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.

Making A 2-Transistor AM Radio With A Philips Electronic Engineer EE8 Kit From 1966
I have a new post on Hackaday: Making A 2-Transistor AM Radio With A Philips Electronic Engineer EE8 Kit From 1966.
But what is a Laplace Transform?
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: Prime Hack. I am the Prime Hack!
In this video we take a look inside Encyclopedia of Electronic Circuits Volume 3 by Rudolf F. Graf.
Some circuits of interest included:
| Page | Circuit |
|---|---|
| 245 | Electronic Dice |
| 327 | Adder |
| 337 | Electrostatic Detector |
| 594 | On/Off Inverters |
Some things we needed to look up while flipping through:
CMRR is Common-Mode Rejection Ratio.
RIAA is Recording Industry Association of America.
RIAA equalization is a specification for the recording and playback of phonograph records, established by the Recording Industry Association of America (RIAA).
PUT is a Programmable Unijunction Transistor.
φ (phi) can represent an angle, typically the second angle mentioned, after θ (theta).
PEP is Peak Envelope Power.
For voltage signals you usually want high input impedance and low output impedance.
LVDT is a Linear Variable Differential Transformer.
NAB is North American Broadcasters. They defined phonograph standards similar to the RIAA’s.
