Make me some code..

[Kamikaze47]

I wasnt saying it met the "contest" criteria, I was just pointing out that it didnt require "significant modification".

[T.Jackson]

New game - I'll pay AUS $25 to the person who can come up with the best DC to DC converter design. It should be low in cost, capable of producing at least 10mA @7V (~70mW of power) from a 5V source. Additional, desirable criteria in the design would include: compactness, protection, low component count, efficient, testable & robust.


<b>The Contest</b>
<ul>
<li> Submit in this thread, a workable, readable circuit diagram</li>
<li> It must be your own original work</li>
<li> You may submit ONE design only (no amendments allowed)</li>
<li> The design can't use a µcontroller or discrete ICs</li>
<li> A detailed description on how your design works would be beneficial</li>
<li> All entries must be submitted by the 31st of October</li>
<li> The Winner will be announced in early November </li>
</ul>
Oh! - and feedback from people on the entries will be highly regarded, and also possibly used in helping to identify the winner, so don't hold back!

What in software would create a collapsing field? if there was a relay coil across that led It can light.. not STAY lit, but light..

Most probably one could sell his or her own design at much higher cost than surrender for a Aus $20/-.

Hi, trent

Just use your OSC output to drive a common 1 transistor voltage doubler ... ( just need 1 NPN, 1 PNP, 3 resistor, 2 diodes, 2 capacitors )

Alain

PS : 25 $ for that ... ??? where did you learn electronics ????????????????????????????????

[mister_e]

mpfff, there's a load of missing informations to base something like a design around the previous requirement.

Regulated or not?
isolated or not?
Protection??? which?
Expected Output voltage?

etc etc etc.

25$ I don't think i can do something really reliable in less than 15 minutes.. or i'll lost money... as if i really need to lost anymore now

Maybe i should read the whole post again ?

Well, don't bother entering the competition then if you can't find the motivation for it - as simple as that.

[T.Jackson]

Ideally your entry will also include some firm documentation to support your idea. Some of the criteria that I'd like to see embedded in this document include ....

1. Statement of circuit scope i.e. (description, what it can do, constraints etc ...)
2. Specifications (rated output etc..)
3. Flow of events (how the circuit ticks)
4. Calculations, explanations i.e. (how did you arrive at certain values for components)
5. Any closing arguments that you may wish to add

*(2-3)pgs tops.

Thank you for your contribution, Alain. Some supporting documentation on your acclaimed working circuit would further improve your chances of winning.

Hi, Trent ...

You're joking, I do hope ....

I couldn't be anymore real, serious & genuine about it. This is an official contest to see who can come up with the best low-cost DC to DC converter design.

i WONDER WHAT IS OFFICIAL AND HOW IT IS OFFICIAL FOR A WEBSITE, when the OP is not the adminstrator?

whether now a days this website is permitting business on their site by anyone.
