Touring The Future With Texas Instruments
The author’s veins on display

Yes, those are my veins.

This series of images was generated by the Christie DLP VeinViewer [PDF]. This device projects infrared light onto your hand. A camera detects areas with blood vessels near the skin because blood doesn’t reflect the IR light, but the surrounding tissue does. The resulting image is projected onto my hand by a interesting Texas Instruments technology, the DLP digital imaging chip. DLP technology is essentially a super tiny array of movable mirrors. Each mirror, 1/5th the width of a human hair, is individually controlled to reflect a pixel of light in 1024 values of brightness. In advanced applications, a DLP projector can create up to 35 trillion colors.

I was treated to demos of DLP products and much more during a behind-the-scenes tour of Texas Instruments at a recent media day. Here are a number of cool things that TI showed us which may have an impact on your hardware projects in the future:

The LightCrafter Structured Light Projector For 3D Scanning

High Accuracy 3D Scanning Using DLP Projector

The Microsoft Kinect has brought the concept of 3D imaging with structured light into the mainstream. The TI LightCrafter uses the same physical principles and is designed to generate 3D images with sub-millimeter precision. Target applications include industrial inspection, but Texas Instruments has built a development module that can be put to use in a wider range of settings.

The 3D Optical Metrology process is easy, and using DLP technology, delivers high quality results:

  • Patterns of light project onto a target
  • A camera or sensor captures the light distortions on the target
  • Data are then analyzed by a processor
  • The result is very detailed, 3D point cloud information (x,y,z) about the target

One of the more interesting possibilities is detecting cracks or flaws in things like carbon fiber bicycle parts with the LightCrafter and a good camera. The LightCrafter module is $600, which seems a reasonable price for a completely hackable projector. Better yet, TI provides a GUI tool to configure and control the LightCrafter, simplifying development and testing.

The DLP Dashboard

TI DLP Virtual Car Console in Audio Player Mode

I enjoyed seeing this demonstration of DLP technology that went beyond projecting home movies. This “virtual console” system projects an image on the rear of a translucent screen, shaped like the center console in a car. A camera also mounted behind the screen can see objects that touch the screen and is used to track the user’s fingers, which a computer interprets as input.

The entire curved screen was touch-sensitive. There were knobs mounted on the front of the screen that actually worked like real knobs, even though they had no electronics. They did have a pattern printed on the back, visible through the screen and captured by the camera, giving precise feedback for the knob position.

MSP430, A Low Power Leader

TI continually strives to be the industry leader for ultra-low power processing. My first introduction to ultra-low power embedded processing was in the late 1990s with early versions of the MSP430 family of 16 bit micro controllers, one of the few products on the market featuring power consumption in the sub-milliwatt range. Today, TI faces strong competition with manufacturers like Microchip for ultimate lowest power, but the MSP430 features an ultrafast wakeup time, minimizing power draw for applications that require intermittent use, like measuring temperature. For projects that run off batteries or harvest power from the environment, this is really useful and important. The low power 16 bit architecture makes this an appropriate product for projects that involve remote communication, wireless sensing, health & fitness, small battery powered robots, and more. Be on the lookout for TI’s newest member of the MSP430 family, codenamed Wolverine. It claims to cut running power consumption in half and features energy-saving FRAM, which will definitely improve power consumption in sleep mode.

Digital Signal Processing

What is a DSP and why do we care? In short, signals are all around us, from our own voices, to what we see around us, to the data wirelessly flying in every direction, to the measurements keeping car engines running smoothly. Without some way of quickly making sense of this information, modern day life would stop. Every day these important products, like cellphones and hearing aids powered by DSPs, get smaller. Part of the size reduction is due to smaller, smarter electronics, and part is due to smaller batteries powering more efficient electronics. TI showed me a well-rounded offering of new DSP chips that claimed improved power efficiency and improved speed for converting real world signals into useful information.

These chips are incredibly complex though. Remember programming your TI calculator? Maybe not. If you did, it was probably pretty difficult the first time, and that first impression matters. Texas Instruments is aware of the challenge developers face with increasing DSP complexity. They were eager to talk about how they were delivering better out-of-the-box development tools with the new release of Code Composer Studio, their primary DSP dev tool. TI’s DSP product line covers the high bandwidth C6000 and C5000 family DSPs, but they also have some intriguing low cost parts in the C2000 [PDF] line. Although TI doesn’t really consider their C2000 family of parts to be true DSPs, they are useful for many low-end signal processing applications. TI mentioned future innovations for the C2000 low power processors, including power consumption as low as as 50mW while running at 200 MHz, and a growing library of easy to use software modules for applications like energy measurement and control. They envision the C2000 products being used in applications like mobile robotics and micro-grid products. Eagle libraries are also on the way, as are new development boards and Mac compatibility.

