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.

These are the lugs we use for the mains power wiring: 280pcs/set Cable Lugs Assortment Kit Wire Flat Female and Male Insulated Electric Wire Cable Connectors Crimp Terminals Set Kit (we use the yellow ones which are the largest).

This is the wire we use for output power wiring: 20 22 24 26awg ( 5 colors Mix Solid core Wire Kit ) Tinned Copper Electrical line Cable wires PCB Wire DIY (22 AWG).

These are the lugs we use for the output power wiring: 100Pcs 2.8mm 4.8mm 6.3mm Plug Spring Female Male Spade Cold Crimp Terminals Connector Car Speaker Electrical Wire Connectors Set (2.8mm, Gold-Male, Gold-Female, Sheath).

These are the M2 nuts and bolts we use for securing the transformer to the base: Total 400/650/1140/2100X M1.6 M2 M2.5 M3 M4 M5 304 Stainless Steel Hexagon Hex Socket Cap Head Screw Bolt Nut Set Assortment Kit (Set D 2100pcs).

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

We use the Fluke 17B+ Digital Multimeter to test the AC power output.

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

We use the Bosch IXO VI Electric Screwdriver to install our screws.

We use the Brother P-Touch D210 Label Maker to make labels for our project box.

We use the Scotch Titanium Scissors to cut open various baggies.

We use the Carpenter Mechanical Pencil to mark out where we will cut or drill.

We use the Hakko CHP 3C-SA Precision Tweezers to work with our small M2 nuts and bolts and other things.

  2. Fake; act like a motivated person and do the actions
  3. Uptime; spend more time on tasks as you get better at it
  4. Zone; make sure your environment is distration free, if you find yourself distracted make a note about what distracted you so you can remove it in future

This is a note for Future John. I followed the instructions from ChatGPT. They looked reasonable enough. Now I have a spare 2TB SATA drive that has no purpose in life. I am always sad when things have no purpose in life. Who knows. Maybe one day…
