I'm back to developing stuff.. And I can already show you something cool.. here is the very first FreeIMU v0.4.1 prototype, featuring MPU6050, HMC5883L, MS5611. Testing it next days.

Laser cutter on plexiglas

Submitted by fabio on Sat, 2011-10-29 18:57.

Today, I've been once again at the Fablab Italia to assist a conference about digital fabrication in Italy.

While I was there I had the opportunity to finally see their professional laser cutter in action. The guys where cutting a 1 cm thick (I think) plexiglas panel.. The precision of the process is incredible and very cool to see live. Here you have a short video on that:

Where are you Fabio?

Submitted by fabio on Thu, 2011-10-06 16:07.

If anyone out there is wondering about my recent quietness here and on the online communities I'm used to frequent, it's because I'm studying hard!!!

I'll be having the Ph.D admissions exam on the 27th and 28th October. The exam shouldn't be extremely difficult but I have to study and a lot!

So, that's it.. I hope to be able to get back with good news from this.
Looking forward working again on my projects and blogging about them soon.

All you guys take care!

A flying monster for aerial video shooting

Today, I've been at the 4th Multirotors and FPV Day in Bologna. I really had a good time.. I had a chance to meet many of the Italian 4copters friends and make new ones.

Of course, I've seen some really awesome developments (some of them based on my FreeIMU ;-)).. but the copter in the following video was absolutely incredible. Awesome!

MPU6050: finally?

Submitted by fabio on Fri, 2011-09-16 12:01.

You know the MPU6050, right? The 3-axis accelerometer and 3-axis gyroscope capable of 9 DOM on chip orientation sensing with a 3rd party magnetometer, right? If not, here is all the info you need.

Well, Invensense guys (the company who produces them) have been doing marketing for more than a year now but its availability has been delayed for many times.. Personally, I think this was just a marketing move, they actually never had the sensors they were just saying they would have had soon, so that they would create hype and interest around their product.

However, sooner or later they needed to deliver something as I'm sure that with this strange marketing approach there are many projects out there which are waiting for that sensor to be available.. not good.

Well, it finally seems they'll start to deliver the sensors. They just press released news of commencement of high volume shipments of the MPU-6050.

So, it looks like we'll finally see this "good on paper" sensor finally implemented in some projects.

Personally, I've been able to get 15 MPU-6050 through some very helpful friends (who got them from cdiweb) so experimentation on this sensor will start soon. FreeIMU v0.4 PCB are already here and ready to be soldered.

It will take some time though...

My first quadcopter flights!

Submitted by fabio on Sun, 2011-08-28 12:04.

As you probably know, I've spent some of my few free time to build a quadcopter.. I bought some components, I had a frame as gift from a friend, mounted everything and finally I went to fly it.

This video documents my very fist flights with it.. this is really nothing easy! And I'm still learning so don't laugh at me! But, as you can see from the last part of the video, my thumbs are getting more and more experienced ;-)

Thank you! Unbelievable success of FreeIMU v0.3.5_MS sale!

Submitted by fabio on Sun, 2011-08-28 09:32.

Guys, you really blown my mind! We sold 60 FreeIMU v0.3.5_MS in just one afternoon! That's incredible!

I really wanna to thank you all of you who supported the project and bought one (or more) units! It's really incredible to see such huge amount of love for my project! I hope all of you will be satisfied by FreeIMU, if you need any kind of help using your FreeIMU just leave a question on FreeIMU answers page or on Jussi's thread.

Of course, I really wanna thanks Jussi Hermansen for taking the risk of financing this batch and for sourcing the various components and sensors. This wouldn't have been possible without his help and guidance! Thanks Jussi!

I also wanna thank all the various supporters of the projects who bought some of the early FreeIMU v0.1, v0.2, v0.3.* prototypes. The success of FreeIMU v0.3.5_MS wouldn't have been possible without your constructive comments and testing.

For those of you who weren't able to get one of the FreeIMUs, you have two possibilities:

  • wait some days, I plan to finish the remaining 35 v0.3.5_MS and 50 v0.3.5_BMP for the 5-11 September week
  • build your own using the open hardware designs available here (let me know if I can help you in the building process)

Thanks!

My Quadcopter, almost ready

Submitted by fabio on Tue, 2011-08-23 17:25.

So here it is. After I bought all the components and after the first assembling, here is a picture of the current state of my quadcopter.

I do now have all the components connected, the propellers mounted and everything is almost ready to fly. Right now I'm facing some ESC programming headaches: never did this before and all this beeping is getting me crazy!
