I got a new phone a week or two after Pebble servers were finally switched off and then discovered that the apps and watchfaces I wrote a couple of years ago just disappeared when I paired my Pebble Time with the new phone. I couldn't find a way of getting them off the old phone and onto the new. Luckily, I'd published a couple of them (Conway and Bouncy) on the app store, and discovered rebble had mirrored it and lots of other useful resources. I also managed to track down a couple of them (built binaries) on an old laptop I'd used at the time and installed them manually (by copying the .pbw file to the phone).

But mostly I just had the original source code, last built against a now-obsolete SDK. So I decided to see if I could get them working again in the post-pebble/rebble era, and eventually, with some help from the resurrected rebble resources, and their discord channel, I got a the old apps and watchfaces up and running, see below.

I've open-sourced a selection of my apps/watchfaces from my private svn repo. Feel free to (re)use the code as you wish (it's a MIT licence). NB they've only been tested with the Pebble Time (aka basalt) hardware.

Other than the time and date, this has 2 bouncing rings, the blue/grey one represents the bluetooth connection, the green/yellow/red one the battery charge. One of the rings is affected by gravity.

Just the time, plus a 12x14 wrap-around implementation of Conway's Game of Life (B36/S23 variant) in background. Starts with a randomly placed "glider". A new glider is added if you shake the watch, or if all cells die out. Cells are colour-coded according to their longevity. The time digits go pink if the bluetooth connection is lost.

Displays the GBP price of Bitcoin and a graph of the recent (~1.5days) history.

Does what it says on the tin. Bearing is red during calibration (which can take a while, moving around helps)

Attempt at a bouncy ball game. Only the white ball is affected by gravity. Collisions with the red ball reduce its size.

Attempt at phone proximity detection by monitoring the bluetooth connection. Green if connected, red if not. Was intended for locating a lost phone but the (re)connection is too slow to be practical.

It's a bit confusing but there's two SDKs to install:

• First follow the installation instructions from the original pebble site that rebble salvaged

• Then do

pebble sdk install https://github.com/aveao/PebbleArchive/raw/master/SDKCores/sdk-core-4.3.tar.bz2

NB the pebble executable is not automatically on your PATH, even in the virtualenv. It's at ./pebble-sdk-4.5-linux64/bin/ if you'd rather not mess with your .bashrc.

First clone the repo

git clone https://github.com/virgesmith/rebble

Then choose one of the apps, e.g.

$ cd Conway
$ ./prebuild.sh

the prebuild script symlinks to the common directory, there are lots of source files shared across the apps. Would be nice to integrate this into wscript if possible.

Now build

pebble build

Turn on developer mode in the Pebble phone app, note the IP address, then

pebble install --phone <ip-addr>
