  1. We made a video describing the whole project- check it out!
  2. Board all soldered up and working! Hopefully we'll have some demo videos out soon.
  3. Design is finished and sent to the fab! It's now been christened as "BoosterBot".
  4. Board routing is pretty much complete! Still need to add in ground planes and do a DRC. Also, the hole for the ball caster in the middle is made of three overlapping drill hits at the moment, which isn't supported by the fab. I'll have to change it to a cutout, which I'm not feeling too great about.
  5. Yep, we're mounting a ball caster on the front to keep it balanced.
  6. The idea is that everything mounts straight onto the BoosterPack so the board itself is the chassis. You can see that the motors are mounted straight onto the BoosterPack in the back of the image. This is for the Intern Design Contest so keep an eye out for it! Your BoosterPack looks really nice as well. I've used the Magician Chassis before and it's great.
  7. https://www.dropbox.com/sh/jrogxsmuv0zul65/AAAEET4Bxoq1iO3496Pk3dqOa Placement is pretty much done now. I'm concerned that some of the tall tantalum caps and inductors will scrape the ground, as they're on the bottom of the board. I'll have to flip them to the top if there isn't enough margin.
  8. Quick update: https://dl.dropboxus...oosterpack2.png The five sensors up at the front are reflectance sensors on the bottom of the board for line tracking and maze solving. The middle three are for PID line following, and the two at the edges are for recognizing splits in the track.

It's a BoosterPack that turns a 40-pin Launchpad into a fully functional robot. It has two Micro Metal Gearmotors from Pololu driven by a DRV8833 motor driver IC and has five QRE1113 reflectance sensors from Fairchild for line tracking. It also has breakouts for a Sharp IR distance sensor and a servo. For power, a 3xAAA battery holder fits between the LP headers, which powers the 3.3V and 5V pins, as well as 9V for the motors. No pictures yet, as I'm in the middle of routing the board. I'll post updates as they come. Edit 6/30: A picture of the board in progress: https://dl.dropboxusercontent.com/u/538662/robot-boosterpack.png You can see the motor mounts at the far end.

  10. I've made a daughterboard for the TI Evalbot using the EM connectors. It has a MSP430G2553, Xbee (Bluetooth Bee), and an XV-11 LIDAR. The goal is to eventually get SLAM working with it. The LIDAR (laser distance sensor, really) continuously rotates and reports distance values and angular velocity. The MSP430 controls the rotation with PWM and the velocity data, and acts as a SPI slave to the Stellaris on the Evalbot to report distance values. The XBee is connected straight to the Stellaris UART. Example of the LIDAR in use: http://youtu.be/KnspWPlBM_o I just got the boards in and soldered them up. Hoping to have some code written up soon. You can find the design files at: https://github.com/hylian/slambot PCB: https://dl.dropboxusercontent.com/u/538662/lidarpcb.png Pictures: http://imgur.com/a/VZSGb Video: http://youtu.be/v139k2DG388
  11. Hi all, I'm trying to get the Capacitive Touch Boosterpack working with the new F5529 Launchpad, but I'm a bit confused. I am trying to implement the "RO_COMPB_TB0_WDTA" example for the F5529 provided in the Capacitve Touch Library code examples. From what I can see, the timer measures the length of a single charge up over RC, which varies when C is changed, via the comparator, which snaps the voltage back to 0 after it fully charges. Diagram of RO taken from CapTouch Library Guide: http://i.imgur.com/chb09pR.png Diagram taken from the example: * c-+------------------R--+--<PortMap/TB0CLK/CBOUT * | | * | c-+-------------R--+ * | | | * | | c-+---------R--+ * | | | | * | | | c-+-----R--+ * | | | | | * | | | | c-+-R--+ * | | | | | * | | | | +------->CB0 * | | | +----------->CB1 * | | +--------------->CB2 * | +------------------->CB3 * +------------------------>CB4 Full source: http://pastebin.com/XKN8HXhc However, from looking over the boosterpack documents, it seems that the node between the resistor and the capacitor isn't broken out? I only see the node before the resistor broken out (TB0CLK/CBOUT above). The datasheet seems to imply the RO method is possible with this boosterpack; am I missing out on something important? Any help would be greatly appreciated. Thanks, Hylian (Also, sorry if this is the wrong board to post this in)
  12. Whoa, that image came out much larger than I expected. Well, it's a matter of personal opinion. I've had Macs over the years, and OSX is a nice OS, but usually end up sticking with Windows and Linux. My Mac Mini G4 is sitting in the corner running Debian still faithfully working as a home server. As for system upgrades, I would disagree. They've only been making it harder for users to get at system internals, which is a part of Apple's philosophy. The image above is a bit exaggerated since Mac Pro is crazy overpriced even compared to the other Mac lines, but I would argue that hardware price difference is still fairly large. As a rule of thumb, the base line models are probably ~$230 over what it would cost to build yourself, with upgrades beyond that costing significantly more. What you do get though, is a sexy case and hipster points from your friends. :>
  13. Sorry to be the naysayer here, but I would much rather go for building my own PC than buying a Mac. The price premium is just too large for not that much in return. If you're set on buying Mac, I would say MBP.
