15 April 1754) was a Venetian mathematician and jurist from Venice, known for his widely influential work on solving differential equations. He is best known for having studied the equation that bears his name. `

We are entering the “always-on personal agent” phase.
Tools like OpenClaw promise a local AI that lives your devices and in your tools.
Persistent. Routed. Autonomous. That sounds powerful. It should also make you uncomfortable.
I’m less worried about “AI taking over.” I’m worried about something more structural: Loss of observable feedback.

Idea for AI builders:
LLMs still behave binary at the edge—fluid → snap.
Proposing a graded “Breathing Sheath” between emergence and safety:
a dynamic modulation layer using fractal timing (micro/meso/macro), intention-awareness, and agitation-damping.
Nuance stays; safety holds.
Could this be a root architecture for smoother, steerable LLMs?#LLM #AISafety #Alignment #AIResearch #ControlTheory #CognitiveArchitecture #AIDev #AIUX #AIFutures #TechFediverse

@j2m @ifixcoinops
Also this is FAR cheaper than spending $1000s on skills-training simulators for endoscopic surgery. As a department, I mean.The trick is managing skill progression. So after a month, the clear glass plate has to go, then after another month we have to start adhering the snacks to the machine, etc, etc...
Obviously the advanced vending machine will be very difficult to steal from, and the surgeons will have to put it through a CT scanner first to understand the internal layout, before attempting surgery upon it.

Nononono that's not how the #immuneSystem works! I think your very rational point regarding "?what must be set to zero for this to make sense to a systems-architect" is a most excellent one. Any degree of immunity in #healthcare workers contributes to transmissible pathogens being, well, less-transmitted. When these folks are spending all their time caring for the sick and infirm, that's a lot of moments of reduced-transmission (into a ripe breeding-ground for the pathogen) that happen as a result. Don't even get me started on what happens when a whole #hospital ward changes status from some sort of "normal" status to some sort of "infectious" status. There are a LOT of things that have to be valued at (or near) zero for this to make sense.Also keep in mind that exposure to the pathogen or the vaccine carries some risk... These folks are willing to take that risk - essentially - for free! What a treat.
But wait there's more! These healthcare workers are governed by a famously unsympathetic regulator, who will have little sympathy should standards have fallen because n of the workers were off sick. Those who do go into work are willing to carry that risk, also for free! And even more, some of them might be feeling a bit rubbish too, making it even less probable they can meet those regulatory standards. And they're willing to carry that risk for free too!
I think there's a heap of stuff being valued at zero here, and this is just that which is apparent in a very superficial rant...

You could think of a tach signal as a pulse density modulation. Each clock period is an implicit sample. If the tach is ticking at 1/200,000 the clock speed, then for 200,000 consecutive clocks, there are 0 samples, then there's a single 1 sample.
So I can run that through a low pass filter and get a very low amplitude speed signal? Are there feasible digital filters that work when the cutoff frequency is orders of magnitude below the sample rate?

I guess I should write an #introduction.
I've been using the internet since 1992 and contributing to #Wikipedia since 2001. I haven't used Twitter since early 2021 because I decided it was unhealthy, and I used Mastodon a fair bit that year, but then lost my account through, apparently, inactivity, which I didn't realize was even a thing.
I guess I should put some kind of tag cloud here of stuff I'm interested in? Maybe #physics, #Linux, #Debian, #manufacturing, #DSP, #Python, #Numpy, #math (more #algebra than #analysis), #raytracing, #commonsbasedpeerproduction, #creativecommons, #piracy, #scihub, #libgen, #emergence, #solarpunk, #history (especially #Hellenistic and #Mohist), #UX, #HCI, #controltheory, #lifesupport, and #infosec.

2025 is looking like a great year for work at the intersection of #categorytheory, #systemstheory, #controltheory, #machinelearning and #probabilitytheory, this thread will be a very biased collection of works (in no specific order) I'm hoping to read as soon as possible!
Starting with:

Do you miss a tool like #Matlab|s #Simulink but #opensource #freesoftware and :python: #python-based?
Well, I hacked something together years ago and called it "pyblocksim".
Today I revived the project and added a first very rough automatic visualization of the code-defined block diagrams.
If you are concerned with #controltheory or #systemstheory this might be useful.
Application here is how to continuously approximate a hysteresis element with a tanh-function. 🤓

Dynamic Programming is one way to arrive at the solution of the Markov Decision Process or MDP used in Reinforcement Learning (RL) problems.
In the third article on the Foundational RL series, I discuss dynamic programming and briefly talk about Approximate Dynamic Programming.

Ahh, roger, thank you! That's a really useful explanation; yes, I see why slapOS in and of itself won't cut the mustard. Gosh, I can see why we need this capability from a strategic/geopolitical point of view. Indeed not just Europe; any competent government should want to make sure feedback-loops were set up so that they did not inadvertently lose "digital sovereignty" in such a manner here illustrated.
