One-button time-management with the Raspberry Pi.

Ever get frustrated by time logging? Replace all that time spent navigating crummy UI and doing mental math with a Work Pi on your desk!

It's very easy to use, with only one button

• rotate to scroll through currently-assigned tasks
• click to start time logging
• click to stop time logging

Note that this is a work in progress and currently has no export feature - it is easy to integrate into any time-logging API.

This is also an excellent platform for any project involving a rotary-encoder and a raspberry pi. Use this to build your own weather station or thermostat interface or other such things if you like.

The WorkPi runs a simple pygamescript which interfaces with a rotary encoder + button. Wiring up and installing the button requires drilling a single hole and soldering a few wires.

This device can be built with only a few Adafruit components. To replicate this you'll need the below:

• Raspi TFT Plus (2.8") kit
• Raspi TFT enclosure
• Raspi TFT Faceplate
• Raspberry Pi (2/3/4)
• Rotary encoder (with integrated button)
• Big metal knob

NOTE: if you are Canadian, like me, I recommend Elmwood Electronics when purchasing Adafruit products

The following connections will be made between the rotary encoder and the RasPi-TFT's GPIO header (not the raspberry pi's own physical GPIO pins!).

I recommend soldering these to the PCB so as not to ruin the expansion GPIO header on the RasPiTFT.

** TODO measurements + pictures**

1. Just drill a single hole in the RaspiTFT enclosure on the side which has the microSD slot. Once inserted the encoder will fit nicely above the microUSB connector and below the RaspiTFT PCB.

2. insert the Raspberry pi into the enclosure

3. screw in the rotary encoder

4. insert the raspiTFT and faceplate

   Done!

There isn't a whole lot going on beyond just a simple startup script:

1. Install the RaspiTFT drivers from the link here.
2. Clone this repo into your /home/pi directory (as /home/pi/WorkPi)
3. Make it run on startup by adding sudo python3 /home/pi/WorkPi/run.py to new file/etc/init.d/workpiscript
4. cd to /home/pi/WorkPi and run sudo python3 install -r requirements

I implore anyone intetested in using this as a work logger to help with the following tasks:

• export functionality
• API connection i.e. JIRA
