Whiteboard HyperCard ~ live collaboration/drawing/chat/whiteboarding

Easiest installation through toltec's opkg

opkg update && opkg install whiteboard-hypercard

Self-hosting whiteboard-server / hosting private rooms

On a machine with IP 1.2.3.4 reachable over the Internet, run:

git clone https://github.com/fenollp/reMarkable-tools.git && cd reMarkable-tools && make debug

Now on your tablet, run the whiteboard Rust application with --host, as in:

export WHITEBOARD_WEBHOST=http://1.2.3.4:10001/screenshare
.../whiteboard --host=http://1.2.3.4:10000

Finally, docker compose should show you something akin to:

koreader

• https://github.com/koreader/koreader/releases/latest
• instructions: https://github.com/koreader/koreader/wiki/Installation-on-Remarkable
• creates metadata files:

find ~ -name '*.sdr'

Tools

• cbr2cbz.sh *.cbr unrars then zips CBRs into CBZs so koreader can open them.
• rsync on the tablet:
  1. wget https://raw.githubusercontent.com/Evidlo/remarkable_entware/master/entware_install.sh && chmod +x entware_install.sh
  2. opkg install rsync
  3. And because ssh remarkable 'echo $PATH' #=> /usr/bin:/bin
  4. ln -s which rsync /usr/bin/

Attention

Updates wipe ~

root partition is small

remarkable: ~/ df -h

HyperCards

Visible rectangular elements that can be drawn on/dragged/zoomed/rotated/connected/duplicated.

• tools / modifiers are square cards snapping to the edges of the screen
  • henceforth mentioned as [ToolX] for tool X
  • using them / modifying them by a press held while using the pencil * similar to Minecraft's mix & match: action through combination
  • a [?] tool always hangs in a corner, pressing = shows description text (like crosswords)
  • modification (reorganization / addition / removal) through drawing and pressing
  • tools icons can be drawn too / loaded from a font / loaded from a builtin set of images
  • pen & fingers are different devices for different purposes
    • => drag/move and pinch/zoom (think Apple trackpad gestures) not a pen thing
• whiteboard card
  • rectangle that can be moved by dragging on the edges
  • zoom/rotation by dragging in the area (not the edges)
    • MIGHT: zooming hard moves to another user's view? --> canvas is a window/camera view that can move in 2+1D
  • some bi-directional communication with a networked service
    • user joins a room and shares their live drawings
    • It is possible to combine a [Selection]-ed group of strokes and [Digitize] to ask service for translation
• [Digitize]
  • connects to a distant machine or achieves its AI inference on-tablet
  • takes a few strokes in and outputs text+area / shape+area
• [Selection]
  • draw approximately on one or more strokes
  • creates a group that can be used with other modifiers
  • press another tool before unpressing this one to pass the group to the other tool
• [Image]
  • add an image to a layer
    • should be able to dim that layer
  • select the tool's image with [Setter] > [Image] --> opens image picker
  • image should be draggable + zoomable (= two-finger gesture on iOS Reddit app's image viewer)
    • should be able to draw on top of said image
