AU Components

I was asked today what components you can source locally here in Australia.

Attached is a spreadsheet containing the components I ordered from Digi-Key and Mouser.

Everything else is available here in Australia (from Jaycar for example).

first you get the money...

Finished the power section today.

This was all pretty much by-the-book except for:
I had trouble getting the correct voltage range out of TM6/IC22; 5.01 - 5.35V rather than the suggested 5.25 - 5.75V. I completed the section and managed to tune the required 5.33V on J4 so I guess that will be OK.

Test results during construction:
  • power jack 11V AC
  • C3 14.7V DC
  • C5 15.1V DC
  • IC20 5.05V DC
  • C1 5.98V DC
  • J4 5.33V & 11.83V DC

Let's get started!
