Gallardo Tutorial All Done

July 1st, 2011

Finally I have found time to finalize the Gallardo after Dan Lavoie’s wonderful tutorial. It is a larger build than the Audi, but also more rewarding. Not without issues, though. I did most of the body part, approximately one third of the whole tutorial, before coming to a dead end where none of the prescribed commands worked. Something was not right in my otherwise beautiful looking part. Eventually I started from scratch again, and this time completed the tutorial without issues. The only thing missing was instructions for modelling the Lamborghini logo on the rear of the car that you see on this SolidSmack page. I must do that on my own, but after having been tutored by Dan it must be a breeze.

The model is also a good test of your PC hardware. At around step 230, with the introduction of meshes, the model started to become seriously demanding to handle for my Q9400@3.2GHz . I first added 2 GB extra RAM (Windows 7, 64 bit), which had absolutely no effect. I then reduced the “Image Quality” sliders found in “Options -> Document Properties” to mid position, and this made the model much more responsive, but it does take no less than two and a half minutes to open from scratch.

HK-450 Alibre and SolidWorks model

November 11th, 2010

I am back with news on my model of the HK-450 helicopter. I originally got stuck because I couldn’t model a proper canopy in Alibre Design, but after having done the great Audi R8 tutorial, I was able to model a decent canopy and assemble the whole shebang in SolidWorks (imported in STEP203 format from Alibre).



Pretty good compared with the real deal….?

Fantastic SolidWorks Tutorial

November 11th, 2010

If you don’t know how to model soft shapes with splines in SolidWorks, I can wholeheartedly recommend a video tutorial by Dan Lavoie where he shows you just how to model an Audi R8 step-by-step. This is pure “learning by doing” and it works very well. I did this model as a novice in SolidWorks (but having 3D experience from Cinema4D and Alibre Express):

Here it is rendered in PhotoWorks:



Look for more info about Dan’s tutorial at www.solidworksaudir8.com.

HK-450 heli on floats

October 13th, 2010


I recently put together a set of floats for a 450-size helicopter. Got a “noodle” from the local pool shop, cut off two pieces, length 32 cm, diameter 7 cm. Sharpened a couple of chopsticks to form a bridge between the pontoons and tied the landing gear onto the noodles with zip-ties. Placed the noodles more or less symmetrically under the main mast to obtain level flotation. Inexpensive, fast, simple and works a treat.

Now all I need to do is learn to avoid capsizing it :-(

Double standards galore

October 13th, 2010

I almost choked on my single malt, when I read our local paper the North Shore Times this morning. First there was this ad from St Ives Baptist Church promoting a sermon and a book on how to escape dangerous Christian cults!

The irony seems to be totally lost on the good folks in said church.

Then a few pages further on the obligatory promotion of soon to be sainted Mary MacKillop, with our allegedly atheist Prime Minister Julia Gillard announcing “measures to protect Mary MacKillop’s name from being commercialised.”

Say what? The whole charade is one big publicity stunt for the Catholic church in the first place, and take a look at the “official” webpage complete with online shop!

It doesn’t get much more commercial than this. How bloody ironic if it wasn’t so sad.

It also seems to be the definition of the game of golf :-(

Great looking New Age nonsense

Baraka – Blu-Ray disc review
Uploaded to Amazon.com 14 September 2010

- Archaic religious practices look great in HD
- Religious buildings, churches and ruins look great in HD
- Meditating monks look great in HD
- Half burnt corpses look great in HD
- Oil well fires look great in HD
- The ravages of war look great in HD
What is the bloody point?

Taken at face value, this random compilation of scenes from all over the world is beautiful, but ultimately a pointless waste of time. The film makers are wasting excellent footage in spreading their childish, simplified message: Modern way of living is bad – ancient beliefs and nonsensical behaviour is good. A most dubious message, especially when delivered by people who utilise all sorts of modern technological gadgets in creating their movie (advanced cameras, computers, scanners, helicopters, jet planes, etc.)

Bending over backwards for (in this case Eastern) religious nonsense is not a helpful act for the future of this planet. It only makes you more ignorant of the problems and their possible solutions.

