Marcy 2's power plant is overpriced junk from Tower Hobbies. They didn't send the $1.50 of Dean connectors ordered.
The Castle Creations 6 is really badly soldered. The 12-30-4110kV Electrifly has incredibly flimsy wires. It's obviously high flex cable & I should have left the bullet connectors on, but they looked heavier than they were & they easily broke off.
The 1st images at flight RPM were pretty bad. A refrigerator & chair are visible.
Instead of hitting head on, the camera scanned diagonally, causing sheering in addition to vertical compression. At the highest shutter speed, it was still pretty blurry. Each revolution has 6 frames, so forget about lining up a frame on the same spot.
The test harness was pretty unstable. A stable attitude would give better results.
Camera rotation improved matters.
Increasing the camera to 30fps, letting it drop 1/2 the frames, & letting it drop magnetometer samples got more overlap. If there was a way to automatically align everything, this might work. Slow scan 640x480 was useless. The trend is towards lower resolution & higher clockspeed.
Next, we have 160x240 with every frame sent twice to reduce dropped frames & full magnetometer data. A lion is clearly visible.
Finally, a shot in color 160x240 at 24fps, with 1/2 the frames dropped. More detail is recognizable to a human, but probably not to a computer.
It's hardly the sharp daylight footage envisioned, but this is a matter of the size of the lens & the sensor quality, not available technology.
Ride on a monocopter
Since the camera is going to point diagonally, it's hard to envision a target it could use for navigation.
Trying to spin up Marcy 2 outside resulted in the wind taking her off & the mane immediately being attacked. Untangling required destroying the propeller, since press-on propellers can't be removed.
At least it showed daylight improved the picture quality & a monocopter could be very useful for imaging outside.
Automatic placement didn't go so well.
Rotating manually matched a little better, but since the camera was pointing diagonally, it only needed 90 degrees of rotation. If it pointed straight down, it would rotate 360 deg.
There's no way to trigger the camera at any random time. The nearest frame jumps around a lot more as the framerate decreases. The extra processing for color slows it down by nearly 1/2.
Carambola would be real slow.
Now some useful commands for accessing Marcy 2 without compiling a wireless network driver on every computer.
iptables -t nat -A POSTROUTING -j MASQUERADE
echo "1" > /proc/sys/net/ipv4/ip_forward
on the computer with the network driver.
route add 192.168.0.1 gw amazon
on the computer with the ground station.
That there is a board so badly designed, it's nothing but rework. The mane shock was a TO-252 had the lowest current capacity of all the LM317 packages & this board uses a lot of current. If money was infinite, a low dropout regulator would be used.
