Hi, I am ika n interesting to learning about electronic sience n instrumentation....now i am just still studying electronic to get bachelor in electronic. I am very hope at this forum can adding my knowledge about electronic sience ....

 

Hello,
I'm Lawrence and I'm slowly getting back into electronics after a 15 year hiatus from the profession. A lot has changed since then. My years are varied with solid state and tube electronics. My last 15 years were in the I.T. industry which revolve around Linux and BSD OS's. Now I'm finding myself more in micro controller circuits which are new to me. I hope to learn more.

 

hi every one im Umindu and i very interested in things ELECTRONIC i recently started working with Arduino and literally started to make rc Planes.and yes I am just 17 ans still go to school i live in Sri Lanka.I always do, some research and experiments with circuits like to build cool projects and be cool and educated

Hi, thanks for accepting me in. I'm in the M&E field, learning electronics and is passionate onto audio gear modding and upgrading.

 

Well I suppose I should get my whois in here.
I am the one who can not spell, will flip letters and even whole words around as I am typing. I never have a clean keyboard, usually you could have lunch from the droppings it would create, possibly dinner... not sure on that. I am also the one who realizes that he knows nothing and so has to go and try it out, no matter how dangerous it is, (they are still looking for that small town in Iowa I used to live in) and will not give up and try again until I get it right. I guess that is how my favorite phrase came to be an answer to can we do it? and I always reply of course we can! "It may cost Millions of dollars and thousands of lives but sure it is do-able) And never ask me if that wall is in the way, because I will be happy to move it for you, just need to find a new source of C4 is all So before I took my retirement from Medical Electronics Engineering (non degree) I had my fun playing with ways of blowing things up for test purposes. I really loved going to UL (Underwriters Laboratories) to do new testing. They even have a big FIRE ROOM!!!! is perfect for marshmallow roasting, the 12 foot diameter kind. Oh boy you can really melt things down in there.... sneak a few other things like the Managers desk in and test it!!!
Anyway I am from Iowa, now living in Colorado where there seems to be NO ONE!! that has a clue of what an electron is let alone how to hook up a light switch. So as I go slowly mad here in the event horizon of the largest black hole in the universe (this is where the universe will begin its end) I am pulling out all my old toys and beginning to play again with this fun part of science. Hooking up caps backwards just to see if anyone is sleeping , or heck maybe turn on my power amp and cause a city blackout.
My background was in Solid state and tube theory, focusing on magnetostrictive designs for ultrasonics. I never really got to play with the new stuff, ( I Was deprived!!!) so only picked up a little digital and even was (exposed) to a microprocessor. That about sums it up on whois here. Really nice forum here and glad I fell into this place. (INCOMING!!!!!!!!!!!!!!!!!!!!)

Harlan :blink: :unsure:

My whois.... I am retired also Harlan. I just retired last year. Was a little skeptical about retirement. Concerned about loosing my weekly engineer's exposure to other engineers and keeping up to date (as much as possible) with the technical fields. I was living in the Wash. D.C. area and worked for a very fine Defense related company in the DC area. I loved the hardware engineering aspects of Information tech. projects. Did some software (embedded) engineering as well. My most interesting jobs consisted of embedded processor projects with 8, 16, and 32 bit devices to do data concentration. I too am in an area now that is pretty rural and techies are hard to find here. Most people are farmers and fishermen (I'm not complaining, they are fine neigbors, and are friendly to a fault).
So, I hope to find that this 'All about Circuits' site will help me fill in the hole that has been left by my retirement. I am currently designing an ARM 7 based system to keep my skills sharpened. JimH...

 

Hello everyone,

I'm Nordine a french guy, I'm in electronics Engineer specialized in Analogs Electronics/Telecom. I am focusing on the Asia Pacific area for my career I'm working in China (Shanghai) now.

I have an excellent background in electronics and high technology product development. I have learnt to design, model, simulate, optimize the Hardware design and measure automotive systems and components.
Also I have had opportunities to work for PSA (French Automotive brand) in Sochaux/Shanghai during three years, in the R&D Department, mostly checking the electronic architecture, the selection of components (BOM) along with design and development of mechanisms.

 

Hi
Me Maria
I study an instrumentation and control engineering
and now am at the 3rd year

 

Hey! I'm John, and I have no formal education in electronics or EE, and am a networking and computer guy. But I am also a tinkerer and love figuring things out, so I've been playing with PCBs and building demo boards for a few months. I also do ham radio stuff, which can involve circuits and electronics, and actually learned a majority of my knowledge about 'How Circuits Work' from the Amateur Radio Handbook. Have I shocked myself: Yes (more than once), have I lit things on fire accidentally: Yes (learned a lot about capacitors), but have I learned a lot and somehow stayed safe, yes. And don't worry, all of that happened in a safe area, so it wasn't super dangerous.

 

Then this is your kind of site. We tend towards an eclectic taste in circuits.

 

Hi, i am Lassnas and new to the forum.

 

Hi everybody,

I am an Italian student of mechanical engineer at Politecnico di Torino.

 

I'm a 2nd year student in University of Birmingham, stream MICROELECTRONIC.
Mechanical is one of my favorite path.
My every time motto is TRY TO DO SOMETHING IN NEW TO WORLD!!!

 

Hi, I'm Amir, an Electronic Engineering Student at State University of Jakarta.
Nice to meet y'all.

 

I'm currently an electrician at one of the 3 remaining permanent magnet factories in America. Been there 9 mos. My background is primarily electrical/instrumentation and controls in power generation and semiconductor manufacturing. We've got a lot of ooooooolllllld equipment with little or no documentation. For example, I bought schematics for a Blanchard vertical grinder: It was drawn in 1936. That sucker still runs and there have been few modifications to it!

All the old timers are that worked there for decades are gone so to understand this old stuff I often have to reverse engineer it, especially our heat treatment furnaces. We have lower temperature (around 1600 deg F) hearths that utilize inconel "rod overbend" elements. They're fed by Scott-T 3ph/2ph transformers I had never seen before: 3 wires in, 4 wires out to drive two independent series heating element circuits. A 3 pole contactor feeds the Scott-T. Simple enough.

Then there's the silicon carbide "globar" hi temp units (2600 deg F) that threw me a curve ball. Turns out they take 480 vac single phase, send it through a 50kva saturable reactor with 2 coils 180 degrees out of phase to each other then it feeds a step down transformer that outputs a single to 12 series/parallel globars. A temperature controller regulates a 10amp rectifier that provides saturation current for the reactor coils to regulate current & voltage to the globars. Works like a charm.

I've worked on a lot of modern digitally controlled equipment that's a lot more complicated and a whole lot less expensive but there's an elegance and simplicity to this old stuff that might I find quite appealing. It's like working in a living museum.

 

I am in final year of BEE in kpk uet peshawar,pakistan

 

Hi, I'm Max, I completed my computer-science course long time ago and decided a new level of career that's why I'm currently a student taken up mechanical engineering and everything is new to me again. I wondering if you guys can help me especially on my electrical subjects. In regards with recent technologies such as windows, linux and mac platforms I'm still up to date, mostly I work as a freelance web designer and developer drop me message I might be able to help in these topics (if any).

Thanks again guys. Thanks for the warmth welcome.

Cheers;

 

And here it is...

Welcome Aboard!

 

Hello, I'm studying Music Industry Studies in New Orleans, and through my recording classes got interested in audio electronics. Don't know much yet but I'm beginning to bump up on my electronics knowledge and shop around for tools n stuff. Hopefully I'll be getting started on making circuits and wacky sounds when I get back to the states. (currently spending a semester in New Zealand).

Thanks for the welcome
