How To Get Into Cars: Drifting Mods

January 4, 2021 by Lewin Day 31 Comments

Drifting is a hugely popular motorsport unlike any other, focusing on style and getting sideways rather than the pursuit of the fastest time between two points. It’s a challenge that places great demands on car and driver, and proper attention to setup to truly succeed. Here’s a guide to get your first drift build coming together.

Getting Sideways (And Back Again)

Drift cars are specialised beasts, and like any motorsport discipline, the demands of the sport shape the vehicle to suit. If you’re looking to drift, you’ll want to choose a project car with a front-engined, rear-wheel drive layout. While it’s somewhat possible to drift with other layouts, the act of kicking out the tail and holding a slide at speed is best achieved with the handling characteristics of such a vehicle. It all comes down to weight transfer and breaking traction at will. Of course, over the years, certain cars have become expensive on the second-hand market due to their drift prowess, so you may have to get creative if your first choice isn’t available at your budget. It pays to talk to the drifters down at your local track to get an idea of which cars in your area are the best bet for a drift build. Once you’ve got yourself a car, you can get down to installing mods!

Active Suspension R/C Car Really Rocks

January 13, 2020 by Kristina Panos 27 Comments

When you’re a kid, remote control cars are totally awesome. Even if you can’t go anywhere by yourself, it’s much easier to imagine a nice getaway from the daily grind of elementary school if you have some wheels. And yeah, R/C cars are still awesome once you’re an adult, but actual car-driving experience will probably make you yearn for more realism.

What could be more realistic and fun than an active suspension? Plenty of adults will never get the chance to hit the switches in real car, but after a year of hard work, [snoopybg] is ready to go front and back, side to side, and even drift in this super scale ’63 Oldsmobile Dynamic 88 wagon. We think you’ll agree that [snoopybg] didn’t miss a detail — this thing makes engine noises, and there are LEDs in the dual exhaust pipes to simulate flames.

An Arduino reads data from a triple-axis accelerometer in real time, and adjusts a servo on each wheel accordingly, also in real time, to mimic a real car throwing its weight around on a real suspension system. If that weren’t cool enough, most of the car is printed, including the tires. [snoopybg] started with a drift car chassis, but even that has been hacked and drilled out as needed.

There are a ton of nice pictures on [snoopybg]’s site if you want to see what’s under the hood. We don’t see the code anywhere, but [snoopybg] seems quite open to publishing more details if there is interest out there. Strap yourself in and hold on tight, because we’re gonna take this baby for a spin after the break.

If this is all seems a bit much for you, but you’ve got that R/C itch again, there’s a lot to be said for upgrading the electronics in a stock R/C car.

Electric Drift Trike Needs Water Cooling

December 12, 2018 by Bryan Cockfield 10 Comments

Electric vehicles of all types are quickly hitting the market as people realize how inexpensive they can be to operate compared to traditional modes of transportation. From cars and trucks, to smaller vehicles such as bicycles and even electric boats, there’s a lot to be said for simplicity, ease of use, and efficiency. But sometimes we need a little bit more out of our electric vehicles than the obvious benefits they come with. Enter the electric drift trike, an electric vehicle built solely for the enjoyment of high torque electric motors.

This tricycle is built with some serious power behind it. [austiwawa] constructed his own 48V 18Ah battery with lithium ion cells and initially put a hub motor on the front wheel of the trike. When commenters complained that he could do better, he scrapped the front hub motor for a 1500W brushless water-cooled DC motor driving the rear wheels. To put that in perspective, electric bikes in Europe are typically capped at 250W and in the US at 750W. With that much power available, this trike can do some serious drifting, and has a top speed of nearly 50 kph. [austiwawa] did blow out a large number of motor controllers, but was finally able to obtain a beefier one which could handle the intense power requirements of this tricycle.

Be sure to check out the video below to see the trike being test driven. The build video is also worth a view for the attention to detail and high quality of this build. If you want to build your own but don’t want to build something this menacing, we have also seen electric bikes that are small enough to ride down hallways in various buildings, but still fast enough to retain an appropriate level of danger.

Low-cost Drift Buoy Plies The Atlantic For Nearly A Year

April 28, 2017 by Dan Maloney 34 Comments

Put a message in a bottle and toss it in the ocean, and if you’re very lucky, years later you might get a response. Drop a floating Arduino-fied buoy into the ocean and if you’ve engineered it well, it may send data back to you for even longer.

At least that’s what [Wayne] has learned since his MDBuoyProject went live with the launching of a DIY drift buoy last year. The BOM for the buoy reads like a page from the Adafruit website: Arduino Trinket, an RTC, GPS module, Iridium satellite modem, sensors, and a solar panel. Everything lives in a clear plastic dry box along with a can of desiccant and a LiPo battery.

The solar panel has a view through the case lid, and the buoy is kept upright by a long PVC boom on the bottom of the case. Two versions have been built and launched so far; alas, the Pacific buoy was lost shortly after it was launched. But the Atlantic buoy picked up the Gulf Stream and has been drifting slowly toward Europe since last summer, sending back telemetry. A future version aims to incorporate an Automatic Identification System (AIS) receiver, presumably to report the signals of AIS transponders on nearby ships as they pass.

We like the attention to detail as well as the low cost of this build. It’s a project that’s well within reach of a STEM program, akin to the many high-altitude DIY balloon projects we’ve featured before.
