Mad machinist masterpieces

If a picture is worth 1000 words, by our count, [Ryan Commbes] has said 1.68×10^6 different things about his custom robot, airsoft, and monster truck builds. While we’re not ones to pick favorites, we agreed his Alpine TPG-1 (picture at the top) build is a step above the rest. Sadly, the forums with his build log doesn’t seem to be loading, but he says the basic process if you wanted to make your own is to gather pictures, measure, and create.

Sukhoi Su-27 Jet build throws down

This no model, but a fully functioning RC jet. The Sukhoi Su-27 was the Soviet Union’s counterpart of the F15 and this 1/6.5 scaled version measures eleven feet long and is fully controllable. As if the 80-page build log wasn’t enough, the flight video after the break is nothing short of jaw-dropping. The test flights end in smooth landings but with all the time that went into the project that’s got to be nerve-wracking.

Amazing chassis hacks

[Crabfu] pulled off some great chassis work on top of a remote control drivetrain. His most recent build turns the tiny traveler into a lunar rover complete with passenger and a communications array. For this he’s sourced the parts from a toy but boosted the realism with hand-painted details that leave us in awe. His previous project sourced the body from a model truck kit. Once again, it’s the paint work that makes us envious of his skills.

Both projects conceal a Losi 1/24 scale micro rock crawler that provides for some incredible locomotion. See video of both builds after the break.

Double clutch transmission model

[Alan] did an extraordinary job building a computer controlled model gearbox. His project from several years back is based on a dual-clutch Direct Shift Gearbox that was developed for VW and Audi vehicles. His design uses a gear head motor to provide the locomotion to this transmission. Shifting is computer controlled through serial cable, with servo motors providing the physical motion to change gears. Seeing all these moving parts in the clip after the break might make you a bit dizzy.

This is some extreme model building. It reminds us of the guy who built that aluminum aircraft model that was all over the Internets in December.

Desktop Decepticon repurposes cell phone

cell-phone-decipticon

We’ve got a few old cell phones sitting around and apart from salvaging the LCD screen we’re not quite sure what to do with them. [Gingerpete50] turned his into a desktop Decepticon figurine. This masterpiece is a delightful conversation piece and when he’s tired of it decorating his cubicle, we’re sure there will be plenty of people he can hand it down to. The figure doesn’t transform back into a cell phone and it uses a few extra parts he had on hand, but neither of these things bother us. What it does have is some articulated joints and a few LEDs that you can see above. We haven’t tried our hand at custom model building, but after seeing this you can be assured it’s on our list.

1:35,200 Scale Train is World’s Smallest

nanotrain

This train layout is so small it nearly defies photography as much as it defies expectations. Built by model railroad enthusiast [David Smith], this is a model of a model: an N scale (1:160) layout inside a Z scale (1:220) world! For size reference, the entire layout is shown under a ballpoint pen tip in the photo above. And it actually runs!

Of course with this being Hack a Day you know there’s going to be some shenanigans involved. Pause the hi-def YouTube video at the 0:50 mark and see if you can puzzle it out first. The remainder of the video and [David’s] project page reveal how this all works, and it’s no less amazing even with the trick exposed. Check out his other ludicrously small mechanical wonders as well!
