    Sorry I missed that, The NSx is partially dismantled so I can not tell you but I all comes froms the GTB fiorano 8145 lego. My new creation (small one) for halloween : A small creation for halloween : the lighning halloween monster. For marking the occasion, I have decided some weeks ago to build a special creation for halloween. I wanted to create a pumpkin in lego with lights in it but not figure out to build correct shape with the orange parts I have. Therefore, I have decided to build a lighting sculpture of a monster. There are two Led Lights from lego (so 4 LED), which is connected to the lipo battery. Then, I put on other motor and battery to make alternately rotate the control of power of the light, in order to have a alive effect. The principal difficulty was to obtain the correct shape on the mouth and the eye especially in the dark. Then I uses translucent red parts for the teeth because with black one, there was not enough light power to have a good effect. Regarding the result I think I would need a other light on the center to have a complete and proper mouth illumination. The second important point was to avoid light leak because if there is, the viewing result will not be good. That I do by making a box around the light to prevent leak and add a black flat panel on the rear in order to limit the light reflection on the background. The result is not perfect but this is lego technic, not system, so I can not make full dark boxes. The effect is still conclusive by displaying at the Halloween night and have some good returns.

    Hello, thank you for the comments, I am glad that you apreciate. For the topic, I prefer one because I do not pass many time on EB forum. That is simplier for me. Yes very lucky to drive a NSX, but thanks to a Fan of lego who own one, but thanks to lego because it contact me for my Honda RA300 :)

    A write the whole story of that moc on my blog so I copy paste here, I hope you enjoy :) A reproduction of an iconic car from the 90’s : the honda NSX type 1 featured V6 fake engine with rear wheel drive, steering with steering wheel, double wishbone suspensions, pop-up headlight, opening doors, hood, trunk and rear glass roof, and adjustable seats. The story of this project I am a big fan of Honda (no really ?), but it is not a big deal, I am trying to cure myself.. by buying Honda car and motorcycle. I own a 89′ Transalp, and recently a Honda legend Ka8, but having a NSX is still not in my budget ! So I planned a long time ago to make one in lego. In beginning of 2017, a fan of lego and honda named Elvis, contacted me for questions about the Honda Ra300 I made in lego. Following some discussions about Lego and Honda, I discovered that he ownes the legendary Honda NSX. After that we met in order that I give him some parts to finish his Honda RA300 and it gives me the opportunity to see in real the NSX, take detailed pictures and drive it ! Then, I decided to make the NSX in lego. Engineering I have started to use the 53mm wheel instead of big 68mm because of the scale and the result in quantity of parts. I think it is a good scale for manual car. Then I started with the chassis, trans-axle, and finished by the bodywork. The reproduction of the NSX in lego is equipped with full suspensions, as double wishbone inspired by the Groupe B Rally Car. The trans-axle is a rear wheel drive, due to the scale it is always complicated to have wheel drive and double wishbone suspensions. On the Group B rally car I used soft ribbed hose to connected the wheel to the differential, because these parts are 2-stud wide, instead of the 3L U-join but it works only by friction, excluding motorization. But for the NSX, I figured out to find an other way. I use in fact a floating differential enables me to not use U-joint for the axle, only Cv-join connected to the wheel hub. For that I use a 4L old differential which drives couple of 16t gear, and then 24t/12t to drive the V6 engine. Of course at this scale this is not possible to have a gearbox, or with removing the detailed of the interior which I did not want. The steering is classical made with rack and pinion on the front, with an axle for the hand of god (which is by the way removable) and an other with a gearing and 2 U-join to operate the steering wheel in the interior. The pop-up headlight are operated by a lever in the dashboard. This lever drives a connectig rod which is also connected to a lever. And this lever command the displacement of the headlight by pushing the base, which causes the small rotation of them. It was a bit tricky to pass the whole connecting rod and system in it but it works fine and can be operated from the interior which was important for me. Design The design was of course the most difficult part to do. It was also the most important ! Because the Honda in lego need to be realistic but also easy identifiable, that is why there are some interesting and important parts to reproduce, like the rear wings, the black roof, pop up headlight, shape of opening parts and so on. The only compromise that I did is for the doors, which do not respect the airflow intake shape. I started the design by the rear parts with the bumper, exhaust and rear wing. I wanted to reproduce the gap between the bodywork and the wing and use simple configuration of panels, which I did. Then I do the opening trunk and started to build the front. I made the front bumper, originally with more parts and more bulky but I restarted it by using some black parts to give the front bumper enough stiffness but also aggressive look. After that I build the black roof with the opening glass roof and the important C-pillars which are oblique. Then I finally make the windscreen and the opening hood and pop-up headlight. I have to restart many time to get the correct shape of this hood including the system for the headlight and have a correct opening shape, which was very difficult. You can see some holes without parts near the headlight, which is a compromise because of the room I have a steering wheels. You can see also on the video that I implement (at the end) a system to release the hood with a lever between the hood and windscreen. Then I finished the design by the doors, which have been also complicated because of the airflow shape. I would like to reproduce the thickness and the curving shape of the doors, and also include the airflow shape, which was not possible at the end. Maybe with bigger scale. But at the end, the shape is a bit here and there are also the two big airflow intake just after the doors before the wheel arch. I made the interior at the end, which was not complicated with the dashboard, central console, lever and parking lever. Then added two bucket seat thanks to many panel and made the adjustable position which is in fact a slidding connector on axle. Conclusion To conclude, I have tried many time to do the honda NSX in lego, but this time I started by the most difficult parts : the rear with the wings, and then build the other parts. Make the correct opening shape with the functions like pop-up headlight was complicated, that is why I have to do compromise (like the hole near the headlight, and the shape of the doors) but at the end, I am really happy with this car. On some views, the shape of the car is well done and respected, plus the distinctive parts like the wing, roof, and headlight make it easy identifiable. I could say that I find the front parts a bit bulky and more heavy in style that the rear, and some continuity problems of the panels near the doors (again for enabling the opening). But making lego scaling is always compromise to find the correct parts and assembly to fit, with good homogeneity and continuity, and respecting the functions ! I do my best for it and at final thing that the bodywork is rather successful.

