Extracting a 3D Model from drawings
Perspective techniques to extract a 3D model from a painting, nice! -
Constructing 3D models of buildings is all about extracting the geometry from images using photogrammetric techniques. As such, although it goes against basic geometric principles it also lends itself to historic reconstruction via referenced hand drawn images.Digital Urban: Extracting a 3D Model From Drawings - SketchUp - [via] Link.Over eight years ago we used the now sadly demised software CANOMA to create a view of London in 1616 - as the YouTube movie illustrates. CANOMA excelled at such scenes as it required only a single image to define the 3D space compared with many photogrammetric packages which require matching views and overlapping construction points.

Dirty Don's Margarita maker
SCA Scot writes -
Sara's uncle Don is a bit of a tinkerer. So, when you've got a small-block 400, a trailer, assorted parts and the ability to custom fabricate a 6-inch tall replica of a blender blade out of stainless steel, what do you do with your spare time?Dirty Don's Margarita Maker - [via] Link.Make the world's fastest margarita machine.
Add: 6 bags of ice, and 18 bottles of ready-to-drink margarita mix. Turn ignition, and rev engine for 10 to 20 seconds. Open valve and enjoy.

HOW TO - Make bacon soap
Goooooood morning Makers, it's time to make soap... from bacon, with the latest episode of New Know How -
Soap can be made from just about any kind of fat. Even though fat from bacon, called lard, isn't the finest of fats to use for making soap, it somehow seemed to be the most exciting. Why? Because bacon is amazing. It has an almost mystical power to it and is a food that can be craved to almost no end. I figured what better way use the extra grease I had from cooking bacon then to turn it into soap!instructables : How to Make Bacon Soap - Link.

Google solar panel project
This is neat, the Google solar panel project shows much much power they've slurped from the Sun and the equivalent kilowatt-hours...
In the last 24 hours, Google produced 9,900 kilowatt-hours of electricity from the sun.Google Solar Panel Project - Link.In October 2006, Google announced a commitment to solar energy production and launched the largest solar panel installation to date on a corporate campus in the United States. Google has installed over 90% of the 9,212 solar panels that comprise the 1,600 kilowatt project. Panels cover the rooftops of eight buildings and two newly constructed solar carports at the Googleplex (check out this SketchUp fly-over video).
This installation is projected to produce enough electricity for approximately 1,000 California homes or 30% of Google's peak electricity demand in our solar powered buildings at our Mountain View, CA headquarters.
We built this page to monitor and share the day to day production of clean, renewable energy from our very own rooftops.

Coin rings - how were these made?
Ed writes -
Phil, For years I have been making coin rings using the traditional method of tapping the rim of a coin until it's flat, drilling out the center, filing etc.. Recently I came across some coin rings that appear to be made using an alternate method and possibly specialized equipment. I've searched the web and I haven't been able to find any info on technique or tools used to make these rings. Could you please ask the readers of Makezine blog if they have any knowledge of how these are made and what tools might have been used to make them.Post up suggestions and more in the comments!

MakeShift 09: Analysis, commentary, and winners
Lee D. Zlotoff (creator of MacGyver) has the MakeShift 09 analysis, commentary, and winners -
This was perhaps one of the trickiest challenges yet, with lots of possible solutions for how to establish communication with the outside world when confined in a school lockdown. And, despite the eerie coincidence of the tragic events at Virginia Tech, you all responded with an amazing display of MAKE ingenuity, proposing everything from semaphore flags to Yagi antennas to trying to produce homemade insulin for the stranded diabetic in the class! Wow.makezine.com: MakeShift 09: Analysis, Commentary, and Winners - Link.Some of you seemed to think the challenge was a no-brainer and that a computer with wireless internet capability would easily find an open network and solve the problem. But most of you realized it was a bit more complicated than that, and a range of options from low- to high-tech might have to be tried to ensure a decent chance of success. Now, while trying to signal using Morse code and semaphore flags may look good on paper, the fact is almost no one in the general public knows them anymore so they probably wouldn't get you very far. What's more, they only provide a one-way communication, which isn't really the optimum solution to the situation. But other low-tech forms of attracting attention--reflectors, bright signage, controlled signal fires--might still be worth a shot and at least alert someone enough to know there was a problem.
But what we were really thinking about--and hoping for--was how you might tweak or expand on the technology at your disposal to effectively establish a useful two-way connection. And here again many of you rose to the challenge with flying colors, proposing a slew of easily built antennas to boost the range of the computer, cell phone, or even the walkie-talkie--some of which we were convinced stood a very good chance of working. Plus some of you went the extra distance to consider the human dynamics of the situation by suggesting the class break into teams, each to work on a different potential solution. This approach not only increased your odds for success but also got the maximum number of people involved to keep the class focused on the project and diminish the likelihood of panic that can often accompany--and exacerbate--such situations.
Some of you really impressed the more technologically savvy among us, who want you on their team if they're ever locked down somewhere. Others went outside the technological box and came up with some straight and to-the-point nontechnological approaches (e.g., posting a "NEED INSULIN" sign in the window). While we hope none of you ever needs to exercise any of the approaches you considered, it's probably a terrific way to keep ourselves prepared by imagining how we would escape or improve a tough situation should we ever find ourselves or our friends in one.
So kudos to everyone for rolling up their sleeves and thinking hard about a way to overcome a situation we'd all rather not think about. But stretching our minds to really make the most of our techno-toys in a crisis has--and no doubt will--save lives in our increasingly unpredictable world. And that alone makes it worth the effort, no?
The winners of the MakeShift Volume 09 Challenge are:
- MakeShift Master--Plausible: David Glass - Link.
- MakeShift Master--Creative: Jonathan Deber & Karen Dawson - Link.

