This is a tool made to transfer and backup photos from a professional camera while in-the-field. Built with a Raspberry Pi 4 (other Pis will work too, it’s all just Python code), using Wi-Fi for file transfers and USB disks for file storage, powered by batteries.
I’ve had some fun with photogrammetry recently and wanted to try out other techniques for 3D scanning. I’ve actually sort of accomplished S.L.A.M. during a hackathon using the PlayStation 4 camera and the Xbox One Kinect already, but I wanted something portable! With the new Raspberry Pi 4 debuting this year, I can finally accomplish this… sort of…
I got my Raspberry Pi. I do not have an ethernet connection or Wifi dongle available, or an extra keyboard. I don’t have any Bluetooth either. I needed a substitute keyboard to use the Raspberry Pi.
For fun, I designed a little USB device, actually it has two USB devices on a small board in the shape of a stick. Two USB capable microcontrollers are on this circuit. One will connect to the Raspberry Pi, and behave like a keyboard and mouse. The other will connect to my laptop. My laptop will run software that captures keystrokes and mouse events. The laptop will tell the microcontroller what to do, so when I press a key on my laptop, the Raspberry Pi thinks the same key is pressed. (and the same with the mouse)
