Best way to host an image?

We have a modified version of Raspbian that works with the BrickPi and some of the other products we make. For a while, we hosted it for download on Google Docs. We just tried Sourceforge as well. However, in both cases, a few users have complained that the zip file has been corrupted. http://source...

Re: Help with BrickPi Please!

@DeeJay

Did I forget a sudo in there? Would this be a more constructive command?

Code: Select all

sudo apt-get install python-setuptools

Re: Help with BrickPi Please!

Hello Cubanbejar, This is a little confusing, a few questions: Did you clone the entire BrickPi_Python Directory? The example programs reference a file called "BrickPi.py" that has the drivers for communicating with the BrickPi. Also, this has tripped a few people up. To install the python module, b...

Re: BrickPi

Hey Jack, and all! Thanks for bringing this up, I think I have a solution: Run apt-get install python-setuptools and then run sudo python setup.py install I think that setuptools is not a standard install on Raspbian, and this causes the failure. Can you let us know if that solves the problem? :D We...

Re: BrickPi: LEGO NXT and Raspberry Pi

Hey plugwash, Great points all around. What you're seeing on Github is a first, alpha version. We've pushed a newer version that we've tested, and found works great with both analog and digital Mindstorms sensors. We're still collecting some feedback (so thanks for your feedback on the design) from ...

BrickPi: LEGO NXT and Raspberry Pi

We just launched our first Kickstarter to fund the BrickPi. The BrickPi connects the Raspberry Pi with LEGO motors and sensors, and has a custom case that allows you to attach LEGO's to the Raspberry Pi and build out your robot. We've already succesfully funded the project, but we could really use a...

We're working on it. It can be pretty accurate, but we're trying to improve it.

We've updated the whole thing and started a project here:

This was super-helpful. Thank you for sharing the code! I've been beating my head against the wall for the past day trying to figure out why I couldn't get 6 bytes of data back. Thanks for sharing your code!

Simon, Thanks. That's really interesting, and 20 lb seems reasonable. So one more question for you: this project has been using i2c to communicate to the sensors and I'm pondering serial to do a faster job. I see you've got some experience in Scratch. I know nothing about it but I'm curious if there...

Re: LEGO-pi brick

Thanks for the great advice! That's really cool actually, I'll think about how we can connect those up, the old RCX? Does that marry up with the WeDo? I have some WeDo laying around. We were just doing this as an experiment to see if anyone was interested in it. It was a lot of fun, and I think we'r...

Re: Controling Lego DC motors

This is a project we started working on with LEGO motors and sensors. It's not totally complete, but the hardware and firmware is complete (we could use some more work cleaning up our python code). This connects the LEGO motors and sensors to the Raspberry Pi. http://www.dexterindustries.com/BrickPi...

Hello, We recently started a project that does something similar.

Re: Changing SPI LSB order

So I couldn't find a way to do it in hardware. I saw some posts out there that said that reversing the bit order on SPI wasn't possible on the RPi, so I went the software route. Below is a function I found that reverses the bit order on a byte. There are bit-by-bit methods, this was supposed to be t...

Re: Changing SPI LSB order

Just a quick update, I'm making a little bit of progress on this. I've written some code that, in software, reverses the bit order. It would be nice if this could be done in hardware though!

Re: Raspberry Pi and LEGO MINDSTORMS Motors

The chip doesn't seem to get hot. Because it's DIP and can handle up to 1A, I think it's pretty well designed for the product.

Hey folks! I'm working on an SPI project. My hardware, a PS2 controller, requires the LSB to be first. It seems the RPi default though is LSB last.
