Over the past few weeks I have been experimenting with receiving data from satellites.

I recently bought two used HP enterprise SSDs for VM storage on Proxmox.

Today I wanted to make a web service internet facing without exposing the origin server.

After months of searching I managed to purchase a used Chamsys PC Wing from eBay at a good price.

Yesterday Félix Aimé posted on X (formerly known as Twitter) a neat YARA rule to detect PDF documents.

Google recently announced the release of Magika, an “AI-powered file-type identification system”.

Today I released a new tool named rtfsig. rtfsig is a simple Python utility that helps create signatures for malicious RTF documents.

I have updated my GPG key, revoking ID 0x35076cbaa663a704 and replacing it with 0x57974c5b48a00d9b (find it on keyservers).

This is a local mirror of a blog written by me and originally published by NCC Group.

In a waiting room this week I opened a newspaper to find the following puzzle, named “Suko” (a trademark of Puzzler).

During the recent site cleanup I decided to disable comments and remove (most) previous comments from the site.

I’ve given this site a long overdue tidy, finally moving away from Wordpress to a static site.

This post is entirely based on my opinions.

Banks and financial institutions are constantly giving out advice about email safety, helping customers to avoid phishing scams.

In short: SiteWizard are dirty annoying spammers who try random email addresses to send their silly SEO spam.

A quick note for anybody using libnids on a 64-bit machine (AMD64), you will need to compile with -fno-strict-aliasing if you use optimisation at -O2 or above.

I have recently started to use Proteus ARES for PCB layout.

Today I wanted to quickly calculate a truth table for a simple boolean equation.

Today I removed clamav from my VPS, which was built into the mail service I run.

Today two sets of PCBs arrived from OSH Park.

I wrote previously that I would review a graphic LCD made by dogm, which was provided by the company so I could update my ST7565 library.

The Apache vhost configuration snippet below will force any non-SSL requests for a website to be rewritten to an HTTPS site instead.

This page documents a hobbyist kart timing system that I developed last year (2012).

I have written a simple tutorial explaining how to use the PIC fixed voltage reference (FVR) in order to calculate Vdd, using no external components.

Microchip’s Application Note AN1333 hints at a useful technique for measuring the Vdd of a PIC using only the internal Fixed Voltage Reference (FVR) module.

People often ask how I assemble SMD boards, the video below is sped up to 20x and demonstrates the process.

Even more bugs that should have died in 2005..!

After some recent discussions with two friends Rich & Dave I have been playing with WebSDR, decoding all sorts of transmissions using MultiPSK.

Another new year, another bug from the past.

Today I received some prototyping boards from Mike at White Wing Logic.

I was surprised today to receive an email about a bug.

This wasn’t the first PCB I produced but I had to start numbering somewhere..

One thing I like about some blogs is that you can easily see when the admin has replied to comments.

I have made a few changes to my ST7565 library, available from GitHub.

I needed a sine wave carrier for a magnetic transponder system I am working on.

I am currently trying to document the various electronics I have done previously.

This is a very simple PCB based on the LM317 voltage regulator.

This page covers the theory of using a graphic LCD based on the ST7565 controller.

I made this simple little board so I could use the popular Hope RFM12 with a breadboard.

I have updated the template for this site to use the Responsive theme from ThemeID.
