Competition #1: Most Imaginative Project

[jpanhalt]

Thanks for the clarification, 3V0.

Examples of how a capacitor or inductor could be used as input devices are as various sensors (e.g., volume, pressure, distance, field). Resistors, too, would fall in that category.

I think the distinction of I/O vs. circuit proper is workable, although nothing is perfect. John

 

[Nigel Goodwin]

Nigel can best answer the question about diodes and inductors. This contest is his idea and he is showing interest, so I will not speculate.

Really it's a matter of common sense, bearing in mind it's going to be judged, and anything which the judges consider are 'bending the rules' is going to result in lower marks.

Remember, the idea is to keep it cheap and simple.

You can use LED's as as indicators, you can not use them in your circuit as a stand in for other diodes.

what does that mean?

 

[3v0]

what does that mean?

It means that LEDs are interface components when they are used as indicators.

 

[Torben]

It means that LEDs are interface components when they are used as indicators.

. . .or as sensors?

and if they're not going to be used as indicators...then what?

Nigel said to use common sense regarding the rules. That encourages innovation which is good.

Any 'problems' can be sorted out between the judges in the private forum.

 

[Pommie]

I think it could be interesting to see what people could come up with as "interface components", maybe this could be a side competition. Does Vf of an LED vary with temperature?

Mike.

 

[shokjok]

My innovative circuit uses two relays and five switches, and is within the parts limit set in the rules. I built it 21 years ago, and it still works to this day. I will put it to temperature testing this summer, to determine its coldest allowable operating temperature - going to the Rockies.
Not a simple circuit, and without intellectual property protection.

 

[Gayan Soyza]

however you are limited to maximum of 4 transistors, 10 resistors, and 6 capacitors.

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]

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

 

[Krumlink]

Yes so long as it applies to the rules.

 

[leetlumberjack]

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?

 

[Master scientist]

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]

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]

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

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

 

[Gayan Soyza]

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."

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.
