RFIDIOt.org - RFID IO tools
Adam writes -
RFIDIOt is an open source python library for exploring RFID devices. It's called "RFIDIOt" for two reasons:
- I like puns. This one stands for "RFID IO tools"
- Since I haven't done any serious programming for a long time, I felt like an idiot having to learn a whole new language and the code probably looks like it's written by an idiot. However, python rocks, so it was worth it!
What does it do?RFIDIOt.org - RFID IO tools - Link.
It currently drives a range of RFID readers made by ACG, called the HF Dual ISO and HF Multi ISO, which are both 13.56MHz devices, and the LF MultiTag which is 125/134.2kHz. Frosch Hitag reader/writers are also now supported. There's no reason it couldn't work with others, these are just the first ones I got my hands on, and since they present themselves to the O/S as standard serial devices without having to install any drivers, it made interfacing very simple (but see the Technical Note section below as I've had some issues recently). I have written some example programs to read/write tags and have started on the library routines to handle the data structures of specific tags like MIFARE®. It is far from complete but I thought I'd follow the "publish early, publish often" philosophy on this one...PC/SC (MUSCLE) devices, such as the Omnikey CardMan are also supported. I am curently testing with a CardMan 5321.

The Bender brewer project
Simon writes -
This is my project to build a life sized, beer brewing, remote controlled talking Bender robot from Futurama. He isn't quite finished so no beer has yet been brewed in him yet but he is getting there. The body and head are mostly done and his MOS 6502 processor based brain/voice is complete and working. I am updating my progress as I go.The Bender Brewer Project - Link.

HOW TO - Make bacon
Dave sent in this great how to on making bacon, he writes -
I'm starting to gather a reputation as a fairly self-sufficient guy. Of course there's the homebrewing, the woodworking, the gardening, and yes, we're thinking of getting some chickens. So I was not really surprised when my sisters got me a book on home meat-curing for my birthday, the simply, yet fancily-named Charcuterie. Beyond its appeal as a potential source of deliciousness, the book is stuffed full of great pencil drawings of one of my favorite subjects: meat preparation. Sausage, Prosciutto, Jamon Serrano, Saucisson Sec, and that staple of every Iowan's diet, sweet, sweet bacon. Home-made bacon. Made ... at home. By you. Holy. F-ing. Shit.HOW TO - Make bacon - Link.Perhaps home-made bacon's greatest appeal to me was the possibility of slicing it to whatever thickness my heart desires. Actually, my heart desires me not to cut bacon that thick. But my stomach will really be into it. Speaking of stomachs, home-made bacon offered me another once-in-a-short-lifetime opportunity: the chance to speculate on pork bellies.

Rubber-band sharpshooter
Popular Science 1946 -
How a North Carolina Sportsman Makes and Shoots His Slingshots. ONE OF boyhood's traditional toys has come of age. Jim Gasque, North Carolina sportsman, has proved that the ordinary slingshot, when properly made and used, can be an adult weapon of deadly accuracy at distances up to 30′--a range sufficient for stalking small game. He shoots regular No. 0 buckshot.Modern Mechanix » Rubber-Band Sharpshooter - Link.His slingshots are made as shown, the dogwood forks being dried in a slow oven overnight after tying. Instead of inner-tube strips, he uses two rubber bands 1/16″ thick, 5/8″ wide, and 7-1/2″or 8″ long.
When shooting, he takes a stance similar to that in archery, body at right angles to the target, feet apart, and weight balanced on both feet. Holding the shot cup at the right eye, he stretches the rubber by extending his left arm fully while aligning the target in the sights -Tom Cushing.

Touch box
Craig writes -
Recently I have been exploring Physical Computing. I have always preferred learning new subjects by developing self-defined projects that use the topics, skills or components I want to understand. Here is my latest project that is helping me understand digital electronics.Touch Box - Link.This whatchamacallit uses an Arduino NG for the microcontroller and an LED Red/Green/Blue Serial Matrix from Spark Fun for the display. When left on its own the display randomly displays patterns and alphanumeric characters that dissolve by way of some random shenanigans. It also picks colors randomly from a set that I have deemed aesthetically pleasing. My first computer was an Atari 400 (1979). Its system font used an 8 X 8 matrix which just fits the RGB LED matrix. So for old-times-sake I found the font on the internet, and with a little massaging in Photoshop and Actionscript, encoded it in a form I could transfer to the Arduino for use on the LED Matrix display.
I like the fork.

HOW TO - Make a Moleskine-like notebook
Here's another decent how to on rolling your own custom notebooks. By the time you're finished, you certainly won't save any money having made it yourself (if your time counts for anything), but bookbinding can be its own reward. And creating your own notebooks means you have total control over cover and internal designs, materials used, notebook sizes, etc.

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).
