Self Driving Car: Setbacks and progress

Setback: Ok - so I started assembling the PiCar that will use Google Coral and I realized that I put the heat sinks on when I shouldn't have, as the HAT board doesn't give enough clearance.

However, I managed to successfully flash the Jetson Nano.

Assembled most of the hardware.  Unfortunately I didn't get the needed batteries with my package - so I'm off to the Internet to find some batteries.

Here are some pictures of my build of the Jetbot so far.

Home built Hadoop analytics cluster: Part 3

Home built Hadoop analytics cluster: Part 3 In my previous post I covered Bill of Materials (BOM), hardware assembly, and installing Linux (Ubuntu).  In this post I will cover how I installed Ambari. Installing Ambari Rather than build from source, I opted to use the distribution from Cloudera (formerly HortonWorks). Ambari 2.7.5 requires official support from Cloudera, so I went down to 2.7.3 which doesn't require a support agreement with Cloudera. Install some pre-requisites sudo apt install python-dev sudo apt install gcc Add Cloudera as a distribution sudo wget -O /etc/apt/sources.list.d/ambari.list http://public-repo-1.hortonworks.com/ambari/ubuntu18/2.x/updates/2.7.3.0/ambari.list sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com B9733A7A07513CAD sudo apt-get update Verify packages show up apt-cache showpkg ambari-server apt-cache showpkg ambari-agent apt-cache showpkg ambari-metrics-assembly Install and setup the server on primary sudo apt-get install ambari-se

Home built Hadoop analytics cluster: Part 2 In my previous post , I went through my overall plan that I will be following, along with goals and topics that I will be covering.  In this post, I will cover the initial building out of the cluster. [ Bill of Materials - BOM ] [ Hardware assembly ] [ Installing and configuring Linux ] Bill of Materials - BOM Item Price Link CPU $139.99 Amazon Motherboard $71.99 Amazon Memory (32 GB) $109.99 Amazon Storage (500 GB) $57.99 Amazon Power Supply (600W) $62.99 Amazon Case $68.99 Amazon Total $511.94 *** Total estimated price as of 10/12/2020 Does not include shipping/taxes Obviously, you can swap out components as you see your needs fit.  I did not want to make a high end workstation with GPU, opting to use a CPU that had graphics built in.  I did opt to get 32 GB memory and 500 GB storage - I could have gone down to 16 GB for memory and 250 GB for storage, but I feel that memory and storage is something that I always seem
