Has anyone used conductive expoxy instead of solder
to assemble a PCB?  I currently apply Pb/Sn solder
paste, then pop the board into my trusty $29 toaster
oven for a couple minutes.  But now I am trying to

I got ahold of some green Liteon LTD5621AG 2-digit LED numeric
display modules but can't find a pinout diagram anywhere on
the web. I don't even know if they're common anode or cathode.
Rather than destroy some of them trying to find out I thought

Do they make any kind of stereo with everything in one compact unit?
ie...  unit, speakers etc....
Lets say you had a special need for this, such as a boat...

I have been working with huge companies (30,000+ employees) and in most
cases my tech's are on the same or in some  cases are on significantly
higher wages. I guess there are to many people who can design circuits these

Excuse me!!.
Would you stop for a moment?!
O...man...Haven't you thought-one day- about yourself ?
Who has made it?

I need to mount a 20 inch diameter by 5/8 thick G10/FR4 disk,,
(this is a high impact,fire retardent,high Rockwell hardness product)
I need to mount this to a 3/4 HP electric motor with a 3/4" diameter
shaft.

Can anybody point me to a good design of same.

Is there a simple way to re-use the motors from old hard drives... I assume
that they are some sort of DC / 3phase pulsed motor, but has anyone had any
luck driving them external to a drive.
They are easy to salvage, and I was hoping to be able to use some.

Howdy everyone,
does anyone know of a lithium ion cell supplier inside oz? I'm after
something around the 18650 size. 3.7-4.2v, 2000mAh or greater. Before
everyone chimes in, YES I know the charging requirements of a lithium ion

Assuming it is not too complicated.  What is in these things ...

Just been helping some students assemble some electronics projects:
We'd bought the Dick Smith branded "Digitor resin (sic) cored solder
type 35" and the Dick Smith branded "Super Solder Wick" cat No N2814.
To cut a long story short, neither product works very well: The solder
