Make me some code..

[Kamikaze47]

My solution wasn't "significant modification"... It was 1 cut of 1 wire

Hmmmmm.... sounds like a quote from a bomb disposal technician

However, cutting one wire changes the circuit diagram so no money for you.!!!

PS. If you are a bomb disposal technician you might want to change your name to instill more confidence LOL

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

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.

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 ....
