This is my first project I built when i started get involved in electronics.
I made this project when I was 15 years old at high school and it gave me the first prize at a national Technology Contest which took place in Cyprus.
Its a parrot cage which has an automatic food and water supply and...
This is my second project at high school when I was 17 years old (the first is the modified parrot cage you can see in one of my albums). To give you an idea what a Cyprus style grill is see the first photo below.
With this ordinary grill, you can only adjust the height of the meat on the...
hi i am new here. so i am not sure whether this is where I should post this question.
I am trying to design a circiut that eliminates the in rush current problem in Toroidal transformers. I have in mind a current limiting resistor with a time delay relay for 100-300 ms. Could some body help me...
With the remodel finished, and sundry parallel tasks complete or nearly complete, I decided it was time...
The "omen" telling me it was indeed time was an e-mail from Powell's advising me they had a copy of a title on my "watch" list. I had the discretionary income at the time, so I brought it...
Many web browsers these days have spell-checkers built into them, or can use add-ons to add spell-checking capabilities. However, this is not the standard set-up on the majority of web browsers in use (notably Internet Explorer).
All About Circuits has spell-checking built into the forums and...
Thanks to David for the info. I had heard of these jumper mods but hadn't the specifics.
Right now I'd like to replace the standby switch as I think its causing an intermittant cutout. Going through everything with a can of Deoxit would not hurt.
And I have a request into Peavey.
I have to have a certain respect for insects. Most of my electronic (paying) work has to do with them.
But they also cause the strangest problems - especially mud daubers. For persons not living in the U.S., mud dauber is a generic term for several species of wasp that use mud to construct...
Ha. I just build the power supply unit. It took quite longer than I expected it to. I guess Im not used to juggling the iron, the circuit, the component being soldered, and the solder. Too much to do, I used scotch tape as my 3rd hand. Lol. Anyways, a few fingers got burned, but the job got...
Well, I am just a technician, so maybe I just don't get it. Or maybe I want you to do the work, instead of me.
My experience leads me to believe that you only learn something by actually doing it. If it's knowledge, you read the material. If it's a circuit, you only get the experience...
So, I got my
--500 pack of assorted resistors,
--my unassembled power supply,
--LEDs,
--hook up wire,
--Switches (not the right ones :( )
--60/40 .032dia Rosin-Core Solder
--30 watt solder gun
--Breadboard
--Plastic organizer box.
Time to put everything properly into the box, clear an area to...
The very great deal of interest in obtaining greater mileage from gasoline through water electrolysis has been interesting to try to investigate.
I have had to dismiss most claims as pure hogwash, as the "science" behind the invention is either so garbled as to be made up, or else pure...
I order most of what I was looking for, but I cant believe how frustrating it is to wait for parts to arrive. Sigh.
Well, just bought the following items:
--breadboard
--a pack of LEDs
--a few slide switches
--the powersupply kit.
my main concern at this point is whether I bought the right slide switch. It wasnt a big item, only costed 1$ for a pack of 10 switches. I just dont know how Im supposed to figure...
Ok, So I think that I will start a blog on this project and later move it to a thread if it becomes a project that others might find interesting. I doubt this will be of much use to anyone but someone in a similar situation as I am: a student with a very limited budget, learning EE/CE.
Problem...
I followed advice and combined the articles looking at the D9.pdf on "free energy". Just follow this link - http://forum.allaboutcircuits.com/showthread.php?t=14396.
I'm not going to bother posting the link to this site, but while looking over the many websites that purport to having devices to...
I got a bit irritated by the claims for a particular device that is supposed to let one electrolyze water at a rate 1000 times greater than physics says is possible.
The article, the D9.pdf - http://pesn.com/2007/09/29/9500450_B...r_Plans/d9.pdf- is full is nonsensical claims. The electronics...
I'm a relative newbie to electronics. My interest is in audio tube amplifiers and tube guitar amplifiers. Back in the days I built a Dynaco PAT5-BiFet and 416 and now wish I had gone for Dynaco's tube amps instead. This is pretty much the limit of my experience. (I have some bugs in the...

I attached the schematics of the circuit (in pictures) except the power supply schematic which is just two voltage regulators.

Previously I blogged about the Socratic Project, a free project of worksheets and questions designed to support the material covered in the AAC e-book.
Recently the Socratic Project was fully integrated into All About Circuits, available from here. As per the original project the following...
