This is the first in our series of videos meant to spread the hacking goodness far and wide on the net. As you can see, it is a pretty silly video, hopefully you enjoyed the humor. This wouldn’t be hackaday without an appropriate writeup though!
Initially the idea was to make this as a device that my boss could deploy from his Tesla Model S. Ultimately, we missed the release of SkyFall, so the whole 007 theme seemed a little flat. However, we did just happen to have a wonderful woman in the office that agreed to be an “overly attached girlfriend”. Here’s a link to the meme for those who are unfamiliar. Even though we made her look like a crazy person, she was a great sport about it (Thanks [Stephanie]!).
The Goal was to have a radio controlled device that would send live video and audio to someone and had the ability to plant a small GPS tracker on the undercarriage of a car.

Okay, the kid does have a face, but it looks like Dad blurred it for his protection. The real story here is the killer ride built by his engineer father. It’s far nicer than the cars driven by the Hackaday team, but then again, since it cost more than a BMW 3 series that’s no surprise.
[Lingzi] lives in China and does custom car work for a living. So to take on this project for his son was more of a stretch of the pocketbook than of his skill set. The car features a custom frame with rack and pinion steering, disc brakes, a rear differential, and a reputable suspension system. The body of the vehicle is crafted from carbon fiber. The lights all work and there’s an electric motor and transmission mounted just behind the driver’s seat. Unfortunately there’s no video of this in action (China blocks YouTube). But do take a look at the album above for pictures of the final paint job. There is also a little bit more information to be found in [Lingzi’s] Reddit discussion.
We hope [Kabir’s] driving skills are top-notch because the camera stuck to the front of this toy is a high-ticket item. It’s ironic, since the donor toy for this hacked RC car only cost about five bucks. It had been gathering dust in the dark reaches of his bedroom until he sat down and gave it a proper upgrade.
He started the project by getting rid of the stock battery and moving to a pair of Lithium Polymer cells. They give the vehicle more power and more than twice the running time between charges. A couple of springs were added to the suspension system for a smoother ride. Turning had been a problem since the original design offered no control over how far the wheels turn. You can just make out the body of the servo motor he rolled into the system to allow for more precise turning.
The most recent addition is the HackHD camera on the front of the vehicle. It records to an SD card rather than streaming the video in real-time. Check out the clip after the break to see the interesting perspective achieved by filming so low to the ground. The one thing we would add is a cage around that board which retails at around $165.

This juicy hunk of printed circuits is an open source controller for the peripherals of an electric car. It’s the product of a capstone project working on a vehicle aimed at urban commuting. There wasn’t a suitable non-proprietary module for controlling a car’s peripherals so the team built their own.
As far as we can tell this is not responsible for driving the vehicle itself. We assume there’s another piece of hardware which reads from the accelerator pedal, drives the motors accordingly, and handles things like regenerative braking. But there’s a lot of other things in a modern vehicle that need to be taken care of as well. Head, tail, and turn indicator lights must be switched. All of the dashboard controls (like the turn signal lever and the wiper blade speed settings) need to be monitored. Something needs to drive the door locks, and a system that reads the door ajar sensors and switches the dome light on and off must be handled. This is where the controller pictured above really shines.
The team has released all of the hardware information. The code is not yet available, but will be as soon as they’ve cleaned it up enough to package the first release candidate.
From this view we would think the handmade wooden roadster (translated) was street legal. But it’s missing a few items that are required to take it out on the highway. The teenagers that built it were pulled over the other night (translated) and cited for driving without a speedometer or side indicator lights.
The image above shows the mark II of their design. Sadly they crashed the first version, which gave them a chance to overhaul the entire design. Now they have a proper frame which was welded from steel square tube. It’s got an impressive rack and pinion steering system and shock absorbing suspension in the front and rear. A dirt bike engine mounted behind the seats drives the rear wheels via a chain. They’ve used an Arduino to add turn signals, and have headlights for night driving.
[Gerrit] sent in the tip on this one and he figures that with an Arduino already being used in the vehicle it should be a quick fix to add a speedometer and get back on the road.
[Tim] drives a 1995 Mitsubishi TS Magna, which is equipped with a less than stellar accessory package he lovingly calls a “poverty pack”. He outfitted his ride with an aftermarket head unit that can support the Bluetooth A2DP profile, provided he buys the ridiculously overpriced kit sold by Pioneer. Reluctant to shell out more money on an audio kit than his car is worth, he whipped up his own Bluetooth kit for far less than Pioneer’s asking price.
He had a set of Nokia Bluetooth headphones that he was willing to part with, so he disassembled them to see how he might interface with his car stereo. Connecting the headset to his head unit was a relatively easy task, but he had to work a bit harder to get his Bluetooth receiver powered properly.
After both undervolting and then nearly cooking his wireless audio rig, [Tim] managed to get things operating to his liking. He says that the audio is a touch quieter than he would like at the moment, so he will likely be revising his design in the near future. For now however, he can stream tunes from his phone while he cruises around town.
So yeah, this thing exists. Well, at least some pretty interesting looking prototypes of it do. It’s the C-1 from Lit Motors (anyone else think that’s a reference which belongs in /r/trees?). The idea here is that the small form-factor of a motorcycle is very efficient and easily maneuverable. But the cage protecting the passenger from harm, and the canopy keeping the elements out give it some of the desirable traits of a car.
Design aside, check out the video after the break. The prototype uses two horizontally positioned gyroscopes placed beneath the passenger seat, just in front of the rear wheel. The builders take it out on a hockey rink and give it a few kicks and slide a few tires into it. Sure, it reacts to the impact but it doesn’t fall over.
Want to see some fast-motion welding of the C-1? Right now there’s a one-minute clip up on the company’s main page.
