JITTER OS v3.0 (Tactical CM5 Distribution)
Build Status: Hardened | Target Hardware: uConsole + RPi CM5 | Theme: Crimson-Grid
JITTER OS v3.0 is a lean, aggressive, and power-aware build specifically engineered for the uConsole + Raspberry Pi CM5. It moves past the “stock experience” to provide a hardened environment for terminal power users, wardrivers, and field technicians.
THE POWER ENGINE: “Safe-Landing” Logic
The 3.30V Floor: Specifically tuned for the CM5. Triggers a sync and halt at 3.30V to prevent SD corruption during high-drain operations.
Emergency Sitrep: If voltage drops below 3.40V, the HUD shifts to “LOW ALTITUDE” mode, warning the pilot to find a charger.
The Logic: Tapping the I2C Bus
The AXP20x chip sits between your batteries and the CM5. It acts like a high-precision digital scale for electricity. It measures the “Current” (Amperage) by calculating the voltage drop across a tiny internal resistor.
In Jitter OS, the script looks at this specific system file:
/sys/class/power_supply/axp20x-battery/current_now
The Math inside the Script
When you run pwr or pwm, the script performs this operation:
Read the Raw Data: The system returns a value in microamperes (e.g., 350000).
Convert to Milliamps (mA): To make it human-readable for the HUD, the script divides that number by 1,000.
Calculation: $350,000 / 1,000 = 350\text{mA}$
Display: The HUD shows you exactly how much “pressure” the CM5 and your external radios are putting on the cells.
Why watching Amps matters for Jitter OS
Watching voltage alone is like looking at a fuel gauge while the car is off. Watching Amperage tells you how hard the engine is working right now:
Idle: You’ll see it sit around 300mA - 450mA.
Wifite/Bettercap Scan: When those external radios kick in and the CM5 starts processing packets, you’ll see it spike to 800mA - 1200mA.
The “Sag” Warning: If you see the Amperage spike to 1500mA+ while the Voltage is at 3.40V, the Safe-Park Engine knows a crash is imminent because the high load will cause the voltage to “sag” below the 3.30V floor instantly.
PERFORMANCE & ENDURANCE
I’ve tuned the Pi 5 silicon for the handheld form factor to prevent the “thermal runaway” common in the uConsole chassis:
Thermal Capping: CPU hard-capped at 1.8GHz to eliminate heat-soak and current spikes that trigger early shutdowns.
Deep Idle: Scaling floor set to 500MHz to save power while reading or idling.
SITREP HUD: Integrated pwr and stats commands show real-time Voltage, Amperage (mA), Temperature, and Clock speed.
TACTICAL NETWORK STACK
Jitter OS enforces a “Radio Silence” policy on internal hardware to prioritize high-gain external tools:
Hardware Lockdown: Internal Wi-Fi and BT are disabled at the firmware level (reduces interference and heat).
External Priority: Hard-coded for hci1 and wlan1 dominance.
Pre-Loaded Arsenal: Includes wifite, bettercap, aircrack-ng, btmon, and wavemon.
THE LEAN MANIFEST
Stripped: Removed LibreOffice, Wolfram, Cups, Scratch, and Java bloat.
Optimized: Hardware-accelerated Chromium and VLC with full libavcodec support.
Tactical UI: High-contrast Red Jitter Theme with a guarded, single-load terminal banner.
