Silly Job Title: Amp Alchemist. I am the Amp Alchemist!
In this video we demo the KY-002 Vibration Switch Module. There’s more info here: KY-002 Vibration Switch Module on ArduinoModulesInfo.
Source code is here: 2025-10-13-KY-002-Vibration-Switch.ino.
We use the Rigol MSO5074 Mixed Signal Oscilloscope to check the output signals.
We use the Riden RD6006 Bench Power Supply for power.
We use the EEVblog BM2257 Digital Multimeter to test voltage.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

FREE Analog Engineer’s Circuit Cookbooks from Texas Instruments
Today over on the EEVblog forum I learned about the two ebooks available from Texas Instruments. One is for amplifier circuits and the other for data-conversion circuits, including both Analog-to-digital converter (ADC) circuits and Digital-to-analog converter (DAC) circuits. I had to sign up for an account before I could download…

Silly Job Title: Chief Fuse Blower. I am the Chief Fuse Blower!
In this video we continue to work through our Maxitronix 30in1, today doing project #3: The One-Way Street. In this project we learn a little more about diodes and LEDs.
We use the EEVblog BM2257 Digital Multimeter to investigate voltages within our circuit.
We use the Sharp EL-546L Scientific Calculator to do some basic calculations.
We use the Carpenter Mechanical Pencil to make our notes.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.
