Raspberry Pi Digital Clock

My old clock broke, and when I looked online there were no good digital clocks. I decided to make one with a raspberry pi 3b+, a screen, and a simple circuit.
Supplies
Raspberry pi 3b+ $30
3.5 inch touchscreen for raspberry pi (HDMI) $20
SD card $1
Powerboost 1000 basic $10
3.7v battery for powerboost $8
switch $.75
SD Setup

Flash you SD card with raspbian. Connect your raspberry pi to the screen using gpio pins. Connect the raspberry pi to a HDMI Monitor and boot it up.
Software

You need a clock software for it, I found the best to be GNOME clocks. To install open terminal and type
sudo apt install gnome-clocks
Once that is done go into accessories on the raspberry pi menu bar. You should see a button labeled clocks. Click it and GNOME clocks will run. Set which state you live in and it will tell the time. Open up accessories and you can move the clock button to the center of the screen so you do not have to get to it, you can just click it.
Soldering

Connect the battery to the powerboost by the connecter. Solder a wire from ground to ground on the raspberry pi to the powerboost. Solder a wire from 5v on the raspberry pi to the powerboost. Solder a wire from the positive on the switch to the EN on the powerboost. Solder a wire from the negative on the switch to the ground that already has a wire in it on the powerboost.
Thanks!

I glued the parts, but you can design the case. Thanks!
