Creating a Swapfile in Ubuntu for the NVIDIA Jetson TK1

October 4, 2014 kangalow 2

The NVIDIA Jetson TK1 has a relatively small main memory for running memory hungry applications like Chromium and compiling large programs. By creating a Swapfile, the Jetson will seem much snappier when a bunch of memory is being consumed. Here’s the video on how to create a Swapfile: You can Read more …

Automount SSD Disk on Ubuntu 14.04

October 4, 2014 kangalow 1

Coming from other computer platforms like Windows and OSX, it seems odd that local disks do not mount automatically on Linux Ubuntu 14.04. This procedure is usually called automount. Sure there’s the distinction between partitions and volumes and all that, but it still seems rather odd to me. Under Linux, Read more …

Jetson TK1 with Microsoft LifeCam for Vision Projects?

September 13, 2014 kangalow 2

For the vision projects that I’m getting ready to do, I’ll need video streams. There are several ways to get video, but one of the most inexpensive is a webcam. Webcams have been around long enough that support for them is pretty much considered de rigueur. They’re also cheap enough Read more …

The Heat Sink Chronicles: Redemption?

September 10, 2014 kangalow 0

A few days ago I installed a Enzotech CNB-R1 Heat Sink onto a Jetson TK1. As noted in earlier posts, with the heat sink installed the Jetson tends to run rather hot. While the high temperature exhibited is during heavy load, it’s still a little disconcerting to be within 10°C Read more …

Jetson TK1 Heat Sink Temperature results

September 9, 2014 kangalow 2

After installing the Enzotech CNB-R1 Northbridge heat sink, I ran a temperature test using the CUDA Smoke Demo. Basically start up the demo, and take temperature readings over the next 30 minutes or so at 5 minute intervals. At the end of the demo close the Smoke window. Afterwards I Read more …

Replacing the fan with a heat sink

September 5, 2014 kangalow 1

The NVIDIA Jetson TK1 is a nice development board. With that said, the little CPU fan cooler squeals like a stuck pig. It’s not horrible when you’re in a noisy area like a lab, but if you’re working in a quiet room the whine can be very wearing. I decided Read more …
