Re: Producing and Marketing Electronic Inventions
Externet, I love the idea of the clear pipe, but do you think the plastic would dissipate heat properly? I wonder if I could mate a clear lid on a metal pipe?<p>I also like your idea with the reed switches. Though I wonder if a 4 key membrane pad mounted on the outside would do the trick as well. I'...

Re: Producing and Marketing Electronic Inventions
Thanks for all the help guys.<p>Those 1590Z cases look good for low-volume productions. But I can't seem to figure out a good way to drop in a pot, two push buttons and a small LCD display, while keeping the watertightness.<p>Any ideas?

Re: Design Software
Have you thought about using "Print Screen" screen captures, and pasting them into a photo editor where you can "Save As" a jpeg? Depending on the sizes of your designs, this may or may not be suitable.

Re: Producing and Marketing Electronic Inventions
The packaging I have in mind would be similar to a tobacco can, maybe a bit smaller. I was also thinking of going metal (aluminum) for better heat dissipation.<p>Also, the enclosure should be water-tight.

Re: Producing and Marketing Electronic Inventions
Up until volumes would make things too restrictive I would be prepared to handle the assembly between myself and other friends who are skilled in the business, and believe in my vision. The problem is, I need to develop an enclosure that has "the look and feel of simular items that are on the m...

Producing and Marketing Electronic Inventions
I have a number of electronic inventions that I'd like to market to a certain niche market. Obviously, doing so involves more than stuffing the electronics to a project enclosure as I have done with some prototypes.<p>How does one normally go about packaging their electronics to sell to the public?<...

Re: A little design help...
Sorry, I should have checked the 72V .55A rating (or 12V 3.3A parallel). I didn't think that a fan drew that much.

Re: A little design help...
After looking the electrical code, I'm appalled that there isn't anything to stop me from cutting myself in the heart and jabbing a 12VDC wall wart into it. Could a NC solenoid attached to the end prevent this?<p>Digitech, you definitely make some good points, but I think a friendly reminder would h...

diy guitar effects
Is anyone else out there into making their own guitar effects/circuits?<p>I just finished building a guitar amp out of an old car amplifier, a junk computer power supply, an old set of speakers and some scrap wood. I designed the preamp myself to customize the sound. <p>It sounds at least as good as...

Pay more for green energy?????
Who among us 'would be'/'is' willing to pay more to their utility for green energy, and if so how much more?

Re: Power factor correcting capicitors?
Billdar,
While I don't agree that we can replace existing power sources at the same demand levels, I'm very interested in the technology. Tell me more of the mag you put out, is it a technical publication?

Re: Power factor correcting capicitors?
Crowbar: There isn't near enough reactance in a house to save any money. While I've never seen it measured on a house, the power factor on your average residential substation is usually quite good, about .95.<p>Adding caps for voltage reasons though, is another story. However, your utility company s...

Re: Power factor correcting capicitors?
"Correcting the power factor will not change your electric bill one bit. The power meter only measures "real" power, the out of phase component does not register. There are power factor correction circuits for motors which lower the voltage to make the load current larger relative to ...

Re: Triac Control Circuit
Back in college we had to construct a similar circuit. We were given a circuit diagram, but if we could design our own we were given bonus marks. My circuit ended up taking about half the bread board real estate as the circuit our instructor gave us, and it seemed to be more reliable.<p>I don't have...
