Foot pedal for 22 €

[Renate]

I love my foot pedals, have a bunch, but am always on the prowl for more.
I'm not sure how many people here do or want to use foot pedals for books.
I'd guess there are some musicians in here who might want them for sheet music.
Usually foot pedals are grossly overpriced, > $100. This is not:

But how well does it work? I don't know. I'm still deciding whether to order it.
I can guarantee that the glowing company logo on the back would suffer death at my hands very quickly.

Edit: I did order it.

Hey! How did I end up here?

Alright, I received the dingus.
It is as advertised, connects readily, has tons of options how it should send taps.
The foot switches are not clicky. You'll have to decide if you like the feel.
The white stripes on the foot pedals glow green when on.
There is also a logo panel in the back that glows until I defeat it.

The only minus part is that this identifies as a Qwerty keyboard to Android.
That means unless you set an option (if you even have this option) to tell Android, "please show the onscreen keyboard even though I have a Qwerty keyboard attached", you may have to power this off to type on screen.

There are 10 modes. As indicated, some modes stay down when pressed (allowing Linux autorepeat), others fake auto repeat internally (but slowly).

On the whole, worth 22 €. Apparently available since April 2025.

Edit: There are 3 LEDs on the back, two green for illumination, one red for charging. I removed the two green.
This thing has two slabs of steel inside for weight and non-slip.
This is held together with six screws, two under the rear rubber feet.

Edit^2: You'll have to decide for yourself if the "Continuous triggering"is a feature or not.
If your feet are untalented and you normally only want to do one page at a time it might save you from double-flipping.
OTOH, if you're the type that likes to hold down the button for quickly flipping through (or back) multiple pages you may hate it.

For your reference, here is the HID report descriptor for this beast.
You can see that it's a keyboard, digitizer and consumer control.
With "29 65 Usage maximum (Keyboard application)" they have declared themselves a full keyboard.

This is from the Bluetooth HCI snoop in Developer Settings.
You have to enable it, then reboot.
The log is found in /data/misc/bluetooth/logs/btsnoop_hci.log
