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 their power house blog and I wrote a two part series for the same. Continue reading “Designing an IoT Modular Light feat. TI”
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. Continue reading “[RPi Rover] Another Raspberry Pi Robot – Episode 2 – Starting Python”
The author would like to thanks the sponsors Element14, Tektronix, Eclipse IOT, EnOcean, Raspberry Pi, Cadsoft for the tools, parts and budget. A special thanks to the community members for their inputs and suggestions as the project progressed and for providing inspiration as well as encouragement along the path.
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.
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 was shown in my previous posts. In my recent experiments, I found that the Raspberry Pi was rebooting unexpectedly. It turns out that one of the connectors was defective. Still this left me with the question that if I am using a battery, how long will my system stay afloat without power? Hence I setup a little experiment to measure the power consumed by the Raspberry Pi and the results were quite unexpected.

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 what I want. If it seems awkward, I change it. Here is a simple mockup that took 5 minutes!

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.
