Tips, Tricks and Ruminations

As the title suggests, this is a place for tips, tricks and things to turn over and over in the mind...

  1. Of Things Sticky Tape...

    OK - so I have this rather heavy copy-paper cabinet that also was built to be a laser printer stand.

    I'm thinking, "Hey! This might make a light-duty safe - if I could lock it up somehow".

    With that, I'm off to Home Depot to buy the hasps, bolts and locks for the project.

    Everything was going along smoothly until I realized that where I had drilled holes to mount a hasp left me no easy access to add lock ...

  2. Of Things DWYGD #4...

    So I'm working at home one day and wish to pipe some tunes on the laptop over to my lab's audio system.

    This means that a conversion between 1/8" stereo jack to standard RCA jacks is required.

    What to do...what to do...?

    As had been said, "a picture is worth a thousand words" - well, maybe 999 in this case!

    What is it you say?

    First off, it's a blend of wood (plywood to be exact - ERCO!) and technology.

    Secondly, it's a demonstration of prototyping the [I]old school [/I]way. Yes, those are solder strip lugs!

    Thirdly, it's the prototype of an audio power amp with which I've been tinkering.

    The heart is a power op-amp from STM:

    So I find this nifty keen part from Maxim that should fill the bill to a tee.

    The only problem is it's in a [SIZE=1]microscopic [/SIZE]SMD package! :tongue:

    [ATTACH=CONFIG]91207[/ATTACH]

    What to do?

    Hack out a small piece of perf-board, thread in some bare 30AWG wire, glue the small-a$$ pack to the board, and carefully (oh, so carefully) tack solder the wires to the pads.
