The Brick adapters seem to work best with full snaps on the end. That is, having one-sided snaps on each end (i.e. power or bitSnaps), creating full snap pegs on both sides, rather than half pegs at either end. The components I have tried with just half snaps on an end (e.g. Power and a Motor, see pic) don’t seem to have the inside grip to hold well. Photographs showing difference:
I just noticed this is also discussed in the “Provide Extra Support for littleBits that Experience Force” section of Tips & Tricks: littleBits + Lego®, linked here:
Of the suggestions, the bitSnaps route seems the way to go (dissasembling a wire module?! no). However, it is odd to require additional pieces to make the adapters work well. This isn’t an issue just with torque or heavy components. Both sides of the adapter are fairly loose (compared to LEGO’s tight fit). It would be nice to have “bitEndCaps” created & included with the adapters. Also, the tolerances could be tighter all around, since even with flanking components the littleBits seem to pop off adapters easier than with Mounting Boards.
One last request, since this has gone in that direction. Could we also have some reversed blocks for using Mounting Boards? Currently only the LEGO side is offered in both orientations. LEGO plates are nice, but I would like the option to pick and choose. It might also be less confusing, and less have less flex, if the littleBits side looked more like the Mounting Board. Currently it has peg outlines rather than the more solid surface of the board.
In support of Mounting Boards, I will provide an example in both Mounting Board and LEGO. This image below shows two Mounting Boards sandwiched back to back, and gaffed. The LEGO front is simply gaff taped to the boards. The extra power leads were for motor flanking, but not needed if you plan on taping. More pics on next post, since I am currently limited to 3.
Optical sensor build details, by JackANDJude, can be found here:
The underside of this build also has the motors gaff taped, with 1" strips across the power connects in and out, for added strength. Taping adapters like this would be tougher I believe, since you would be blocking the other side. I will try a couple options though and post results. Using a similar sized LEGO plate with adapters should work. Especially if I can keep the tape off the opposite side of the plate (possibly just pinch it at each edge with blocks). I’ll see if I can’t find the correct sized LEGO plate later today. One small thing to mention, is that this will change the side to side spacing a little. I’ve noticed that the adapters are built to have space between them.
