A while back, I saw a picture online of a restored antique radio that caught my attention. The accompanying post described the process of restoration. I’m not into radio restorations but I think the old wood radio cases are very “cool”. I also recently contributed to a Kickstarter project for HDMIPi, an “affordable 9 inch High-Def screen for the Raspberry Pi”. I thought that I might place the screen and R-Pi inside an old radio case.
After looking on eBay and craigslist, I could not find a suitable enclosure for the HDMIPi and paper mockups showed the screen to be a bit small at a distance. I used my old original iPad as a test device for measurements and viewing. I liked the viewing and pixel size of this its screen.
Well, the HDMIPi was going to be slow in coming (still is) and I saw (fairly) inexpensive 1024 X 768 iPad displays and driver boards on eBay. I also found a old 1942 Crosley radio case that had a front cut-out that was very close to the iPad screen size. The radio portion was not fixable so the case was reasonably “priced”. I bid on it … and won. I then had yet another project demanding time 😉
Raspberry Pi database, mongodb, Raspberry Pi
I’ve been looking at noSQL databases in conjunction with Node.js. I have several Raspberry Pis that I have been using as development and test platforms. I have had good success with couchDB but have seen more examples and deployments using mongoDB. MongoDB is clearly developed on Intel processors but has been ported to non-Intel processors with different “endian”. Getting mongoDB to compile and run on a Raspberry Pi has been a challenge — as seen by the dearth of info when Googling. I did run across a couple of useful sites with links and directions on how to compile mongoDB on the R-Pi BUT both had a few problems. I’ve managed to get mongoDB version 2.1.1 working.

As of January 21, 2013, I have found the following work for me:
node.js can and should be installed from source. It compiles and installs correctly for versions > 0.8.10. More general info can be found at node.js. Detailed instructions for installing on the R-Pi are on Jeremy Morgan’s blog. Most current version is 0.8.18.
CouchDB can be installed via an “apt-get” for raspbian. The latest version I’ve seen is 1.2.0. More info on CouchDB is at couchdb.apache.org.
Raspberry Pi Raspberry Pi
I ordered a Raspberry Pi Single Board Computer on the first day offered, on leap day, February 29, 2012, and received it on June 4, 2012. A bit of a wait but I was excited to “play” with a $35, full-blown Linux-running, HDTV 1080p output, computer — and it was all for a great cause. The Raspberry Pi Foundation is trying to do something about the situation where computers had become so expensive and arcane that programming experimentation on them had to be forbidden by parents; and to find a platform that, like previous generations of home computers, could boot into a programming environment.
I’m planning on using multiple R-Pi SBCs as mini servers and for real-time sensing and control of various devices. Now, where did I put my soldering iron and multimeter?
