Recreating the Sony Aibo robot dog using a pile of cheap servos, 3 axis gyro, the camera, wireless, neopixel lights, LiIon power, etc. Shoulder joints, body shell and chassis 3d printed. Total cost is around $150. Locomotion is largely based upon the designs documented by Cynthia Brezeal Ferrell (MIT mobile robots lab, under Prof. Rod Brooks) in her PhD thesis for the hexapod robot, Atilla/Hannibal. The first attempt…

Any pictures, write up, Github? This sounds awesome! I also remember reading awhile back about the huge market for upkeeping these things once Sony abandoned it. Perhaps you're onto a business!

No, this is the first I've spoken of it, really. I've a few notebooks filled with sketches, thoughts, designs, etc. and a pile of prototype joins and brackets littering my workbench. It's actually a very challenging project from an electrical engineering and mechanical engineering standpoint. The Sony team were superstars. I still like the "mutant" prototype the best as it had the most character: https://www.youtube.com/watch?v=gfHape9Y31Q

In the mid 2000s, I had written some code for the Aibo to let it read books aloud.

Flash forward toa couple years ago. My kids saw some video of me with the Aibo Reader project and wanted an Aibo of their own. Unfortunately, the Aibo as a product is dead. The batteries are now dying and irreplaceable (thanks to Sony and their idiotic insistence upon DRM - it's not enough to merely provide electrons, the battery must also know the secret handshake in order for the Aibo to accept it. Maddening!!!) And those few used Aibos that do have working batteries are dying from other issues related to mechanical failure (mostly clutches in the head/neck assy.) yet command a premium price.

So now, my kids still want an Aibo. I got to thinking about how far technology had come in the past 20 years, and started wondering to myself if I could build a facsimile with the RPi. Thus the birth of this little side-project.

I have one running PiAware: http://flightaware.com/adsb/piaware/ I built a "Kitchen Dashboard" last year: https://gavinr.com/2016/01/10/raspberry-pi-kitchen-dashboard... And of course you have to build a RetroPie: https://retropie.org.uk/

+1 for PiAware. It's just about the easiest project and a good intro to the Pi.

Other things on Pi in my house: OpenVPN server (http://www.pivpn.io/) and Node-RED (https://nodered.org/) for collecting temperature data and pushing to Power BI.

I used one to build a photobooth for my wedding. The raspberry pi controls a DSLR camera to take 4 photos, stitches them into a 4x6, prints the photo and uploads everything to a Google Photos album which was displayed live on a projector.

I'm also in the process of building a photobooth. Using the standard Pi Camera module + a Pimoroni Unicorn Hat HD to give people a prompt when the photo is about to be taken. It'll then publish the photos on it's own internal webserver that'll be visible on another Pi for easy emailing / browsing and tweeting! Going to pack it all in an transparent enclosure that looks like the approximate shape of an oversized DSLR.

Nice, that sounds quite a bit more compact than mine. Having really good quality photos for us to keep was the biggest priority so we settled on a DSLR and dedicated flash. Along with the printer, I ended up installing it all into an old speaker cabinet which ended up fitting everything perfectly. I do wish I wasn't living in an apartment at the time and had access to some better tools to build a proper enclosure though.

Created a temperature sensor system that can generate alerts whenever temperature or humidity goes above or below a limit configured by the admin portal. Along with Elasticsearch and Kibana graphs can be generated and also data can be seen on top of the floor plan to understand hot and cold spots in a building.

The repository below contains code and instructions on how to setup the Raspberry Pi device to report temperature/humidity data along with manual alerts to the server: https://github.com/ankurp/thermostat-sensor

The server code where data is received and saved, notifications are sent, and the entire system configured via the admin portal is here: https://github.com/ankurp/thermostat

I built a remote controlled cat feeder with a simple servo controller loosely based on this blog: http://drstrangelove.net/2013/12/raspberry-pi-power-cat-feed... Then I added a server instance and an iOS app so I could schedule / manually control feedings remotely. Great for short trips.
