Hi everyone, I just wanted to show an update of something I’ve been working on. I’ve been in the works of a board game called Heifer Heist that I am hoping to bring to Kickstarter later this summer! We just launched our new website at heiferheist.com, and we can also be found on Facebook and Twitter. If you like this game, do support us and share, like and follow and I’ll try and keep everyone updated on how when the Kickstarter will be launching and how the process is going!

I haven’t written about wallets in quite a while, but I always love a simple slim wallet designed with the minimalist in mind. The Sapling Aluminum Series wallet was designed by John McConnell. The slim design of the wallets allow you to carry it in your front pocket which makes your wallet more comfortable and secure.
The wallet features a unibody design machined from a solid block of 6061 aluminum which is an RFID blocking material.This means that your cards are more secure against card skimming, an increasingly more common method of card theft. The wallets are anodized to add a look that will hold up over time and will also allow us to add a custom name engraving with a laser engraver.
The design includes an elastic band which allows the wallet to expand to meet your needs, holding 1-8 cards.The height of the card slot is the equivalent to the width of 5 cards but because of the elastic band design, the wallet is capable of holding more and is still fully functional if you decide to add more cards.
The elastic band also stretches lengthwise across the back of the wallet allowing you to store cash or cards on the inside or outside of the wallet, much like a money clip would. The slotted design allows for fast and easy access to all of your cards.The elastic band is also conveniently placed so that the numbers on your card are concealed from view when the wallet is being removed from your pocket.
There are only a couple days left on his Kickstarter here, so support it soon if you’d like a wallet of your own!

German physicist Heinrich Rubens became a god among nerds in 1905 when he invented a tube that uses fire to visualize standing sound waves. When there is no sound fed into the tube, the flames rise to the same height. When a sound is added into the tube, the waveform actually affects the amount of gas that is fed through each hole.
At the point of maximum displacement on the wave (the anti-node), the gas pressure varies. The pressure is highest when the wave crests and the gas is pushed closer to the hole, which forces more fuel out and causes the flame to grow higher. When the wave pushes down into the trough, it can’t really suck the gas back in. The flame has enough gas and oxygen to remain burning higher until the wave crests at that point again.
The part of the wave which crosses the midline and remains unchanged is referred to as the node. This area in the Rubens tube doesn’t have the pressure fluctuation and remains relatively low.
Of course, volume plays a big role on how these flames appear. The above description applies when the volume is high, but if the incoming sound is quiet, the crest of the wave isn’t enough to overpower the opposite pressure of the trough, and the anti-nodes actually appear smaller than the nodes.
Derek Muller from Veritasium traveled to Denmark in order to check out an updated version of the Rubens tube. These physicists and chemists have developed an apparatus with 2,500 holes in the top. The key difference is that these holes are not all in a line like a traditional Rubens tube, but actually cover an entire plane.
The results are pretty amazing. Check it out:

I’m always a sucker for tiny things but also have a great love for robots, so when I learned about these micro-robots, I really got excited. We’re all familiar with ant colonies, where every tiny creature is running around doing just what it needs to. Well it looks like SRI International has taken inspiration from the giant mounds of insects, to create their own swarms of tiny worker robots that can put together mechanical assemblies and electronic circuits.
Diamagnetic Micro Manipulation (DM3) uses tiny magnets that move under a circuit board, to get the micro-robots to follow a set pattern based on a set of preprogrammed instructions. The system can be set up so just one or a couple of robots are working together, or you can have giant groups of them moving together in sync like some bizarre gymnastics routine. Despite their tiny size, the robots can move up to a foot in a single second, so they can haul around your micro manufacturing supplies pretty swiftly.
SRI says that DM3 can be used for prototyping parts, electronics assembly, biotech lab-on-a-chip experiments, and assembling small mechanical systems in hostile environments. Eventually they plan to scale up the technology, by developing a manufacturing head containing thousands of the little buggers that can build much larger assemblies.
As you might expect, the funding comes from the military, and is part of DARPA’s Open Manufacturing program.
Check out the video of the tiny robots in action, you’ll be surprised by how fast and accurate they can be:

