Dave takes you through designing a signal overload detector circuit from scratch and then builds it up on the breadboard.
- Window comparators
- Schmitt inverters,
- Capacitor charging,
- Pulse stretching,
- Common mode input range,
- Tongue angle tweaking,
- .. it’s all here.

EEVblog made a SMD hand soldering tutorial. In the video Dave explains how to solder small SMD capacitors and resistors, all the standard size pitches for ICs up to a 0.5mm pitch, as well as some tips how to use large thermal pads, like adding thermal paste or preheating the board and the IC. [via]

What’s in a name? David L. Jones of EEVBlog thinks he’s found an Easter egg in the performance characteristics of the 555 timer chip which reveals the basis of the “555″ in its name. Build his circuit (schematic at video 13:25), fire up the scope and see if you agree!
