Silly Job Title: Transistor Troubadour.

In this video we make some power cables which we will be using when we start to make the circuits for Learning the Art of Electronics. In particular we make two banana jack to DC barrel male and three DC barrel female to JST PH2.0 male. I also accidentally made a DC barrel male to JST PH2.0 but I’m not planning to use that.

The ElectroCookie printed circuit boards (PCBs) I will be using for the LAoE projects are these:

We use the METCAL PS-900 Soldering Station for soldering.

We use the EEVblog BM2257 Digital Multimeter to test continuity.

We use the Horusdy Soldering Station with Hot Air Gun to shrink our head shrink.

We use the Hakko CHP 3C-SA Precision Tweezers for working the wire.

We use the Plato Model 170 Wire Cutter to cut things.

1W 1% Metal Film Resistors

Today I purchased 1,200 1W 1% metal film resistors for my lab. Particularly I wanted a bunch of disposable resistors which I can use once in a soldered circuit which I will throw in the junk box when I’m done with it. The main application for that at the moment is my Learning the Art of Electronics project which I’m working on. I only had space for twelve varieties and I got 100 of each type. Being 1W rather than the typical 1/4W makes them a little more forgiving on the bench in the case of overload and the 1% tolerances keep things nice and tight. The values I picked include:

  • 10 Ω
  • 100 Ω
  • 470 Ω
  • 1 kΩ
  • 2.2 kΩ
  • 4.7 kΩ
  • 10 kΩ
  • 15 kΩ
  • 20 kΩ
  • 47 kΩ
  • 100 kΩ
  • 1 MΩ
