[MINI] D3K's WIP topic
Rockbrick replied to D3K's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
super little thing - don't think I will bother entering .... -
[WIP] C4 Corvette
Rockbrick replied to timslegos's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I think you should use ball joints and respective 6L rod instead of the red studded beam as there will be sideways movement due to the 4Ls on the other side - the longer those would be the more close to vertical their arc would be (see panhard rod design and implementation) -
Shopping for Lego bargains ... in Berlin
Rockbrick replied to DrJB's topic in General LEGO Discussion
KaDeWe is a must anyway (if only for the food hall on the top floor) - and its not far from the lego shop and if you are near the zoo - eat here: http://www.zurkneipe.de/ though anywhere in the area are some great eating houses -
Spybotics: now
Rockbrick replied to system's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
should be no problem getting a very cheap latpop with a serial port on it running windows xp or earlier -
use something like this in the centre drive shaft but with one side 'locked' all the time (for the rear wheels) then you can use a selector to also engage the front axle or not then using the larger ring or smaller ring you can achieve low or high ratio - but would require another selector I can't see how to do that with just one selector at the moment

Half-Track Drivetrain
Rockbrick replied to Tommy Styrvoky's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I always wondered why half tracks were called 'Kegresse' a quick wikipedia lookup and now I know and want to share with you that Adolphe Kégresse was a French military engineer, inventor of the half-track and the dual-clutch transmission. Worked for Tsar Nicholas and Citroen. -
Super-Strut Suspension
Rockbrick replied to hamster_lego's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Please feel free to make changes - it does need improving - its just something I came up with quickly....move the lower arm out a bit, the top ones in, mount it at an angle etc... you won't learn something if its given to you on a plate - take it apart - improve it.... learn it -
Super-Strut Suspension
Rockbrick replied to hamster_lego's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
yes its steerable for ackerman change the design as you please.... gives good ground clearance but not too much travel though. -
Super-Strut Suspension
Rockbrick replied to hamster_lego's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
have a look at the front of the subaru wrx that was on here recently I played around with this recently and could be quite close to centrepoint steering if you use a large enough wheel hub (but technic wheels tend to have 'unkind' offsets for this -
Motorbike

sure looks nicer than my attempt at the 8260 alternative model -
Volkswagen Beetle (Type 1)
Rockbrick replied to Sheepo's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
nice to see a 'small' car (with a big heart) from Sheepo.... well done dude - the correct front suspension is a joy to see but please get one of these for your gearbox stickers.... I have one and its great for MOC stickers http://www.amazon.co.uk/Polaroid-Digital-Photo-Printer-Technology/dp/B001APNVTQ -
bad mocs are just prototypes - proof of concepts that work or dont work - thats how we learn to make better mocs I made a 4WS version of 8865 - with a gearbox on the steering that enable full 4WS, Crawl mode and 'Honda Prelude' mode (slight steer at the rear) because I couldn't afford 8880 - it looked and drove awful and the steering arms kept falling off at the back

was always into technic... For me it was when I left home to go to University in another country up until my kids were old enough to be interested in lego (luckily very soon in their lives) - this was around the early mid-1990s when the 8880 throguh to 8421 came out which I would have bought for sure... but as I was at university in another country to mine travelling back and forth buying large lego was out of the question (still got some small sets) I grew out of it but still ocasionally played with my really old technic sets. the dark ages really came when I discovered classic cars and watch repair and spent more time taking watch movements apart and real cars instead having then had kids eventually brought me back - has taken me a while to get used to studless design my brain still thinks in studs

Axle Collection Thread
Rockbrick replied to efferman's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
an idea I tried for front suspension: (looks rubbish in LDD but I tried in real life and all clicks and fits into place ok....) -
performance is pretty good with the Lego Li-po battery but partly due to the weight saving too I only recently bought a rechargeable box to try on the 9398 previously with the large battery box I use 1.2v rechargeables anyway so the voltage is very similar though with 6 new 1.5v alkalines ts goes great but not for long as you will waste them wanting to play with it all the time...

sheepos truck is amazing - clever use of height correctors.... i don't think anyone can ever top this - one should stick to the 8297 method of height adjustment its very compact and does the job
