Raspberry Pi HQ Cam M43 Adapter

<p>This is a raspberry pi HQ camera m43 adapter. The HQ camera circuit board screws on to the base (the 4 corner holes). You may need to take off the C/CS mount rings and other hardware for it to fit. Next, you screw on the lock ring all the way to the bottom (this has somewhat tight tolerances but it'll loosen up ones you get it on and screw it on and off a few times). Finally, put on the adapter piece and add a lens. The lens adapter and lock ring screw on in opposite directions so that you can lock them together when you've adjusted the adapter distance correctly. - I'll probably make a single threaded version where they move the same direction at some point which will be easier to print.</p> <p>I get somewhere around 10-20 cycles of adding/removing the lens before the plastic wears too much and the lens won't stay tight. I'm working on a version that canibalizes the metal lens mount ring from a broken camera so avoid the wear and make the adapter last longer. This also only really works with manual lenses since there is no way to control the electronics on the powered lenses.</p> <p>To adjust the flange distance to allow the lens to focus correctly:</p> <p>3d printer tolerance and print settings make it hard to print a fixed adapter that properly focuses to infinity. Follow these steps to adjust the flange distance:</p> <ol> <li><p>Screw the lock ring on to the base and go all the way to the bottom. Only screw it on until you feel a slight resistance.</p> </li> <li><p>Screw on the lens mount adapter</p> </li> <li><p>Attach a lens to the adapter.</p> </li> <li><p>Turn on the raspberry pi camera and open something that lets you see the camera output in real-time</p> </li> <li><p>Slowly adjust the lens mount by screwing it more or less until the lens is able to focus properly at both extremes of its focus range</p> </li> <li><p>Carefully back the lock ring up and tighten it until it won't move anymore. The tighter you make it the more locked the lens mount will be so if you think the focus is working great its probably good to tighten and leave as is.</p> </li> </ol> <p>Printing:</p> <p>I printed all parts with PLA+ at .2 layer height. Depending on your printer tolerances you might try a lower layer height for a better fit.</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>Ender 5</p></div> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div> <p><strong>Resolution:</strong></p> <p>.2mm</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>20</p></div> <p><strong>Filament:</strong> Hatchbox PLA+ Black</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>I designed this to print on my Ender 5 with Bondtech BMG/Mosquito hotend. The printer is fairly well tuned and it took a few tries/experimenting to get some good settings. If .2mm layer height doesn't work try lowering it. Getting the rings to screw on might be stiff/tricky initially. The lock ring isn't very tall so its easy to cross-thread it. </p></div> </p></p></p> Category: Camera
