FlokWave

Turn any group of smartphones into a perfectly synchronized wireless speaker system — in under 30 seconds, with no internet, no accounts, and no hardware beyond the phones already in the room.

FlokWave solves the clock synchronization problem that makes multi-device audio fail. Each phone has an independent clock that drifts without correction, producing audible echoes. FlokWave implements an NTP-style ping-pong calibration protocol that converges clock offset to sub-20ms accuracy in ~3 seconds using a two-phase adaptive weighted average — and maintains that accuracy indefinitely with outlier rejection.

System audio — any app
Captures audio from Spotify, YouTube, podcasts, games — anything playing on the host device.
Two-phase clock sync
10-ping burst at α=0.5 for fast convergence, then α=0.1 steady-state with 50ms outlier rejection.
QR code session join
Host generates a QR code. Clients scan and connect in one tap — no manual IP entry, no pairing.
Live sync diagnostics
60-second sparkline offset chart per client with max/average offset and green/red status indicators.
Jitter buffer with PLC
SplayTreeMap-indexed buffer with 30ms gap tolerance and Opus Packet Loss Concealment on dropped frames.
Fully offline
LAN-only, no cloud relay, no accounts. Works on shared WiFi or the host's personal hotspot.

NetPulse is an open-source network intelligence and behavior monitoring platform built for the organizations that enterprise tools have always ignored. Schools, startups, co-working spaces, and clinics all have real network security needs — but tools like PRTG and Darktrace cost $50,000/year and require a team of engineers. NetPulse deploys in minutes on a Raspberry Pi or any Linux machine and provides device discovery, DNS activity logging, behavioral anomaly detection, and a real-time web dashboard.

Device Discovery
Passive ARP monitoring and active scans. Live inventory with hostname, IP, MAC, vendor via OUI lookup, and trust status.
DNS Activity Logging
Passive sniffing of UDP port 53 traffic. Every domain lookup recorded with requesting device, domain, timestamp, and type.
Real-time Dashboard
Web-based admin UI with live WebSocket updates. Active device count, domain queries, traffic timelines, and alerts.
Device Profile Pages
Dedicated profile per device showing identity card, full DNS history with time filters, and activity timeline chart.
Behavior Analysis Engine
Rolling statistical baselines per device. Detects anomalies — sudden DNS spikes, access to malicious domains, new unknown devices.
Smart Alert System
Contextual alerts for unknown devices, high DNS rate, suspicious domain access, and potential data exfiltration patterns.
Multi-site Edge Agents
Deploy lightweight agents on Raspberry Pi or x86 at multiple locations. All agents report to a central dashboard.
Network Security Reports
Downloadable PDF/CSV reports: weekly summaries, per-device activity logs, alert history, and domain access statistics.
