Sigzig Data Loggers Ditch The Noise While Pimping The Case

January 21, 2015 by 25 Comments

We ran into [Paul Allen] at CES. He was showing off Sigzig, a super-low noise data logger which his company is just rolling out.

IMG_20150107_174520A couple of years ago he worked on a standalone chemical sensor and had a few extra boards sitting around after the project was done. As any resourceful hacker will do, he reached for them as the closest and easiest solution when needing to log data as a quick test. It wasn’t for quite some time that he went back to try out commercially available loggers and found a problem in doing so.

The performance of off-the-shelf data loggers wasn’t doing it for [Paul’s] team. They kept having issues with the noise level found in the samples. Since he had been patching into the chemical sensor PCBs and getting better results, the impetus for a new product appeared.

The flagship 24-bit 8-channel Sigzig samples 0-5v with less than 1uV of noise. A less expensive 4-channel differential unit offers 18-bit with 10-12 uV of noise. They are targeting $199 and $399 price points for the two units. We asked about the sample rate in the video below. The smaller version shown here captures up to 240 samples per second. The big guy has the hardware potential to sample 30,000 times per second but since the data is continuously streaming over USB that rate is currently limited to much less.

Update: It has been pointed out in the comments that USB may not be the choke point for sample rate.

 

Clockety Uses Phone Flash For Projection Clock

January 15, 2015 by 100 Comments

[Gaurav Taneja] was showing off his projection clock add-on for iPhone called Clockety at this year’s Consumer Electronics Show. The concept is pretty neat, a clip-on clock which uses the iPhone flash LED as the light source. It may sound a little gimmicky until you see the functionality of the accompanying app which is shown off in the video after the break. Once clipped onto the phone, you lay it face down on your night stand and a gentle tap on the furniture will turn the projection on or off. This is a killer feature when you’re staying some place without an illuminated bedside clock.

The Giant Flip-Dot Display At CES

January 14, 2015 by 55 Comments

Flip-dot displays are grand, especially this one which boasts 74,088 pixels! I once heard the hardware compared to e-ink. That’s actually a pretty good description since both use a pixel that is white on one side and black on the other, depend on a coil to change state, and only use electricity when flipping those bits.

What’s remarkable about this is the size of the installation. It occupied a huge curving wall on the ooVoo booth at 2015 CES. We wanted to hear more about the hardware so we reached out to them they didn’t disappoint. The ooVoo crew made time for a conference call which included [Pat Murray] who coordinated the build effort. That’s right, they built this thing — we had assumed it was a rental. [Matt Farrell] recounts that during conception, the team had asked themselves how an HD video chat for mobile company can show off display technology when juxtaposed with cutting edge 4k and 8k displays? We think the flip-dot was a perfect tack — I know I spent more time looking at this than at televisions.

Join us after the break for the skinny on how it was built, including pictures of the back side of the installation and video clips that you have to hear to believe.

Jamming Robot Will Destroy You At Beer Pong

January 13, 2015 by 18 Comments

DSC_0363Wandering the aisles of Eureka Park, the startup area of the Consumer Electronics Show, I spotted a mob of people and sauntered over to see what the excitement was all about. Peeking over this gentleman’s shoulder I realized he was getting spanked at Beer Pong… by a robot!

Those in the know will recognize that the bot has only 3 cups left and so the guy definitely was giving it run for its money. But the bot’s ability to swish the ball on nearly every throw accounts for the scoreboard which read Robot: 116, Humans: 11. Unlike the ping pong robot hoax from last March, we can vouch for this one being real!

If you’re trying to attract the geek demographic, this must be one of the best offerings ever shown at a trade show. Empire Robotics manufactures the VERSABALL gripper. We know this as a jamming gripper and have been looking at the tech progress for many years now. Looking back to this Cornell research video from 2010 we realize it is based on the white paper which [John Amend, PhD] co-authored. He’s now CTO and Co-Founder of the company and was one of the people running the booth. We love it when trade show booths are staffed by the engineers!

Join me after the break for a rundown of how the system works along with a video clip of it hitting the target.

CastAR Hands-On And Off-Record Look At Next Version

January 12, 2015 by 30 Comments

At long last I had the opportunity to try out the CastAR, a glasses-based Augmented Reality system developed by Technical Illusions. The hardware has been in the works now for a couple of years, but every time we have come across a demo we were thwarted by the long lines that accompany them. This time I was really lucky. [Jeri] gave us a private demo in a suite at the Palazzo during CES 2015. Reflecting on the experience, CastAR is exactly the type of Virtual Reality hardware I’ve been longing for.

CES: Building Booths And Simulating Reality

January 7, 2015 by 15 Comments

My first day on the ground at CES started with a somewhat amusing wait at the Taxi Stand of the McCarran International Airport. Actually I’m getting ahead of myself… it started with a surprisingly efficient badge-pickup booth in the baggage claim of the airport. Wait in line for about three minutes, and show them the QR code emailed to you from online registration and you’re ready to move to the 1/4 mile-long, six-switchback deep line for cabs. Yeah, there’s a lot of people here for this conference.

It’s striking just how huge this thing is. Every hotel on the strip is crawling with badge-wearing CES attendees. Many of the conference halls in the hotels are filled with booths, meaning the thing is spread out over a huge geographic area. We bought three-day monorail passes and headed to the convention center to get started.

Building the Booths

Slot-car “brain racing” with scoreboard

[Sophi] knows [Ben Unsworth] who put his heart and soul into this year’s IEEE booth. His company, Globacore, builds booths for conferences and this one sounds like it was an exceptional amount of fun to work on. He was part of a tiny team that built a mind-controlled drag strip based on Emotive Insight brainwave measuring hardware shipped directly from the first factory production run. This ties in with the display screens above the track to form a leader board. We’ll have a keen eye out for hacks this week, but the story behind building these booths may be the best hack to be found.

Oculus

[Ben] told us hands-down the thing to see is the new Oculus hardware called Crescent Bay. He emphatically mentioned The Holodeck which is a comparison we don’t throw around lightly. Seems like a lot of people feel that way because the line to try it out is wicked long. We downloaded their app which allows you to schedule a demo but all appointments are already taken. Hopefully our Twitter plea will be seen by their crew.

In the meantime we tried out the Oculus Gear VR. It uses a Galaxy Note 4 as the screen along with lenses and a variety of motion tracking and user controls. The demo was a Zelda-like game where you view the scene from overhead. This used a handheld controller to command the in-game character with the headset’s motion tracking used to look around the playing area. It was a neat demo, I’m not quite sold on long gaming sessions with the hardware but maybe I just need to get used full-immersion first.

Window to another Dimension

DSC_0317

The midways close at six o’clock and we made our way to the Occipital booth just as they were winding done. I’ve been 3D scanned a few times before but those systems used turntables and depth cameras on motorized tracks to do the work. This uses a depth-camera add-on for an iPad which they call Structure Sensor.

It is striking how quickly the rig can capture a model. This high-speed performance is parlayed into other uses, like creating a virtual world inside the iPad which the user navigates by using the screen as if it were a magic window into another dimension. Their demo was something along the lines of the game Portal and has us thinking that the Wii U controller has the right idea for entertainment, but it needs the performance that Occipital offers. I liked this experience more than the Oculus demo because you are not shut off from the real world as you make your way through the virtual.

We shot some video of the hardware and plan to post more about it as soon as we get the time to edit the footage.
