My new car(s)

I got this car, a Losi 1/24 Short Course Truck (SCT) a week after I bought the ECX Smash. And since then I’ve bought a lot of extra stuff for it. Originally it was defect with a brushed engine. It nearly worked, but I quickly ordered a a new brushless engine on Ebay. I also went to the local RC store and bought a set with pinions gear. found out later that I already had a pair laying around, plus there where some that was in the package the car come in. So now I have a lot of them. What you see underneath is not the SCT edition, but the Truggy. It got bigger wheels, a cool spoiler, and a lot smaller space under the “hood”. The bigger wheel made the Losi run a lot better outside, but the hood was a bit cramped to keep all the electronics inside it. So now I’m back to the SCT body, but I modified it to use the same big wheels!losiTruggy

So on to my next car. You may remember my Nitro to Electric conversion of the old Tamiya TGX MK.1? I finally bought a proper engine too it, the Mamba Monster v.1 which I found on Finn.no for a fair price. A week later this package arrived at my local mail store.

mamba-0It was pretty heavy, and it was several reasons for that. Mostly because the guy that sold the engine wanted to get rid of his two cars too. So I got them too. Plus some other stuff.

mamba-1 mamba-2As you can see it was fairly well package. With a lot of paper. He even sent me his old tool-kit which has been wonderful! And I use it every time I work on my cars. Plus some spare parts. There was even a light controller (I think it that).

mamba-3Here are some more images of the car. The body is a bit to big, and after some Googling I found out that it is supposed to look like this (it’s a fuel car, what a coincident).

mamba-5Too much air around those wheels for my taste.

The other car he had sent was a Sakura Zero by 3Racing used for drifting. Sadly it is missing way to many parts. So I’m just going to scrap it. Probably saving every part in a bag.

Enjoy some “inside” photos.

Nte: G-force from driving

Screenshot - 03022013 - 04:45:32 PM

Some weekends ago I was working on my old Nitro car. The one I’ve switched the engine on. In image two from that post you can see some circuits boards. What you see is an Arduino, Xbee, and a three dimensional accelerometer. The Arduino do all the processing of data, and sends it via Xbee to my computer. Using the data gathered with the three dimensional accelerometer it was possible to map out the g-force that the car generate.

So what you can see in the image is the g-force generated by my car. Next step is to make a more readable display.

Update: Waterproofed RC car

So, yeah…a couple a days ago I thought I had managed to waterproof my RC car. Turns out I was wrong. Today when I tried to start the car, nothing happened. So I took it up to my apartment and opened up the ESC. Guess what I found inside, water. Now I’m waiting till it will dry and hoping that it will get better. Or else I have to buy a new one. Guess I’m going for something waterproof then. :\

RC & AI

Not much time to blog personally lately, mostly because I’m a bit lazy. Plus I’m writing on my master thesis, so I feel that I write enough.

“Anywho”, I have an RC car I want to modify in some way. I have changed it gasoline engine to be electric (not that hard, just change the two engines and get the right gear(s)), but what more can I do? I’ve been thinking about making it drive by it self (hence the Artificial Intelligence in the title), but is that any fun? Of course it would be a challenging and interesting coding job, but fun with RC cars is to drive them your self. So what can I do? I googled it a bit, and found these cool project.

HackedGadgets: Use the motor from a drill instead of a “proper” RC car engine. I’m going to try this this weekend. Since I have a spare drill laying around, and a spare RC car (had to get the electric engine from somewhere). Just need another set of batteries, but they aren’t that expensive.

JBProjects: Make a programmable RC car. This is similar to how you program a Lego MindStorm robot. Probably not going to do this on my big RC car, but I have a small one which is kinda broken with no projects going on. So with a h-bridge and an Xbee or something similar, this should be easy to get up and going. Guess the main challenge is to understand how fast it can go, and get it to turn properly :\ We’ll see later when I get time to build this. Plus I need to buy some wireless communication parts.

RCArduino: What about adding traction control or speedometer to the RC car? Both of these could be really fun to try out.

One project I have thought up my self it to make more crash proof. I’m not that a great driver of RC cars so sometimes I crash, but what if I could make the car handle better, or at least withstand the crashes? Some sort of rollcage. With some solenoid I could make it fill over like in the movies. That would be pretty cool.

Or another project would be just to add some cool lights underneath it, and maybe add movable shocks.

Any other ideas?

Germany!

Waiting for pizza atm and preparing a blog post. Not that much free wifi. So, Im now right next to The Nurburgring. Going to try it out tomorrow. Exciting! Ive also posted some pictures. First is a cool licenplate, then my new sneakers. I ordered something I thought was cheese, but no. At last we have an awesome logo, which I spotted on a Chinese dentis car. We where at the Mercedes Benz museum. Ill post more picture when I get home.
