Other Parts Discussed in Thread: CSD16301Q2, CC2500

Hi folks,

here's my entry for the Boosterpack contest.

The purpose of "rover" is just to provided a fun platform that can demonstrate TI-RTOS drivers; in particular the I²C, SDSPI (SD card support via SPI), UART, and CC3000 drivers.

As you can see, the rover hasn't been fabricated (as it wasn't a requirement and hence the cardboard mockup :) ) but an example of the TI-RTOS software has already been developed by a former TI intern (Kevin Q.) on his Evalbot Controller (on the left).

The board itself doesn't come with the Tamya tank kit (~$20), but it's been designed to take in flexible range of power supply inputs (3V-16V) so it can work with other chassis. The bulk of the peripherals are I²C peripherals that allow for basic IR object detection, RGB LED indicators, inertial measurements while allowing additional boosterpacks to be added for wifi/bluetooth communications.

TI components:

DRV8801PWPR: Motor Driver
TLC59116IPWR: I2C LED Driver
CSD16301Q2: Power MOSFET
TCA6408APWR: I2C GPIO Expander
TPS62140RGTT: Buck Converter
TL1963ADCQR: Low Dropout Regulator

Compatible with:

Stellaris LM4F120 Launchpad
CC3000 boosterpack
CC3000 LSResearch module
CC2500 Panasonic Bluetooth module

InstaSpin QuadCopter

Other Parts Discussed in Thread: CC2560, ENERGIA, MSP430F2274, CC2500, DRV8301, CONTROLSUITE

Status Update #1:

http://youtu.be/Kkeyz3raP-M

The board contains 4 special piccolo devices which have a sensorless software
encoder in ROM. The Piccolo devices sense each phase current and
voltage and calculate the flux vector inside the motor in real time. This gives
them the ability to precisely place another flux vector to drive the motor with
incredible efficiency.

Balance and control are implemented using a standard suite of 3 axis
accelerometers, gyroscopes, and magnatometers, while communications are
implemented using the CC2560 bluetooth controller. Additional navigation
information can be provided by a CC4000 based GPS module which will allow for
completely autonomous flight.

When completed the InstaSpin Quadcopter will run the Arducopter software which
allows us to leverage a large amount of free open source third party software to
provide additional functionality. Phone or PC based software can be used to
both fly the quadcopter and program the quadcopter for autonomous "drone"
missions.

The question I get most when I show off the quadcopter is "Will this thing
fly?". The answer to that question is yes, but not yet! This is a big project
and the PCBs are less than two weeks old and are still being assembled. That
said, this design is based off another quadcopter with a similar size and shape
that uses the same motor prop combination that I have used. The instaspin
quadcopter weighs in a little heavier, roughly 50 grams, but motor size can
easily be increased and weight decreased for a production version of this board.

You may be curious how much this thing costs. While designing the
board the goal was to keep it as low cost as possible. Final BOM cost in a
production environment would likely be near $50 including motors and a battery.
And while this may be over the $40 limit of this competition, I think the fact
that you can now "Launch" a launchpad more than justifies the extra $10 spent.
Finally, because of the way the motor controllers are implemented on the board,
this boosterpack should be compatible with all LaunchPads.

Well thats ends the introduction to the InstaSpin QuadCopter BoosterPack.
Don't forget to vote for me if you'd like to see this boosterpack turned into a
real kit.

Standard Disclaimer:

This design is a work in progress, it is not perfect and there are probably flaws in it I have yet to find. Should the design be put into production much more additional work will be done to ensure a quality BoosterPack that launches LaunchPads!

Bluetooth Audio Amplifier BoosterPack

Trey German289 — Mon, 08 Apr 2013 02:53:43 GMT

Other Parts Discussed in Thread: TAS5613, TAS5611

The Bluetooth Audio Amplifier Boosterpack has many uses and has a wide target
audience. The original project idea was to give tubers a way to make their own
DIY cooler stereo. Currently, a few companies offer prebuilt coolers with
speakers, but none offer kits that are designed for the DIY'er and none offer
bluetooth connectivity. Uses aren't limited to coolers as this board can be
used to provide music anywhere there is 12V. In fact many pedicab drivers have
expressed interest in a board like this.