    Hello, this is 150 to 230kv Xray generator which is made for view plastic and soft metal or strong metal until 20mm of depth. It is put in a leaded cabin. It is production machine we develope and produce except the generator and flatpanel which are bought. For the pictures, you can find it on my blog in high resolution. For the mechanism, I will. I am planing to pass small wind up motor, chinese parts, and axle. For converting the 3D, it is in fact many many point in aera (STL), the standard tomography is about 1go to 10go but the 3D will be exact and real part, that is to say that the surface are not flat and hole perpendicular like in theorical part in ldraw, therefore it could be difficult to implement in a construction because of that.

    New creations for christmas ! A lego interpretation of a 3 pendulums harmonograph drawing machine. Drawing machine always fascinated me, especially when they are fully mechanical. For instance a Spirograph is a mechanical drawing harmonograph, it simply not uses the same basic functioning to draw. The purpose of the harmonograph here is to draw Lissajous curves thanks to 3 pendulum connected to arm and felt pen. The basic functioning is : The main pendulum is a free ball joint articulated on the frame and hold up the drawing sheet The two other pendulums are simple way articulated which are connected together to the red arm This arms is built in 90° angle shape in order that it can move in one direction thanks to the first pendulum, and in other (90° of the previous one) thanks to the second pendulum A felt pen is attached to the red arm and draw on the drawing sheet To draw something, it needs only to launch one or two or three pendulum, therefore the system moves and draw something, especially geometric and continuous figures. Of course the result is always different depends of if you starts to move the main pendulum (give the main circular motion) and/or the two other (give the direction of circular motion and its evolution in time). And there are plenty of different harmonograph with more or less pendulum or connected pendulum or arms and so on. Here is the basic version of best known harmonograph. Note that the main red arm is equipped with counter weight at these ends in order to have the less friction of the felt pen of the drawing machine. That is why I use also a felt pen because of its low needed force to draw. Thanks to that, The felt pen is maintained in upper position and when the arm is push down, the felt pen maintains its low position with low friction. Nevertheless, the friction is still here and the weight of pendulum not as heavy as the real harmonograph (made in steel), so well that the main pendulum slowly tends to apply circular motion to the other pendulum which reduce the autonomy and drawing time (around 1 or 2 minutes). You can also see that I keep the idea of knife edge suspension for the pendulum from my Galileo clock. It enables to have very low friction and better Q factor on the pendulum (pendulum oscillate a long time). The main pendulum is built with two of this system in order to create a real ball joint articulation. You can note that the weight of main pendulum tend to taken apart one of the knife edge solution, need to improve it with technic brick instead of liftarm (which is of course better for rigidity but bad for compactness). To conclude, I am pretty happy to have made this piece of mechanical engineering, there are several important point to succeed to get that, regarding the weight of pendulum, rigidity of frame, main arm and pendulum (all parasite vibration will reduce the efficiency) and of course lot of test to understand which movements in the pendulum make final drawing. It is still always different and sometime unexpected ! See the gallery to watch it. :)
