Default Wiring a Driver backwards



So I thought that I would post this, even at risk of perhaps looking a bit foolish.
Perhaps someday someone will do the same....get scared....and then read this post
Feel free to add any of your own stupid mistakes and how you solved them if possible.

This evening I went to hook up my brand new a140 from DTR
Soldered my wires to the driver.
Ran it on the test-load....set at 1A
Soldered my leads to the diode.
Connected it to the driver
Connected driver to battery wires.
Put battery in
Click
Nothing
Took it apart again to see if something had come un-soldered....All good
Batteries in
Click
Nothing
This happened a few times as I tried to sus out what was going wrong.
Finally I noticed......
I had soldered the diode to the wrong end of the driver....I was trying to run it backwards!!
[IMG][/IMG]

I cut the wires....re-soldered
put batteries in
Click

So the moral of the story might be:
Even if you do something completely stupid, don't lose hope...just try again
Hope this learns someone besides me

Don't feel that bad. I have even done that once or twice back when I was starting out. Never to the determent of the driver or diode.

Default Re: Wiring a Driver backwards

It takes years to get over making mistakes.. And you still
make one or two here and there. There is no end

The difference now for me is I think 10 steps ahead..

Craziest stuff happens when you get into doing every aspect yourself..
Everything becomes trial and error, the cost of mistakes become
greater. Wasted time and wasted parts.

Stick with it long enough, and it will tune the way you think

totally... i made some EL wire costumes this past halloween and each one with all the wasted material cost me about 200 bucks. and to make 3 it took me about 25 hours total. but now it would take like 3 hours each and about 50 bucks each.

I must admit, they look to be a worth while project..

Look at mistakes as a good thing. Its usually where
you end up making changes and improving...

What kills me is machining.. In the final stages
having something go bad, or overlooked in stage 1,
leads to an encouraged form of male pattern baldness.
