Re: TimeLapse causing Network drop

Indeed I've been using an ralink adapter. I'll try another make and seeing it helps.

TimeLapse causing Network drop

So, when using the raspistill timelapse function, combined with a wifi dongle, I've noticed that after a little while, I eventually lose network access on the Pi completely. It continues to run, finishing the timelapse and encoding it per my script, however, I get no network (wired or wireless) unti...

Re: Horizontal lines with video, not stills

There's a topic about this already on this forum. I had the same issue. i I tried every little USB-based charging brick, and USB cable I could find, and still had the problem. I finally fixed it by switching to a Motorola 850MA charger which had an integrated USB connector on the end. No need for se...

Re: Flashing band across video

So, I had been using a usb cable and various USB chargers to test, like an iphone charger and the charger from my Nexus 7. All of those consistently gave me the video bands. Finally I actually switched to a Motorola charger which did not have a separate cable- it plugged directly into the wall and h...

Re: Flashing band across video

Same issue in natural light. Although not as noticeable. I tried different power supplies and USB cables. Tried repositioning the camera further away from the Pi. NO matter what, a slight flicker/banding is still visible. Picture quality looks great other than that. Very disappointing though. Hopefu...

Re: Flashing band across video

I've noticed the same banding when recording video. I've only tried in fluorescent lights indoors so far, and in the same room with the lights off. horizontal bands show up every time so far. I'll try to give it a shot in bright natural light tomorrow. Stills look fine.

Re: Simple PIR project - Can it be done by a Newbie?

Easy- take a look at my code for the cat poop detector: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=37&t=26200 It uses a cheap PIR. There's a line I commented out which will play an MP3 when motion is detected. Just do a "sudo apt-get install mpg321" for a nice console mp3 player. Just get rid...

Raspberry Pi Cat Poop Detector

This started as a project to simply annoy my wife into cleaning the cat box. Along the way, I learned quite a few good tricks. Basically, I attached a PIR motion sensor to the raspberry pi, along with a webcam. I wrote a little python script that, when it detects motion, snaps a picture from the web...

Re: Siri: Open my garage door..

Great work. There's an alternative to Siri proxy called Siri server core that i played with some time ago. Its written in Python and works like a charm with lots of great plugins. I thought about doing a project similar to this myself but never got around to it. https://github.com/Eichhoernchen/Siri...

piRoomba

Here's a quick (shaky) video of my Raspberry Pi controlled Roomba. For this project I used the Raspberry Pi model B, an energizer rechargeable battery pack, a battery powered speaker, which also had USB out, powered hub, usb wireless, usb webcam, and the Roomba USB>Serial cable. Oh, and an Iphone5 t...
