    Making the valve body a through hole is good. It could then easily be drilled/reamed to provide a better surface. Stackable is great, but could the connector be thin so you could attach a thin lift arm and keep the stack tight? Great work again

    Very nice indeed

    Awesome mini. Well done

    Fantastic. Looking forward to seeing how they go :)

    Finally got around to sketching it out in LDD. Green gear and shaft is standard, so is red. Orange and yellow are the proposed compound gears (without cross hole) running freely on the shaft. What do you think?

    I was just scanning through looking at the history of awesome parts and stumbled across this post. Efferman I think you have me confused with someone else. I've not had anything to do with the Torsten diffs. Cheers.

    Great model. Nice work in such a short build time too :)

    Thanks, good to know.

    On top of the drawers and containers mentioned, I also use a dump tray about 40cm by 30cm. It saves having to sort back to individual compartments when prototyping. About once a week it all gets sorted back into the proper storage containers.

    Are these the standards you are referring to? http://www.teamhassenplug.org/GBC/ Or was something released by TLG themselves (which I can't find reference to) and this is a derivative? Cheers.

    Must have. Thanks for the great review Jim.

    I've wanted these for ages! Sweet, thanks for the heads up.

    I can add to the suggestions of placing a dummy load across the 5V output to keep the 12 happy. Caused a lot of head scratching when I found it by mistake a while ago! A big chunky wire-wound resistor 5.6(ohms) capable of 5W should do the trick.

    Thanks, missed it when I looked through before.

    How about free-wheeling pulleys so you can make a 3 or 5 stage pulley system for hoisting crane hooks? They could all be mounted on the same axle and turn at their own rates without the string having to slip over them. I had a look through you shapeways store. There are a lot of cool parts there :)

    That looks awesome. Functions?

    Bricklinking the missing parts from 8865 did it for me. I bought the front end suspension/steering parts via lego service in the 90s but never built it up properly in its own right. Then after ebaying 8868 there was no going back.

    I'm using old school studded beams in my current project to achieve a particular look while maintaining rigidity. Also using a number of old style pneumatics but only because I wanted the clear cylinders, it could have been the new style. All PF and NXT motors, no old 9V here. Mainly because the PF are so compact I guess. As for the old gears, that depends solely on where it has to go and what it has to do :) I don't use the old style small bevel gears anymore. The newer ones are so much better. Looking at a classic build of you own? *edit Whoops completely missed second part of OP. How much you got?

    They both look really good. Do you think the free running 8z would now be strong enough to make a compound sprocket with a 24z? You could then build high ratio gear trains on just two axles without resorting to worm gears. Especially now TLG is releasing axles with round portions specifically to reduce friction/wear on idlers. Keep up the good work.
  20. OzShan
    I'd have that on my shelf

    I see they haven't used the logo anywhere but surely the pf connector is proprietary? There have been a few home brew projects like this and I wish TLG would pick it up because it would expand the mindstorms platform very nicely. Much more useful than the IR-link.

    Great build. You categorised the original perfectly. You either had it or wanted it. I wanted it and this is a great modern effort :)
  23. OzShan
    There is also nothing stopping you from using the outside gear as the stator, and the flex spline as the output. It would give higher compactness in this application as the outer gear could be built to extend back and hold the motor directly and be used to mount the whole assembly. While compatibility with other gears is great, bear in mind that the percentage deflection relative to the radius of the flex spline is very small on full size drives. Using deep full size teeth on such a small diameter flex spline will introduce a high wall angle as the spline deflects and flares out.
  24. OzShan
    Yeah, why not. I think diameter is not the main issue if you can keep it short/thin. i.e compact enough to mount under a turret or crane turntable etc :) Maybe have the output the same as the large turntable and it would drop into a lot of projects more readily?
  25. OzShan
    That looks awesome! Instantly recognisable as a flex spline :)
