v1.0 // Go + QUIC + WebSocket

Mt8870 Proteus Lib 35 _verified_ Jun 2026

A lightweight Go binary that moves files and relays multi-user chat over QUIC. Works from the CLI or a browser. No accounts, no cloud — just room codes.

~/airsend 
# start the server (web UI + QUIC relay in one process)
$ airsend -sw 0.0.0.0 3888 0.0.0.0 8443
→ web: http://0.0.0.0:3888  ·  quic: 0.0.0.0:8443

# send a file, get a code
$ airsend -f ./logs.tar.gz

Features

Everything you expect.
None of the bloat.

One binary. Two transports. Zero dependencies at the user’s side — no account, no install step for the receiver if they use the browser.

Many guides and file links are from 2008–2014, referencing older Proteus 7 or 8 versions, and are often tied to unreliable download portals like "cinurl.com" or broken community shares.

Here are the most common paths:

Open the "Pick Devices" window (hotkey 'P') and search for MT8870 to add it to your schematic. 4. Simulation Environment Setup

Rapidly fluctuating analog frequencies from the input generator overwhelm the solver. mt8870 proteus lib 35

DTMF decoding requires real-time frequency analysis. If your PC is slow, the simulation might stutter. Lower the "Simulation Time Step" in settings if necessary.

: Use the "Generator Mode" in Proteus to inject audio signals or pre-recorded DTMF tones to verify the decoder's response.

Copy the downloaded MT8870.lib and MT8870.idx files into the LIBRARY folder. I cannot directly send you the binary library file (

One-shot file pickup

Files are deleted from the server after the first download. Code-based lookup (wave21, dock42). No lingering blobs.

Multi-user chat rooms

Broadcast rooms by code. CLI TUI or browser — identical semantics.

Rate limited by scope

Token bucket per IP × scope: upload, paste, download, ws. Proxy aware.

Direct P2P mode

Bypass the relay entirely with -d / -ds. Pure peer-to-peer.

Self-signed TLS

Protocol "airsend" over generated certs. Intentional.

How it works

Three commands. One code.
