…apparently not :-(

Seems like I should investigate how I could get my money back, just in case this little project goes belly up.

Drum roll…

I’ve just been told, we’d get a tracking number by tomorrow.

Yeah, well…

Today I’ve sent the next email asking where the “beef” is.

I am hoping to mod an x- y ploter for making pcb’s soon.
My 2uF is a very clever name.
Im studying EE by the way & I love it – Electronics rocks :)

For circuit boards try PCB International. They have a special for 2 layer 100 square inches for $94.99, they have free e-test and you can have multiple designs at no extra charge. They are manufactured in Taiwan and their quality is excellent. Here is their site: http://www.pcbinternational.com

It’s a curse. And it can only get worse in the future. Once jet fuel starts getting really expensive… I don’t want to know how long it would take if standard mail were transported by ship.

And there’s always our ever watching friends at the customs office.

You're right of course. The next one will have feed lines for both hot and cold water. BTW, I think your comment is related to this post ;-)

Where did you find a washer with no hot H2o feed? I am 60 years old and I have owned many washers. I also observed the washers my parents had and I gotta tell you that, going back to about 1957, ( I didn’t do laundry till I was 7) they ALL had hot AND cold water feeds. Rather than go through all those machinations, why not just go down to Best Buy and pick up a normal washer? SHEESH!

@robert

I just got my second light bar in the mail the other day and just finished playing with it for a minute or two.

Just to see some signs of life I put 12V with a 1K resistor on it and it did light-up (which I never got to see with the first one). Knowing now that it works I re-ran my initial test with no current-limiting resistor or current-regulated supply and started going up in 0.5V from 7.0V.

It did just what I’d expect it to do, starting lighting-up through 10V just fine. Just ran enough current through it to turn it on faintly.

I sent my first one back Dec 22 and as of a week ago, they still hadn’t gotten it yet. And we thought that them sending us stuff could be slow… the other direction seems worse.
