I loved this device but reader John Rusnak, along with a couple of other folks, wrote to ask, "Why would I spend $149 on a 'print server,' when I can buy an AirPrint supported printer for $99? I just use PrintCentral (an app costing only $7) that lets me print to any Wi-Fi printer, not just AirPrint supported ones!"
Ah, what if you already have a pricey laser printer? Are you going to junk your $600 color laser printer? Or what if you have several printers?
As for the PrintCentral app published by EuroSmartz, it's an OK piece of software, but if you're trying to print from, say, Apple's Pages word processing application, then PrintCentral won't help you ... you can only print from the PrintCentral app.
Sure, with PrintCentral you can print Web pages, but again, that's only from the browser provided by PrintCentral, not from Safari or from my favorite, the Grazing browser. Plus, PrintCentral is geeky and complicated in a "kitchen sink" kind of way, making it a poor choice for naïve users.
Nope, unless you are a green field site or have no desire to keep your existing printers, then the Lantronix xPrintServer is the best solution for AirPrint enabling printers I've found.
Now on to today's topic ...
Do you have a really good idea that you're trying to get off the ground? Great! But what if you have a small problem such as, oh, say, a lack of startup capital? The answer may well be an online service called Kickstarter.
Kickstarter is a brilliant idea. On the Kickstarter site you can pitch an idea for a project and ask for donations. The compensation for those who chip in might, depending on the size of their pledge, be a T-shirt, a poster, or some other acknowledgement of their involvement or, if an actual product is involved, the pledge might be actually preordering the product.
Take, for example, this tech project called Twine floated by a startup called SuperMechanical, which prompted me to discuss Kickstarter. Although Twine is now closed, the interest in the project was incredible: The original goal was $35,000. In the end some 3,966 backers pledged a total of $556,541 by the deadline of Jan. 3, 2012!

I think it would be fair to say this pitch was successful.
The reason for its success is that Twine is a really good idea that appeals to lots of geeks and solves the problem of simply and cheaply monitoring environmental and physical conditions.
The Twine system is based on a low-power wireless module with both internal and external sensors that can connect to a Wi-Fi network and thence to the Internet. The project explains that "Twine is the simplest possible way to get the objects in your life texting, tweeting or emailing. A durable 2.5 [inch] square provides WiFi connectivity, internal [temperature and acceleration] and external sensors, and two AAA batteries that keep it running for months [power can also be supplied via a micro USB port]." The developers also say that "Twine will email you when you need to change the batteries."
Configuration, management and sensor data communication all occur in "the cloud" and "[a] simple web app [SuperMechanical's Web-based Spool service] allows to you quickly set up your Twine with human-friendly rules -- no programming needed. And if you're more adventurous, you can connect your own sensors and use HTTP to have Twine send data to your own app."
So, let's say you want to know when a piece of equipment overheats. You might be able to simply drop a Twine unit into the equipment's casing or, if that's not an option, add an external temperature sensor and attach the Twine to the outside of whatever it is. You'd then set up the Twine unit to work with your Wi-Fi system, go to the Spool service, and configure the Twine unit to send you a message via texting, Twitter, email or a custom HTTP request (for example, a request to update a Web-interfaced database).
In operation Twine devices simply send sensor status updates to Spool service. The Spool service implements the rules that determine how sensor changes will be handled and trigger whatever actions are required.
The compelling advantage of Twine devices is that they are simple and cheap to setup and manage, especially compared to, say, something like building a custom Arduino system.
You can order a Twine today for delivery in May for $99. With a breakout board for adding your own custom sensors it's $119, $134 with a moisture sensor or a magnetic switch sensor or $174 with both sensors. There's already an enthusiastic and active user community and popular demand has prompted SuperMechanical to commit to developing an electrical current sensor for the Twine which they plan to sell for $45.
As cool as the Twine is, which is very cool indeed (and worthy of a provisional Gearhead rating of 5 out of 5 ... I have yet to play, er, test one), it's Kickstarter's amazing ability to crowdsource funding for projects that really impresses me.
If you're looking to jump-start your cool idea Kickstarter is the place to not only test whether people care but to find out if they care enough to fund you.
