If you managed to keep component-level repairs going this long, I'm impressed. It got to be so hard to get any information, let alone schematics, that it was a relief to take an early retirement opportunity 10 years ago.

The folks at Redmond will continue to write OS's that will keep you in business doing the networking and Windows related stuff for as long as you can put up with it. Think of the messes still hidden in Win7!

Well, I do LITTLE component-level stuff. MAYBE 4 hours a week on average.

It's all networking problems and some intermod chasing, work on outdoor warning sirens, phone system and phone line problems, things like that.

I do miss the challenge of making the broken RF or even audio circuit work again. Ah, but life moves on (and I WAS getting bored with it after SO many years).

 

I have admitted not spending enough time on my work stool,watched a lot equipment
go out of date.Moved into many directions all good,what a life.I going to run around
the block to count my blessings. Come back and start another reply. I will also bless
you guys with all my heart.

 

Back,I was going to complain about my right groin muscle,but it worked out.For
you guys that sit with swollen feet it may not be (diuretic) a little help with spelling
please.Ask your doc to check your blood pressure med,if you ask I will tell you my med.My feet don't swell now when I sit at computer at all.I went to doc and asked for diuretic,he said blood pressure combo. A few people around felt safe.

 

hye everybody, sorry for bothering all of u here. i would to ask for heLp from anybody here. i having a problem with my mini-project which i have to design a Round Per Minute (rpm) METER using 7segment display which it will count the rotation of a DC Motor. to count this rotation, i need to use an infrared sensor. all this is hardware are suppose to be controlled by 8051 micro controller. i got 2 weeks to make all this,,, could anybody here help me?? about the schematic, hardware and assembly language of the 8051 for this project.i am really having no clear idea how to fix all this thing in such time.

 

Blueevils,your project will get more views in general electronic chat.
Sometimes a moderator will move it for you.

I think the word you were searching for is "diuretic," a drug that makes you urinate more often to get rid of excess water. Coffee has diuretic properties.

 

I remember not having a computer when I grew up. I typed my reports on a manual typewriter. I remember when the college I attended got this new thing called the "internet"...

I turn 32 in 11 days...

I took a semester of Slide Rule in junior college... No joke!

Me too! I learned to use a slide rule back in high school. I still have my Post Versalog.

I'd like to learn how to use a slide rule, never did though. All these calculators can do the job in a snap, but then I remind myself that we don't always have calculators. I've found myself in various situations where I don't have a calculator to what I'd like it to. That's when slide rules and such come in useful!

 

I'll hit 66 in November. Been interested in anything electrical since early childhood. A family friend had a hearing problem and hooked an extension speaker to his TV and put it behind his recliner chair. I must have been about 7 and found that very interesting and wanted to know how it was done. Took a correspondence course in TV repair while in High School. After high school, joined the US Navy and learned radar and servo electronics. After military, went to work for a major aircraft manufacturer in the automated machine shop. Stayed there 32 years and retired. Got bored and went to work part time doing industrial repair bench work on circuit boards and servo motors.

 

Didn't NASA launch the first shuttles and perform calculations on slide rules?

I thought NASA had PDP-8/e's in the shuttles in the 80s.

During Mercury, Gemini, and Apollo I can believe the "slide rule calculations".

Come to think of it, NASA managed to do the moon missions with a slide rule, but to really screw up, it required a computer on a MARS mission.

Having serviced PDP8's, I doubt it. I bought my first computer in 1978, a TRS-80. That old machine was way beyond a PDP anything. The PDP also used a lot of plug in boards, which is athema to anything space craft related.

I don't miss core memory a bit (no pun intended) either.

39, Got started mainly in computers (commodore 64 / Vic20 /Tandy 1000, etc.) and programming in the early 80's, but that eventually got boring so I started taking apart other things to build stuff to connect and control via pc, now I pretty much delve into anything electronics, robotics, and mechanics. I have no formal training in any of these fields everything is self thought, now I do this stuff for a living also, I design software and hardware (including all electronic controls, and the actual mechanics of the machine) for controlling industrial automated machines. I love that aspect of my job to where I am not stuck with one thing........ Plus I design stuff that breaks stuff, how much better can it get?? lol

There are insights you get from learning slide rule that you can't get any other way, even if you never use one again. I still think they should teach it in math class. (I have a fair collection of vintage slip-sticks myself. )

My favorite example of that is this question: If you had a rope stretched around the Earth and added 3 feet to its length, how high could it then be raised uniformly from the surface?

I don't think they even teach number lines any more, much less how to set up problems and reduce them so they can be solved on a slide rule. Asking a modern student to visualize a fraction is out of the question.

Well im 13

I started electronics when i was 5 and took thinks apart always and re wired them.
Then at 8 i got my first programming book vsiual basic make a program now.
Then at 10 i made my first 2 programs (available at http://www.aklem.com)
and modified a remote controled car to be a ticket-giver
then at 12 i started linux, glovepie, processing, and c++
then at 13 (big year) i made a automatic firing rubber band gun (20 band capacity), a line following robot, a 3x3x3 led cube, a nunchuck reader, and im starting to design a 8x8 rgb led matrix that gets the weather, time, and date over serial... Also the pc code can be modified to get twitter updates etc.
