Upcoming calendar upgrade: Yahoo! Groups calendars are being upgraded to a much improved version. You may not have access to the calendar (for up to 24 hours) when this group is upgraded. We sincerely apologize for this inconvenience.
Description
|
A public access group primarily for Australian Electronics related subject material, but it is open to everyone woldwide.
Almost anything is welcome - Discussions, debates, news, rumours, questions (newbie to advanced), thoughts, opinions, circuits, tips, techniques, servicing, design, research, consumer, education, industry, jobs, links, personal classifieds etc
Doesn't matter what it is as long as it has something to do with electronics.
Spamming will not be tolerated and every new member is approved first to avoid spammers getting on the list.
There are lots of features to make use of, so please feel free to add useful bookmarks, create user polls, add events to the calendar, setup databases add to the FAQ, and do whatever you like. The more we all put into it, the more we will all get out of it!
Questions asking for advice on student projects without having done research first will not be well received. Please at least use Google first to try and find your answers before asking on the group.
Enjoy :)

Power Transistors
I'm wondering if TIP2955 and MJE2955 power transistors are the same thing but in different packages. I've been trying to construct a high current power supply
