I went through all the struggles everybody else seems to be going through to get this screen connected to my Arduino Nano. I had the 5V to 3.3V voltage conversion problem, and the "only works with software interrupts" problem which makes the display run slow. The solutions are not complicated but not very wel …

For some reason I have trouble finding a document which lists the complete IARU Region 1 Band Plans. To end my "can I transmit here" quests, I've combined the information from several resources into a usable graphical representation of all Amateur Radio bands and modes up to 500MHz. I've not listed bands …

It's not until you or someone very close to you becomes dependant on a wheelchair until you notice that the world is not as wheelchair friendly as you might think. Hotel rooms are wheelchair accessable, but the lobby can only be reached by stairs. People with kids can take strollers all the way up to the airplane seat, …

I recently needed to print out a big schematic diagram of the RX/TX board of a Kenwood TS50 Transceiver. This did not fit on a single piece of paper. Instead of downloading all kinds of crappy tools or uploading the image to some "free" site which is going to use it for whatever they think justifies their …

In the past I have used Evernote extensively, it really helped me in my research for this blog and keeping track of meeting notes, todo lists and even making pictures of whiteboards at work searchable. As a product, there is no note taking app that can beat Evernote. But there is a little problem that has become a deal …

It will give you an icon on the toolbar of your Finder, and pressing it will open a Terminal window and …

After reading my last blogpost on Anonimatron, you must have asked yourself "Great, but how do I actually use Anonimatron to de-personalize my database"? I tried my best to make basic Anonimatron configuration as self-explanatory as possible, just start it without any command line arguments and it will tell …

In every software project, there comes a time where a bug pops up, nobody knows how to reproduce it, and somebody says "I know, let's test this against a copy of the production database".
