Lomography - Konstruktor DIY Kit

Product Information

The reason that I built a curved film plane camera is because the pinhole I bought produced a 150 degree image. This is huge, and as a result, if the film at the center was at the required 65mm focal length, the sides would be off by tens of millimeters. The image would only be in focus for the very middle of the image, and this is unacceptable. If you're somebody who likes to take film photographs, you know the satisfaction you get from a film photo that you just don't feel when you use digital. Just imagine seeing the first photo you get out of a camera you designed and built yourself! It is a fantastic feeling that you absolutely must experience! Make the pinhole in the bottom end of the container. You can either poke a hole directly through the bottom of your container using a pin, or you can cut a larger hole about 1/2-inch by 1/2-inch out of the bottom of your container and poke a pin through a separate piece of paper or thin metal. The second method is usually preferred as it allows you to make a more perfect circle and start over if you mess up the first time. You can usually do an initial focus with the camera assembled on a desk. Point it out a window during the hours of darkness and focus on a building at least 50m away.

Of course, [Stan]’s camera doesn’t look much like and off-the-shelf DSLR. There’s a reason for this; the sensor in the camera has a rolling shutter, much like the last few iPhones instead of a focal plane shutter. Not a bad piece of work, we only wish there were more build pics. Obviously, no other camera or meter is going to allow f221 as an option, so we need to make some calculations to find out how to do an equivalent exposure time from something that we can measure. Receiver– You’ll have one signal in wire to connect to either an UART RX port or a dedicated SBUS port etc. You may also have a telemetry wire which will connect to a different UART TX!OSD– If you have an OSD you will have connectors for video in, video out and then grounds for both signals. It is important that you use these grounds for both your camera and VTX if you want clean video.

Note that over short lengths of up to about 5m you can also use plain PoE connectors. These simply feed 12V from a power supply into the ethernet and extract it at the other end. Over short distances this will supply the camera with adequate power without the need for 48V injectors. There's lots to do. Youll need to mount your pinhole on the "front" of your box, drill holes for the film spool knobs, mount your film plane, drill a window for reading the film numbers. There's lots to do that is very design-specific and unique so I'll leave the problem solving to you, but take a look at what I did for some ideas if you need them. When attaching them make sure that you put them on the right way! This diagram from hobbyrc shows it nicely, make sure to put your props on nice and tight.

Once the camera is installed, connect up the PoE adapter, attach a long network cable and run it to wherever you are going to keep the Raspberry Pi. Remember to ask permission before drilling holes in the walls...:) My problem is to make a very light thermal camera with FLIR Lepton or Boson cameras that are smallest, lightest, and least power-consuming, to be placed on top of a harmless drone. I know I need a video streaming output from the camera, an interface to bring video signal to a 5.8Ghz Chinese (Ali express, Banggod, Gearbest…) transmitter and need to receive the signal of the thermic camera to receiver video that is connected to my tablet or smartphone via OTG. For each of 480 successive frames, we can capture one line to the Arduino at high speed before sending it to the PC at 1Mbps. Such an approach would see the OV7670 working at full speed but would take a long time (well over a minute). Building your own DSLR HD camera is probably not something you're going to be able to do unless you're an electrical engineer. These devices are very complex and require a number of specialized circuit boards and other materials. However, creating a simple homemade camera isn't that difficult. Pinhole cameras can be built with a few basic items. The only difficult part is developing the film, but even that isn't too hard. First of all, congratulations for the excellent article, is helping me a lot to understand all the science behind the camera.