The board contains two main subsystems: a 4 phase boost converter, and a 300W
Class D amplifier. The multiphase boost converter which is based on a TI
reference design is used to pump up the 12V from a lawnmower or car battery to
24V which is used as the main supply for the amplifier. The amplifier is
implemented using a TAS5613. The TAS5613 is a 300W Total Stereo class D
amplifier. Becuase of the switching nature of this amplifier it is very
efficient and perfectly suited for the battery powered applications this board
is intended for.

The LaunchPad in this design is used for control of the bluetooth audio module.
Because of time contraints, I've implemented this board in a very simply fashion
which does not show off all that the LaunchPad is capable of, but with more time
for development this could certainly be improved. Future improvements would be
using one C2000 LaunchPad to control the boost converter and replacing the Class
D amplifier chip with another C2000 LaunchPad and a discrete power stage to implement
a Class D amplifier. Additionally a TI bluetooth audio solution could be
integrated with this board with some additional resources.

As implemented current BOM cost is right around $60, but the board is over
designed. A production version of this board would easily hit the $40 mark.

Other Parts Discussed in Thread: DRV8834, DRV8412

Dual Bridge Stepper BoosterPack

This BoosterPack utilizes a Texas Instruments DRV8834 (2.2A Low Voltage Stepper w/ 32-step Indexer or Dual Brushed DC Motor Driver) and was mainly designed as an expansion to the MSP430 LaunchPad ecosystem.
As indicated by the used IC above it can drive one stepper or two brushed DC motors. Four LEDs at the edge of the PCB give an overview of the 'enable', 'step', 'direction' and 'fault' stati.
It also comes with an easy to use library for the MSP430 LaunchPad. (At https://github.com/iOperator/stepperbooster)

Here is a video of the Stepper BoosterPack in action!

The BoosterPack was designed to be low-cost. The BOM of the single prototype is only 2.75€/$3.50 (without PCB and TI DRV8834).

Bluetooth Home Automation BoosterPack

Mark Easley — Fri, 05 Apr 2013 23:28:22 GMT

Other Parts Discussed in Thread: CC2560

Description:

This BoosterPack mockup demos how a TI cc2560 Bluetooth module interfacing with LaunchPad can enable end users to control lighting applications with traditional physical actuation as well as digital actuation via a smartphone or tablet app. The software allows you to scan and pair with nearby Bluetooth embedded devices in your home or office and allows you to actuate the integrated solid state relay. This BoosterPack also has the ability to integrate with other components like haptic or capacitive touch elements to enable more modern lighting control user interface and user experience.

This allows a user to control household electric appliances and lighting while seated or on the other side of the room. This is the future of home automation and connectivity. The automated home will require multilayer networking with Bluetooth, WiFi, and Zigbee enabling different applications.

The final BoosterPack would have an integrated cc2560 module, relay or TRIAC, and AC powersupply for drop in, out of box LaunchPad lighting demo. BoosterPack can be configured to support in wall operation for lighting, or smart socket operation for appliances.

TIPhoon Booster Pack

Divya Alok Gupta — Wed, 03 Apr 2013 09:05:49 GMT

Other Parts Discussed in Thread: DRV8800

TIPhoon booster pack is a an addon to the MSP430 Launchpad. This booster pack provides full flexibility to control 2 types of motors namely the the DC motor and Servo motor. It employs TI's own DRV8800 Motor Controller which caters to all the requirements of a Brushed DC Motor. The Servo Motor is simply controlled by Pulse Width Modulation on a GPIO. The motors can be controlled by using an interactive GUI (designed in MATLAB) which interacts with MSP430 by following the UART protocol. It lets you independently choose the speed, direction and the precise angle through which you want to turn the motors. Not only that, there is also an option of interfacing up to 3 analog sensors with the MSP430 Launchpad. This feature enables the creation of a complete feedback system using Hall Effect sensors or Shaft Encoders or any other feedback control system which in turn makes motor control highly accurate.
