I wonder how many posts have been made about this so far today? I’d guess a whole bunch, so here’s another. Keith Devlin (The ‘Math Guy’) from Stanford University was on NPR earlier today and had a few fun and interesting facts to share:
I recently ordered a camera module for my Raspberry Pi, and finally got around to installing it this evening, to include the lego tower that it’s perched on. I also discovered that my ASUS AC66U wireless router has enough power in the two USB ports to run a Pi and charge an iPhone at the same time.
The camera works great, it has five megapixels and can produce 1080p photos or 720p video. There are some updates and packages that need to be installed before you jump in, but that really only took about 30 minutes to run through that process, including download time. Step by step guide here.
The pictures from the actual sensor are great, if I have time tomorrow I’ll take the rig outside and upload some photos.
This afternoon I decided to start fiddling with one of my Raspberry Pi’s, I’ve been collecting bits of hardware here and there for a small scale home automation project using some X10 gear. Small problem though, the thing won’t boot now, the SD card seems to be corrupt and won’t take a new image. Not just one card but two out of three.
The cards are a year or so old, purchased them all at the same time from a reseller on Amazon. Turns out, this may not have been a wise idea. After spending some time searching online for similar issues, I’ve found that counterfeit SD cards is a pretty big thing. Not sure if that’s the case here, they all have different serial numbers, but I’ll be reaching out to the Kingston folks later on to see if the cards can be verified.
Using a smaller capacity card seems to work fine, so no issues with the reader on my laptop or the Pi. SD card corruption has happened to me in the past when the Pi abruptly lost power without shutting down first but imaging it again was never a problem.
I think from here forward that purchasing direct from the manufacturer or a trusted reseller is the best way to go, google ‘fake sd card’ and check the results for yourself. In the meantime, card number three has an image and I’m going to try and start working on randomly blinking lights on and off in the house. Eventually I may try to hack my coffee maker.