Motor Control

There are over 10 billion electric motors manufactured every year around the world and Texas Instruments wants to control them all! The TI folks wanted to be sure that we knew 40% of a typical home electric bill is consumed by an motor, and that better motor control could cut power consumption by more than 1/3, saving all of us a lot of money and reducing wasted energy significantly. The technology exists, they said, but it has been too expensive and hard to use. Thus TI is developing better, cheaper, faster motor control algorithms that will be “software peripherals” pre-programmed into their DSP products. They showed a product called InstaSPIN, which claimed to solve problems like starting and reversing motors without requiring position sensors, and optimizing motor efficiency when not running at full load. TI also claimed that they had reduced the time it takes to figure out a motor control strategy from several weeks to several hours. I’ll have to see it to believe it!


We recently covered this promising product, and will continue to do so. It is a powerful, inexpensive, and tiny board that can be set up to run Linux in seconds. There is also a great community of developers creating applications and tools for it. At $89, it is definitely recommended to get you started with embedding Linux in your next project.

The Pandaboard is something I’m looking forward to getting my hands on. It is a powerful single-board computer featuring a multiprocessor architecture, graphics acceleration, HD video and dual display capability, and a very rich set of communication interfaces:

  • Onboard 10/100 Ethernet, 802.11 b/g/n
  • Bluetooth® v2.1 + EDR
  • 1x USB 2.0 High-Speed On-the-go port
  • 2x USB 2.0 High-Speed host ports
  • General purpose expansion header (I2C, GPMC, USB, MMC, DSS, ETM)
  • Camera expansion header

This all comes on a tiny 4″x4″ board. The processing power is impressive, and it should be easy to connect this to lots of peripherals. Hopefully the tools are easy to use. If so, this could be a hit with exhibit designers at museums everywhere!

There is a lot more interesting and innovative things going on at TI, including a host of analog technologies from motor drivers to analog conversion to power management. I hope to cover some of this in future posts, especially as I get my hands on some of the hardware and run it through its paces!

    They have one of these on display to play with at the Pink Palace Museum in Memphis, TN (awesome place btw). Really fascinating to play with, it’s what a heroin user in Blade Runner would have.

  2. Chrome6 says:

    I have used one of these in the hospital, works very well on adults. Premature babies, not so much.

  3. Jon Danforth says:

    I enjoyed this post quite a bit. I wasn’t previously aware of the diversity of products and technologies coming out of TI. I always assumed that TI was producing stuff that is simply *inside* the stuff I already buy but I never thought about them as a provider of prototyping or development hardware like the beagle bone or the MSP series boards.

    I’m especially intrigued by that MSP 430 board since I’ve been gnawing on the idea of building a remote weather station powered by wind and/or solar.

    1. Kipp Bradford says:

      I have to say that I was a bit surprised myself with everything going on at TI. I generally expect large companies to have substantial R&D and a large number of products, but TI has over 45,000 products. I would think it is important to create lots of design and prototyping tools to help people use all those products. I definitely got the feeling that TI knows this, and they are trying to devote more resources to building a user community. Even so, my observation is that there are a couple folks at TI who are driving community tools like the BeagleBone and the Launchpad products, but it’s not a company-wide effort. I’d love to see TI create a group at the Kilby Lab focused on improving developer experience, rather than just making improved chips.

        It’s a movement that is gaining momentum with success stories here and there. Moving a large machine such as TI is difficult to do in a short period of time. However, sharing success stories helps the movement significantly! It’s easier to stand in front of the developer’s committees and show examples of what can be done — and what could possibly been done if the software was ”xyz”.
        I do encourage you to take a peek at some of our amazing community members activities! Although not officially working with TI they are quickly bridging the gap where our standard offering falls short. A good community aggregator site is
        Needless to say, I’m excited that you were able to be given a tour of TI. If you ever want to get more info– or would like to have others come, please don’t hesitate to contact us! Hopefully we (some of us will be attending the OHS and then NY MF) will see you in September!

    There are pockets within TI that appreciate things like open source and developer experience, but you have to realize TI is a huge company. Most of our employees don’t ever deal with our chips from the developer perspective. Tons of work goes into things like architecture definition, test, and quality assurance which help to differentiate us from our competitors.

    Those of us that do work on the chips from a developer perspective try our best to make things as easy for developers and Makers as possible. I actually was a TI customer before I was a TI employee, so I have a good appreciation for the frustration that sometime comes with development. I strive everyday to make TI products easier for our customers to use.

    All that being said…We’ve got some exciting things up our sleeves that I’m sure you Makers will love! Keep watching for the next big thing!

  6. Toxic? says:

    Speaking of the “the next big thing” and 3D scanning- I have not seen any coverage from MAKE on the ‘Leap Motion’…

    Sure looks like a disruptive technology to me.

  7. Toxic? says:

    Is there an official way to post items of interest or suggest them to ‘authorized post-ers’?
