Wiki now has a WYSIWYG editor

[Angus Gratton]

Hi everyone,

The wiki at http://hackmelbourne.org/wiki now has a WYSIWYG graphical editor for page content, so using wiki syntax is now optional.

Thanks to Tim for suggesting this possibility. :)

Please check it out! Let me know if anything seems to be broken, or if you have questions about editing the wiki.

That's AWESOME! Thanks hugely for putting that together.

Hi Everyone,

I was wondering if anyone here has experience in making transformers (photo below).    I need 220V to 28V step down transformers, 400VA.

The current company I buy transformers from is going out of business.   Getting metal pieces laser cut and welded should be easy.  Happy to invest in a small transformer winding machine.    Before I burn lots of calories, want to know if this is a bad idea or a really bad idea...

Thank you!
Ken

Hi Ken, are these transformers for your own use or are you selling products with them in it?

If selling they will need to be certified and that can be a little expensive.. My suggestion is you find a local manufacturer 

http://www.southernelectronicservices.com.au/   In Dandenong

Or Dyne industries in Bayswater 

http://www.dyne.com.au/

I have used both these companies before and they make good quality products.

I think it will be difficult to make your own as you will need to get the laminations for the core and you will most likely need to dip them in high temperature laquer 

There is a lot of testing required to be sure they are safe.

Hi Everyone,

I am looking for someone who can help me write example sketches and course notes for an Arduino kit that I put together for my son’s primary school.   I have been planning on doing this myself for the past few months but find myself with limited free time.

Work to be done at our factory in Heidelberg Heights in December and January.   $22 per hour inclusive of superannuation and work cover (if you do not have an ABN) –  I think this would suit a high school student with experience and interest in Arduino.  

If interested please send me an email.

Attached is overview of the Arduino kit.

Kindest regards,

Ken Ihara

If you really want a local bespoke fabricator the ones John mentioned
are good and have been making solid products in Australia for ages.

Here's another off-the-shelf 450VA 28VCT transformer which may be an option.

Or possibly Hammond 182R30 if you want a toroidal.
