Pneumatic Autovalve - non clicking
Pvdb replied to Pvdb's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
In this mock-up model I just put the compressor on in the quickest easiest way possible, there is not much travel running it off the 24 tooth gear. If you set the compressor up using similar method to unimog then you will get more travel. -

If you build it then you need to make sure that the top worm screw is set to the correct orientation so that it meshes smoothly when the bottom screw slides accross to collect it. Perhaps this needs a photo - will do that tonight - otherwise just test all 4 possible orientations to find the best one LDraw file is on Brickshelf -

You perhaps didn't finish reading my post??? -

The point is that the motor is never stalled as with some of the other designs. Thus you can run a compressor from the same motor, and you don't ruin the motor. -
I have been looking for an autovalve/compressor - and found one or two - the best in my opinion (as it doesn't run the rist of ruining the motor) and most compact by Sariel quite a few years ago. But it clicks - click click click click - and it is virtually impossible to return the valve to neutral. Not sure if anyone else has done an upgrade so I wondered if I could improve on it. Here is the result and it seems to work very well. It doesn't click, and it is possible to stop the valve at neutral. There is still the slight delay in the valve changing, but the delay is shorter than the time it takes to walk across the room to manually switch the valve This model is a stand alone version with a bulky frame, it can be really compacted a lot - as I have just done in my next MOC. I should mention that the top worm screw is on a fixed axle

I am amazed how fast you make progress. Looks great so far -

Nice job on the car. Looks good -
Since you ask for an opinion, I would say that in this particular context, I think that you should be flattered rather than upset. Perhaps the ebay seller could have added some attribution. In fact, a link to your website may have helped ther sellers cause since this would have perhaps re-inforced the validity of the text. It would be very different if someone set up a similar website to yours and then started copying your text.

Need ideas for a gearbox.
Pvdb replied to darkboy101089's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Copy and Paste it all into Notepad, then save as Gearbox.ldr You should then be able to load that into LDraw -

Here is the LDD file http://www.brickshelf.com/gallery/PvdB/Koenigsegg/koenigsegg_ccx_-_sequential_gearbox.ldr It has some of the Koenigsegg Chassis around it, just strip it down in LDraw. Have Fun -
Need ideas for a gearbox.
Pvdb replied to darkboy101089's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I came up with a better gear change rachet mechanism for my Koenigsegg that I have just finished, by turning the gearbox over, this can all be kept as low as possible in the chassis. Nice work on yours so far though. -
I partially agree and that is why my recent Koenigsegg has no batteries in it, but some of the remote controlled power funtions supercars are impressive in their own right whether or not they drive well, Sheepo's Bugatti for example. And there are a few cars made with the true 'radio control' buggy motors that do run well, the Tumbler and the Zonda by Sariel for example. http://sariel.pl/2012/09/pagani-zonda/ .

Very Nice Engine to go with the ship. -
Koenigsegg CCX almost completed
Pvdb replied to Pvdb's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I have almost finished the CAD, there a few things to finish off in the model. I never made actual instructions before, I could consider it though. -
Koenigsegg CCX almost completed
Pvdb replied to Pvdb's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Cheers. As for a 7 speed gearbox, there would be space for the actual gears, but with this design, the more gears, the longer the selector arm has to be that slides back and forwards, this was the limiting factor My first stand-alone version of this type of gearbox is on MOC pages http://www.mocpages.com/moc.php/239686 including Ldraw file so you should be able to build it from that (you can see how long ago it was that I first started with the idea of building a supercar!!!) For the Koenigsegg, I adapted the sprung selectors to make them more compact both horizontally and vertically and thus reducing the length of the selector arm (you can see in the picture & those bands need to be quite taught) I also went for a different (and I think much better) gear stick ratchet mechanism, and of course adapted the housing a bit to fit into the chassis -

Hi, I added a few more CAD images including one of the bottom - not quite complete yet but gives the idea. -

Pvdb replied to Pvdb's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Cheers. Took me while to figure it out. I added a white band (just visible in the photo) to tighten up the mechanism a bit. Still have to add that part to the cad -
Since it has been years in the making, and is so close to being finished, I thought I would put up some images of my new Koenigsegg CCX inspired supercar. It features: Improved version of the 5+N+R sequential gearbox that I created several years ago in hope that some day I might put a supercar around it!!! Technic engine driven by Rear Wheels Double wish bone suspension front and rear Brakes front and rear Optional HOG steering, My version of the Koenigsegg Syncro-Dihedral door hinges opened/powered by the Sprung Dampers (these open pretty smoothly) Opening Engine cover opened/powered by the Sprung Dampers Opening Bonnet Adjustable Seats Waiting to order a few more pieces, and getting there with the CAD file as well.http://www.brickshel...ry.cgi?f=522868 The Door Hinge The Gearbox

Never Ending Struggle?
Pvdb replied to Porty's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
This is an interesting topic for me. Rather than churn out hundreds of new models on a rolling basis (I donβt have time) I actually more enjoy reworking the few that I have made, take for example my helicopter which is now on its 5th iteration, each version including certain improvements. For me the aesthetics of the model are very important and the challenge is in getting the functionality in, and more importantly working well. My current version of Demag AC50 Crane, was the result of wanting to add more/different functionality and different looks onto the inspirational model by Jennifer Clark, but I know for sure that I am going to re-visit my model in the next few years β to take out or improve the crab/normal steer functionality I designed because although it works, it heavily reduces playability and has the tendency to go wrong, I also want to take out the non-lego actuators somehow and spring the suspension. Currently working on a large Koenigsegg CCX, maybe it will be finished in the next few months if I force myself along (started parts of it at least 2 if not more years ago), but I already have to stop myself re-designing the chassis slightly, Must finish the first version first!!!!!!! I think I am like many others though, i.e. all those who love modding and improving original lego technic offerings β I just prefer to start from my own base models in most cases.