TNT, Round 19: Power Rangers
Our latest TNT (Tips-n-tools) is up, check it out, sign up and read more from Arwen -
If you haven't felt the first whiff of summer approaching (although I must admit that here in San Francisco it's hard to imagine), get up from your workbench and step outside. This round of TNT reviews is all about power, whether it's saving it or finding creative ways to use it.makezine.com: TNT, Round 19: Power Rangers - Link & sign up.I've been hearing more and more about power consumption, and the gadgets that are being created to track it and reduce it. While a part of me fears that these will just be added to the huge piles of unnecessary junk in everyone's drawers, if they can truly help you be more efficient, I'm all for it. Below, I point to two recent blog posts on just this topic, as well as to another blog that's all about power consumption. There are also a few tips and tools to help you save time: a tool that won't have you in knots trying to tighten ropes, an easy reuse project creating a light box for photographing your latest projects, a pre-fab workbench that really works to help keep you organized, and then few tools to make the most of your BBQ. Thanks to the TNT readers who sent in reviews! So get ready for a cool (or is it hot?) summer.

HOW TO - Make a one transistor super-regenerative FM receiver
.jpg)
Good project made with RadiShack parts...
This radio is sensitive enough to tune 20 stations across the FM band, some with volume high enough to drive a small PM speaker. The ability to tune 88.9 MHz and 89.1 MHz is testimony of its selectivity. The signal-to noise ratio rivals that of the better walkman type radios.Introducing the Radio Shack Special Project... - Link.

Recover files from a flash memory card
Chris writes -
Phil - The other day my sd card failed on my digital camera. After buying a new camera and card to replace my beater and the dead card, I decided to try to recover about three weeks of pictures from the card. After a little searching I found this great utility from cgsecurity.org It is a free, open source, file recovery application for flash memory. First it recovered all the files from my card. When I verified that they were saved onto the hard drive, the next day I used the utility to repair the FAT boot sector. I am so psyched that I recovered the files, and now I have a spare 2 gig card after replacing it with a 4 gig SD. I would definitely use this software again. I will try to remember to offload from the card more often....Main Page - CGSecurity - Link.

C64 USB keyboard
symlink.dk writes -
This page describes how to build a USB-keyboard in the form-factor of an old C64 breadbox. Actually, with little modification it can be used for any kind of keyboard, since the source code is available, and all that needs to be done is to modify the key-to-scancode mapping.SYMLINK.DK - Electronics - Link.The c64key is based on Objective Development's AVR-USB firmware only USB stack for Atmel AVR microcontrollers, and the simple HIDkeys example they provide. The implementation presented here has a more elaborate keyboard scanning routine, and allows multiple keys to be pressed (and detected) simlutaneously.

Turbine engine go-kart
Wow - Here's a rad turbine engine go-kart on eBay -
This kart is the result of several thousands of pounds and many, many man hours of work and was designed, constructed and operated by a qualified aircraft engineer. Fitted with a MILITARY spec JFS-100 jet engine normally used as a jet fuel starter for the US Navy A7 corsair carrier aircraft. Additionally, and possibly uniquely, it is fitted with a superb AFTERBURNER unit creating extra thrust, noise and spectacular fire and smoke effects. Perfect for shows! Push one button to inject fuel, then push the other to ignite!eBay - [via] Link.

Doublet amplifier
Octopart's hardware blog has a dual channel music player amp (in an Altoids tin, of course)...
Have you ever seen a couple sharing a single pair of ipod buds, each listening with only one ear? That was the problem I wanted to solve when I started building dual channel headphone amplifiers while I was back in grad school. After a long day of soldering krytrons and high voltage capacitors in the plasma physics lab I would come home and...solder some more.Octopart - Link.
