I have a small question.

Can we build a project without these primary components? I mean just only with some interface components?

I don't see why not, but it's likely to be a fairly boring project?.

joseph@e-tech · 21st May 2008, 05:03 PM

my circuit uses 2 SCR's and 1 relay, the rest are the parts mentioned, can i use them?

Krumlink · 21st May 2008, 10:46 PM

Yes so long as it applies to the rules.

If I were to design a 'creative' way of loading data to the circuit, with, say, punch-cards, would the sensors used in the punch-card reader circuit count as an interface? What about a DC motor used in the reader?

Using limited components you must build the most imaginative electronics project. You can use any number and type of interface components (for example LEDs, Relays, Switches, speakers, mics, etc.), however you are limited to maximum of 4 transistors, 10 resistors, and 6 capacitors. You must have a decent amount of text explaining your project, any schematics and also a photo of the completed project.

was this the rules of this competition sir's

from the underline highlighted

we can use any numbers of interface components to be used as inputs and outputs right?

how about photo resistors to be used as input interface component will it be counted as 1 of the 10 resistors mentioned

thanks

Gayan Soyza · 22nd May 2008, 06:22 AM

Mmmm there have been a lot of new packages comes to the market which is quite doubtful what is inside.

There must be a list of interface components so the competitors can understand what to use. Otherwise this thread may be an endless thread.

V.T · 22nd May 2008, 09:14 AM

im sorry i may have missed the deadline date. so how long do we have?

--Edit--
Pardon my tired eyes
18 june it is

Its in the "Entering the Competition" section in the first post.

"Entries can be submitted by email. Simply send your entry to electro-tech-online@gmail.com before 18th June 2008 (6 weeks from this post) and you will be entered into the competition."

Yes

There are various types of variable resistors that might be used as interface components. They do not count if-and-only-if you use them as an interface component.

A photo resistor used as an interface component does not count.

It does not matter what is inside a package when used as an interface component. It will be counted if it is not used as an interface component. Be sure that interface devices are used as interfaces for your circuit.

As Nigel said earlier, use your common sense. A list would place limits on the contest that do not currently exist.

Diodes yes or no?

Just use your common sense, the idea is to keep the competition cheap and simple, obviously a diode or two isn't a problem.

I agree Officer.

By the way my project doesn't contains any primary components or any interface components.It was used in late 1870s which helped to many scientists.After hearing this line I have to shift to another modern project.

Anyway I'll do what ever you say Officer.

V.T · 23rd May 2008, 02:38 PM

you was going to build a ticker tape?

?

--edit--
Actually if it had helped scientist it was something along the lines of a system which dealt with numbers but I don’t know how far back the first calculator goes.

I think the "spirit" of the competition is to build something that requires electronics, this being an "electronic competition". A science project like a mechanical calculator or a device that measures the speed of light using a rotating mirror can be made electric by adding motors and such, but violates the "spirit" of the competition because they're actually science projects with electric parts added on. They don't really need the electric part to do what they're supposed to do. A device like an electromagnetic metal detector is very much with the "spirit" of the competition because such a device fundamentally depends on electronic theory for its operation.

So a project that uses none of the core components probably violates the "spirit" of the competition. It might still be an amazing project, but it would probably be a glorified science project rather than an electronic project.

Anyone can probably submit such a project, but i'm sure the judges would take off a LOT of points if it violated the "spirit" of the competition.

Common sense once again applies. The internet can run on birds (look for "IP over avian carriers" in google) but electronics make it practical. If electronics are needed to make a project work then its probably acceptable.

Example: Beer cooler that uses a peltier unit hooked up to several car batteries. Requires a feedback mechanism to ensure the beer is always at the right temperature. Could still be done with a simple ice-pack but electronics give you that precision control for just the right temperature.

This is what i think the competition is about, Judges tell me if i'm wrong and need to retool this post.
