Mareeba Tropical Savanna and Wetland Reserve

The Mareeba Tropical Savanna and Wetland Reserve is located only an hour’s drive from Cairns or Port Douglas, yet offers the visitor tours and activities that are an authentic Australian experience in the heart of the outback.

Set within the savannas of North Queensland, it is a gateway to Cape York Peninsula and the Gulf Savannah, and provides an excellent base from which to visit the World Heritage listed Wet Tropics Rainforests and Great Barrier Reef, as well as the Cairns Highlands and Atherton Tablelands.

The Reserve, known locally as the Mareeba Wetlands, protects over 5000 acres of savannas and wetlands, providing a sanctuary for much of tropical Australia’s savanna and wetland flora and fauna, and cultural heritage.

Computer Upgrade….

after many failing bits, dodgy RAM, corrupt data and general lack of anything decent in terms of FPS during so of the even least intensive games it was decided that it had to go…well not quite it will get farmed downstream for something else, but definietly without the dodge bits…

so let me start from the beginning..or close there of…

got donated a Abit NF7-S from a mate, hence decided need a new case and obviuosly at that point matching processor and RAM, if I remember correctly it was a AMD athlon 3000XP or thereabouts…

Nice setup in the case, multiple HDD’s buy cooling was a bitch and the northbridge fan screamed fromtime to time…something after this minor upgrade was the additon of a decent (at that time anyways..) videocard. NVIDIA 5700 ultra – was never particularly impressed by it, ran loud and heated up my case!

Next came the cooling upgrade, quite a whule after the video card came out, so a tracked down a dirt cheap cooler for the vid card from www.pccasegear.com.au, on special for $9 or something silly. Also picked up a stack of nice quiet nexus 80mm fans…..so what about that northbridge..yep fixed that screamer with a passive cooler..looks funky too.

so this setup ran nice and quiet and had reasonble performance….could run CSS on its defaulted selected values (no HDR etc) and get about 35fps in the benchmark…nothing to write home about…but hey its worked!

decent cooling and a fairly stable system resulted in some overclocking, mainly on the video card…

using rivatuner (excellent program by the way) I bumped the 5700 ultra up to a core speed of 580 and memclock speed of 1100. With these setting I was getting a nice 48-50fps in the CSS bench, cooling was no issue barely even noticed it.

typically 23-25 degrees during idle and up to 50 degrees during stress.

So finally the 2008 upgrade, here are the specs. Note made the switch from AMD to Intel for the Proc on this occasion.

Proc: Intel E8500 (runs dual 3.16Ghz)

RAM 4gb Geil (nothing really special just 5 stuff)

Mobo: MSI P45-NEO2

Video Card: Gigabyte ATI/AMD HD4850

Power Supply: Corsair HX620

Strangler Figs

The Strangler Fig is a tall canopy, widely buttressed tree which grows to 45m in height. The top of this tree spreads like an umbrella. It features light coloured bark. In the rainforest the strangler fig germinates only in the branches of a host tree from the seed deposited by birds. Many roots are sent down and they gradually envelope and strangle the host tree leaving the fig in its place. There are five species of strangler fig represented in the Park.
Leaves:Leaves are simple, large, glossy green above and paler below. Commonly betwwen 4 and 7cm in length.
Flowers: The flowers are on the inside of the fruit and are pollinated by a wasp which enters the fruit through a small hole before the fleshy part of the fruit develops.
Fruit: Fruit is large (about 3cm with a nipple on the end) decorative and tasty which means that it is relished by birds. The fig is dark purple when ripe with yellowish dots, fleshy and ovular. They are a most important food tree for birds

Constant Speed Prop

DSC_5854.jpgInteresting units these… all the more so when ya get to pull them apart, and yes the grease was handy :) This one is a recent MLG failure victim (Chieftian if I remember correctly), quite a nice Hartzell in its working days…dsc_5856.jpg

Propeller construction may consist of an aluminum “clam-shell” hub where the hub captures the blades, or a steel hub “spider” design where the blades are clamped to a hub . The blades may be made from an aluminum forging or from either Kevlar 49® or Carbon based fabrics or unidirectional tapes. The composite blades would additionally incorporate a leading edge erosion sheath to protect the blade from both abrasion (sand) and erosion (water) as well as offer an external conductive for a lightning strike.

The pitch control typically comes from a hydraulic fly-ball governor mounted on the engine. The governor senses whether the engine/propeller is running at the correct RPM and either supplies or maintains oil flow to the propeller, or drains oil to the engine sump. Of course, it is very important that the engine-mounted governor be properly matched to the propeller for proper pitch change command and response. The governor may or may not be supplied by the propeller manufacturer; however, it is necessary to ensure the propeller manufacturer has approved the governor for use with its propeller. In addition to controlling the propeller, this governor typically contains a pump that increases the oil pressure to a higher level than that which the engine supplies to a value sufficient to control the propeller.
