Some items are groups; click in the descriptions to expand.
CCCP
Cargobike Community Canvassing Project: It's definitely not an (NGP) VAN, but it might be able to accomplish some similar tasks with a bit of extra effort.
AtmosNode
Includes atmospheric monitoring sensors (VoCs, CO2, Temperature, Pressure, Humidity), passive IR, motion detecting camera, and a large speaker and amplifier
DoorSensor
Ultrasonic distance and circuit sensor to monitor a doorway; based on an Adafruit M0 Feather Wifi (An Arduino-compatible SAMD board)
FlatNode
Includes speakers and amplifier, a camera for motion sensing, and a USB microphone for audio sensing
PresenceToken
A basic wifi beacon based on an Adafruit M0 Feather with Wifi (An Arduino-compatible SAMD board)
JarLampSystem
A series of devices using a common "lamp" module created by mounting a high power RGB LED in the lid of a plastic Ovaltine jar.
Handheld
A handheld, high power, seven color LED lamp compatible with my jar lamp system. Uses a 5V USB power bank routing through a small board with three switches (to control the three colors) plus a low value, high power resistor (to reduce current, as the lamps were designed for 3.3V not 5V.) No schmatics or build details -- if you have the skills to build this, you know how, it's three switches, a resistor, some protoboard and a cardboard box.
Tower
Mounts to hold an RGB jar lamp on a quarter inch threaded rod; controlled by a Raspberry Pi through a Sparkfun SX1509 I/O expander board. Colors are used to display the current status of various servers and sensors.
OilDiffusers
Various attempts to create devices to automate diffusion of essential oils
AutoMister
An automated oil diffuser based on modified AirWick brand Essential Mist diffusers. Connects to my main security/automation network, o it triggers based on timing and presence.
FanHook
A small hook designed to clip onto an 80mm blower style PC fan and hold a bottle of essential oils, so the fan will draw air past the open bottle and into the air. Works well, but extremely noisy.
FanStand
A very simple stand designed to hold a 40mm fan over a typical 10ml essential oil bottle. Works best if you add a small shroud of tape or paper around the top of the stand so all of the air is drawn up past the bottle.
SCADModels
OpenSCAD files for assorted 3D models
Organization
3D models of various organizational tools. Designed for the cheapest possible printers (I have a Monoprice MP Mini)
firewall-lists-3
A shell script for generating IP blocklists using nslookup across various DNS servers based on a list of hostnames
tutorials
Mostly these are so I remember how I set all of this up. They may not be up to date or complete.
servers
Basic infrastructure setup
webdesktop-source
Old instruction for creating a compatibility tool for running old VB6 apps through a cloud desktop
userspace
My user scripts -- .emacs, conkyrc, backup scripts, etc
conky
Layout used by my Conky desktop scripts. Mail counts in Conky don't actually work right now, they need a Thunderbird plugin that's no longer supported. I have a fix for that...I just haven't implemented it yet. The rest of it should work fine though.
emacs
You probably don't want to actually use this .emacs file...
rsync
My nightly backup script. This one is actually halfway decent!
