  1. Re: Modular system for assisting people with cerebral palsy

    Hi CasperH, thanks! :) I've finished the new energy source module. I ditched the inverter and now use 4 step down regulators, 3 for each different system: 1 x 12V (robot/screen) 1 x 19V (laptop) 1 x...

    Re: SPDT pushbutton and on-off switch

    Just to let everyone know. The item I talked about http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=281268944423 just works perfect, it needs a 12V input and can handle 10A for 30VDC or 250VAC, you...
  6. Re: Serial communication between Arduino and Arbotix

    Hi, sorry for the late replies, I'm also working on some 3D scanning stuff and I'm a bit overwhelmed with work (not sleeping is bad...) The problem with the Mega is that I cannot use it easily as a...
  7. Re: Hacking a LED voltimeter + thermometer to test battery with alarm

    Yes, you are right, after seeing how difficult would be to reprogram it, using components is the best choice. I just wanted to try to set something easy and compact using already made components, but...

    Hi everyone, I was wondering if it would possible to hack one of those cheap LED voltimeter + temperature modules...
  9. Re: Serial communication between Arduino and Arbotix

    Hi, sorry I took so long to reply. Right now I'm doing some upgrades, specially with the connectors and voltage regulators, to make it more energy efficient. I'm also upgrading it's "waterproofness"....

    SPDT pushbutton and on-off switch

    Hi, I have this problem and I'm sure someone has an easy and cheap solution. I have an emergency system on a powered wheelchair, to stop it with a SPDT pushbutton. When I push it, it actuates a...

    I just created a project here with a full description: http://forums.trossenrobotics.com/robots.php?project_id=61

    Also the question about the serial communication is being discussed here:...
  14. Re: Serial communication between Arduino and Arbotix

    Yes, the system is modular, so you can have the PC removed (the PC appears in the feeding video but it was there just because I had the table on me and I couldn't remove the PC by myself :D) It has 4...
  15. Re: Serial communication between Arduino and Arbotix

    Hey, that sounds great. One "problem" that I have now is that the Arbotix is not compatible with many shields, like the USB host or microSD. Whenever I use PyPose to change the poses of the arm I...
  16. Re: Serial communication between Arduino and Arbotix

    Well, I don't need something extremely fast, I just want to send commands through serial following some inputs devices connected to the Arduino (buttons, gamepad, serial commands from the PC)

  19. Re: 6 external hobby servos in ArbotiX Analog inputs

    Thanks jwatte, I thought it could be something like that, but with a 12V 5A power source and just using 2 ext servos I thought it would be enough.

    What do you mean with "Make sure the servo power...
  20. 6 external hobby servos in ArbotiX Analog inputs
