Silly Job Title: Switch Switcher.

In this video we build two circuits for Learning the Art of Electronics.

The pre-reading for today is up to and including page 18 of the course work. So if you have the book try to get that reading done.

In this video we test a circuit and its Thévenin model to see that they behave as expected. They do! But I’m still trying to get my head around all of the details…

I mention about my decade boxes. The good one is this one: Multicomp Pro MP701033 Resistor Box (I have ordered two more of these) and the crappy ones are these ones: Yum Cha J15026-2 6-Knob Resistor Box.

I also mention about the analog multimeters, this is the crappy one I have: Yum Cha MF-110A Analog VOM Handheld Multimeter and this is the slightly less crap one which I have on order: Pro’sKit MT-2207-C Analog VOM Handheld Multimeter.

In the video:

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

We use the EEVblog BM2257 Digital Multimeter to get our voltage and current readings.

We use the Riden RD6006 Bench Power Supply to power our test circuits.

We use the Brother P-Touch D210 Label Maker to label our circuits.

We use the Scotch Titanium Scissors to cut things.

We use the Carpenter Mechanical Pencil for writing our notes.

We use the Hakko CHP 3C-SA Precision Tweezers to do precision work.

We use the Plato Model 170 Wire Cutter to trim our leads and wires.

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.

Electronics Project #15: Making Project Board for Learning the Art of Electronics | In The Lab

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.
