Embedded Systems: February 2011
http://dvgadre.blogspot.com/2011_02_01_archive.html
Saturday, February 26, 2011. During my recent visit to the CeC festival,. I met Abhinay Khoparzi and he showed me a rebuild of Monome music controllers. I just fell in love with these. I am now planning to build my own using the Arduino. Platform. The Monome website shows various applications. Other than generating/controlling music. I have some applications of my own in mind, such as a controller for the ceiling lights I am planning to install in my office or RSS feed display. Links to this post.

Embedded Systems: November 2006

Thursday, November 09, 2006. LED as a Light Sensor and more. Recently got interested in the use of a normal LED as a light sensor. Its amazing, but there seems to be some conspiracy on the part of the electronics professionals, in keeping this interesting and wonderful physical phenomenon, hidden from public. Or is it ignorance? The only book that talks about this is by Forrest Mims. We just published a Design Idea in EDN on this topic. Posted by Dhananjay Gadre at 6:26 AM. Links to this post.

Saturday, October 28, 2006. Travelogger: A Gadget to Record and Document Your Travel Memories. I just came back from a small trip to Manali and Kullu. While there, we also visited Rohtang Pass (Altitude: 4000 meters) and Manikarn. Manikarn has hot water springs and we cooked rice and potatoes in the boiling water (temperature: about 95 degrees Celsius). Here is a technology solution:. Camera is similar to the ones in mobile phones these days. Not too fancy. Fixed focus, hands off operation. Eventually, a...

Wednesday, April 05, 2006. Stephen P. Morse - and the 8086 Book. Stephen P. More is the Grand Daddy of the processor running your PC. He was the lead designer of the 8086. He also authored a short and sweet book titled, "The 8086/8088 Primer", which I liked very much as a student, way back. It turns out that Mr. Morse has decided to make the book available online here on his website. Its a wonderful read. Thank you Mr. Morse! Posted by Dhananjay Gadre at 12:27 PM. Links to this post.

Sunday, March 05, 2006. On Death and Embedded Systems. The queer thing about death is that you die only once. And by then its too late. You of all people cannot participate in your own death. Why am I talking about death and whats it got to do with Embedded Systems? Something happened today, about which I wrote on another blogsite. My mind has been thinking about death in general since then. Name picked from the Access Database. Time and date, again as detected by the sensor chip. Links to this post.
