In this video, I’m riding my bike south towards San Francisco around the north tower of the Golden Gate Bridge. I used a GoPro HERO3+: Silver Edition
In the video poster frame, you can see the water just outside San Francisco Bay in the gap between the orange barriers. That doesn’t help my acrophobia, especially knowing that there is a 227 foot drop to the water. And it’s only blocked by a temporary Cyclone fence.
There’s almost always a constant wind off the Pacific Ocean, blowing across the bridge to the east . This year, the bridge authority retrofitted the railings to withstand 100 mph gusts. Now, when the wind is >25 mph, the new sidewalk railings emit a deafening hum that can be heard miles away. Add the sound of cars and trucks three feet away going south at 50 mph, it’s not a wonderful experience.
I just try not to look to the right.
Update (January 25, 2021) My Raspberry Pi powered webcam is now showing the Jordan Park Neighborhood in San Francisco, California. The Raspberry Pi Model B, Rev 2 is using the Raspberry Pi High Quality Camera (with the Raspberry Pi HQ Camera Lens – 6mm Wide Angle) and is running Motion (pi_buster_motion_4.3.2-1_armhf). Details to follow.
(Original post) I built a streaming webcam showing the view from my downtown Oakland apartment in November 2012. I used a Raspberry Pi (Model B Revision 1.0) and the Raspian Wheezy (2012-10-28) image. For the webcam/web server software, I used MJPG-streamer. The problem with MJPG-streamer is that if the images/stream is available on the internet, then anyone can access the software.
Recently my Raspberry Pi began to lose the WiFi connection. In researching various solutions, I disabled WiFi power management on the Edimax EW-7811Un
I found a nice script for “Rebooting the Raspberry Pi when it loses wireless connection“. It’s a script that runs in crontab and checks for a network connection by pinging a local address. If the ping fails, it restarts wlan0.
The checkwifi.sh script worked great, but then I had an issue with the video stream image oscillating. The image would continually go between light and dark and the only way to stop it was to restart MJPG-streamer.
I decided to update to the current Raspbian Jessie with Pixel and some other webcam software. The Motion-Project seemed not to difficult – I could use it as a streaming webcam. I decided to use Motion 4.0 and Kenneth Lavrsen’s Motion 4.0 Guide to help set it up. I don’t know if the image oscillation is an issue caused by using the Creative Live! Cam Chat HD
From the National Park Service:
“On June 19, 1912, Fort Winfield Scott was established in the western part of the Presidio as a coast artillery post and the headquarters of the Artillery District of San Francisco. Fort Scott housed seventeen Endicott-era gun batteries that were constructed, armed, and manned between 1891 and 1946. In 1922, Fort Scott was designated headquarters of the Coast Defenses of San Francisco, which was renamed Harbor Defenses San Francisco (HDSF) in 1925. As HDSF headquarters, Fort Scott controlled most other army forts in the bay area, including Forts Baker, Barry, Cronkhite, Miley and Funston. Only the Presidio of San Francisco and Fort Mason did not fall under Fort Scott’s command.“
