EBB is an e-paper bulletin board that syncs over [Scuttlebutt](https://scuttlebutt.nz) (SSB). This program is in alpha so proceed at your own risk :)
|
||||
EBB is an e-paper bulletin board that syncs over [Scuttlebutt](https://scuttlebutt.nz) (SSB). EBB is a [Slow Web](https://www.are.na/morgan-sutherland/slow-web) device. As such it is not intended to be *fast*. Thus users must exercise great patience while operating EBB.
|
||||
|
||||
## Usage
|
||||
|
||||
EBB is a [Slow Web](https://www.are.na/morgan-sutherland/slow-web) device. As such it is not intended to be *fast*. Thus users must exercise great patience while operating EBB.
|
||||
Check out the [operators manual (pdf)](http://teafry.me/ebb/operatorsmanual.pdf)
|
||||
|
||||
After you plug in the device, while the program is loading, the LED is purple, indicating you should wait before interacting with the device. Every couple hours the EBB db is synchronized with SSB and during this time the LED shines white (also wait to interact).
|
||||
|
||||
The device will automatically rotate through images in the database after a set period of time.
|
||||
|
||||
There are 5 buttons on the left side, they are numbered 1-5 from top to bottom:
|
||||
|
||||
**button 1:** takes a photo. The LED will go green while the photo is being taken. The photo will be taken when the red light on the camera itself goes out. A soon-to-be-written feature will allow the user to decide whether they want to keep the photo just taken and whether to store it locally or to post it to SSB.
|
||||
|
||||
**button 2:** advance to the next photo. LED will turn blue while this action is busy.
|
||||
|
||||
**button 3:** currently this button goes to the previous photo in the database (LED will turn blue while this action is busy) but soon the plan is for it to provide a menu with the options:
|
||||
* power down
|
||||
* add friend (via QR)
|
||||
* show my QR (take pic/read the QR, txt to friend)
|
||||
|
||||
**button 4:** delete current photo. LED will go red and an alert with instructions is presented to the user on the e-paper screen. Press button 4 again to confirm delete or press any other button to cancel. The actual BMP wont be deleted, only the entry in the database (and of course it can't be deleted from SSB, so).
|
||||
|
||||
**button 5:** display the weather (currently doesn't work; a planned feature :)

## Building one
|
||||
|
||||
There are *a lot* of steps here, this is not for the faint of heart. But if you're handy on the commandline it shouldn't be too bad. I intend to streamline setup greatly.

||||

1. download [raspbian lite](https://www.raspberrypi.org/downloads/raspbian/) (or whatever basic raspbian image)
|
||||
2. [write the image to your SD card](https://www.raspberrypi.org/documentation/installation/installing-images/)
|
||||
3. follow [these instructions](https://desertbot.io/blog/ssh-into-pi-zero-over-usb) to get into it over usb. AND OR, put in wifi credentials onto the card. [This page](https://www.raspberrypi.org/documentation/configuration/wireless/wireless-cli.md) says how to do it.
|
||||
3. [Put in wifi credentials into the WPA_supplicant.conf file](https://raspberrypi.stackexchange.com/questions/67649/raspberry-pi-zero-w-headless-using-wpa-supplicant-conf-not-working).
|
||||
4. [enable SSH on the device](https://www.raspberrypi.org/documentation/remote-access/ssh/)
|
||||
4. put the card in the pi and boot it up
|
||||
5. ssh-in (or connect to monitor if you didn't do step 3, connect to monitor/keyboard...)
|
||||
6. use `sudo raspi-config`[(howto)](https://www.raspberrypi.org/documentation/configuration/raspi-config.md) to change timezone, set a new hostname, enable ssh, change user password, enable SPI (for e-paper screen), enable I2C (for button shim), enable camera.
|
||||
6. use `sudo raspi-config` [(howto)](https://www.raspberrypi.org/documentation/configuration/raspi-config.md) to adjust:
|
||||

- set a new hostname
|
||||
- enable ssh (if you haven't already)
|
||||
- change user password
|
||||
- enable SPI (for e-paper screen)
|
||||
- enable I2C (for button shim)
|
||||
- enable camera.
|

#### setup SSB
|
||||
I can't remember how I got ssb-server to work, `sudo npm install -g ssb-server` throws `illegal instruction`. Something to do with a woknky version of Node. So my **extremely** hacky workaround is to unzip `ssb-server.zip` from the install directory into `/usr/local/lib/node_modules/`. This is v bad and needs to be fixed asap. [SSB-server](https://github.com/ssbc/ssb-server) is made available via the MIT licese.
