  1. Watch out for DBG technic parts with brown stains .... for sale on eBay. If you can't pass up the deal, they must sanitized!
  2. 9 pages and not a single picture??? Speculation (and wishful thinking) has become the rule-of-the-land in this forum
  3. I've been wanting to setup a dedicated home computer for my EV3/NXT bricks, and with the cheap (and small foot-print) RPI, this sounds very appealing. Now, after some googling I found ev3dev but my understanding is that it's a whole different development environment. I ultimately want the same EV3 environment as that on a windows machine. Anyone knows how to achieve this or if anything is in the works?
  4. Except that in Bricklink, the parts' IDs for flex axles are NOT the same ...
  5. That is why, if you buy old sets from eBay, the first thing you need to do is sanitize/disinfect/wash thoroughly .... :)
  6. Try to look up a thread I started a while back, called 'nails & glue'. I came up with a similar conclusion that, if you add all pins, and bushings, the number is sometimes higher than 1/3 rd.
  7. Glad you found a solution to the issue you identified earlier. People in Robotics would tell you that the initial mechanism was not valid because it has a singularity in its Jacobian Matrix ... If I recall correctly, I think Akiyuki used gears to link the motions of the various axles, though I can't locate the video now.
  8. Fully agree with this. Would be nice to have an EB contest where no wheels/tires are allowed!
  9. Reminds me of a Meccano humanoid, that came out only few months ago. Though it does not have the same 'flexibility' as building with Lego, it has a promising 'brick' and 4 servos ... and you can get it on sale at some Walmart stores for barely $40. http://www.amazon.co...s=meccano robot
  10. I saw them a while back, though I felt that, at $1.00 a piece, they were rather expensive, especially that they were plain orange and no added cost due to printing (as for the soccer/football balls).
  11. Yesterday I took the kids to this yearly event, and there, almost everyone was carrying these white and blue brickloot boxes. Apparently, if you had bought your tickets through groupon, you get one free box. Brick-Loot also had a display area where they were selling such blue boxes for $25, claiming a value of $40.00. After getting home, we opened the box, and granted, there were 4 mini sets in there. One was made with genuine lego parts, all other 3 were cheap china-made replicas. Needless to say I was very disappointed, as the value to me was $5-10 at most. How can a company such as this be admitted in an 'official' Lego venue, and be allowed to make $$$ off 'unsuspecting' lego fans? This is simply unacceptable, and a shame to the organizers!
  12. For those interested, BrickWorld Chicago is taking place this weekend, at the usual location (Renaissance Schaumburg)
  13. Thanks. I just downloaded the MPD. You guys are fast!!!
  14. Near 2:50, there is a module called 'Wheel & Steps', and I do not recall seeing that in the past from Akiyuki. Of course, there were other similar contraptions by others, but it's the first time (I see) an Akiyuki version.
  15. I like it a lot! I have many of those buckets (50+) and been contemplating building something similar, as in LDD renders below. Note that the bucket per say is not available in LDD, and hence, the use of 'generic' parts.
