Unit Ideas

Wi‑Fi relay

  • Based on esp8266 in a standard mechanical and DIN‑rail form factor; ideally also reflash Sonoff relays for the same purpose.

Trigger on esp8266

  • State switcher, the simplest input device into an MQTT broker — literally a button.

Pipeline trigger on esp8266

  • Sequential presses activate a new stage or stages of some tasks each time; must have an RGB LED to indicate the currently running task. Linear and cyclic modes.

Action handler

  • Scheduling actions with the ability to cancel.
  • The main action is applied after a specified delay.
  • While this delay is running, the action can be canceled.

Wi‑Fi module for Flipper based on esp32

  • Control anything that can be controlled via MQTT and receive data from the outside, with the ability to receive notifications, etc.
  • Connect to Wi‑Fi only to send messages; this will save the Flipper's battery a lot.

Hotkey desktop application in Go

  • Tracking hotkeys, like the next item, but without low‑level interception.

Hotkey sniffer on esp8266

  • With switching between several type-c devices: 1 input from the keyboard and 3 or 4 outputs. Intercepts the stream of symbols from the keyboard and sends it to the input of some device or a series of devices; also allows switching between devices via hotkeys — a simple KVM switch. Essentially allows you to control some infrastructure without a computer.

esp32 with camera

  • For very cheap monitoring of anything — snapshots on demand.

esp8266 microclimate station on bme280 and mh-z19b

  • A very compact device for measuring humidity, temperature, pressure and CO2. For outdoor use, you can simply remove the CO2 sensor.

Reflashable Sonoff ready‑made devices

  • Can replace many of the things listed here; factory housing is a huge bonus.

Segment picker in Go

  • An application that creates a picker around the cursor, where you select a segment by moving the mouse in that direction.

Fan with adjustable thrust vector

  • A regular 120 mm cooler, but so that its direction can be adjusted using some motors.

Mini scales

  • Load cell.
  • Two plates should come out of the device between which you can measure force.
