I purchased a cheap clone of the Saleae Logic 8 port logic analyser (LA) from Banggood.com on Dec 16th 2014. This page reflects my initial experiments with using the device under Windows 7 and FreeBSD 9.1. The clone does 8 channels of digital capture (no analog capture) and peaks at only 24MHz sample rate, but […]
In December 2009 I rebuilt my home file server to be a FreeBSD 8.x machine with six 1.5TByte Western Digital HDDs in a ZFS raidz2 configuration. From February 2nd 2010 I’ve been sampling the internal SMART temperature senors of each drive every 6 minutes. This post summarises some of what I’ve captured.
This post documents my recent experiments with Oleksandr Tymoshenko’s patches to get the FreeBSD 10-CURRENT kernel running in a Qemu-emulated Versatile Platform Board (VersatilePB) armv6 environment.
Back in July 2007 I purchased a NetYS PE 1000VA UPS to provide backup mains power for my main home FreeBSD server. In the past month I have (finally!) figured out how to remotely monitor this UPS over USB connection from my FreeBSD box (currently running 8.3-PRERELEASE). This post documents the steps required to get […]
For experimental purposes I have installed qemu-devel 1.0.10_1 on my main FreeBSD 8.3-PRERELEASE server (gjabkup2). This post documents for posterity the configuration steps I used to enable networking for qemu-devel instances when launched by non-root accounts and inside jails. The steps were inspired by this post and this post.
I’ve upgraded my home FreeBSD 8 server’s instance of VirtualBox to 4.1.8_OSE, and ran across an issue with my Windows 7 VM. The VM’s primary virtual hard drive (C:) was initially created as 20GB, and I was running out of space to install new applications. This post notes the VirtualBox magic required to resize a […]
I’ve upgraded my home FreeBSD 8 server’s instance of VirtualBox to 4.1.8, and wanted to play with passing USB devices through from the FreeBSD host to VirtualBox guests. This turns out to be supported in only a limited manner — information here shows how we can ensure USB 1.1 and 1.0 works properly, even though […]
