This is a special controller that [Gary Scott] built to help train camera operators. The pan and tilt controls on high-end movie cameras use wheels to pan and tilt smoothly. This rig can be built rather inexpensively and used to practice following a subject as you would with a camera. This is where the project takes a turn into familiar territory. [Gary] set up a system so that you can play the game Quake using this controller, with your feet doing the rest.
The pan/tilt controller uses two heads from an old VCR. They are mounted above the guts from an old ball-type mouse. A couple of rubber belts connect the heads to the two mouse bars that are normally rotated by the ball. This gives him control of where the Quake game is looking. But he still needed to be able to move, jump, change weapons. and shoot. So he built a second controller for his feet. It uses a CD and some switches as a joystick, and a set of buttons for the other controls. He actually rigged up solenoids to each of those foot switches to physically press keys on a keyboard. You really must see it for yourself. We’ve embedded his set of videos after the break.

[Chris] put together a bunch of common components to create this wireless pan and tilt system for a security camera or a robot.
The motorized base is simple enough, using two servos to make up a mount for the digital camera. In this case he used a parts package which is designed to mount the servos perpendicular to each other. You could also 3D print, our build your own brackets quite easily. The control circuitry consists of a pair of PIC 18LF4520 microcontrollers and a set of Xbee modules. This is where the wireless connectivity comes in.
On the transmitter side, a pair of potentiometers are read by the microcontroller’s ADC and translated into position values. The receiver takes those values and drives the servo motors accordingly. In the clip after the break [Chris] is using micro trimpots which require a screw driver to adjust. You might want to hit the parts bin and see if you can get some that have a more user-friendly shaft or knob.
Unfortunately this system doesn’t transmit video. But WiFi webcams are getting quite affordable so that might be a good option in this case. Continue reading “Wireless Camera Mount Offers Pan And Tilt Functions”
Tired of fighting Windows mobile on your HTC handset? Now you can fight a beta ROM of Android 2.1. [Slm4996] has put in a flurry of work over the last few days to get Android 2.1 running on the HTC Kaiser (aka AT&T tilt), Vogue, Niki, and Polaris. Right now everything except the camera and bluetooth is working but there is a bug tracker to help with troubleshooting any undiscovered issues. If you want to try it out but don’t want to flash the hacked ROM to your phone you can run it beside Windows Mobile by using HaRET.
Correction: The title of this post originally read “Droid 2.1” in error. We have corrected it to read “Android 2.1”. [Thanks GuyFrom7Up]
