Baking SMT - toaster oven surface mount component soldering
Wagner writes -
Baking SMT on a cheap kitchen toaster oven is not difficult. You just need some patience and exploration good will. In this page you will read the manual procedure to bake SMD boards into a regular kitchen toaster oven appliance. Follows information about how I produced an automated solution.Baking SMT - toaster oven surface mount component soldering - Link.Each toaster oven react in a different way, each one, cheap as it is, will produce a different temperature heating and cooling profile curve.
Soldering SMT components to a PCB requires "some" temperature profile, that is, certain temperature for certain time, then other temperature for other time, and so on. This is NOT so much critical, as I experienced. The soldering process happens in one way or another when the everything reaches around 450°F, but critical is the sake of the components on board. Some components can crack immediately if the temperature goes up or down very fast, others don't show any damage immediately, but they will fail in a month or two (capacitors for example).

Austin Summerfest 2007
David writes -
We attended the Austin Summerfest ham meet up. I took along my limited digital camera to capture some shots. The quality is so-so but I hope you get the general idea. Ham fest events are great for the electronic hobbyist. The Ham’s bring large collections of components and test equipment to sell or swap. You can stock up your home lab without spending too much. The first picture shows the inside of the swap area.Austin Summerfest 2007 - Link.

Sputnixie - nixie clock
Greg writes -
This site provides a complete design for a nixie tube clock. In this site you will find the schematic, layout, source code, specifications, bill of materials and an enclosure example for my clock design. I have worked on my nixie tube clock design for more than 2 years. The material provided is my design and is thus copyright; I provide it with the intention of sharing my enthusiasm and enjoyment of designing and building a nixie tube clock.sputnixie.com - Link.
(Update, not open sourced - still cool).

Open source hardware kit project donates $500 to the EFF
Remember that open source hardware "Digg button"? It's a simple kit to teach soldering and basic electronics (I co-developed it with Adafruit and Digg)... and part of the goal was to donate proceeds to the EFF, the first $500 was just sent off, this might be the first time an open source hardware project sent money to someone! - Link.

Flashlight beams make music on photo-electric marimba
Modern Mechanix 1935
MODERN electronic engineers duplicate the music of a primitive marimba band with light beams, photo-electric cells and radio tubes. Dr. Phillips Thomas of the Westinghouse Research laboratory recently demonstrated a "light music" instrument which played by waving flashlights held in each hand.Dozens of photo-cells and radio tubes are lined up side by side atop the new musical device. For each musical note there is an oscillating circuit which produces electrical vibrations when light is directed on that circuits photo-cell. Reproducers convert the electrical vibrations into sound which is directed into the marimba pipes.

MAKE vs BUY - Nixie clock kit vs LED "tube" clock
For $200 you can buy the Tubes Clock by B&W, they're selling LCDs inside little tubes for the nixie effect or you can buy your own *real* nixie tube clock kits for $150 or less and learn about building electronics. Here are a few of the kit makers to check out...

Capacitive touch pad update
Gordon has posted new info and pics on justDIY for his capacitive touch pad project. Happy with the results of the prototype, he sent off the PCB design for fabbing. He added a 2x8 header to the board, for use with a ribbon cable. He also increased the values on the caps, settling on polyester film 220 nF (double what he used on the prototype).
