If you don’t live in a former Eastern Bloc country, odds are that you’ve never seen a Lada driving around your neighborhood. This car is ubiquitous in Russia and its neighboring countries, though, and for good reason: price. Lada gave many people access to affordable transportation who otherwise would have been walking, but this low price means that it’s a great platform for some excellent car hacks as well.
The guys at [Garage 54], an auto shop in Russia, outfitted one of these discount classics with two extra engines. This goes beyond normal bolt-on modifications you typically see to get modest horsepower gains from a daily driver. The crew had to weld a frame extending out of the front of the car to hold all the extra weight, plus fabricate all the parts needed to get the crankshafts on each engine to connect to each other. After that, it was the “simple” job of tuning the engines to all behave with one another.
This video is really worth watching, as the car was also upgraded with a dually setup on the back with studded tires for extra grip on their ice track. Odds are pretty good that this car isn’t street legal so this is likely the only place they’ll be able to drive it. Other things can be built out of Ladas as well, like lawn mowers for example.

The amount of technology in modern cars is truly staggering. Heated seats, keyless entry, and arrays of helpful cameras are all becoming increasingly common in all but the cheapest of models. [mathisox] drives a slightly older Volkswagen van, which has been converted into a camper. Unfortunately, it lacks a proper door ajar display. Nevermind that, though – there’s a charming solution to this problem.
Rather than stick to the automotive standard of boring indicator lights and low-resolution LCD displays, [mathisox] took a more analogous approach. A small model car matching his van was sourced and quickly gutted for the project. It was then fitted with servos to open and close the doors and rear hatch. The servos are controlled by an Arduino Nano, which reads the door switches in the vehicle and actuates the appropriate parts on the model.
With the model car stuck prominently on the dashboard, it serves as a clear visual indicator of the current status of the vehicle’s doors. It’s far less intrusive than those old Chryslers which repeatedly insisted that a door is a jar.

A Jeep is fun offroad, a motorcycle perhaps even more so. Diehard renegades go even further and get about in Unimogs and on snowmobiles. [amazingdiyprojects] might just have topped them all however, with his latest project – the astonishing Inflatable Car.
Despite the name, it’s a vehicle that defies clear definition. Consisting of a lightweight aluminium frame and exposed seat, the construction is almost 100% hacked. PVC fabric is used with advanced adhesive tapes to create inflatable wheels that are 2 meters in diameter. Vacuum cleaners are used to inflate the massive tyres, with custom 3D printed valves to ensure even inflation. Drive is courtesy of four handheld concrete mixers, repurposed for their torquey motors and robust geartrains. Even the user interface is a triumph of found parts – consisting of former cordless drills, used for their PWM hardware and covered in extra switches.
Looking like a moon lander from a strange 1950s version of the future, the machine is impressively nimble for its size. Episode 1 starts with a single wheel hooked up to the inflation gear and a single drive motor. Just a few short months later, episode 7 has the prototype machine crawling out from the confines of the back garden and out into the street. The machine is already impressively fast and capable, and we can’t wait to see what happens next.
It’s a build that is truly impressive in its scale, though we’ve come to expect no less from [amazingdiyprojects]. Video after the break.

These days, the electronics hobbyist is lucky to have access to a wide range of ready-made modules that enable sensors, screens, and microcontrollers to all be linked up with ease. However, this manner of working generally ends up with a project that becomes more of a PCB salad than a finished product. Oftentimes, it’s possible to find something off the shelf that’s close to your requirements, and repurpose it to work. That’s exactly what [Aaron] did.
[Aaron] wanted to install a display in his classic Jeep to display the time and some basic parameters. A screen and a microcontroller were called for, and a cheap open-source transistor tester had exactly that already. Consisting of an ATmega-328P linked up to an 128 x 64 graphic LCD module, it had most of what [Aaron] needed from the get go.
To repurpose the device, [Aaron] started by swapping the 8 MHz crystal for a 16 MHz one to make it more easily programmable through the Arduino IDE. Then, a custom firmware was written, which communicates with a DS3232 real time clock, temperature and pressure sensors, and also monitors battery voltage. It’s all neatly installed in the vehicle behind a 3D printed faceplate, and the graphic LCD is clear and easy to read – if you speak German.
[Aaron] has helpfully outlined the various online resources that helped with the hack, including the transistor tester schematic. Our very own [Adam Fabio] reviewed these units in 2015.
If you’ve cleverly reused some existing hardware yourself, be sure to let us know on the tip line. Video after the break.

