Its been a while since this project and I really havn't had the time to write a blogpost in a while. Last year, I made an IoT light for the Element14.com roadtest plus where I used a lot of technology from Texas Instruments and Wurth Electronics. TI was kind enough to showcase the build on...

I wanted to do a video series on IoT, how to design IoT Devices and how one implementation is different from the other. I weight out the pros and cons of each technology and try to find a best case scenario.
Introduction In the last post, I described the hardware part for our robot which uses the Seeed Studios GrovePi+ since I am yet to receive my kit. In this post, I talk about the software part and making the robot move. Lets see what we can do. Setting up the RPi I have already mentioned... Continue Reading →

Prelude In the last post, I started by linking to the various resources and buying the basics and then testing the 'air' by getting the motors to run. In this post I will share my experience in building my own frame. The frame Since the BLDCs and ESC are OK tested at this point, I... Continue Reading →
Introduction I am waiting for my stuff to get delivered which are basically parts and parts. One of features of my design is that the raspberry pi center piece is portable, ie it can be moved from one location of the house to the other. For this I needed to add a battery backup which...

As I wait for the parts to be delivered, I started work on the case for the RPi. This is the center piece for my demo and with my limited carpentry skills, I set out to make a box. I usually start by making a 3D to scale model in Sketchup so I know exactly... Continue Reading →
I've been using the raspberry pi for some time and since I use it as s headless device, I have missed the shutdown button. After some experimentation, I have come up with a simple solution. There are many ways to implement a shutdown script, but I am going to walk through the two simplest ones.... Continue Reading →
