This is part of my project to fit a solar powered RaspberryPi webcam at Mt Lyford that starts here   An excuse for a field trip (to a skifield) on a nice day, is not to be missed, however this trip was all business, with a couple of other things to look at/repair as well. The exact location and mounting method was one of the things on my list.   Snow, ice and the odd heavy machine (groomer) means that unless its well anchored, its very likely to move. Snow is a strange thing, and t ...
Processes, Applications and Function Having resolved some of the hardware issues, it's now time to put some thought into how the whole thing will work. The controller has overall control because it runs 24/7, but could go into a sleep mode when the system is shutdown.   The controller is responsible for :- RTC (Real Time Clock). Battery charge. Systems power (RPi and Wireless link). Battery voltage. External shutdown button. External Status indication. Receiving future data.  ...

Pi camera update

Posted by mcb1 Top Member Aug 7, 2013
My solar powered  PiCamera installation took a step closer yesterday with the link options resolved. Link The WiFi link for transferring the data requires a directional antenna. The Antenna design needs to be rugged to withstand the hostile environment, as well as the distances.   The links are 350-500m (click on image for full size) Google have some neat features that allow you to view the profile of the line. (Save the line, and then right click on it) While the heigh ...

PI RACK

Posted by mcb1 Top Member Aug 6, 2013
I was fortunate to get my hands on an early release of the PiFace PiRack. (I prefer to use the small i in the blog)   This has been mentioned in the PiFace documentation, but there was little other information.   The PiRack is designed to extend the GPIO pins of the RPi (Raspberry Pi) out to a series of right angle headers, and an end connector. You then stack 4 x PiFace Digital boards (or any other boards) onto the connectors. A second PiRack fitted to the last connector gives the ...

Pi Webcam

Posted by mcb1 Top Member Aug 3, 2013
I was fortunate to receive a Pi camera to use as a webcam. This is no ordinary straight forward project but is located on a skifield www.mtlyford.co.nz.   To add to all the problems associated with the environment, the location has no cabling for power or communications. Hence the project requires Solar and WiFi over approx 400m, meaning some custom aerials as well.   To save power the controller needs to initiate a shutdown, and startup at set times, as well as orderly shutdown an ...
