Presenter
OffTurn the FlashKa into a Bluetooth keyboard that changes your slides. The laser stays the pointer.

- Previous slide: Page Up
- › hold
- Start the show: F5
- ‹ hold
- End the show: Esc
- ● click
- Black screen on / off: B
- ● hold
- Laser on while held (the S2 switch must be on ARM)
This app disconnects when you start: the light becomes a keyboard, and a Bluetooth light can only talk to one device at a time. To come back, hold ‹ and › together for 2 seconds (or wait for the idle time below), then tap Reconnect.
Save to flashlight stores these settings together with your profile, so they are kept after the battery was removed.
The light remembers up to four computers or phones. Forgetting them makes it ask for a new pairing. (On the light: hold ‹ and › for 10 seconds; the ring blinks white three times.)
How to pair a computer or phone
Start presenter mode first (the ring breathes cyan). No code is asked: pairing is automatic after you choose the device. Pair once; afterwards it reconnects by itself whenever you start presenter mode.
Windows 10 / 11
- Settings → Bluetooth & devices → Add device → Bluetooth.
- Choose FlashKa-XXXX (the letters are on the light's name in this app).
- Wait for "Your device is ready to go".
macOS
- Apple menu → System Settings → Bluetooth.
- Click Connect next to FlashKa-XXXX.
Android
- Settings → Connected devices → Pair new device.
- Tap FlashKa-XXXX and confirm.
iPhone and iPad
- Settings → Bluetooth.
- Tap FlashKa-XXXX under Other Devices.
Linux and ChromeOS
- Open the Bluetooth settings (or
bluetoothctl), scan, choose FlashKa-XXXX, then Pair and Connect.
Not found? Check that the ring is breathing cyan, that the light is not already connected to another computer, and remove an old "FlashKa" entry from the computer's Bluetooth list.
Settings

Demo tools
These act like things you would do to a real flashlight. They only exist in demo mode.
Light
OffProfile
A profile decides how bright each level is and how hard the battery and the LED are pushed.
Lumens: light out of the front of the FlashKa v0.7, estimated from the LED data (85 °C inside the LED) and the 87 % optic - not measured.
The flashlight only remembers the profile and brightness level you picked after you save them.
Edit the Custom profile
Apply switches the flashlight to your Custom profile right away. Save to flashlight also stores it, so it is still there after the battery was removed or the light was off for a long time.
