  1. Hey Sani, welcome to the forum. Lot's of helpful info and helpful people here. Let me know if I can help. P.S. still a noob. :grin:
  2. Update, so the launchpad link above does work!!!! It is awesome to use the launchpad through matlab, i suggest it for anyone else.
  3. Here is something worth checking out if you are interested in this topic: http://www.mathworks.com/matlabcentral/fileexchange/37825-simulink-embedded-coder-target-for-ti-launchpad I think this may be what I am looking for, there is just never enough time to do everything I want to do, as I am sure every other DIY'er on here will agree!!! :grin:
  4. ill have a look into it further, no dice just yet. Perhaps I will have to develop this on my own. Thanks for the reply blue. :thumbup:
  5. I'm trying to control a hexapod, 18 servos, no other sensors for now, using the matlab/simulink interface and a launchpad. Has anyone done this that may know of a beginner walk through for like a robtic arm, or a simple rolling bot? I've already done a simple one using Arduino, but I'm fond of the Launchpad.
  6. Also, I forget on here where I found this compiled list of short cheats for energia: http://f4dtr.files.wordpress.com/2013/06/energia_cheatsheetv01c.pdf But it is always good to have handy for noobs like me.
  7. Right!!. I'm thinking of multi camera angles. The replay would be initiated by the goal sensor led/photoresist. I'm just throwing ideas out there. If anyone has any other cool ideas I would love to hear for implementation. ~ Orso
  8. I may have to purchase this for my automatic scoring foosball project. I have just began the project on the forum. Best Regards.
  9. I'm having some trouble with the points being counted automatically. Using an LED with the photoresistor. I think I need a light with a more direct light. I wonder if a laser pointer would work with a photoresistor? Or, I guess I could direct the light of the LED with some kind of 3D print. more posts to follow. ;-)
  10. This would be cool to have so you know where all the empty spots are. Thus, you are able to park as soon as a spot opens up. Soon we will see this in smart cities.
  11. Also forgot to include the most important thing of all, the MSP. :? perhaps in the next video :wave: . bye for now
  12. some pics of the table at hand, and my first upgrade of many. The foosball table is a 1 goalie style, with the sloped corners. very fast play. The circuit I have set is a simple LED scoring system, wired to photoresistors that record a point as the ball passes over the goal, blocking the light of the photoresistor is shaded by the scoring ball. Check it out, looking forward to hearing any comments. thanks for reading this.
  13. I posted in another forum about using a lidar sensor for the automatic scoring, but I have not heard a response about finding a reasonably priced sensor. I guess that is a little overkill. I guess I should just go for the variable photoresistor. I have the circuit setup for the photoresistor. Pics to come soon!!! So excited about this project.
  14. Looking for some light weight, rechargeable batteries that may be suitable to power up to 18 servos for at least 30 minutes, running semi-continuously.
  15. Thanks Hex. I will put that on my bucket list. I have some beginning steps to make, and I still need to get some photos so you can see what I am working with. Best Regards
  16. Cool, thanks I have already sent this off to a few others. I will print it out and keep it close by.
  17. // * DATE: 1/21/2013 // * DESCRIPTION: Simple program to run 8 lead stepper motor at half-steps #include "msp430g2452.h" volatile unsigned short a = 1; volatile unsigned short i = 1; volatile unsigned short j = 2; volatile unsigned short k = 3; volatile unsigned short l = 4; volatile unsigned short m = 5; volatile unsigned short n = 6; volatile unsigned short o = 7; volatile unsigned short p = 8; /* MAIN */ void main(void) { WDTCTL = WDTPW + WDTHOLD; // Stop watchdog timer P1DIR &= ~BIT3; P1IE |= BIT3; P1DIR |
  18. Planning to beef up a really old, rickity, foosball table with some led's and photoresistors in order to automate my scoring. It is such an old table, having these sensors will be like placing a laser scope on a musket. But, I just can't resist. Maybe future projects could include cameras set up with instant replay, and including some audio into the game scheme, Or how about a scoring system to keep track of players records for a type of league play. Go Foosball!!! Pictures to come....
  19. I think it is a great project. The MSP430 will be plenty fast enough to sample the temperatures you are planning this for. I can't think of a way to do this on a lower budget than the MSP.
  20. Also, if you turn off lose power you may lose your position of your last step.
  21. here is what i used: I defined those constants to reference data written to the flash with the "Calibrate DCO With Checksum" program. There should be a copy of lnk_msp430g2231.cmd buried in the working directory for the compiler, renamed to lnk_msp430g2231_mod.cmd that has the new constants in it. You can check out this thread which explains clock calibration with the MSP430, custom clock calibration constants that result from running the calibration program, and what to do to be able to use those constants: http://www.43oh.com/forum/viewtopic.php?f=10&t=239 Basically, the MSP430G2X
  22. That seems like a lot of messing around, though I will try and make it work. Thanks for your reply J.
  23. hey jacques, welcome!! I also have a friend interning at my work from Paris.
  24. I ordered a few tower pro mg995 servos and was only able to control them through 120 deg. But when its powered off, I can manually turn the servo horn through 180. Has anyone figured out how to control through the 180, or is it just not possible? Thanks
