Silly Job Title: Circuit Sorcerer. I am the Circuit Sorcerer!

In this video we assemble the CD4017 Colorful Voice Control Rotating LED Light Kit Electronic Manufacturing DIY Kit Spare Parts Student Laboratory.

The notes are on the wiki, over here: CD4017 Colorful Voice Control Rotating LED Light Kit.

I am planning to come back and review this circuit again in future. I have three spare kits and I’d like to understand the circuit better, particularly the filter and how the transistor controls the clock signal.

We use the METCAL PS-900 Soldering Station to solder.

We use the AiXun H314 Hot Air Gun for heat shrink.

We use the MUIN Solder Fume Extractor to clear the air.

We use the Tenma 72-10505 Bench Power Supply to provide 5V for testing.

We use the Fluke 17B+ Digital Multimeter to check our resistors.

We use the Bysameyee Head-Mounted Magnifier for magnification.

We use the Scotch Titanium Scissors for snipping.

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

We use the Plato Model 170 Wire Cutter to trim component leads.

We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

Silly Job Title: Electronics Guy. I am the Electronics Guy!

In this video we continue working our way through Learning the Art of Electronics and begin working through 1W Worked Examples: DC circuits. Particularly we design and implement the 1A ammeter. Next week we will do the voltmeter.

I measure the internal resistances of my various analog meters, which comes out like this:

Meter Resistance (Ω)
100 µA 2,271
1 mA 239
10 mA 27
100 mA 7
1 A 2
5 V 4,916
10 V 9,150
15 V 13,010

We use the METCAL PS-900 Soldering Station to solder our 222 mΩ resistor.

We use the AiXun H314 Hot Air Gun for the heat shrink.

We use the MUIN Solder Fume Extractor to clear the air.

We use the Riden RD6006 Bench Power Supply to provide test voltages and currents.

We use the EEVblog BM2257 Digital Multimeter to measure various things, particularly resistance.

We use the Sharp EL-546L Scientific Calculator to crunch a few numbers.

We use the Carpenter Mechanical Pencil to make notes.

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

We use the Plato Model 170 Wire Cutter to trim component leads.

We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

Silly Job Title: Current Curator. I am the Current Curator!

In this video we follow the instructions to build the Space Drop handheld computer game which you can buy in kit form from here: Space Drop Solder Kit.

The kit comes with the software preinstalled on the D1 Mini microcontroller, but in this video we replace the code with our own version of the code just to see if we could. And we could! Our code is here: Space_Drop.ino.

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

We use the Pro’sKit SS-331H Desoldering Pump to remove the OLED screen which I accidentally installed without the spacer.

We use the MUIN Solder Fume Extractor to clear the air.

We use the Bysameyee Head-Mounted Magnifier for magnification.

We use the Scotch Titanium Scissors to chop up the packaging for scrap-booking.

We use the Hakko CHP 3C-SA Precision Tweezers for holding solder off cuts.

We use the Plato Model 170 Wire Cutter to snip off component leads.

We use the Kaisi S-160 45x30cm Repair Mat as our workspace.
