I can finally disassemble this , my first "complex" MOC with instructions. At first I thought to do a specific dumper, a white liebherr, but at the end I did a generic truck because I didn´t want uncommon pieces and I wanted to use less room as I can. Everything is in the vid, is a simple MOC, very tight but simple I think. You can see the construction post here - http://www.eurobricks.com/forum/index.php?showtopic=112319&st=0 . I hope you like it. http://www.youtube.com/watch?v=e3BMUcXSgqU&feature=youtu.be '>http://http://www.youtube.com/watch?v=otIHXDS_dS0&feature=youtu.be -
Hi! Some days ago, I created this autovalve: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=534632 My goal was to keep it small and reliable. If there is something, which can be build in a lot of variation, that's the autovalve. (If you don't know what it is: autovalves are made to remote control the pneumatic valves, the motor switches also the valve during making pressure with the compressor. The valve's position depends on the motor's turning direction) I needed as small autovalve as possible, and I also wanted to make something own. This one never can get stuck, I think this is the most important. Some other ones, I tried out, sometimes get stuck when I wanted to start them again or when they reached a special position. For working properly, it requires strong black pins ( http://www.brickshelf.com/cgi-bin/gallery.cgi?i=5955002 ; or the very old ones in 8842) if the valve is new, and hard to move it's lever. The pictures tell the working principle, I tried to make it very simple. The worm gear moves the 8t gear which is built together with the valve lever. The worm gear "ends", when the lever reaches one of the two final positions. The other 8t gear with the blue pin is for going backwards. Sometimes it doesn't needed, but without that it wouldn't be 100% reliable. There is a difference also between the blue pins, so if you choose well, it requires absolutely minimum power to turn.

Hi! Didn't know this forum, pretty awesome! I want to show you my technic robots that I've built so far. Since I'm from the early 80's, I never got used to building with studless (although I see some advantages) so forgive me: the robots are all studded ;) Next to that: I love electronics and I love to design it myself so I'm using the Arduino platform instead of NXT to control my robots. For me it's more flexible (and cheaper). Plant watering robot This was an idea of a colleaque of mine when I was telling that I was building an autonomous rover (see below). He said to me: why don't you build something useful like a robot that takes care of the plants while you're on holiday! And an idea was born... See below the result :) Autonomous rover which returns to a charging station when battery runs low This one was a real hassle to get it work. The rover itself wasn't the problem, but to make it park into the charging station was tricky. But I pulled it off by a coded IR signal which tells the rover when to turn and drive into the station. It's built in a Classic Space theme with cool lights. Oh, and in the end of the video, the rover takes care of some evil space pirates ;) Light chasing autonomous rover Predecessor of the rover above: driven by NXT motors it was a "real rover" with wheels. Unfortunately it wasn't agile enough to make it park into a charging station...