In the world of Internet of Things, it’s easy enough to get something connected to the Internet. But what should you use to communicate with and control it? There are many standards and tools available, but the best choice is always to use the tools you have on hand. [Victor] found himself in this situation, and found that the best way to control an Internet-connected car was to use the Flask server he already had.
The remote controlled car was originally supposed to come with an Arduino, but the microcontroller was missing upon arrival. He had a Raspberry Pi around, and was able to set that up to replace the Arduino. He also took the opportunity to use the expanded functionality of the Pi compared to the Arduino and wrote a Flask server to control it, which is accessed as if you are communicating with a chat bot. Sending the words “go left/forward” to the Flask server will control the car accordingly, for example.
The chat bot itself contains some gems as well, and would be useful for any project that makes use of regular expressions. It also seems to be easily expandable. The project also uses voice commands, and does so by making extensive use of Mozilla’s voice recognition suite. If you want to get deep in the weeds of voice recognition on your own though, you can also explore TensorFlow at your leisure.
Part of the fun of watching action movies is imagining yourself as the main character, always going on exciting adventures and, of course, being accompanied by the perfect soundtrack to score the excitement and drama of your life. While having an orchestra follow you around might not always be practical, [P1kachu] at least figured out how to get some musical orchestration to sync up with how he drives his car, Fast-and-Furious style.
The idea is pretty straightforward: when [P1kachu] drives his car calmly and slowly, the music that the infotainment system plays is cool and reserved. But when he drops the hammer, the music changes to something more aggressive and in line with the new driving style. While first iterations of his project used the CAN bus, he moved to Japan and bought an old Subaru that doesn’t have CAN. The new project works on something similar called Subaru Select Monitor v1 (SSM1), but still gets the job done pretty well.
The hardware uses an Asus Tinkerboard and a Raspberry Pi with the 7″ screen, and a shield that can interface with CAN (and later with SSM1). The new music is selected by sensing pedal position, allowing him to more easily trigger the aggressive mode that his previous iterations did. Those were done using vehicle speed as a trigger, which proved to be ineffective at producing the desired results. Of course, there are many other things that you can do with CAN bus besides switching up the music in your car.

When referring to classic cars, there’s a good reason that “they don’t make ’em like that anymore.” Old cars represented the limits of what could be done in terms of materials and manufacturing methods coupled with the styles of the time and cheap fuel. The result was big, heavy cars that would cost a fortune in gas to keep on the road today.
Some people just don’t want to let those styles go, however, and send their beast off for some special modifications. This 1949 Mercury coupe with an electric drivetrain conversion is one way of keeping that retro look alive. Granted, the body of the car is not exactly showroom quality anymore, from the light patina of rust on its heavy steel body panels to the pimples cropping up under its abundant chrome. But that’s all part of the charm; this comes from conversion company Icon’s “Derelict” line, which takes old vehicles and guts them while leaving the outside largely untouched. This Mercury was given a fully electric, 298 kW drivetrain. The engine bay and trunk, together roomier than some Silicon Valley studio apartments, provided ample room for the 85 kWh Tesla battery pack and the dual electric motors, with room left over to craft enclosures for the battery controllers that look like a V8 engine. Custom electronic gauges and controls that look like originals adorn the chrome-bedazzled dash. The beast tops out at 120 mph (193 km/h) and has a 200 mile (322 km) range before it has to find a Tesla supercharger. Or a lemonade stand.
Say what you want about the old cars, but they had plenty of style. We appreciate the work that went into this conversion, which no doubt cost more than all the gas this thing has ever guzzled.
