Welcome to ElecCircuit.com — Electronic Circuits and Mini Projects

I have collected lots of electronic circuits and projects. They may be useful for learning and making a hobby.

I do this site full time. It is a hard job, use much time and a lot of energy like other jobs.

Though, I am not good enough at explaining Electronics in English. But some said that contents are useful. This is encouraged me to share Electronics with people.

And you!

My dear friend is a pleasure to greet you and express my best regards, Referring to this circuit, regulated supply 0-50V – 5A, the image is not very clear, if you please be so kind to give me a clearer picture. – As for the electronic components integrated circuits abound in the market. – Is a sink (aluminum) to the left of D2, has polarity and function meet. (Diagram below) – As for the diode D2 which would be the standard: 6CB11, 6GB11 6CBN is not legible in the diagram, what would be the equivalent (replacement) of D2 – SW2,… Read more »

Dearest momename,
your website is very interesting and potentialy useful, and your efforts and hard work are obvious. Personally I’m still learning much about component level electronic circuitry, and the explanations and descriptions are vital. It is obvious that you struggle with english, or at least your translator does. You might consider posting in english and another language which you speak fluently and can make accurate and helpful remarks in. Just let us know.

Thank-you for your site, and best wishes.

hello momename,
i am doing “4 digit sensor counter using mcs51-AT89C1051” as my project. It has been weeks i was looking for 1051 and i couldnt find it, can i just replace with it with other similar controller like AT89C2051 or NTE3100 with the same connections as u did?

Rudy

Thanks for all the (mostly useful) stuff you put on this website! It is greatly appreciated 🙂

Hi, I have a older Honda motorcycle that is running on a 6v system. Would it be possible to run a 12v dc lighting circuit using a step up transformer? Or is there a better way to go?
I would be very thankful for any information or ideas that you may have. Thank you

I want to say you that this site is fantistic
i want some tips to you for my mini projuct

richard

Watching your so called pro-amps, you use a cheap schematic, which is available on a large of forums on inet and ain’t build pro at all.
It allmoest looks like you’re a novice yourself.

I’m sure someone would be prepared to run through your site and correct the English – it can be quite difficult to follow what you are saying sometimes.

Momename:

Wonderful circuits! Good diagrams!
Readers can figure out what you want to say–based on your English level. Keep reading lots of English books and your English will surely improve.
You are doing a good job!

Hej Momename. Jeg sidder her og har prøvet at lave en Amp med 2 stk tipl 575 og 52 + volt og 52 – volt. Jeg ville efterligne den gamle Amp som jeg havde engang en starmaker 8041 mixer og det er her du nok kan hjælpe mig. Den på + siden tager signal, ok og den i – går ampærerne fra – til basis. Jeg håber inderligt at du kan hjælpe mig. Med Venlig Hilsen Ken Bjørn Nilsson. TAK
