1. 01

   The whole CycleTap

   A puck on each washer or dryer counts cycles from vibration and motor field, and reports through a room gateway to the owner's dashboard.

2. 02Brain

   ESP32-C6-MINI-1 (puck)

   The brain: it runs the cycletap-puck program

3. 

   03

   Vibration sensor

   Feels the drum running and wakes the puck from sleep

   ESP32-C6-MINI-1 (puck) · I²C (SDA, SCL) · 100 Hz vibration samples

4. 04

   Motor field sensor

   Senses the motor's stray field to ignore a neighbour's shaking

   ESP32-C6-MINI-1 (puck) · I²C (shared bus) · 3-axis magnetic field

5. 05

   Two AA cells

   Powers the puck for years through a 3.3 V converter

   ESP32-C6-MINI-1 (puck) · 3.3 V power rail · Battery power

6. 

   06

   Room gateway

   Collects every puck in the room and sends it upstream

   ESP32-C6-MINI-1 (gateway) · BLE 5 coded PHY · Encrypted cycle events

7. 07

   LTE-M modem

   Sends events to the cloud when the room has no Wi-Fi

   ESP32-C6-MINI-1 (gateway) · UART (TX, RX) · MQTT over LTE-M

   All connected

   6 key parts, one program, and your phone

The idea

Stick-on pucks count every washer and dryer cycle in a building's laundry room, independently of the route operator

How the parts connect

CycleTap, wired up

Every part, what links it to the brain, and how the data reaches your phone. A solid line is a cable; a dashed line is a radio link.

The program

What controls CycleTap

for (;;) {
    esp_deep_sleep_start();              // wakes on LIS2DW12 INT1
    while (activity) {
        lis2dw12_read_fifo(&win);        // I2C, 100 Hz samples
        lis2mdl_read(&field);
        feat = extract(&win, &field);    // RMS, Goertzel 2-25 Hz, |B|
        phase = classify(feat);          // 'neighbour' does not count
        state = cycle_update(state, phase);
        if (state_changed(state))
            ble_advert_ccm(puck_id, seq++, state);
        activity = vibration_in_last(120);
    }

1. 28 Oct 2026, 14:55LatestAn apartment owner who shares laundry revenue with a route operator needs their own cycle count to check each statement and to negotiate the seven-year renewal; an 8-machine room grosses about $1,800 a month and a 5-point better split is worth about $7,560 over a term (est.; sources in DESIGN.md).

   • Drawn idea plan (idea.json): a shared laundry room from above with four washers, four dryers, a folding table and the corridor door; pins for the room gateway, pucks on two washers and a dryer, and the free-now QR tag on the door
   • The product picture is now this drawn plan instead of the plain fallback card; drawn from the rev A1 design notes, not the CAD
   • What we kept from the market work: CycleTap sells to the building owner, not to homes or laundromats
   • Next: drawn plans for more catalogue products, then deeper market checks on the flagships

2. 27 Oct 2026, 11:00A shared laundry room has three jobs: the owner wants to know which machines are down and how many cycles really ran, to check coins or the route operator's statement (route systems like LaundryView belong to the operator); residents want to know what is free before carrying a basket downstairs; and a burst washer hose costs about $5,300 a claim after the deductible (figure attributed to IBHS). Our own three products for it cost about $1,277 and $153 a month for an 8-machine room.

   • Combined into LaundryRoom (https://iemilabs.com/products/laundryroom/); CycleTap itself is unchanged
