My ad counter went crazy on today's +Daily Camera .  When I turned ABP off to see how it might look like my browser crashed. If anyone is reading DC with ads - what kind of setup are you using for this?

Tunnel diodes are awesome. There is plenty of Russian ones still available, they are good but the current is low.

[EDIT} Turned out this header is indeed the correct one for the receptacle. [/EDIT]


+Mouser Electronics is getting harder to deal with. They've sent the connector with wrong pin count so I contacted them. Instead of usual "sorry about that" and the item promptly overnighted they now request "pictures of what they received along with the Mouser labelling(sic)".  Taking a good picture of 0.4 mm pitch contacts took Canon 5DM2 plus 180/3.5L macro (very expensive), as well as several attempts. Wrong connector on the left.

All you need is a cell phone and a 3 dollar plastic 10X eyeloupe. I've done it before, just need lots of light.  Would easily be able to see the pin legs.

I get my cheap Chinese junk from www.mpja.com including said eye loupe (times two with built in LED light)

Mpja does kits, power supplies overstock bench supplies etc.. GREAT site.

I get my expensive Chinese junk from Digikey.
I never liked Mouser.

+Alan Wolke  Thanks for this info, I use this oscilloscope at work. Now I won't need to wheel over the Spectrum Analyzer as frequently.
