Op Amps:- Why Are They So Useful
In this video I take a look at why operational amplifier, or op-amps are so great and so useful.

A scan of a series of vintage product labels from "Digi-Key Corporation" electronic components. They're calling themselves DigiKey now, but these are from 1997. There are 5 labels comprising 3 different styles. Two are red text on white card, for 5-packs of half-watt carbon-film resistors, one of which is labelled 330 ohms, while the other is 2.2 kiloohms. They also contain the specification "1/2 Watt, 5% Carbon Film Resistors", as well as the company name and the colour-band code for each type spelled out as words ("Orange Orange Brown Gold" and "Red Red Red Gold" respectively). Two are black print on white paper labels. They give similar information, but are in a more modern and boring format, with a barcode and stocking number. These are 470 ohms and 10 kiloohms. The remaining one is from a bag of 200 1-kiloohm resistors of the same type. It has little information on it other than the basic specs.
I can safely say that it's been a while since #DigiKey sold #resistors in pre-packed bags of 5 with included card labels. As their own brand. Made in Taiwan.
Or called themselves "Digi-Key Corporation".
More seriously, I found a bag of #components left over […]

A circuit schematic diagram for the Boss HM-2 "Heavy Metal" guitar effects pedal. It is fairly complicated as far as distortion pedals go, containing 6 operational amplifiers (opamps), 10 transistors of various types, and 4 potentiometers. I don't know what goes into "good" alt text for a schematic. Shown here, the input signal enters at top-left and exits at the lower right side of the diagram, as is customary. In addition to the actual signal-processing path, it also includes a power supply section supporting 9V battery or AC adapter and which generates a 4.5V bias voltage in addition to buffering the power supply. There is also the traditional Boss "soft switching" which routes the signal either through the effect, or via a bypass to the output.
This will be slightly #geeky, and probably only of interest to #electronics hobbyists and #guitar players. I happen to sit in the intersection of that particular #Venn diagram.
When I was a teenager, having only been playing guitar for a few years, I owned a […]
