Getting Started with Amazon FreeRTOS and the Espressif ESP32-DevKitC
AWS Documentation and Drift AWS already provides a getting started guide in the Amazon FreeRTOS documentation. But, when I was following it trying to get the demos to work I was unsuccessful. After a bit of investigation it became clear that the documentation was out of date. Following submission of feedback to AWS the documentation was promptly updated with up to date information.
Now, the Amazon FreeRTOS is a very active project and is changing continously.

Ubuntu 18.04, Nvidia GeForce GTX 1060 3GB OC
There are multiple options for running an Nvidia GPU mining rig to mine cryptocurrency. You can use Windows or multiple flavors of Linux. I tend to use Ubuntu for most of my Linux needs, and so I used it for my rig as well. Initially I wanted to use a completely headless install with only a CLI system. I didn’t see a need for X. That didn’t work out because the Nvidia driver and the customizations required to overclock the GPUs required X.

LANcache on Ubuntu Linux for PS4 and PlayStation Network (PSN)

Polar H7 Bluetooth LE Device Name
While messing around with my Polar H7 trying to figure out how to read real time heart rate information I inadvertently overwrote the device name. I didn’t even realize that this was possible, but apparently it is.

This made life a bit harder. On my Android devices when scanning for the device I’d just get a blank name.

Polar H7 Bluetooth LE Heart Rate Sensor on Ubuntu 14.04
I recently picked up the Polar H7 Heart Rate SensorĀ (Bluetooth Low Energy). The long term goal is to connect up the sensor to my HTPC running XBMC so that I can see my heart rate on the screen while I work out. I usually work out to music playing on the HTPC or watching P90X videos. So, it’d be nice to be able to see the heart rate information real time as well as record it in a file/db for historic purposes.
