Configuring the Raspbian strech for the XPT2046 3.5" touchscreen

I have a Raspberry Pi 2, and recently received an XPT2046 3.5" touchscreen for it. The instructions included were spotty at best, but basically boiled down to replacing my kernel and some other random files, crossing my fingers, and hoping for the best. This is not how I wanted to install it so I took to Google searching for answers. I have mine

BC895XLT Programming Manual

While looking for Linux software for my old Uniden BC895XLT, I found reference to a (now missing) BX895XLT Programming Manual. I was able to dig it up on Archive.org, and have reproduced it on my own website for posterity.

Mounting a SMB share from a Transporter on Linux Mint 18.3 Sylvia

I have a neat little device, though rather aged, called a Transporter. Basically I get the benefits of cloud storage, but I have to buy the disks, pay the electric and internet bill, and find somewhere to plug it in. When I purchased it, I was running all Windows machines. Since then I have transitioned to almost exclusively Linux. Unfortunately

Configuring the screensaver in Linux Mint MATE

I'm running Linux Mint MATE 18.2 (Sonya) on two PCs, and one of the things that I've found annoying is the inability to configure the screensaver in mate-screensaver-preferences. It all looks just like xscreensaver, but it's missing bits. My goal was to display a slideshow of pictures, located on a network share, without any panning or zooming or

Weather tools for migraine sufferers

I fall under the category of Chronic Migraine Sufferer, although my migraine is the lovely kind that started a few years ago and hasn't stopped yet. Regardless of your type of migraine, it's quite common to have weather changes as one of your triggers. Maybe you've found that usually when it rains or a storm system blows in your migraine appears,

Amazon Music Player and Chromium on Linux Mint

I run Linux Mint on my primary desktop. I also have a subscription to Amazon Prime. My music tastes shift around and I slowly drift between the various music services I have access to, as well as my personal collection. Recently I tried the Amazon Music player in Chromium 59 on Linux Mint 18.2. This was my first time attempting to play music from

GetSimple Blog and Time Zones

I use the GetSimple CMS and the GetSimple Blog Plugin on my website. Today I was informed by a friend that one of my recently posted blog posts was blank. After a bit of troubleshooting I finally narrowed it down to the fact that the posts were showing a posted-time in the future, and thus hadn't posted yet. I hadn't noticed this as once

Extracting a JPEG header with Python

A friend and I have been playing around with capturing images from LilacSat-1. Data loss is not unheard of when trying to recieve data from a small box hurtling through space. One of the issues we've run into is missing the first packets that include the JPEG header (for the sake of simplicity, we're going to temporarily redefine "JPEG

Negative PPM value for RTL_FM

A friend was setting up an APRS i-gate with a Raspberry Pi and an RTL-SDR receiver and ran into the issue that he needed to configure it for a negative PPM value for frequency correction. When providing rtl_fm with the PPM correction, it expects it in the format of rtl_fm -p nn where nn is the PPM value. The

Limiting my Caps Lock binding to Minecraft

I previously wrote about binding the left mouse button to the Caps Lock key. My goal was to use it specifically for Minecraft, however my implementation was broad enough to cover the entire OS. I've since written a wrapper script for the Minecraft launcher to deal with this. Let's take a look: MCRUNNINGFILE=~/.minecraft_running First off we need
