Toys Exceed Pitts S2A third flight (wind and broken rudder)

Posted by Akom • Tuesday, September 9. 2008 • Category: Toys
I finally have a fully charged battery so I'm off to have a nice long flight. Or so I thought.

So there was some wind this morning - not too much, I figured - I can handle this, I've flown with wind in the simulator. Went out to a different field today - more open, less wind cover. Took off from a sandy path, plane rolled easily and I pointed it into the wind for takeoff. It took off before I even asked it to, and the fun began

Code and Hacks Syncing, Google Calendar, Google Contacts, Blackberry, Outlook, etc

Posted by Akom • Monday, September 8. 2008 • Category: Code and Hacks
As the CTO of Namaste Holistics and Nutrition 4 Entrepreneurs (see links in nav above), I was dealing with a progressively more dissatisfied CEO, and with good reason.

She is dealing with an overcomplicated email/calendaring/contacts setup that's somewhat... imperfect.

The following is the setup and what was done to improve it.

Toys Exceed Pitts S2A second flight

Posted by Akom • Sunday, September 7. 2008 • Category: Toys
The broken wing was dry this morning (see previous post) and the wind was almost nonexistent, despite the hurricane that went through overnight.

I'm off to fly! This time around I moved the servo pulls to the second hole, making the controls slightly more sensitive (I have been getting better with the simulator, and the last flight it felt a little unresponsive). I also set the elevator to fully horizontal position - I had it pointed down slightly last time, also out of caution, but this morning it didn't even want to take off this way.

It flies!

Toys Exceed Pitts S2A first flight (and crash)

Posted by Akom • Saturday, September 6. 2008 • Category: Toys
First flight! Yay! I guess I consider myself good enough after playing with the simulator for a while.

After a little trimming (adjusting the servo pulls with the tiny allen wrench they supply) I got on my runway (a paved road on a park slope) and (with some trepidation) pushed the throttle forward. It took off, with some effort, and flew!

I think it flew with what others have described as a tail-heavy tendency - it seemed like I was always pulling too hard on the elevator - or maybe I was, in the turns, I'm not sure. In any case, all I had to do was push the nose down every so often and it would avoid stalls... which it survived just fine anyway, just taking a small dive and recovering. I circled the area for about 2 minutes, and then just as the plane was getting away from me to the point of "a bit too far", it suddenly disobeyed...

Reviews My Review of the Innovatek 362 DTM Head unit with DVD,TV,MP3,Rear View Camera

I got this thing for our Conversion-Conversion Van. I wanted it to do everything for me. (Also take a look at our Wanna-B-RV(ers) blog entry on this)
The innovatek box
Overall I can't say that I'd recommend this unit, but for some specific applications (such as ours) it seemed to work out.

The breakdown:

Toys Assembling the Sapac Exceed Pitts S2A 4ch R/C plane (and some improvements)

Posted by Akom • Friday, September 5. 2008 • Category: Toys
I have to admit, I've never owned a real R/C plane before, so the following may be painfully obvious to someone who has. When I say real I mean hobby grade. OK I admit it, I had a Hirobo Shuttle nitro heli for a while, but I crashed that so many times that I'd rather not go there. What I learned in the process though is - simulator software is not optional. So this time around I borrowed a friends' copy of Realflight G4 with the controller. I am steadily getting better.

Anyway, so I bought the RTF version, which, I have to keep reminding myself, stands for Ready-To-Fly. Raidentech.com is one of the few places that sold it at the time and I found a free shipping code (CJFREESHIPPING) on somone else's blog. It eventually arrived, in a very large box (OK so I should have expected that, the plane has a 3 foot wingspan). On to assembly...

Java Convincing JAX-WS on Axis2 1.4 to handle overloaded web service methods

Posted by Akom • Saturday, August 16. 2008 • Category: Java
This week I found myself in one of those situations...

I had initially implemented corporate web services in Axis2 1.2, using ADB data binding, starting with a WSDL. Only problem is - the WSDL I had to reimplement came from .NET, sometime around 2001... when overloading must have seemed like a good idea. Since then it's been abolished by just about everyone, including of course the current WSDL specifications. Moreover, the WSDL was most likely auto-generated by .NET with no regard for how manageable it would be. Yes, this is an experience infused with "ArrayOfAnyType", <anytype xsd:type="string">, and other such pearls.

I can't say that ADB handled overloaded methods
