The renowned inventor of useless robots [Simone Giertz] has outdone herself this time. She, along with a team of engineers featuring [Rich Rebuilds], [Laura Kampf], and [Marcos Ramirez], recently decided to convert a Tesla into a pickup truck, and make a video along the way, all while salvaging what remains they can of the back of the car and making the final product roadworthy. Yeah, this is a couple weeks old now, and yeah, it’s kind of a commercial, but really: [Simone Giertz] and Co. rock.
In her vlog of the experience, the team starts by gutting out the interior of the car in order to find out the weight distribution and form of the outer frame. Essentially, in order to create the pickup truck, a portion of the back of the car needs to be removed, with additional beams and support welded in depending on the consequent structural integrity. With a sawzall and angle grinder, the top portion of the frame is cut and taken out, but not before a worrying glance brings about the realization that the car needs exterior support during its modifications.
After the cushions, glass, wiring, and all other accessories are removed, they install a truck bed from another sacrificial pickup truck, as well as a roof rack to complete the look. Amidst the deconstruction and reconstruction, there are moments when the car encounters a “Safety restraint system fault” or when the team accidentally lines the inside of the car with fiberglass right before shooting their video. Between complaints of the different clip sizes used and the clear time pressure of the project, it’s a funny and informative look into a pretty unique car mod.
The final commercial they made of their Tesla-pickup hybrid, dubbed Truckla, is available on [Giertz]’s YouTube channel.

It’s depressingly easy to make bad videos, but it only takes a little care to turn that around. After ample lighting and decent audio — and not shooting in portrait — perhaps the biggest improvements come from stabilizing the camera while it’s moving. Giving your viewers motion sickness is bad form, after all, and to smooth out those beauty shots, a camera slider can be a big help.
Not all camera sliders are built alike, though, and we must admit to being baffled while first watching [Rulof Maker]’s build of a smooth, synchronized pan and slide camera rig. We just couldn’t figure out how those gears were going to be put to use, but as the video below progresses, it becomes clear that this is an adjustable pantograph rig, and that [Rulof]’s eBay gears are intended to link the two sets of pantograph arms together. The arms are formed from threaded pipe and tee fittings with bearings pressed into them, which is a pretty clever construction technique that seems highly dependent on having the good fortune to find bearings with an interference fit into the threads. But still, [Rulof] makes it work, and with a little epoxy and a fair amount of finagling, he ends up with a complex linkage that yields the desired effects. And bonus points for being able to configure the motion with small adjustments to the camera bracket pivot points.
We saw a similar pantograph slider a few months back. That one was 3D-printed and linked with timing belts, but the principles are the same and the shots from both look great.

Wireless charging is great tech, but its relative novelty means it may not be everywhere you want it. When one of those places is your vehicle, well, you make like [Braxen McConnell] and crack it open to install a wireless charger!
After dismantling the centre console, [McConnell] had to make a few cuts behind the scenes to make room for the wireless charger — as well as cutting down the charger itself. He also took apart the charger and flipped the board and charging coil around inside its case; the reason for this is the closer the coil is to the phone, the better. The charger will already be hidden behind the plastic of the centre console, so it’s no good to be fighting through the extra distance of the charger’s internals. The charger was mounted with double-sided tape, since it’s relatively light and won’t be knocked about.
[McConnell] tapped into the accessory circuit on his truck so it would only be drawing current when the truck is on — nobody likes coming back to a dead battery! Power comes from a cigarette outlet connected to a USB car charger, which then powers the wireless charger — it’s a little hacky, but it works! Once the wireless charger is plugged in and the centre console is reinstalled, [McConnell] was set! Check out the build video after the break.

[Elon Musk] recently staged one of his characteristic high-profile product launches, at which he unveiled a new Tesla electric semi-truck. It was long on promise and short on battery pack weight figures, so of course [Real Engineering] smelled a rat. His video investigating the issue is below the break, but it’s not the link that caught our eye for this article. As part of the investigation he also created an online calculator to estimate the battery size required for a given performance on any electric vehicle.
It’s not perfectly intuitive, for example it uses SI units rather than real-world ones so for comparison with usual automotive figures a little mental conversion is needed from kilometres and hours to metres and seconds if you’re a metric user, and miles if you use Imperial-derived units. But still it’s a fascinating tool to play with if you have an interest in designing electric cars or conversions, as you can tweak the figures for your chosen vehicle indefinitely to find the bad news for your battery pack cost.
It’s very interesting from a technical standpoint to see a credible attempt at an electric truck, and we hope that the existing truck manufacturers will show us more realistic prototypes of their own. But we can’t help thinking that the overall efficiency of electric long-distance trucking could be improved hugely were they to make a truck capable of hauling more than one trailer at once. Any safety issues could be offset by giving these super-trucks their own highways, and with such dedicated infrastructure the power could be supplied from roadside cables rather than heavy batteries. In such circumstances these long trains of electrically hauled containers could be rather successful, perhaps we might call them railroads.

How do you classify something that is gigantic and miniature at the same time? LEGO kit 850, from 1977 when it was known as an Expert Builder set, was 210 modular blocks meant to be transformed into a forklift nearly 140mm tall. [Matt Denton] scaled up the miniature pieces but it still produced a smaller-than-life forklift. This is somewhere in the creamy middle because his eight-year-old nephew can sit on it but most adults would demolish their self-esteem if they attempted the same feat.
[Matt] has been seen before building these modular sets from enlarged LEGO blocks, like his Quintuple-Sized Go-Kart. He seems to have chosen the same scale for the pieces and who wouldn’t? If you’re printing yourself a ton of LEGO blocks, it just makes sense to keep them all compatible. Isn’t combing all your sets into one mishmash the point after all? We’ll see what his nephew/co-host constructs after his uncle [Matt] leaves.
In the time-lapse video after the break, you can see how the kit goes together as easily as you would hope from home-made bricks. With that kind of repeatability and a second successful project, it’s safe to say his technique is solid and this opens the door to over-sized projects to which LEGO hasn’t published instructions.
Hackaday is bursting with LEGO projects, K’Nex projects, and even Erector set projects.

Seeing a half car is always a disconcerting experience. Especially when that half car is about 14 feet up in the air. [PanasonicModelRC6015] — We’ll call him [RC6015] for short — has gone and mounted 1/2 (actually more like 1/4) of a VW Rabbit Caddy pickup MK1 up on his shop wall.
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.

Seems like all the buzz about autonomous vehicles these days centers around self-driving cars. Hands-free transportation certainly has its appeal – being able to whistle up a ride with a smartphone app and converting commute time to Netflix binge time is an alluring idea. But is autonomous personal transportation really the killer app that everyone seems to think it is? Wouldn’t we get more bang for the buck by automating something a little more mundane and a lot more important? What about automating the shipping of freight?
Look around the next time you’re not being driven to work by a robot and you’re sure to notice a heck of a lot of trucks on the road. From small panel trucks making local deliveries to long-haul tractor trailers working cross-country routes, the roads are lousy with trucks. And behind the wheel of each truck is a human driver (or two, in the case of team-driven long-haul rigs). The drivers are the weak point in this system, and the big reason I think self-driving trucks will be commonplace long before we see massive market penetration of self-driving cars.
