Walking aid for the blind

It’s been a long time since I’ve done anything in electronics. Well, not really; I’ve only kept from publishing them. I’ve spent the past few months working on my undergrad project. There were mini-projects I undertook from time to time during this period, but this was my first major project that would be under some real scrutiny and I had to concentrate on it. This is essentially why I have been too offline than is normal in terms of publicising my real work, although you would find my non-tech thoughts spread around the inter-webs (if you’re looking really hard, I must add – which is a very sad realisation). So, here, I bring to you my prized brainchild – the walking aid for the blind.

Improving MIDI…

I have been having a great time concentrating more on my work with electronics. Seems like the days are getting better. It’s just been two days since I wrote codes and had fun with the result, and I somehow got bored playing the same instrument. So, I decided to develop my MIDI music maker a little further. Most controls are the same; I’ve added functionality for instrument change and pitch amplitude manipulation. I might not stop here and I’m hoping this project ends up as a consumer product.

Again, I can’t really disclose any coding details, not because I don’t want to; there is no expectation of production quality from the devices I own. The day I find a way to create a good tutorial, I will.

Working with MIDI…

This post is going to mark a paradigm shift in my blogging. Most of my earlier posts seem to deviate from the point I try to make. I’m not promising all my posts will be to the point from now, but you can certainly expect to get a higher content-to-crap ratio.

To begin with this new me that I’ve just discovered, let us just cut it short to the video I made for the MIDI music maker. All the details regarding the working has been explained. With a sufficient amount of motivation, I’ll probably post a tutorial so that you can make one of these.

One more thing – I’ve never not bragged so let me just go ahead and tell you all that the embedded video here is called using special code that should ideally support HTML5, which means you’d could as well watch the same video on your phone without a hitch.

Morse code generator using Arduino…

‘Micro-controllers’ was a theory chapter in the Computer Science course I had in my pre-university years, and yet I hadn’t really seen one up close until the end of my first year at MIT, Manipal. Learning of micro-controllers was not a big deal; the real deal was writing a micro-controller program on your own without help(and I don’t mean simple programs that involve flashing LEDs in a sequence at best). Tens of my colleagues have made robots using micro-controllers, but only because they were parts of guided tours. They hadn’t much to do with the robots they owned. Not being rude here, just ask yourselves, “Am I capable of writing programs for the chip from my bot and incorporate it in a different bot?” Well, I am. Now, this is certainly not the first thing I’ve ever made; it’s just the first thing I have shared for everyone to see.
