The caddy started life as a regular 1983 VW pickup. Unfortunately, the years had not been kind to it. The body panels were in good shape, but there were serious rust problems in the floors, strut towers, rockers, and control arm mounts. According to [RC6015], this is beyond “weld on few replacement panels”, though he’s been heavily questioned on it in his Reddit thread.
Cutting the truck down was easy – a reciprocating saw did most of the work. The VW has a unibody design, so there was still some frame there to hold things together. A 2×12 board then was then bolted from the front of the truck to the rear. This made everything stable and provided a solid mounting point. A second 2×12 was lag bolted to several studs on the wall. Then it was just a matter of lifting the truck into position and bolting the two boards together. We’re guessing the [RC6015]’s wall has solid wood studs. Don’t try hanging a 500 lb truck from the wall if you’ve only got thin metal studs behind your sheetrock.
Just in case you’re wondering, the Panasonic Model RC-6015 is a vintage flip display alarm clock, the same one Marty used in Back to the Future.
At least that’s the approach that [Tom Stanton] took to his electric bike build. Having caught the electric locomotion bug on a recent longboard build, [Tom] undertook the upgrade of a cheap “fixie,” or fixed-gear bike. His delta printer was big enough for the motor mount and weather-resistant ESC enclosure, but he needed to print the drive pulley in four quadrants that were later glued together. We can’t say we hold much faith in the zip ties that transmit all the torque through the rear wheel’s spokes, but as a proof of concept it seems sturdy enough. With a throttle from an electric scooter and a battery in a saddle bag, the bike turns in pretty decent performance — at least after a minor gearing change. And everything blends in or accents the black frame of the bike, so it’s a good-looking build to boot.
Everyone must have a few things that are emotive of their childhood, perhaps a sight, a sound, or a smell. For me, growing up as I did on a small British organic farm in the 1970s, my emotive things are the smell of rain hitting parched earth, or of the slightly sulphurous diesel exhaust from a clapped-out Fordson Major tractor. And wheelbarrows, strangely. My dad, you see, is both a blacksmith by trade and an inveterate experimenter in the field of handcarts and barrows. A small self-sufficient farm generates a huge range of different loads that need carrying around, and he fashioned a variety of inventive contraptions for the purpose. Of most use are his oversized builder’s barrows with a full-size van wheel at the front and able to cross the bumpiest of ground, but other highlights included the low-loading barrow for shifting the heaviest one-piece loads, or the two-wheeler for very long objects.
As you might expect then, I have an eye for a barrow, as I’ve pushed a few in my time. So when I read about how traditional Chinese barrows are constructed, they caught my attention and I had to ask: why don’t we do it that way?
In a bit of punky, steam-based tinkering, Brittish engineer [Geoff Hudspith]’s obsession for steam and passion for cycles fused into the Hudspith Steam Bicycle.
Built and improved over the past thirty years, the custom steam engine uses a petrol and kerosene mix for fuel, reaching a top speed of 32km/h and has a range of 16km on one tank of water. While in motion, the boiler is counter-balanced by the water tank on the rear as well as the flywheel, water pump, and the other components. However, [Hudspith] says he doesn’t have an easy go of it carrying the bike up the flight of stairs to his flat — as you can imagine. A steam whistle was fitted to the bike after insistence from others — and perhaps for safety’s sake as well, since it does take a bit of distance to stop the bike.
Many people have offered large sums for it — and at least one house in exchange for the bike — but [Hudspith] has held on to this one-of-a-kind steam-machine. A little more about the development of the bicycle can be read here! A video of the bike in action is waiting after the break.
Ok, there are some worthy laws in place regulating the sale and distribution of alcohol — and for good reason. For many a bootlegger, however, the dream of renovating an old trailer from 1946 into a mobile bar is a dream that must– wait, what? That already exists?
It’s no mobile workshop, but the bar was initially built to accommodate guests at their wedding. [HelloPennyBar] has shared the reconstruction process with the world. Inside, there’s everything you’d need to serve beverages, including a (double) kitchen sink. In addition to a water tank, a pair of car batteries serve as the central power with electrical work installed for interior lights, a small fan to keep the bartenders cool, exterior lights, a water pump, the trailer lights, and more exterior lights so the patrons can party the night away.
Before you say anything, [HelloPennyBar] says they would need a license to sell alcohol, but alleges that for serving alcohol at private events in their state it suffices to have an off-site responsible serving license. Furthermore, a few helpful redditors have chimed in regarding battery safety and cable-mounts, to which [HelloPennyBar] was amenable. Safety and legality noted, the mobile bar must make for a novel evening of fun.
Hacker dads often have great plans for all the fun projects they’ll build for their kids. Reality often intrudes, though, creating opportunities for hacker grandfathers who might have more time and resources to tackle the truly epic kid hacks. Take, for instance, [rwreagan] and the quarter-scale model railroad he built for his granddaughter.
Taking inspiration from a 1965 issue of Popular Mechanics, grandpa hit this one out of the park. Attention to detail and craftsmanship are evident from the cowcatcher to the rear coupler of this 4-2-0 steam engine replica, and everywhere along the 275 feet of wooden track — that’s almost a quarter-mile at scale. The locomotive runs on composite wood and metal flanged wheels powered by pair of 350-watt motors and some 12-volt batteries; alas, no steam. The loco winds around [rwreagan]’s yard through a right-of-way cut into the woods and into a custom-built engine house that’ll make a great playhouse. And there are even Arduino-controlled crossbucks at the grade crossing he uses for his tractor on lawn mowing days.
The only question here is: will his granddaughter have as much fun using it as he had building it? We’ll guess yes because it looks like a blast all around. Other awesome dad builds we’ve covered include this backyard roller coaster and a rocketship treehouse.
In the world of sailing, there are many records to compete over. Speed records, endurance records, size records. The fastest crossing, the longest solo journey, the largest yacht.
But not all records concern superlatives, for example in the size stakes, there are also records for the smallest vessels. The Atlantic crossing has been completed by a succession of ever smaller boats over the years, and the current record from 1993 is held by the 5’4″ (1.626m) boat Father’s Day.
Records are made to be broken, and there is now a challenger to the crown in the form of the impossibly tiny 42″ (1.067m) Undaunted, the creation of [Matt Kent], who intends to sail the boat from the Canary Islands to the USA in around 4 months.
The boat’s design is definitely unusual, with a square aluminium hull of equal beam and length, and a very deep keel that has an emergency drinking water tank as its ballast. The sail is a square rig — imagine picture-book images of Viking ships for a minute — and it has two rudders. We are not nautical engineers here at Hackaday, but reading the descriptions of the boat we understand it to have more in common with a buoy in the way it handles than it does with a sleek racing yacht.
Unfortunately the first sailing attempt suffered a setback due to a design flaw in the way the vessel’s emergency flotation is attached. This was revealed by its interaction with some unusual waves. But [Matt] will be back for another try, and with luck we’ll see him on our TV screens sometime next year as he emerges into the Florida sunshine from his cramped quarters. Meanwhile his unusual boat and its construction makes for a fascinating read that we’re sure you’ll appreciate.
