GoPro Hero3 Panorama Rig - No-Parallax

thingiverse

I've created a custom no-parallax GoPro Hero 3 rig for easy 360x180 spherical panorama capture. The setup involves a wooden base, 608 bearings, and two HK-15178B servos, which provide precise control over the camera's movement. Additional parts required include 3 x 15 mm wood screws, a 4 mm by 10 mm bolt, washer, and optional light GoPro mount (goprolight.stl) with nut. To assemble the rig, secure the bearing with two servos, ensuring they're firmly attached using zip-ties and additional screws and washers. For tripod mounting, thread the small gear with a 1/4" thread to accommodate standard mounts. A mini-USB power cable or emergency USB charger will provide power to the rig. The setup can be controlled via Arduino board, Raspberry Pi, or RC receiver, while an Arduino Uno or Mini and 2-cell lipo battery would ensure reliable operation. I've developed a custom code (sweep_modified.go) that automatically controls the camera movement using GoPro time-lapse mode in conjunction with an Arduino shield. The rig captures images every 5 seconds for a specified duration of approximately 30-40 seconds. Here's the modified sweep Arduino code: ```java #include <Servo.h> #define DELAY_BETWEEN_FOTOS 5000 // ms delay between fotos, time enough to grab next foto const int POSH_2START = 45; const int NUM_STEPS = 11; int myservoh.attach(10); int posh = 90; int seqh[] = {0, 22, 45, 67, 90, 112, 135, 157, 179, 180}; // move in sequence: vertical horizontal - vertical horizontal (in sequence). int del = DELAY_BETWEEN_FOTOS; Servo myservoh; // declare variable void setup() { delay(5000); myservoh.attach(10); // Attach servo to pin delay(del *3); // wait before doing anything for(int sekv = 0; sekv < NUM_STEPS -1 ; sekv++) { moveh(seqh[sekv]); Serial.println(posv, DEC); movev(seqh[sekv + 1]); Serial.print("\t"); Serial.println(posv,DEC); } Serial.println(); }
