Tiny Devices

I experiment with various tiny devices, a.k.a. TinyPwners:

ScrewCamera - tiny camera embedded in a screw

OrangePi - a tinier tiny computer.

Widy - portable wireless router, good drop-box for penetration testing

Arduino - projects for Ardunio microcontrollers (morse code, LCD displays, wireless networks, Zigbee/XBee radios, etc.)

RaspberryPi - an extraordinary little device capable of running a full Linux OS. There are pages and pages of projects and notes here.

ESP8266 - minimal arduino-like chip device with full wireless networking stack, GPIO header pins, and not a whole lot else


Worksheets for teaching calculus and engineering concepts.


MSF - the metasploit framework

Metasploitable - A virtual machine with multiple built-in vulnerabilities, to learn how to use Metasploit

Linux Networking

Revisiting some basic networking configuration/setup for a project involving ad-hoc wireless networks.

Wifi Data Project

I mentored a group of undergraduate students on a Wi-Fi data project for Winter 2015-Spring 2016 at South Seattle College.


I've usually got some security projects going on.

Kali Linux

Lots of Kali linux related pages.


Building web bots, spiders, scrapers, etc. is a hobby of mine.

  • Bots - contains a summary of different bots that I've built. Mainly twitter bots, but some other bots as well.

Words Words Words

Scrapers are lots of fun. They basically automate interaction with the web, allowing you to programmatically visit pages, extract content, push buttons, submit forms, and so on.

Words Words Words is a scraper/bot that tags word etymologies in Gutenberg e-books. This project used a web scraper to look up word etymologies in an online dictionary, parse the results, and color-code the resulting word based on its root language.

Mainly for Raspberry Pi or other microcomputers, and for internet of things applications.
