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.
