Yesterday’s Gmail service outage is a hot topic on just about every news site right now. For so many of us that have always taken the reliability of Gmail for granted it was a real shock to lose all of the functionality of the web based system. Now that we’ve learned our lesson, here’s a couple of tips to help you out the next time there’s an outage.

[woody1189] put together some automatic lighting for his closet. Nine LEDs are grouped into three lamps and controlled by a hall effect sensor. He prototyped this on an Arduino and then migrated over to an ATtiny85. Although the current implementation could be accomplished without a microcontroller, we’d love to see some firmware improvements such as an auto shutoff for when you forget to close the closet door. The hall effect sensor seems to pop up in a lot of projects so make sure you get a few of them with your next parts order. Video of this in action after the break.
National Geographic has pegged September 2, 2009 as the 40th anniversary of the Internet. They do not cite their source and our source doesn’t make the same claim. But, August 30, 1969 is the date the first Interface Message Processor was delivered to the Arpanet. The IMP is what allowed different computer networks to talk to each other and so it follows that September 2 is probably an acceptable date to celebrate.
To commemorate this glorious day we’re sharing some of our favorite History of the Internet videos. Start with the National Geographic video and then take in the geeky, the new, the old, and the simple. Continue reading “Happy Birthday Internet: 5 History Videos”
BrewTroller is an open source brewing control system based on the Sanguino. Targeting home beer brewers, this project gathers some of the best features from other DIY brewing controllers and packages them into a hardware and software setup so it’s accessible to those without the skills to design their own. It can interface with 4 heat controllers, 32 pumps/valves, 6 temperature sensors, 3 volume sensors, and 1 steam pressure sensor. The system displays information through a 4 line LCD. It can be used to monitor and maintain temperature during mashing, boiling, and chilling. If you have a more advanced setup that involves automatic valves, it can control those for you with almost limitless reconfigurability through every step of the brewing process.
We thought it was pretty hard core that at least some of the kits shipped with hand made PCBs. At the very least, it shows that it is possible to make this board yourself with the provided PCB layout.

The alpha version of Lubuntu 9.10 Karmic Koala is now publicly availabile. The project brings together Ubuntu and LXDE, the Lightweight X11 Desktop Environment. This combination makes for a lighter version of the most popular Linux distribution. Both Xubuntu (which utilizes the Xfce desktop) and Lubuntu are meant to run well on lower resource computers such as netbooks. With the ISO smaller than 400mb and using quite a bit less system resources Lubuntu looks promising.
Right now it looks like the original backup ISO link is down. If you can’t wait, try this torrent.

We’ve always felt that hard drive manufacturers were dirty crooks because of their use of fake math to make drives sound bigger than they actually are. Here’s a quick refresher for those who need it: Because digital information consists of 1’s and 0’s (two possible settings), digital architecture revolves around powers of 2. Long ago, when nomenclature was setup for measuring data the term kilobyte was adopted to represent 2 to the 10th power bytes (base 2, aka real math). The problem here is that 2^10= 1024 and when laymen hear the root “kilo” they think 1000 which is 24 byes less (base 10, aka fake math). So, if you have a 500,000,000 byte drive, base 10 math would call that a 500GB drive, but base 2 math would call that 476.8GB.
We understand why hard drive manufacturers use the base 10 system; larger sounding drives sell better. Now we find out that OSX 10.6 Snow Leopard is using base 10 math to calculate storage space. While base 2 math is the standard storage measurement for operating systems it may at first be difficult to understand why Apple would change to a base 10 system. But think about it once more, doesn’t Apple have a lot to gain if all the storage-containing-hardware they sell sounds bigger than it actually is?

[Carlos] sent us his project that uses an Arduino as a pH meter. In order to sense the acidity or alkalinity of a solution, a glass electrode is connected to the ADC of the Arduino through a fairly complicated calibration, amplification, and filtering circuit. Admittedly, it may not be cheaper or as accurate as some commercial models, but it is an open project and can be interfaced with a computer via USB.
