Safety notice

  1. Itchcraft is not meant for treating insect bites on human skin.

  2. Using a bite healer causes pain, no matter which software you use.

  3. Improper use of bite healers may cause minor burns.

Synopsis

itchcraft COMMAND

Commands

COMMAND is one of the following:

info : Shows a list of USB bite healers that are connected to the host.

start : Activates (i.e. heats up) a connected USB bite healer for : demonstration purposes.

Flags

The info command does not support any flags.

The start command supports the following flags:

-d, --duration=DURATION

The duration of the demonstration.

One of short, medium, or long.

The default is short, the safest setting.

-g, --generation=GENERATION

Whether the demonstration corresponds to treating an adult or a child.

One of the values child or adult.

The default is child, the safer setting of the two.

-s, --skin_sensitivity=SKIN_SENSITIVITY

Whether the tech demo caters to regular or particularly sensitive skin.

One of the values regular or sensitive.

The default is sensitive, the safer setting of the two.

Environment

Itchcraft supports the following environment variable:

ITCHCRAFT_DEBUG : If set to a non-zero value, causes Itchcraft to enable debug-level : logging. : Also decreases some retry counters and prints stack traces for errors : where it normally would not.

Monitoring the bite healer’s state once activated

Monitoring the state by observing the LED color (recommended)

Your bite healer has a built-in LED, whose color tells you when the ceramic end of your bite healer is currently heating up, when it has finished heating up, and when it reverts to its default idle state.

To start the technical demonstration, follow these steps:

  1. Connect the bite healer to the USB port of your smartphone.

  2. Confirm that the built-in LED is pulsating (either red or green.)

  3. Run the itchcraft start command from a shell.

  4. Wait until the built-in LED turns purple. It will also blink rapidly. The bite healer is now heating up.
    This phase should take only a couple of seconds until the bite healer has reached its target temperature.
    If you were using the original vendor-provided app instead of this demonstration, then the heating-up phase would mean that your bite healer is not yet ready for use.
    Do not worry if you notice the CLI exiting back to the shell at this point. Your bite healer will perform the rest of the demonstration on its own.

  5. As soon as the built-in LED turns blue and no longer blinks, the bite healer has reached its target temperature.
    If you were using the original vendor-provided app instead of this demonstration, this phase would mean that your bite healer is ready to use on the affected area of your skin.
    It is recommended that you do not let your bite healer come in contact with human skin while using Itchcraft.

  6. If you were using the original vendor-provided app instead of Itchcraft, you’d be pressing your bite healer against the affected area of your skin as long as its LED shows a blue light.
    Do not let your bite healer touch human skin while using Itchcraft.

  7. Once the LED turns back to a pulsating green, your bite healer has reverted to its idle state.
    If you were using the original vendor-provided app instead of Itchcraft, you’d be removing your bite healer from your skin at this point.
    Your bite healer is now ready for another demonstration.

Monitoring the state if you have color vision deficiencies

If you find yourself unable to discern the different colors on the LED built into your bite healer, follow these steps to achieve the same result:

  1. Connect the bite healer to the USB port of your smartphone.

  2. Confirm that the built-in LED is pulsating.

  3. Run the itchcraft start command from a shell.

  4. Wait until the built-in LED starts blinking rapidly. The bite healer is now heating up.
    This phase should take only a couple of seconds until the bite healer has reached its target temperature.
    If you were using the original vendor-provided app instead of this demonstration, then the heating-up phase would mean that your bite healer is not yet ready for use.
    Do not worry if you notice the CLI exiting back to the shell at this point. Your bite healer will perform the rest of the demonstration on its own.

  5. As soon as the built-in LED stays lit and no longer blinks, the bite healer has reached its target temperature.
    If you were using the original vendor-provided app instead of this demonstration, this phase would mean that your bite healer is ready to use on the affected area of your skin.
    It is recommended that you do not let your bite healer come in contact with human skin while using Itchcraft.

  6. If you were using the original vendor-provided app instead of Itchcraft, you’d be pressing your bite healer against the affected area of your skin as long as its LED shows a non-blinking, non-pulsating light.
    Do not let your bite healer touch human skin while using Itchcraft.

  7. Once the LED starts pulsating and no longer stays lit, your bite healer has reverted to its idle state.
    If you were using the original vendor-provided app instead of Itchcraft, you’d be removing your bite healer from your skin at this point.
    Your bite healer is now ready for another demonstration.
