Scrubs up pretty good eh.
Marcus took "Michelle" to the Brigidine Semi Formal on Saturday night. Gina Horky made a corsage that Marcus presented to the girl. I believe the affair went off well and was held at the Indooroopilly golf club.

A stroll in the green forest
Megan and her cohort of Ofambulators & Serial Hillers did a training walk.

WA should ditch helmet laws, say cycling guru
http://au.news.yahoo.com/thewest/a/-/news/13614581/wa-should-ditch-helmet-laws-say-cycling-guru/
And I thought the first thing Campbell Newman would do was scrap the helmet laws so people would ride his bikes.
WA's bike helmet laws should be scrapped to encourage more people to cycle, according to one of the world's most respected pro-cycling lobbyists.
Manfred Neun, president of the European Cyclists Federation, believes the number of cyclists in WA would treble if helmets were not compulsory.
"Helmets are a disincentive to riding, there is no doubt about that," Mr Neun said at the International Transport Forum in Leipzig, Germany, yesterday.
"And if people aren't riding, they aren't enjoying the many health benefits associated with this pastime."
Mr Neun, known as a cycling guru for his worldwide campaigning for improved cycling conditions over 30 years, said politicians and health organisations supported helmet laws because they thought they improved safety for cyclists.
But he said the truth was far more complex.
"Wearing a helmet creates the image of cycling being an abnormally dangerous physical activity," he said.
"While this may be the case for cycling as sports, it is not necessarily so for cycling as a daily means of transportation.
"Statistics show that the more cyclists are on the road, the safer it is actually to cycle. Car drivers are more used to the presence of cyclists.
"There is no doubt that the main effect of bike helmet laws has not been to improve cycling safety but to discourage cycling, undermining its health and other benefits."
Mr Neun said dedicated bike lanes and reducing car speeds in urban areas would do more to protect cyclists than helmets.
Cycling was proving the answer to many problems facing fast-growing cities all over the world, including traffic congestion, energy use and pollution.
Governments were beginning to understand cycling was a relatively "cheap" investment that could create dynamic, livable communities.
"Bike infrastructure is cheaper than new roads, cheaper than new buses and trains," Mr Neun said. "It makes good economic sense and can go a long way to improving a community's health and lifestyle."

BGS Music Showcase
All day today (starting at 6:30am) Marcus attended rehersals for the BGS music showcase. His rehersals were at that fine GPS school known as Terrace. Students from all 9 GPS schools get together and practice for tonights performance. The performance consisted of three acts. A choir to start with followed by a band of some sort followed by the concert band that Marcus was in.
Marcus is front middle of the photo with a Basson. Not a wild animal from Africa. Sort of like a didgeridoo with a mouth piece.
Natty from State High was there too. We also saw Michael Coyne & Alistair Wuth
There were a couple of notable negatives.
This fellow, not easy to see in this photo was a camera operator who kept making a point of falling asleep. I found it very distracting. Megan gave him 'what for' at the end.
And the BGS boys seem to have decided that it is no longer necessary to do up their top buttons. Cane the lot of 'em Brian.

And now a bush dance.

Weekend In Stanthorpe
This is a bit of a draft.
More photos and video to add and some place names.
Here we all are after returning from a walk to ....

The Stanthorpe pyramid

These photos taken by Megan. Better than the usual fare served up by Frank.

Repair Soundcraft Sprit Powerstation 1200 Powered Mixer
Note you do not have to remove the handles. Very handy to keep them on because it is heavy and it gets no lighter in pieces.
Fold the control surface back.
Then slide out the shield.
Inside. What a monster toroidal transformer.
This is the power amp board.
The silver thing with fins is the heat sink. You can see the fans behind it (Black).
The round things on the heat sink are the power transistors. (We assume some are blown to a short circuit condition).
The power transistors are:
MJ15024
MJ15025
Ordered some from Element14

Shipping Charge:
$0.00
GST:

Total:
$90.0990.09
DEBUGGING
1. With multimeter on the diode (beep) setting, measured between B-E, B-C, C-E on all the power transisors. On the left channel all seemed short (both the NPN and the PNP transistors) whereas the right channel did not.
2. Not knowing the designators of the power transistors, I have arbitarilly labelled them 1 to 16. (Left channel is 1 to 8).
3. Pulled out transistor number 1. MJ14024. Measured it on its own and blow me over, it's OK.
4. Measured the characteristics of some of the new and some of the [good] old transistors and there are small differences so as they are all in parallel I
decided to remove all 8 transistors and replace them with the new ones.
Working down the bottom of the heat sink fins is awkward and also the unit is dusty. I was worried about dust getting under one of the transistors are degrading the thermal resistance.
Upon closer inspection, the heat sink fins are screwed to the thicker plate to which the transisors are mounted. Removed these screws and removed the heat sink fins and a thermal gasket. This made it so much easier to clean and work on.

Soldered some power resistors across the fuse holders for the initial power up.
