Raspberry Pi Camera Module + PiBow
Previously I show how to mount the Raspberry Pi module in the Pimoroni camera mount, but now we need to connect it. Connecting the camera to the RPi is pretty easy if you are careful and there plenty of guides, but I wanted to use it with the Pibow case. The new PiBow cases have a slit for the ribbon cable but if you have the older version, you can make it work. Here is how I did it: Check out this post about using the camera and real-time streaming with mjpg-streamer.
PiGlow from Pimoroni
In a recent Adafruit order I couldn’t resist picking up the new PiGlow for the Raspberry Pi. This is a neat 18 LED add-on that connects to the GPIO header of the Raspberry Pi and communicates over I2C. With the example Python code, I was blinking in color in no time. You can buy them from Adafruit in the US or directly from Pimoroni in the UK. The Pimoroni site has all the links to get you started. I used the link to Jason Barnett’s Gihub which has a in depth how-to and a lot of examples to get you started and playing in color. The LEDs are in a spiral pattern, making for a great binary clock, which is …
Raspberry Pi Camera with Pimoroni’s Camera Mount
In my last Adafruit order, I decided to get the Raspberry Pi camera and the Pimoroni Raspberry Pi Camera Mount. This has been on my to-buy list for quite some time. I first saw the camera in person at Hacker Dojo when Rob from RPi came on his tour in the States. I am really excited to see what fun stuff I can come up with. In the past I have used a webcam on my desktop with ActiveWebCam to stream my entry-way to keep tabs on it. I want to try the Raspberry Pi to replace this setup as well as other projects. I have may have to put a few more cameras to go with all the Pi’s …

Adafruit’s Show and Tell is a must if you’re looking to get ideas on various projects. Ladyada hosts a Google+ Hangout each Saturday evening in which she invites makers to share their latest projects. This past Show and Tell I showcased the USB Tester and a glimpse of the OLED backpack being developed. Enjoy!

Adafruit’s Show and Tell is a must if you’re looking to get ideas on various projects. Ladyada hosts a Google+ Hangout each Saturday evening in which she invites makers to share their latest projects. This last week, I was able to get on and join in. Check it out below! I showcased my Raspberry Pi Motion Logger which you can read about here http://www.mobilewill.us/2012/08/raspberry-pi-and-motion-graphing.html. Have you watched any or shared projects of your own? I’d be interested to hear about it!
Raspberry and a PIR Sensor
Last month I bought a PIR as part of my Adafruit order for Raspberry Pi stuff. This weekend I decided to try and use it with the RPi. PIR Sensor (image from Adafruit) Rear of PIR Sensor (image from Adafruit) Using the WiringPi library, it was pretty easy to get it up and running. Here is a picture of it mounted on top of the Prototyping Pi Plate from Adafruit with double-sided tape. Raspberry Pi Plate with PIR and LED I connected it to GPIO 18 or pin 1 in the WiringPi library. Here is the code I used that blinks the LED when there is motion. I used the same technique as the blinking LED test so that I …
