A 3D Printable Retro-style Raspberry Pi HQ Camera

Bill of Materials

Raspberry Pi Zero WH + microSD card
Raspberry Pi HQ Camera
16mm 10MP Telephoto Lens
2.2" TFT Display
TP4056 Micro USB Battery Charger
MT3608 DC-DC Step Up Boost Module
2000mAh Li-Pi battery
Power switch
Shutter button
Dupont jumper wires
3D printed case (see STL folder)
Leather patches for couch (optional)

Schematic

Power from converter connects to Pi's 5V (pin 4) and GND (pin 6)
Shutter button connects to GPIO26 (pin 37) and GND (pin 39)

Raspberry Pi pins	TFT display
3v3 (pin 17)	VCC
GND (pin 20)	GND
GPIO8 (pin 24)	CS
GPIO23 (pin 16)	RESET
GPIO24 (pin 18)	DC
GPIO10 (pin 19)	MOSI
GPIO11 (pin 23)	SCK
GPIO18 (pin 12)	LED
GPIO9 (pin 21)	MISO

Assembly

Software

Flash Raspberry Pi OS to micro SD card. Then add following lines into config.txt:

gpu_mem=256
dtoverlay=rpi-display
display_rotate=2

For application, simply execute this script after boot:

from gpiozero import Button
from picamera import PiCamera
import time

button = Button(26)

with PiCamera() as camera:
    camera.resolution = (4056, 3040)
    camera.framerate = 5
    frame = int(time.time())
    camera.start_preview()
    while True:
        button.wait_for_press()
        camera.capture('/home/pi/Pictures/%03d.jpg' % frame)
        frame += 1

USB Connectivity

Hello team, Could you please explain how to connect the USB cable to this cam? Also could you please specify which USB board to be used for assembly?

Please see the attached image.

display problems

I took a 2.2 "TFT display as recommended and connected it, but a problem emerged. Display Link (https://www.amazon.de/gp/product/B01E0MGZU2/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1)

In a blog it was shown how it can be connected to the Raspberry Pi and in the linked Github project this was also discussed again. But I have a problem that wasn't described there. After starting the script, the image can only be seen in the upper right part of the display, greatly reduced. Unfortunately, the autostart script does not work properly either. I have to run the script to add it to the autostart after every reboot. In addition, the displayed image flickers as if the frame rate is incorrect. The Blog(in German)(https://blog.gc2.at/post/spi-tft-lcd-kernel5/) the GitHubProjekt(english)(https://github.com/juj/fbcp-ili9341)

I very much hope that a solution can be found and that everything works out. Many thanks in advance.

TFT Display Driver

I have this display: http://amazon.com/dp/B01CZL6QIQ However, I have difficulties in making it work.

Could you please share which driver you have used? Any link to the steps much appreciated. @penk

Link to display?

Most displays I've found are 2.8"

Also, are some of these parts like the top glued together? The mount looks like it has structure for screws that line up with the main body but, there aren't guide holes.

Touch Screen Funtionality?

I was wondering if the 2.2" tft was supposed to be a touchscreen. If not, would it be possible to add touchscreen capabilities to be able to change camera settings on the go? I understand that this is a DIY camera, more of a "proof-of-concept" than anything else, but I just feel like having the ability to change some of the basic camera settings in the camera would be cool.

Please upload the original 3D-files of the STLs

This would allow easier modification e.g. for a different button or screen.

I think the STEP-format is quite compatible, but this could be a first step to open up further development. I would love to share some of my modifications of existing STL-files, but i am sadly sometimes limited to do just that.
