Hello, I post this on this forum, because I have a request that’s I don’t find the answer on internet.
I want to make a stroboscopic lamp for my airsoft gun.
My electronics skills are a bit higher than basics.
I watched a lot of YouTube videos, but none was comporting a 3 led working under 5 V...
Pls can anyone help me to figure our where to connect Bluetooth module to this amplifier. Am just new on the DIY Bluetooth speaker project.
I will appreciate your kindly direction and expert advice.
Hi, all...
New here.
Fired up a recent circuit having S8050, NPN transistors. (BJT)
I could see it was conducting from Collector to Emitter.
Thought I did something wrong, so I flipped it around.
It still conducted. *&^%$#@! argh.
I can't have the circuit conducting BOTH ways.... and I don't...
[1]: Motivation
AC loads are everywhere around us because at least home appliances are supplied with the mains power. Therefore, we always face the situations that we want to have full control (dimming) over an AC load such as a lamp, a motor, vacuum cleaner … etc.
We should know that...
An FM transmitter is one of the most popular devices between electronic hobbyist, professionals and even non-technical people. In this article, we gonna learn to how to build an easy, stable and digitally controllable FM transmitter.
For this design, I have selected the VMR6512 module which...
Embarrassingly, it seems 'off-line life' has -once again- made 'liars' of us:rolleyes: -- That said, I can imagine no scenario preventing either of us returning to regular participation next week (i.e. that of Mon May 13, 2019).
In the meantime I'm pleased to have found made time for the...
An obstacle detection unit is an essential part of a variety of projects, such as robotics and security applications. The infrared sensors are widely used for these types of applications. The main drawback of some circuit designs is that the detection units are sensitive to the outside lights...
Almost in any circuit design, building at least one regulation stage is necessary. Two power supply design options are available, which are linear and switching. The linear regulators are easy to build but inefficient, especially when there is a high difference between the input voltage and the...
FM transmitters/receivers are one of the top favorite circuits of every electronic designer. An FM transmitter is one of the first circuits that an electronic enthusiast decides to build.
For this purpose, instead of using discrete components and building one of the traditional transmitter...

Yesterday, I was browsing old technical manuals on the internet when I came across the book that changed my whole life. I was eleven years old in 1949 and an avid sci-fi reader, inspired by the writings of Jules Verne and H.G. Wells. I regularly raided my father's private bookshelves to read...
Firstly, a visual comparison ('Real Fed' vs. 'Mini-Fed'):
And now a minute 'exploration' of bona fide Federal Standard Connectors...
