content: This video shows a simple method to make a high performance (low inductance) socket to connect your oscilloscope probe to your circuit under test. It is easily adaptable to different probe sizes/styles and circuit configurations.

content: A+ sure beats trying to hold the probe on a small via bending over the spring tip just right... while trying to finagle the scope controls with the other hand!

content: Oh man, I did not realize Bob did videos... I gotta catch up on that.For some great discussion on low noise measuring, check out What's All This Ground Noise Stuff Anyhow, p. 88 in this pdf:http://www.ti.com/ww/en/bobpease/assets/www-national-com_rap.pdfEdit: or go right to the original article with the same text but no picture of a probe in a coily socket:http://electronicdesign.com/boards/whats-all-ground-noise-stuff-anyhow

content: Thanks for the video! Inspired by this, I attempted to make some small loop tips for my probe such that the ground "socket" ended in a straight wire that would be a second probe tip, rather than soldering that ground socket to something. I had a lot of trouble with the plastic retaining ridge on my probe snagging the wire loops and deforming, causing the probe to have a loose fit. So I went for something stiffer, and ended up with a finishing nail. It was a lot more difficult to work to the correct shape, of course, but it holds that shape as I take it on and off.

content: Nice ground spring adapter. I've also used a paper clip for the same thing, as it holds it's shape well after being formed.

Gave me many hours of bathtime entertainment (yes, I have a TV at the end of my bath connected to an Apple TV, not bragging, recommending a similar setup, you can read and watch tech videos and take a soak all at the same time, my gf thinks I'm nuts but loves me anyway)
