Not content with 400 resistors, Dave ups the ante with several thousand genuine OneHungLow resistors, a semi-automated test jig, and some anger and love for the Agilent U1272A multimeter.

EEVblog #215 – Gaussian Resistors

EEVblog — Tue, 08 Nov 2011 06:22:55 +0000

Just how far out is that +/-1% metal film resistor you are using?
Is it just random?
Does it follow the classic bell shaped Gaussian response?
What are the odds of getting one that’s spot on, or right out at the limits?
Dave thought he’d find out, the hard way…

Usually no other content on there, just my video blog posts, so you won’t get bombarded with stuff.

EEVblog — Wed, 08 Jun 2011 23:44:06 +0000

Want to include a small Lithium Ion or Lithium Ion Polymer battery into your next project? It’s easy! Dave gives you the low down on how they work and how to charge them and select a suitable charging IC.

NOTE: For safety you should always use circuit protected cells as per the larger cell I was holding up. It protects against over-discharge, over-voltage, shorts etc.

(BTW, the reference to Lithium Ion Polymer being the same as Lithium Ion is in terms of charging, if that was not clear. The Ion Polymer type have polymer anode material and hence a different construction that allows the small pouch type cells shown in the video, and other thin odd shapes shown toward the end)
