pages with both words

the words together, as a phrase

    Volumes

    1. Vol 1 The Fully Wireless Gun — A Pack Inside, a Radio Out, Nothing on the Floor What the fully wireless architecture is, what has to cross the air in each direction, what it changes inside the gun and at the PC, which guns already work this way, and where the first trial stands
    2. Vol 2 The Radio Links Compared — ESP-NOW, Bluetooth LE, LLPM and Enhanced ShockBurst What each 2.4 GHz link does with a light gun's reports, with numbers: frame formats, airtime, the connection interval that dominates Bluetooth, the new 375 µs intervals of Bluetooth 6.2, Nordic's proprietary modes, and where each sits in a crowded band
    3. Vol 3 The Hardware Routes — The ESP32 Port, the Nordic Boards, and the Pico W What the ESP32-S3 port's gun and dongle actually do, read from its source; what Nordic nRF52840 and nRF54L15 boards would buy this build and what they would cost in firmware; why the Pico W's radio is not the shortcut it looks like; and the pick
    4. Vol 4 Latency, Lost Packets, a Crowded House, Four Guns and Pairing What each link adds to the gun's latency against the cable, what a lost packet does to aim, buttons and recoil, where 2.4 GHz interference in a house comes from, how four guns share the air, and how each route pairs a gun with its receiver
    5. Vol 5 Power — The Logic Rail, What Each Radio Costs, Sleep and Wake, and Surviving the Kick How the fully wireless gun feeds its logic from the 6S pack, what the ESP32-S3 and Nordic radios each cost in hours of play, why a gun with no cable needs an automatic off, and how to keep the receiver alive and the antenna clear beside a 2.5 A solenoid
    6. Vol 6 The Dongle's Identity, FCC Part 15, the Bench Plan and the Decisions What USB identity a wireless gun's receiver carries and why decision D24 follows it; what the FCC's Part 15 means for a hand-held radio gun built at home and for one sold as a kit; eleven bench tests on the ADP3450; what the trial costs; and the rows proposed for the decision log
