Popinator Fires Popcorn Into Your Mouth, Is Probably A PR Stunt

Popcorn Indiana, the same company that manufactures the bags of kettle corn you might find in a convenience store, posted a project on their website called The Popinator. It’s a device you fill with popcorn, turn on, and responds to the word, ‘pop’ by firing a piece of popcorn into your mouth. Details on this build are scant, most likely because The Popinator doesn’t operate exactly as described in the video demo for the Popinator project.

We’re going to call this build a figment of the imagination of one of Popcorn Indiana marketing drones, but the idea behind the project is actually fairly interesting. The idea of using voice recognition to determine when the word ‘pop’ is said to turn on the machine is very cool. Using time of flight to calculate where someone’s head is puts this build into a category of awesome we’ve rarely seen before.

Despite all that coolness, we can’t help but think this project is simply an attempt to “go viral” and get a ton of publicity from random tech blogs using only a video camera and a few hours in Final Cut Pro. You’re welcome, Popcorn Indiana.

Surely there will be a ton of comments for this post arguing the merits of this build. You can check out those comments after the break, along with the official Popinator video.

Some Technical Improvements On [Alton Brown’s] Hacked Smoker

September 17, 2012 by Mike Szczys 6 Comments

Bringing that smoky goodness to your cooking is neither hard, nor is it expensive. [Alton Brown], who we consider to be the MacGyver of cooking, always seems to be able to build cooking contraptions from common items. The smoker he built from a flower pot was the inspiration for [Tom’s] own project. But [Tom] added in PID hardware to smoke at just the right temperature.

The enclosure hides a single electric burner at the bottom. A metal tray full of wood chips sits on top of it, smoldering as the burner gets hot. You could just set it and forget it, but it will take a lot of trial and error to figure out which setting achieves the best results. [Tom’s] additional hardware, housed in the grey electrical box, switches the burner with a solid state relay. The PID controller takes measurements from a temperature sensor inserted in the lid of the smoker, ensuring perfectly prepared food every time.

If you’re interested in making your own you could try building a heating element from toaster oven parts.

R2D2 Drink Dispenser Will Happily Tinkle In Your Glass

August 16, 2012 by Mike Szczys 8 Comments

As with Jabba the Hutt we’d like to have our own service droid to serve up a cold one. We’re in luck; it looks like you can make your very own beverage dispensing droid if you don’t mind a little awkward dispensation.

The body started as one of those big protein drink mix containers. After spraying it white and masking off the entire thing with blue painter’s tape, the shapes for the blue designs were cut out and painted. Half of a foam sphere from the hobby shop was used to form the dome.

Liquids are dispensed by the pump system from a Super Soaker motorized water gun. You can see it fill up a beaker with a mysterious blue liquid in the video after the break. It’s a long way from challenging the Bar2D2, but it’s also something a mere mortal can build

Super Nincoffee Jr.

August 3, 2012 by Mike Szczys 10 Comments

Your morning routine doesn’t include enough old-school gaming. Break the caffeine habit and get your Mario on at the same time with the help of the Super Nincoffee Jr.

[Luigifreakout123] shares the details of the build in the video clip after the break. He starts by revealing that this is the second version he’s made. The first wasn’t a Jr., but instead used a full-sized Mr. Coffee unit. Neither make coffee, but instead serve as an enclosure for the gaming hardware. The on/off switch and original power cable are used to control the electricity to the console. Openings have been cut in the tops and front for a game cartridge and the two controller ports. A composite video and stereo audio cable comes out the back of the machine next to the power cord.

Yeah, it’s super simple, but sometimes that all it takes for a project to be a delight like this one is.

Building A Coffee Roaster From Junk

July 27, 2012 by Mike Szczys 10 Comments

[Rxdtxd] has tried his hand at roasting coffee beans in a frying pan. It works but he can only roast small batches at once. What he really needed was a large-scale roaster that would have no problem with a few pounds of the green beans all at once. He ended up building this large-scale coffee roaster out of junk parts.

The vessel which holds the beans is the drum from a top-loading washing machine. It was headed for the junk pile, but the fully-enclosed drum is perfect for this purpose. After acquiring it [Rxdtxd] set out welding a frame that would hold either side by the pivot points. He used a geared motor to automate the process. The output shaft on the gear box is meant to drive a chain, but he just welded some pieces onto the gear to use as a coupling.

In the picture above he’s giving the roaster a thorough testing with about ten pounds of beans. A portable gas stove placed below the rotating drum supplies the heat. After the beans have reached the desired darkness he pours them out into a large skillet to cool. Take a peek at the roasting action in the clip after the break.

Growerbot Turns Gardening Into A Science

July 23, 2012 by Brian Benchoff 18 Comments

A backyard vegetable garden can be a hit-or-miss game. You’re really not sure if your crops are getting enough sun, shade, or water until it’s time for harvest and you see the results of a season of hard work. Growerbot, a hardware project by [Luke] that’s up on Kickstarter now, hopes to change that. This box will pull down how much sun and water your crops should get, and is smart enough to correct any deficiencies.

On board the Growerbot is a soil moisture sensor, light, temperature, and humidity sensors, as well as WiFi connectivity and a few relays to run pumps and turn on grow lights. The idea is to learn from mistakes and achieve optimal growth for everything connected to the Growerbot. If you’re trying to grow some heirloom tomatoes in the midwest, you can go online and get the growth profile for your area and precisely control environmental variables for the perfect crop.

As of now, there are settings for in-ground gardens, raised beds, and hydroponic setups. There’s not much in the way of ideal growing conditions aside from what is available from the USDA, but once Growerbot is released we expect the data to start flowing in.

Any Flavor Sports Drink At The Push Of A Button

July 13, 2012 by Mike Szczys 22 Comments

[Sage Spate] wasn’t happy with the boring flavors of orange, blue, or red sports drinks. He decided to mix it up by building this flavor-mixing drink dispenser.

He modified the caps for each bottle to work with an air-pressure system. This way the bottles themselves serve as the reservoir and can easily be replaced when empty. Each cap has two openings, one is used by the dispenser nozzle and includes a hose that will reach all the way to the bottom of the bottle. The other hole connects to an air pump. Raising the pressure in the bottle forces sports drink up and out of the dispenser hose.

One air pump is used for all three reservoirs with a set of solenoids to enable each flavor individually. [Andreas] sent in the tip and mentioned that some of the parts are salvaged from an ink jet printer but we’re not sure which ones. At any rate, the next step in the project is to add Arduino control which will allow for custom mixing based on preset recipes.

We’ve embedded the demo video after the break.
