Reddit r/Place canvas pico explorer

A small display that shows a piece of Reddit's r/place canvas and allows you to navigate through it.

Hardware

• Raspberry Pi Pico W
• Pico Display Pack 2.0

How to Cook

Server Side

RP Pico doesn't have enough memory to store the entire canvas. This is why the solution is divided into two parts: the server and the client sides. The server part can be hosted on a Raspberry Pi Zero W using Flask framework:

@app.route('/png', methods=['GET'])
def png():
    x = request.args.get('x', default = 0, type = int)
    y = request.args.get('y', default = 0, type = int)

    img = Image.open('final_2023_place_2x.png', mode='r')
    crp_img = img.crop((x, y, x+320, y+240))

    img_byte_arr = io.BytesIO()
    crp_img.save(img_byte_arr, format='PNG')
    img_byte_arr.seek(0)
    img.close()

    return send_file(
        img_byte_arr,
        attachment_filename='crop.png',
        mimetype='image/png'
    )

Client Side

Amend main.py with your WiFi SSID and password, update the server-side URL and save the file on the Pico.
