"Hi Saad, It flies all right, I think. This was the first flying wing I have ever flown, so I don't really have much to compare it to. I have since bought a HobbyPartz PopWing, and I think my wing actually feels more like it is flying, while the…"

Some Bluetooth and Android sillyness...

Above you can see a screenshot of my latest hack: a remote control app for an Android phone controlling my mini quadcopter via bluetooth. What…

Slightly better mouse sensor position hold video

Posted on October 10, 2010 at 11:08am 10 Comments



After some more PID tuning, here is another video of my quadcopter trying to hold its position via the hacked mouse sensor (plus an ultrasound range finder for altitude control).

This was shot about 2 hours before sunset and the sensor already started having some trouble on my dark and fairly featureless driveway in the shadow - that's why I tried to make it hover over a sandy spot that stuck… Continue

Quad position hold with mouse sensor - some details

Posted on October 4, 2010 at 6:00pm 46 Comments

Hi,
Some people asked for a few more details on the mouse sensor position hold I am experimenting with on my quad (originial post here), so here we go:

As I mentioned in the original post, the sensor is an ADNS 2610 made by Avago. This is a fairly ubiquitous sensors found in many cheap mice - the reason I chose this one is two-fold: there is good documentation available for it (e.g. the…

Quad with optical flow position hold (sort of...)

Hi,

I have been following this site for a while now, I guess it is time to post something myself.

Above is a picture of my latest scratch-built quadcopter running an STM32 ARM processor board with home-brew software. This is my second quad, on the first one (you can sort of see it in my profile picture) I used a home-mode, dual Atmega 328 board.

So far, the quad features the…

Hi marko,

Hope you're doing well.

I remember seeing your fiber-coated (i think) in some post. Can you tell me how much weight the fiber coating adds? What are the practical advantages and disadvantages of the same?

Hope to hear from you soon.

Regards,
Saad

Marko, Thanks for the quick reply. I have built flying wings with the pink foam as well as normal styrofoam, so i can understand when you say the foam requires reinforcement.

150 grams sounds like reasonable weight...may i ask, how well did it fly? :) And, if you had any small crashes/bumps, how much did the fiber protect it?

Thanks for your time

Regards,
Saad

Marko, Thanks for the reply again.
Your wing is flying very nice. I like how it swiftly cuts through the air. I have made a few flying wings (two with help from XFLR5, on ur recommendation on another post a while ago) and it proves useful to design them first. I have been thinking of Fiber-coating, and your video has provided me with the motivation.

I would love to play with your XFLR5 design, so kindly email that to me. Also, if you have a few good resolution pictures of the wing, kindly send me those as well (or send a link if they're online somewhere). That would give me some idea of how to go about the fiber coating. My email is saadtiwana (at) gmail.com

Thanks a lot

Saad
