Re: NXT 2.0 Mainboard burned

I am guessing that is L1 (15uH inductor) in the power regulation circuit. You can find the schematics to the NXT in the hardware developer kit. <http://www.lego.com/en-us/mindstorms/downloads/nxt/nxt-hdk/> The part got too hot and melted the plastic/rubber, which means it had too much current runnin...

Re: can labview be used with the EV3 brick??

For a kill switch, I would hook up a power supply directly to the EV3 instead of using a battery. Then turning off the power supply will kill everything.

Re: Is there any effort to coordinate EV3 sensor type IDs?

Right. Part of it is "straight from the sources". It contains all of the LEGO brand sensors. But the first link is a file that looks to be made John Hansen. It assigns type numbers (the first column) for all/most of the Hi-Technic I2C sensors. I am just wondering if anyone has assigned type numbers ...

Is there any effort to coordinate EV3 sensor type IDs?

I am referring to https://github.com/mindboards/ev3sources/commit/5ac5c41e455b7a5eb7a0cbde9488afea39d00802 I am wondering if LEGO has an "official" list (other than https://github.com/mindboards/ev3sources/blob/master/lms2012/lms2012/Linux_AM1808/sys/settings/typedata.rcf) or if the Mindstorms hacke...

Re: Initialising a scanning ultrasonic sensor

Your robot sounds very much like one of the first ones that I made when I got a NXT a number of years ago. I had the ultrasonic look left and right to see what was around. If something was close, it would go that direction. I just opted to make sure it started centered and then always returned to ce...

Re: Read/Write over Bluetooth in Ev3?

In the doxygen docs created from the lms2012 source code, it explains the communication protocol. It is not complete, but enough to get you started. Also, you won't be able to do it from a terminal to the COM port. The messages are binary, not text and each message must fit in a single bluetooth pac...

Countdown to EV3 - The Mindstorms Alarm Clock Sensor

Hello robot-heads, My NXT has been gathering dust for the last year, but news of the EV3 has got me really excited about it again. In anticipation, I have turned a LEGO Star Wars alarm clock into a Mindstorms sensor to countdown the days until the EV3 is officially released on the first of September...
