H-Bridge Wiring And Using A Motor/Gearbox Combo

Hello DJ Sures! Got a few questions for you from a robotics newbie: First, could you breakdown the wiring of the Sparkfun Dual Motor Driver? I saw the new video that was posted but still couldn't follow the wire to port progression. I tried looking at the schematic for the driver but there were more ports on that than the chip! So, could you break...

I live in Sweden and though i would share my ideas before i throw myself into something im not sure will end well lol Ok so i will begin with an intelligent robotic arm.

E-Mail And IM Notifications?

I'd like to build a robot that would let me know when I got E-mail from certain people, and possibly notify me if I get an IM. I don't have much use for remote controlled toys, but something like that would actually be very useful to me. I could make something like a "nabaztag rabbit internet", only in the form and shape I desire. Is...

Missing Posts

Hey there! So last night we had a hard drive crash. Sad thing is, the database wasn't backed up for 2 days. I had been building a new server and had the backup disabled, thinking "what could go wrong in 2 days?". Well the HD died. All orders are recorded through paypal, so there are no problems there. However, some user accounts that were...

Support For Nxtsumoeyes...

DJ How difficult would it be to get this Dual Range Triple Zone Infrared Obstacle Detector to work with the EZ-B/EZ-Builder? This little guy seems perfect for tunable object detection/avoidance. Would love to use it on the Little WALL-E project...

ARC For IOS?

Ok DJ, Seeing how you mentioned there's only one of you on the Linux thread (we could clone you ), perhaps we can draw you out again. Don't see any Mac software at all. Now I am a multi facited Nerd and play in many environments and think with the advent of tablets taking over the laptop sales you might want to consider it! I think an iPad would be...