Why didn’t the team behind this mess try to tell some of the stories that are hidden below the eye candy? There are so many interesting angles, so many conflicting views and interests to illuminate:
- Why were the temples of Cambodia abandoned for hundreds of years?
- Why is the rain forest being felled in South America, and how can this be countered?
- How our early civilisations relied on the timber industry to the extend, that most of the forest in western countries were felled?
- Why some people in India (the untouchables) are forced to live on (and off) the rubbish dumps? (It is not a technological problem but a religious/social problem).
- How religious observance make old ladies rinse their dentures in the very same water that other people wash in, urinate in and discard charred body parts in; and why this is a problem for hygiene.
- What constitutes a humane treatment of animals?
- Etc., etc.

May I recommend, as a substitute, the quite similar but much more persuasive movie “Home” by Yann Arthus-Bertrand. It has a voice-over and presents a very clear message, through pictures and words, that we humans have to change our ways. It is NOT helpful to sit back and await divine intervention while enjoying this eye candy on your HD TV.

Review of E-Flite Blade 400 RTF (ready-to-fly)

September 12th, 2010

The E-Flite Blade 400 RTF is a very nice introduction to the hobby. You get a potent 400/450 size helicopter and a very nice radio system, the Spectrum DX6i with AR6100e receiver and four E-Flite DS75 servos, which are adequate but not exactly outstanding. The only blemish is that the supplied charger for the 3 cell 1800 mAh LiPo only accepts 12V input, so you need a battery or a power supply to get going. Both the heli and the radio comes with pretty good manuals, but they are not integrated, so it is quite a task to locate all the relevant info. The manual has very little info on rebuilding and setting up the helicopter, which is a huge minus, because this info becomes essential sooner or later, so you need to find it on the internet, in magazines or elsewhere.




The Blade 400 is fast, agile and lively, to the extend that it is quite a handful for a novice pilot. It is supposedly ready-to-fly out of the box but, in my case anyway, this claim was a bit of an exaggeration. The problem was, as I discovered through hard study (and a few crashes), that the rotorhead was set up with way too much pitch. With the throttle stick in centre position it would have +5 degrees, and with zero throttle hardly any negative pitch. This means that the heli is very keen to get off the ground, but doesn’t want to come back down, especially when there is a bit of wind. The headspeed is quite low for the same reason, so stability and response is worse than necessary. You simply must adjust the relevant linkages to obtain a better (lower) pitch at centre stick.

The design is very nice and thoughtful – a big improvement (on paper anyway) over older designs such as the Align T-Rex 450XL and clones. Servo placement is fine with aileron and rudder servos placed symmetrical on top of each other with good spacing to the main gear, so there is no chance of binding. The motor is top mounted on a very heavy duty mount and gets maximum cooling air flow. The battery tray is the top part of the frame, so it is very sturdy and the battery straps are fixed and won’t fall off. The frame itself is sturdy moulded plastic and you don’t need to loosen a myriad of screws to replace parts. So, what’s not to like?

Well, I unfortunately suffered some pretty bad tail vibrations (or rather my Blade 400 did), that I simply couldn’t get rid of. I balanced main and tail rotor blades and the complete assembled rotorhead, changed the tail tube (which was bent), changed the main gear, lubricated all and every part including the belt to no avail. The heli would fly ok, but the entire tail was “a blur” due to very rapid vibrations. Eventually I gave up and bought 3 cheap HK-450 kits from HobbyKing and a lot of spare parts including some very nice metal components. I moved most of the components to the HK-450 and it was a blast; easy to set up, very stable and responsive to fly.

As with the mSR, I have some issues with the pricing policy of E-Flite. Its great to be able to buy a helicopter with a very nice transmitter, LiPo, charger, etc.; but why are the spare parts so expensive? I wanted a spare plastic rotor head for the Blade 400, ready to pop-in in case of a crash, to save time and to enjoy putting it together. But building it from spare parts is ridiculously expensive; I stopped counting at $150! And it can’t be bought separately. The same goes for the rest of the components; if you want an extra LiPo to avoid having to wait two hours while charging between flights, it is $100! A similar no-name battery can be bought for $10-20 from HobbyKing and other retailers. And the quality is just as good as the E-Flite stuff, after all, everything comes from China anyway, probably even from the same factories in Shenzhen. The only difference is the branding and the marketing. But I think that it is remarkable, that none of my LHS (local hobby shops) carry spare E-Flite LiPos. That, to me, is a clear indication that the mark up is way off….

So, in conclusion, a good buy, a good way to get into the hobby, but not unproblematic and not really suited for beginners.

PS
I almost forgot the most annoying detail about the Blade 400: The canopy is a very tight fit and to put it on is similar to trying to get toothpaste back into the tube. Really annoying; but the procedure can be made less strenuous by fitting some third party canopy holders.
