Replace the 470 µF capacitors with 10 µF for a very fast blink (flicker effect) or with 1000 µF for a slow, "police beacon" effect.
Long before smart home hubs existed, hobbyists used discrete components to automate their surroundings. Look out for:
Here is the modern substitution guide:
While digital technology changes rapidly, the laws of analog electronics remain identical. This PDF serves as a masterclass in discrete component design (using resistors, capacitors, transistors, and diodes). 500 circuitos practicos parte 1 pdf
In an era dominated by microcontrollers like Arduino, Raspberry Pi, and ESP32, it is easy to wonder why analog and discrete component circuit books are still so popular. 1. Mastering the Fundamentals
Essential for technicians working on vintage electronics or legacy radio equipment.
It teaches how individual components (resistors, capacitors, transistors) interact without the "black box" of modern microcontrollers. Replace the 470 µF capacitors with 10 µF

Never solder a vintage circuit directly onto a permanent PCB. Assemble it on a solderless breadboard first to test component tolerances and make adjustments. This PDF serves as a masterclass in discrete
Interfacing with the physical world is a major highlight of Part 1:
While it will not teach you advanced PCB design or IoT, it will teach you
The book's title promises exactly what it delivers: 500 practical circuits, though they are distributed across the entire two-part series.
