Junkyard RC Conversion Looks Like Mad Max Extra

Over the years we’ve noticed that there is a subset of hackers out there who like to turn real life vehicles into remote controlled cars. These vehicles are generally destroyed in short order, either by taking ridiculous jumps, or just smashing them into stuff until there’s nothing left. In truth that’s probably what most of us would do if we had access to a full size RC car, so no complaints there.

As a rule, the donor vehicles for these conversions are usually older and cheap. That only makes sense, why spend a lot of money on a vehicle you intend on destroying? But even still, the RC conversion [William Foster] has recently completed may take the cake. We don’t know how much of the “antiquing” of his donor vehicle was intentionally done, but on the whole, the thing looks like it got dragged from the bottom of a lake somewhere. Presumably, he got a great deal on it.

The video posted to YouTube is primarily about [William] driving his creation around (sometimes from the back seat, no less), but towards the second half of the video there’s a quick rundown on the hardware used to make this pile of rust move.

A standard RC transmitter and receiver combination are used to control a pair of Arduinos mounted in the center console, which are in turn hooked up to external stepper drivers. The wheel is turned via a chain and sprocket arrangement, and the pedals are pushed with homebrew contraptions that look like they are made from lead screws intended for 3D printers.

All in all, it appears [William] has cooked up a fairly responsive control system with commodity hardware you could get on Amazon or eBay. Not sure we’d be backseat driving this thing personally, but to each their own.

We recently covered a Jeep that got a similar remote control upgrade, but these super-sized remote controlled vehicle builds are not just limited to the ground either.

Baby’s First Hands-Free Stroller

So you’ve had your first child. Congratulations; your life will never be the same again. [Dusan] was noticing how the introduction of his children into his life altered it by giving him less time for his hobbies in his home laboratory, and decided to incorporate his children into his hacks. The first one to roll out of his lab is a remote-controlled baby stroller.

After some engineering-style measurements (lots of rounding and estimating), [Dusan] found two motors to drive each of the back wheels on a custom stroller frame. He created a set of wooden gears to transfer power from the specialized motors to the wheels. After some batteries and an Arduino were installed, the stroller was ready to get on the road. At this point, though, [Dusan] had a problem. He had failed to consider the fact that children grow, and the added weight of the child was now too much for his stroller. After some adjustments were made (using a lighter stroller frame), the stroller was eventually able to push his kid around without any problems.

This is an interesting hack that we’re not sure has much utility other than the enjoyment that came from creating it. Although [Dusan]’s kid certainly seems to enjoy cruising around in it within a close distance to its operator. Be sure to check out the video of it in operation below, and don’t forget that babies are a great way to persuade your significant other that you need more tools in your work bench, like a CNC machine for example.

Custom robot transmitter and a few robots (Rpi, nodemcu and arduino)

Hi good people!

I have alot of robotic projects,and now I'm trying to make the one remote to control them all.

I have a lasercut box with a raspberry pi 3 inside, with the original 7 inch touch display, there is also two 3 axis joysticks. The touch display will do everything that I can't do with the joysticks. I currently have a quadroped robot using Phoenix Code controlled with a PS2 joypad. The interfacing on the touch display will be made in Kivy and python.

Man Shoots Lamp

What do you get when you mix together all of the stuff that you can get for cheap over eBay with a bit of creativity and some PVC pipe? [Austiwawa] gets a table lamp, remote-controlled by a toy gun, that turns off and falls over when you shoot it. You’ve got to watch the video below the break.

This isn’t a technical hack. Rather it’s a creative use of a bunch of easily available parts, with a little cutting here and snipping there to make it work. For instance, [Austiwawa] took a remote control sender and receiver pair straight off the rack and soldered some wires to extend the LED and fit it inside the toy gun. A relay module controls the lamp, and plugs straight into the Arduino that’s behind everything. Plug and play.

Which is not to say the lamp lacks finesse. We especially like the screw used as an end-of-travel stop for the servo motor, and the nicely fabricated servo bracket made from two Ls. And you can’t beat the fall-over-dead effect. Or can you? Seriously, though, great project [Austiwawa]!

Making a Vintage Star Wars AT-AT toy walk with an Arduino

Dave Stein is a software engineer during the day and a tinkerer on Arduino projects in his free time after work. He submitted on the blog his first Arduino project with the goal of powering his old AT-AT Walker toy (mid 1980s) with Arduino Uno and make it walk and perform some of the functions we see in the Star Wars movies.

AT-AT (All Terrain Armored Transport) are four-legged combat walkers 22.5mt (73.8ft) tall of the Galactic Empire, one of its most famous military symbols introduced  in “Star Wars V: The Empire strikes back”, and we may see them again in the next weeks on “Star Wars: The Force Awakens” the upcoming episode of the saga opening December 18th.

The AT-AT walker toy updated by Dave is controlled by a wired Xbox 360 controller that interfaces with a computer and transports a signal to the Arduino Uno for walker movement:

The left and right triggers move the walker forward and backward while the right stick moves the head horizontally. If you have ever played with this toy you may remember it was clumsy and difficult to move. In my project I wanted to learn about and conquer the difficulties of quadrupedal movement. The realization process for my project involved a massive amount of trial and error, research, and failures. I have to say that I failed many more times than I succeeded with configuring the servos with the Arduino. I went down many long roads to learn about prototyping with the breadboard, soldering, and redesigns of the final product. The most difficult part of the project aside from adjusting the gait of the walker for balance and movement was providing enough power to the servos without frying the microcontroller or any of the components. I was finally able to overcome these difficulties by implementing the Adafruit servo shield.

Arduino And IR Remote Turn Off Raspberry Pi

With all of the cool features on the Raspberry Pi, it is somewhat notable that it lacks a power button. In a simple setup, the only way to cut power to the tiny computer is to physically remove the power cord. [Dalton63841] found that this was below his wife’s tolerance level for electronics, and built a simple remote control for his Raspberry Pi.

[Dalton63841] started this project by trying to use the UART TX pin, but this turned out to be a dead-end. He decided instead to use an Arduino to monitor the 3.3V power rail on the Pi. When the Pi is shut down in software, the Arduino can sense that the Pi isn’t on any more and disconnect the power. The remote control is used to turn the Pi on. The Arduino reads the IR code from a remote and simply powers up the Pi. This is a very simple and elegant solution that requires absolutely no software to be installed on the Raspberry Pi.

We know that this isn’t the most technically complex project we’ve ever featured, but it is a good beginner project for anyone just getting started with a Pi, Arduino, or using IR. Plus, this could be the perfect thing to pair up with a battery-backup Raspberry Pi shutdown device that allows it to power itself down in a controlled way when a power outage is sensed.
