SVL: Raspberry Pi Zero Camera Car with Streaming Video

[ CabCam posts ]

We're still tuning the software and streaming setup, but the hardware looks feasible.

This is a Raspberry Pi Zero W with the Zero Spy Cam and a Juicebox Zero battery board connected to a 2000mAh Li-Ion battery. A completely self-contained camera setup that easily fits on a HO flat car and can stream video over existing Wifi. If I stack the components more intelligently, it fits on a much shorter car, too.


During the Show&Tell at tonight's club meeting, we demonstrated the setup at the workbench and on the Welztalbahn.


Members on the video conference were able to observe the trip with only a few seconds delay. This worked much better than expected.

So far, so good. The real test will be trying this out at the club.

Snoqualmie Falls Hydropower Museum

Image
Generator 5 was installed in the underground cavity of plant 1 at Snoqualmie Falls in 1905. It has a generation capacity of 5600 kilowatts. It uses a Francis turbine, which is more efficient than the Pelton wheels used in the other 4 generators installed at plant 1. The water enters the turbine from the sides and then falls straight down from the center of the turbine into a draft tube. The energy of the flowing water is transferred to the shaft of the turbine in form of torque. The shaft is connected to the generator, visible in the rear in the photo at the top of this post. In 2011 the plant was modernized and generator 5 was moved from plant 1 to the hydropower museum. "Wow!" The shops building was moved here from its original site and has various artifacts and equipment that was removed from the plant's underground cavity and control room. Control panel. Knife switches.

Sunday: Kandersteg

[ Three Tunnels and Winter ] Kandersteg station has the control tower right on the platform at track 1. However, it appears the big control table is no longer in use. Instead, everything's controlled via computers in a back room. Here's the line diagram schedule. This photo was taken through two windows and blinds, so unfortunately it's hard to make out train indications. However, I believe the rather tight column of red lines in the middle of the screen represents the auto transport trains traversing through the Loetschberg tunnel. As soon as the sun disappears behind the mountains, it gets cold. I didn't want to stand here for another 30 minutes until the RegioExpress to Bern was due, so I decided to take the RE 4275 through the Loetschberg tunnel to Goppenstein, where I'd have about 5 minutes to get to the other platform for the return trip and on to Bern. While waiting for the RegioExpress, this KLV train with double-header DB class 185 barrels through the stat...
