A Raspberry Pi controlled mini CNC Laser engraver [keep updating]
I recently made a mini CNC laser engraver using two DVD drives salvaged from old computers and <$10 extra parts bought on eBay. The controller of the CNC machine is a Raspberry Pi, a $35 credit card size computer. The engraver turns out to be pretty successful. So I am sharing it with everyone.

Raspberry Pi – Stabiler 24/7 Dauerbetrieb › Datenreise
Die Leistung des Raspberry Pi ist für viele Serveraufgaben vollkommen ausreichend. Aufgrund des minimalen Stromverbauchs von ca. 3,5W liegt es daher nahe den Minirechner im 24/7 Dauerbetrieb einzusetzen. Für einen stabilen Dauerbetrieb müssen jedoch gewisse Punkte beachtet werden.
MQTT
IEEE 802.15.4
The IEEE 802.15 TG4 was chartered to investigate a low data rate solution with multi-month to multi-year battery life and very low complexity. It is operating in an unlicensed, international frequency band. Potential applications are sensors, interactive toys, smart badges, remote controls, and home automation.
Camera Module Lens Modifcation - SingletonMillerWiki
The purpose of this project is to replace the stock lens assembly of the Raspberry Pi Camera Module with a larger lens. The aim is to increase the be able to fit other lenses and filters in order to modify the field of view and waveband of operation. Overview

Raspberry Pi webcam
*** UPDATE NOTE: I am now using Motion instead of ffserver see this new post: Battery powered, Wireless, Motion detecting Raspberry Pi *** Here's a walk-through of the steps I took to get a webcam stream on the Internet from my Raspberry Pi. Equipment: Raspberry Pi 8G class 4 Sandisk SD card 5V 1A MicroUSB power supply Ethernet cable HDMI cable USB keyboard Webcam (PS3 EyeToy) Prepare the OS Arch Linux ARM - you can get the image file from the Raspberry Pi download page. Write the image to the SD card. (I use Win32DiskImager) Expand the main partition to fill the SD card.
