Molson Canadian Smart Beer Fridges

Molson Canadian Smart Beer Fridges

 

Molson Canadian knows how to make an interesting Beer Fridge. While most would simply give the high tech illusion Molson Canadian has actually went to great lengths to allow the tech in the fridge to actually work the magic. In all cases the goal is to unlock the fridge to enjoy some cold beer. The methods to open the fridge has changed from version to version. There is one that looks for an inserted passport and opens the fridge when a Canadian passport has been inserted, one that opens when you sing a correct version of O-Canada and one that opens after 6 people say I am Canadian in 6 different languages. Nice thing is that Molson has made some behind the scenes videos that show us how the tech works behind the scenes. Of course all the tech could be tossed out if they went the simple route by having a remote human in the loop monitoring the interaction but it is nice that they stayed true to the concept in each case.

Ripples combines hardware and software to deliver any image of message onto lattes, cappuccinos, or any foam-topped drink. www.coffeeripples.com (PRNewsFoto/Steam CC)

 

If you are looking for an extra boost in the morning, how does a custom message just for you printed on your coffee sound? That is exactly what this 3D Printed Latte Art Machine does!

“The Ripple Maker employs 3D printing and inkjet technology to adorn the top of your hot beverage with complex designs that could take the form of someone’s name, their face, or even a personalized message to the attractive customer behind you. The machine itself is small, measuring just 8.5” by 10.5,” and connects via Wi-Fi to a library of designs. Users have the option to choose from a menu of themes and messages to stamp onto the milky foam canvas using natural coffee extract, also known as Ripple Pods.

Even suitable for the morning rush, the machine takes all of 10 seconds to produce a selected design on top of any cup up to 7″ high and 4.5″ wide. In addition, the Ripple Maker comes with a mobile app that enables baristas and companies to create custom designs, or upload and edit images straight from their smartphone camera roll. This makes sending a personal image as simple as devising a social media post.”

Nd YAG Laser Taken Apart

at 4:14 pm. Filed under Cool Gadgets, Insane Equipment

 

Photoinduction has taken apart his Nd YAG Laser. This is a complex beast of a system, I wonder what this thing cost new! He goes over some of the theory behind how the system works and demonstrates some of the parts from his huge laser system. There is some damage to this system, looks like there was probably a water cooling issue or just a loose electrical connection that allowed for some heat buildup.

Vinyl LP under an Electron Microscope

at 9:53 am. Filed under Complex Hacks, Insane Equipment

 

Have a look at the great video of this Vinyl LP under an Electron Microscope. Using an Electron Microscope isn’t as easy to use as a normal microscope, in this case the vinyl needed to be metal coated to be viewed. The scanned data was captured with a DSO and processed into a short video. It looks amazing, I didn’t realize how Vinyl Records LPs encoded the 2 stereo channels. The CD also looks very interesting up close.

Flamethrower Ukulele

Flamethrower Ukulele

 

Have a look at the Flamethrower Ukulele that  from Make built. Might not be the project that you want to use indoors or around anything flammable that you care about. But if you have a fire extinguisher by your side this sure would be fun to build, if you are an outdoor performer this would double as good crowd control. The system uses a modified calking gun to squeeze a small butane cylinder allowing the gas to flow down a hose to the end of the ukulele neck. A spark ignites the gas and starts the flaming fun.

Google’s Project Wing Delivery Drone Prototype

at 11:29 am. Filed under Complex Hacks, Cool Gadgets, Insane Equipment

 

Can’t wait till this style of delivery method is available. Tested had a first hand look at the Google Project Wing Delivery Drone Prototype. Not that it will have a direct replacement for things such as pizza delivery since the payload needs to currently be quite small but the flight and delivery method is great. Scaling these up to handle larger packages would make it great for package delivery directly into your secure back yard in minutes. I guess the only concern people will have is what happens when something goes wrong and it falls from the sky and knocks someone in the head.

Bug in Code Requires Boeing 787 Dreamliner to Reboot at least every 248 days to stay Flying

at 11:35 pm. Filed under Insane Equipment

 

The Dreamliner is a great looking plane and is full of the latest technology but like any other piece of sophisticated technology there is a lot of code behind the scenes keeping things working. Bug in Code Requires Boeing Dreamliner to Reboot at least every 248 days to stay Flying! If you have ever taken even an introductory programming class you will have probably seen the effect of integer math overflow. If you increment an integer one more time past the largest value it can hold it will overflow. This results in the new value being smaller than the previous value. This can result in strange scenarios that can cause issues if not checked for. There are many systems that had roll over issues 15 years ago (Y2K) when systems with 2 digit year representations reverted to the year 1900. Even the loved Unix time base is based on the number of seconds that have elapsed since January 1st 1970. This means that every day the Unix time increased by a count of 86400 since January 1st 1970. This also means that the 32 bit signed int will overflow in 2038.

I can understand how this type of bug got slipped into the plane code, I am just not sure how it remained uncaught. I would hope there would be very strict line by line code review where bound checks would have been tested. At least it was caught before it caused an accident and it will now be a reminder how important every bit of code it. At least if there is an issue in the air with the backdoor a skilled hacker might be able to hack into the system and bring things back online. :)
