They do nothing. There is supposed to be an ultrasonic signal
generated by
the things that is supposed to repel insects. Good luck! In the clinical
trials, the devices did absolutely no good whatsoever. There are no
"force
fields", nothing that interferes with nervous systems, nothing of the
sort. It
runs on snake oil.

Oh, I dunno - when I had one running in the shop I had in the corner
of my brother-in-law's building, it kept him out most of the time. That
sufficed for pest control ... {grins}

I got tired of switching the leads of my DMM. Suddenly if dawned on
me that I can just set the power supply to 10.0V for exaample, and
read the current, and then divide the voltage by the current to find
the resistance. Like I put a resistance on the PS, it reads 10.0V and
the current is .018A, so 10 / .018 gives 555.6 ohms. Must be a 560
ohm resistor.

I turned my PS into an ohmmeter - FREE!

Hee-hee - Work smarter, not harder!

Of course, make sure the current stays low so the resistance doesn't
overheat. For low resistances use a volt or less.


Also, you must now consider the combined accuracy, of two meters, instead
of just one.

Yes it works, but, so do pliers on a hex-nut. Something about the
right tool for the job.
Click to expand...
Actually it works better than a DMM on low resistances below an ohm.
But hey, it's still more accurate than a 5% resistor.

I think there are basically two types - one with the heater, slowly

ultrasound waves that are supposed to fight mosquito's.

Amazing. The possibilities are endless.

Using a thermister you could turn your power supply into a temperature meter.

How bout a diode checker. If the voltmeter reads 0.7 volts its good (watch that
current limit).

I just tossed my Fluke in the garbage. Now lets see you turn your power supply
into a frequency counter.

Hi all,

I am a new ( well sort of ) electronics enthusiast and I would like to

getting into the design and building of my own circuits. I would like to
first construct them on my computer and test them there as well. Or
something similar?

Is there any software, specifically freeware, out there wich can run under

Thanks to everybody who choses to reply.

Nonsense. Bugs don't have ears. If you have bug problems, like I had one summer,
I recommend grabbing the vacuum cleaner and sucking them up. As I said, they
don't have ears, and you can even suck up those damned fruit flies that hover
over your bananas in summer. Those fruit flies have good eyes and are hard to
squish, but a vacuum cleaner? No problem.

vacuum cleaner is always at the other end of the house when you need
it.. By the time you've fetched it, plugged it in, and got it running,

just on that heating element note:

Here in brisbane australia we get ceilings full of mossies (mosquitoes) in
summer.

both raid and mortein make plug in heating elements onto which you put a
poison pad

some work for 8 hours, some for 3 months @ 8hrs a night. a simple timer
switch to turn on for 8hrs per night is perfect.

they clear the cieling of mossies in 10-30 mins and keep you mossie free for
all the time they are on.

they are supposed to work for flies too, but I have never noticed a
reduction in flies due to these strips.

You don't want to "short" the ring current, you want to open
the circuit and not let the ring current through to any ringers
until the CID has approved the number.

Relay should remain closed at other times to preserve normal
functionality of phone system.

I posted a question about a Radio Device awhile back... it simply had
a full-wave rectifier between TELCO and the Phone to prevent ringing.

This could be implemented with a relay instead of a slide switch to
allow PC control.

The Caller-ID mechanism *must* be on the TELCO side... I tried it
after and the CID data can not be seen.

If you short the ringer current, the phone line will go off hook, and
the ringing will stop. Then you have to fake the ringing sound to the
far end so they think that the line is still ringing.

So why don't you just get a box that does this for you? You can buy a
card to go into the PC from such companies as Dialogic.

Dialogic cards are quite effective, but pricey. I spent $800 on one
