1. 01

   The whole RaidPost

   A solar post wakes on motion, names the animal with an IR camera, scares raiders with lights and a siren, and rings the house.

2. 02Brain

   XIAO ESP32S3 Sense

   The brain: it runs the raidpost-fw program

3. 

   03

   Three PIR sensors

   Wake the post when a warm body crosses the front or sides

   XIAO ESP32S3 Sense · GPIO wake lines · Motion wake signal

4. 

   04

   850 nm IR LEDs

   Light the scene for the camera for 8 seconds at night

   XIAO ESP32S3 Sense · GPIO to LED driver · On/off switching

5. 

   05

   RAK3272S LoRa radio

   Sends the animal call to the house bell, with no gateway

6. 06

   MOSFET driver board

   Switches the 12 V strobe beacon and the siren

   7 key parts, one program, and your phone

The idea

A smart repeller pole in each raid gap fires only when an animal is there and rings a bell in the farmer's house

How the parts connect

RaidPost, 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 RaidPost

for (;;) {
    light_sleep_until(pir_front || pir_left || pir_right);
    ir_leds(true);
    cls = classify_3_frames(camera, 8000);     // int8 model
    ir_leds(false);
    pat = pick_pattern_not_in_last(3);
    beacon_run(pat, cls);                      // MOSFET board, 12 V
    if (siren_allowed(cls))                    // never for people or elephants
        siren_after(random(0, 4000));
    lora_send(msg_10b(cls, conf, pat, batt_mv()));   // UART to RAK3272S
    delay(60000);                              // cooldown

Key specs

Targets for production units; they may change during development.

Pricing

Target pricing: INR 11,999 (about $145) per post, first RaidBell free, no subscription. Estimated BOM about $171 per post at qty 1 and about $75 at qty 1,000, plus about $26 per RaidBell; the target price needs the lower-cost rev B.

Indicative launch pricing in USD, excluding taxes and shipping. Final pricing is confirmed before any balance is charged.

1. 29 Oct 2026, 11:55LatestSmallholders next to forest or scrub in India lose 10-40% of affected crops to wild boar and nilgai, guard their fields all night, and timer solar flashers (about INR 10,000) blink all night until the animals learn them; illegal live-wire fences have killed elephants and led to cases against farmers (RaidPost DESIGN.md market check).

   • Drawn idea plan (idea.json): a 2-acre maize field on the forest edge from above, with the north gap and the east boar run, the elephant trail through the forest, the farmer's house and its track; pins for a RaidPost on each gap's pole, a forest-edge post on the elephant trail and the RaidBell in the house
   • The product picture is now this drawn plan instead of the plain fallback card; drawn from the design notes, not the CAD
   • What the plan keeps from the market work: posts guard gaps and trails, not the whole edge (a post sees about 12 m), elephants get lights and an early warning only, never a siren, and the bell works over its own radio with no network
   • Next: close-out C5 (buyer review prep for sports) from 12:00; then C6 to C8 for home, kids learning and industries

2. 27 Oct 2026, 05:10A mixed farm with an orchard next to its stock paddock pays for a frost alarm, a trough monitor, a crop-raid flasher and a pest-trap camera, each with its own pole, power and app. Commercial versions cost about $389–1,252 for a frost alarm (Onset, fruitweb), A$749–1,290 for a trough monitor (Farmbot) and about $2,700 for a trap camera (iScout, Perennia).

   • Combined into FarmMast (https://iemilabs.com/products/farmmast/); RaidPost itself is unchanged
