pointy needles flying about and instead of stunned amazement all we

ST ROFL! I think if you programmed it right, it would probably make one hell of a tattoo machine. ;-) Mark

I do too. But you gotta admit, for production purposes, that's a wicked fast machine. ;-)

Yeh. I certainly wouldn't want to stick my fingers in there whilst it's in motion.
Not really sure what all the things do in the video. Another electronics buddy of mine sent that to me.

Hello--
With a few modifications, this thing could revolutionize the tattoo
industry<g>.
I noticed that partway through, a larger cylindrical probe rapidly tapped on
what I'm guessing are the large SMT packaged devices while the needle
probes are flying. Possibly this is a test for intermittent solder joints
or BGA connections?

Brad AA1IP Brad, Not really sure. It was a link sent my way by another electronics nut. He said the same thing about tattoos. ;-) I want one though. <VBSEG> Mark

Re: TDS7104 hard disk dead and blank screen
An addendum, I grabbed the service manual from Tek's website, and it appears that the HDD and CD drive have both been removed (and probably crushed), including the specail push to latch carrier for the HDD. I hate people who do that.

Re: Need Source of Power Supply Capacitors for 7854
Stefan: The capacitor fit is tight, and the screw mount allows no slop - or there will be shorting to the chassis. I will probably have to try a dirty fix. So many of the old quality manufacturers have gone by the wayside. I have been in electronic engineering since 1964 and I am as burned-out as all the defunct companies that provided quality products in my youth. Thanx for your thoughts.

Re: Tired of spending the entire day at the troubleshooting bench?
All this tells you is whether or not the board appears to have been made
correctly. If the product value is high enough, you still have to
troubleshoot the ones with out of spec measurements from the flying lead
tests. (If the product value is low enough, you just scrap the failing
DUTs.)
