Arduino as a Clock Source
Quite some time ago, I built a Ben Eater 6502 computer. It was fun but frankly I’m too nervous to do anything cool with it but follow his tutorials. I wanted to take the clock circuit and order a PCB and 3d print a case that allowed me to switch from stepping, astable, bistable, and…

Powering Up Christmas: A Creeper Clock Makeover
If you aren’t comfortable around electricity, don’t attempt this. Consult a professional. Make sure nothing is plugged in. Doing this may impact the warranty of the device or prevent the resale of the device. It feels like the plethora of garbage you can buy on Amazon is just designed to sell more USB power bricks…

3D Printing a Microphone
A few weeks back, a friend was over for some prison wine. We decided we’d karaoke and have a good time, but I was having an issue finding a microphone. I had casually remarked “Well, I’ll just go 3d Print one”, and he said “There’s no way, right?” and I replied “Of course not!” Challenge…

Wordfence and a Secure wp-admin
I use WordFence to protect my site from attacks, many years ago I helped a Redditor secure his site (maybe I’ll blog about it one day). He was using WordFence and it found a nasty local file. I’ve enjoyed it enough to where I spoke about it at a security conference a few years ago.…

Using AI to Secure Legacy Software
In 2006, I made the decision to stop writing software for Windows (as much as I did at the time), and move to building web applications. The idea was that, unlike desktop applications where I don’t see my users and can’t do updates easily, in a web app I can. I spoke with my brother,…

The Saga of Aldi Pruno
This is part two, for the recipe and story, check out this blog. Update: My Friend from the Midwest tried it, said 2.5 out of 5! It’s been several weeks since I made the Aldi Pruno (Prison Wine) — I followed some best practices, such as a proper airlock and sanitation procedures, aerating the wine,…

Prison Wine: Why Some Laws are Dumb
It’s August here in Texas, and I decided to write a blog that shouldn’t come out for another few months. I wanted this to come out around a significant date for prohibition, but I don’t have the patience. I got to reckoning with an old Midwestern pal about some good ol’ moonshinin’. The story started…

Impersonating a Police Officer
I don’t normally admit to felonies online, it generally is ill advised and troublesome. So of course, I’m still not going to. Some time ago, I wrote about how I occasionally go for late night walks. Sometimes it is to be healthy, other times it is to run to the store and not drive. One…

Unmasking Sneaky Microcontroller Part 1: Reverse Engineering the Board
Several years ago, I had added accessory lighting to my tractor since I used it to pull a trailer of stuff around my property and to plow a 200′ long driveway after work. Since after work is usually after 5pm, and during winter it’s dark, I wanted to be seen by all of the meth…

I Messed Up…
Just yesterday, I posted a blog about spying on chip communications. In there, I included a little tidbit that I “deep fried” here. Now, I thought that it was obvious that I was trying to be sarcastic, but today I get an email from my domain registrar telling me that one of my domains has…

Spying on Chip Communications with Arduino
Recently, I had posted about the faceplate of a safe I had found, got to work, and talked about a method of breaching it. I decided to go a bit further and dump the EEPROM, but the contents of it have (so far) meant nothing to me. I decided it was time to see what…
