VLOG. Fake security camera made with 2 transistors, 1 resistor of 1 M, one 1 uF electrolytic and a normal RED led + 2 batteries of each 1.5 Volt = 3 Volt.
Schematic of the showed 2 transistor LED Flasher is here
https://youtu.be/xydI5tOjni0
Used: a NPN transistor with a high Hfe (the BC 547 b, Hfe is say 300) and a PNP transistor with a high Hfe (also say 300), the BC 557 b.
This makes a minimum components RED LED flasher (normal Red or Green LED must be used, no white or high power LEDS).
Works surely 24/7 for 3 months or even longer (tested) with 2 fresh batteries of 1.5 Volt in series, so together 3 Volt.
Was tested from March 2022 to May 2022, during 24/7. My assessment is that it can even work longer, say 5 to 6 months with 2 fresh batteries of 1.5 V each in series.
In this video I (thus) show how you can implement such a very simple and tiny circuit to make something.
My You Tube channel trailer is here: https://youtu.be/xbgQ8T3oqh4 When you search, search always “NEWEST FIRST” to get the right overview. You can also search via the “looking glass” on my Channel trailer via keywords like ”audio”, “radio”, “amplifier”, “filter”, “Shortwave”, “transistor”, “FET”, “oscillator”, “generator”, “switch”, “schmitt trigger” etc; so the electronic subject you are interested in. My books about electronics & analog radio technology are available via the website of "LULU”, search for author “Ko Tilman” there.

I keep all my YT videos constant actual, so the original video’s with the most recent information are always on YouTube. Search there, and avoid my circuits that are republished, re-arranged, re-edited on other websites, giving not probable re-wiring, etc. Some persons try to find gold via my circuits. I take distance from all these fake claims. I cannot help that these things happen. Upload 28 May 2022.
