  • shiny goat
    Photogrammetry test of shellacked wooden goat.
  • Cherub Test
    I have been experimenting with bringing photogrammetry to real time graphics, and the first successful test is this cherub. I have been using photogrammetry techniques in film visual effects for many years, and I have been working to bring that high level of organic detail into real-time and mixed reality. The physical model is a …
  • Controlling the MCP
    The name for the Master Control Panel was inspired by the Master Control Program in the original Tron film. It can’t really control anything, it is more of a “WiFi OSC Router”, but it’s hard to get excited about 3D-printing that, so, it’s the MCP. To CONTROL the MCP, there seems to be two scenarios …
  • MCP Electronics
    The adafruit Feather M0 WiFi arduino board has turned out to be the perfect board for the Master Control Panel. There are many pre-made ‘wings’ that can connect together through a common set of pins, including the OLED screen on the top of the MCP, and the servo controller. Since the board diagrams are available …
  • MCP Printed Case
    The case for the Master Control Panel could have been a cardboard box and duct tape, but that wouldn’t be robust enough to handle an on-set environment. So, I 3D printed a case out of nylon and aluminum, from Shapeways. It is light, and flexible, and strong. I was able to download digital models of …
  • Master Control Panel
    REBOOT This camera robot thing became way too complicated. I had gotten all of the individual pieces working, thinking that the whole thing would come together piece by piece. As started drawing diagrams of the wiring, it quickly became apparent that I would have to minimize the wires. I want the bot to have complete …
  • cambot mcp
    It’s been more than a year since I first set out to make the camera move around in a repeatable way. Sure, I was busy with another Chinese action movie, and life and such, but mostly it’s taken this long because building a robot is hard. I knew it was going to involve challenges, but …
  • Vrchitecture
    I was looking for a practical project to explore real world scale and photorealistic lighting in VR. My friend Susie is an architect. She is working on a house for a client, and she wanted to see if VR might be useful in her pipeline. The house was designed in SketchUp, then Revit. I took …
  • robo cam
    Now that I am able to control the camera, I was able to get back to the automation goal. I originally set out to AUTOMATE the camera, but I was just thinking of the camera controls – focus, iris, f-stop. And then, I figured that if I was going to automate the camera in a …
  • Wired Camera Controller
    The Blackmagic Micro Cinema Camera showed up at the end of March. By the time it arrived I was knee deep at work on a Chinese action film and didn’t have a lot of free time to focus on it. After playing with it a few times I realized that the camera controls are an …
  • BLE & MIDI
    The ultimate goal, the reason I started mucking about with Arduino, is to be able to control the camera wirelessly, in a repeatable way. If the camera ever ships, I will be able to test these theories. For now, I’ve gotten the bluetooth and USB controllers to work, as far as I can tell, but they are …
  • MIDI to Arduino – USB Edition
    Yet another delay in the camera shipment date. And, because I’m an optimistic fool, I returned the cheap-ass on-camera monitor I’d gotten, and back-ordered the on-camera monitor from the same company the camera is back-ordered from. At this rate the camera and monitor will ship in January. As I wait, I forge on with the next phase of the …
  • Ard-wii-no
    So, as I wait for the camera to arrive, I have been refining the control setup. I got it to work with wires, made the PS3 controller drive it over USB. Then I got rid of most of the wires and got LANC working, triggered off of the USB controller. The circuit and sketch are …
  • Past the Breadboard
    I haven’t dallied with electronics since high school. I soldered robot kits, and light sensitive buzzers. One summer I played with etching my own circuits. I couldn’t draft or silkscreen the boards, and I ended up drawing them with graph paper and a magic marker. The etching chemicals were toxic, and the experiment was short …
  • Controlling LANC with a PS3 Controller
    While I wait for the camera to ship, I have been playing with making the LANC control work. I found lots of very helpful posts: Control Your Camera RF Explorer Video Vielseitig Verwendet I’ve been able to cobble together a simple circuit, and mix the sketches to make the arduino use the button presses on …
  • Arduino Camera Control
    I have always wanted to be able to control a camera’s settings with midi. The ability to adjust any setting – iris, focus, zoom, gain – to match a beat or just to have a repeatable combination of effects. When the Blackmagic Micro Cinema Camera was announced, it seemed like it might give me that …
