3D Printed Latte Art

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.”

Computer Printer made from a Typewriter

Computer Printer made from a Typewriter

 

Chris Gregg made a an interesting Computer Printer made from a Typewriter, the typewriter is an old mechanical style and there is a bunch of electronics and solenoids attached to make the magic happen. The solenoids press the appropriate keys to type on the keyboard. One issue is that a microcontroller with enough outputs to drive this number of solenoids is not that common in the DIY space. Chris developed a custom shift register circuit that allows him to easily control all of the solenoids with just a few IO pins.

Thanks for the tip John.

120VAC Car Alternator Hack

at 11:19 pm. Filed under Crazy Hacks

 

If you like to see some real backyard hacking have a look at this video by kurtscottage. He is spinning an old car alternator with a gas motor and with a bit of rewiring and connecting through some home made transformers he is able to generate 120 VAC. Now the frequency is not always 60 HZ so I am not sure I would connect my laptop charger the the make shift power source but some resistive lights won’t be bothered by the non standard frequency.

CRT TV Flyback Transformer High Voltage Power Supply

  CRT TV Flyback Transformer High Voltage Power Supply_2

 

We have seen lots of interesting projects made for little money using scrap electronics like Microwave Ovens, for this project you will need a piece from another throw away item, a CRT TV.  This CRT TV Flyback Transformer High Voltage Power Supply by Robert Gawron is cheap and easy to build since the main part can be found for free in a discarded old TV. It sure makes for a crazy looking jacobs ladder.

“Old CRT monitor or TV is a great source of electronic components that can be used in DYI constructions. One of them is a flyback transformer that can provide 10-30kV output. The input voltage can be in a range from a couple of volts to over a dozen of volts, power consumption is a couple of watts. In my construction input voltage is 9V, power consumption is 5W.”

Pocket NC 5 Axis CNC Mill

at 2:33 pm. Filed under Cool Gadgets

If you shop is in need of a new toy a Pocket NC 5 Axis CNC Mill might be just the thing! I have had so much fun with the Laser machine and the CNC machine that I have but none of the equipment I have is well equipped to work with metal. Also a basic CNC machine can only move in the X and Y axis and drop the cutting bit in the Z axis. This Kickstarter would get you the Pocket NC 5 Axis CNC Mill which is a true 5 Axis machine for $3500 (24 left at that price at the moment). Have a look at the blog, it is interesting to see that they are ramping things way up with the purchase of a HAAS milling machine! They are also getting their prototype boards made at OSH Park (listen to this podcast for their history). The machine looks to be very sturdy and can make some incredibly intricate parts!

AD9833 Waveform Generator

at 3:47 pm. Filed under Cool Gadgets

 

Julian Ilett has a look at a AD9833 Waveform Generator.  It looks like a nice device. Connect a microcontroller to it and use SPI to interface to it. You can set it up for square wave, sign wave or triangle wave all through SPI.  The AD9833 looks like it could be very useful whenever you need to easily generate specific frequencies. The module that Julian is using was under $7 with free shipping.
