BPNVG Project spacer mount for Runcam's DVR

thingiverse

Not exactly a Remix but this is based off of the same project found at:https://defcad.com/library/6fc02ef9-5443-4083-805e-cb57ef98223a/I found it through this youtube video:https://youtu.be/MthrbR4_UAk?si=pCuRUQEG1gioYS5qThe Youtube creator posted the STL files here:https://github.com/justcallmekoko/BPNVG/tree/mainLink to my files on Onshape, a free browser based CAD software:https://cad.onshape.com/documents/63ca9e3b950de590c72f7d25/w/e7dd62a3b773ccb7d773ece6/e/15d431633006b98ebc2b5b9cI learned how to use CAD software to be able to make this.I made a single unit of the goggle and wanted to see if it was possible to record the video coming out of the camera, apparently Runcam, the manufacturer of FPV drone cameras makes a DVR for onboard drone NTSC/PAL video recording onto a microSD. It is intended to be connected to a between an FPV camera and a drones flight controller where the drone app can activate recording but it has a very small physical button that also activates the recording for a max of 5 minutes. I made this part to fit the DVR into the BPNVG project where you can press the open physical button to start a recording.https://shop.runcam.com/runcam-mini-fpv-dvr/I designed this spacer to fit into the BPNVG and hold the chip.PLEASE READ BEFORE YOU BUY A DVR: The DVR has a different operating voltage than the rest of the components, the DVR accepts 3.3-5v whereas the camera I used, the Runcam Night Eagle 3 accepts 5-24v, the Adafruit screen claims to accept 6-12V. I never actually hooked up everything and figures out how to power everything, I have to see I can power everything with a 5v power supply which the screen might not accept and might not be what everyone else is using.There are 2 versions of the file, one that includes a cutout of the chip where it would sit so that it fits more evenly and one without. I printed the one with the cutout but it doesn't seem to sit completely flat. Runcam must have changed the components of the chip compared to the the step file copy of the chip I found on the internet. The other version without the cutout should fit the DVR just fine but it will float a bit. I designed this around the hexagon 2m standoff screws that came in the box with the DVR, they are 4mm but I increased the hole size to account for printer inaccuracy, on my print they fit snug. The standoff part of the screws should be the same size as floating middle section with the threaded part going all the way to the end of the spacer. After seating all of the screws you can put the DVR chip in and keep it on with the little include nuts to match the screws. My goggle was made with a Night Eagle 3, because of this it has an adapter and sits a little outside of it requiring my DVR holder to need some clearance under it, I don't know what kind of clearance something like the Night Cat or other FPV cam might have, please make sure there is at most 3.75mm clearance from the base of the front body/ Camera holder and the back end of the camera and make sure there is room for it's wiring. Because of the orientation of the button to the SD card you're going to have to take apart the goggle to get the SD out and get your video off of it. There should be plenty of room for the wiring betI made the main body of the goggle with 4.25 mm heat set screws, the front, camera holding part has 6mm for screws, and my part is 14.75mm so you're going to need 4x25mm 4M screws to hold the body togetherEDIT DEC 14 2023 - while I dont have al the parts together I made a new version that includes fins with a cutout in order to hold an MP1584EN buck converter. Im going to power everything with a 9v battery and step down the voltage with the converter.