There’ll soon be no need to ever take off wearable technology as your body heat will be able to run a generator to keep it powered-up.
Thanks to a new invention by scientists in Korea heat that escapes the body can be converted into energy using the generator that can be curved along with the shape of the body.
The researchers developed the glass fabric-based thermoelectric generator to be light and flexible which could help to further commercialise wearable technology.
Byung Kin Cho, who led the team in creating the generator, said that with more development the technology could be used on a large-scale to stop heat energy not being used.
At present wearable technology, such as the activity tracking Fitbit Flex wrist band, is developed with long-lasting battery life – the Flex has a battery life which can last up to five days.
However the latest technology would remove the need to ever take wearable technology off, which can cause some users to stop using their gadgets.
It also comes with the benefit that using thermal energy to power and recharge wearables would not need to use any energy created by non-renewable forms.
The small generator was created and tested on small bracelet and it is said it can be able to provide power in a stable and reliable way.
Cho further described how the generator could be used, he said: “Our technology presents an easy and simple way of fabricating an extremely flexible, light, and high-performance TE generator.
We expect that this technology will find further applications in scale-up systems such as automobiles, factories, aircrafts, and vessels where we see abundant thermal energy being wasted.
So far only two types of thermal energy generators have been developed, these have been based on either organic or inorganic materials.
Until now the organic generators have been able to work with human skin but have not been able to generate enough power to be put to practical use.
While those made of inorganic materials have been able to generate enough power but have been too bulky to be able to be used with wearable technology.
Cho came up with the a concept and design technique to build a flexible TE generator that minimizes thermal energy loss but maximizes power output.
The new concept uses liquid like pastes of thermal electronic materials printed on to a glass fabric.
When using the generator, with a size of 10cm by 10cm, for a wearable wristband device, it will produce around 40 mW electric power based on the temperature difference of 31 °F between human skin and the surrounding air.

I haven’t been posting recently because I have been working on this boardgame called, Heifer Heist! In a nutshell,
Heifer Heist is a classic story about aliens, cows, and a great escape. The players are aliens who have crash landed on a planet and “borrow” cows to power their motherships to return to space. During their cownapping quest, they must dodge the angry farmer, who’s got beef with them!
This is possibly my favorite project that I have worked on with my friend, Jess. We entered it into the Champaign-Urbana Design Organization’s (CUDO) boardgame competition and won the award for Best Visual Design and Most Marketable.
We have had the awesome opportunity to show and play our game with several designers at Deep Silver Volition, and now in the process of creating a Kickstarter for it!
Check out the design process!

World’s First Wireless Smart In Ear Headphones. 1000 Songs. Performance Tracking. Body Sensors. Secure Fit.
Music is a part of everyone’s life. It brings joy, excitement and motivation. However it is not always a pleasure listening to music with headphones. Cables tangle and pull at the headphones and ultimately break. In addition, accessing online content from a smartphone is awesome but needing to carry a smartphone all the time can be a real pain.
The Dash consists of a pair of discrete and completely wireless stereo earphones.They will playback music through a Bluetooth connection or use the embedded 4GB/1000 song music player. Everything about the design is focused on delivering freedom of movement, incredible sound and comfort. The Dash is awesome for sports and great for everything else.
The Dash works in sympathy with the wearer. Movements like pace, steps, cadence and distance are tracked. Heart rate, oxygen saturation and energy spent are measured, all the while real time acoustic feedback is provided. It even works without an attached smartphone.
Safety and the ability to communicate with others are important. In addition to being earphones, the Dash will double as a Bluetooth Headset delivering clear voice quality through the embedded ear bone microphone. The ear bone microphone is not sensitive to background noise, since it picks up mechanical vibration generated by your voice from the ear bone.
Even though The Dash provides impressive noise isolation, the wearer can choose to channel ambient sound into the headphone with the transparent audio feature. A swipe on the capacitive touch surface of The Dash will enable or disable ambient sound to pass through.
You can support their Kickstarter here!
