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.

Silly Job Title: Joule Juggler.

In this video we make a project board for use in our Learning the Art of Electronics projects.

In the beginning I mention a few things which have arrived from AliExpress:

We use one of the ElectroCookie Large PCB Prototype Boards and attach female pin header and male pin header. The flux I use is AMTECH NC-559-ASM and my solder is Loctite (Multicore) 60/40 C511 5C 0.56mm.

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

We use the Fluke 17B+ Digital Multimeter for continuity testing.

We use the Horusdy Soldering Station with Hot Air Gun to try to melt our flux, unsuccessfully. It turned out the problem I was having with the flux wasn’t that it had hardened in its tube, but that the nozzle had become clogged. When I cleared the nozzle the trouble I was having dispensing the flux went away and the flux flowed freely.

We use the Hakko CHP 3C-SA Precision Tweezers to place our pin header.

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

In this video we have a look at an old book, the Student Manual for the Art of Electronics (find on archive.org). This old book references The Art of Electronics 2ed, but The Art of Electronics is up to 3ed now. In this video we just flip through the book to see what is inside.

This book is made obsolete by Learning the Art of Electronics 2ed, which is an ongoing project of ours.
