I also experiment with small-scale LED lighting.
Today I converted this standard 7&1/2 watt
bedside nite-lite lamp to a 12Volt, 90ma LED
type, using 2 TL78L06 Regulators and 12 T-
1&3/4 White LED's. Having the lamp on a hot
stand-by battery greatly reduces my risk of
injury during middle-of-the night power
failures, as I have to get on an oxygen tank
and off the oxygen concentrator when the
power goes out.:eek:

snipped........
90ma at 12Volts is less than 1.5 watts.
Woo-hooo!, a lotta' lite for the buck.:D

Earth-friendly lighting that rocks.:happy:

Hahaha!!!, those Panasonic WM-61A's got here today, and
DAYUMN!!!, they sound great. Tell ya' what, though, you
gotta' have Quaalude-steady hands to solder wires to
those tiny, little 6mm diameter "puppies" and virtually any
normal soldering iron tip will severely engulf the solder pads
on the back of the mic capsule and solder-bridge the
terminals. Oh, but they do sound great. Good thing I got
20 of them. Gonna' be a lot of new studio-quality mics at
Tenn Loop Ranch. My Kiddo will be here near the end of
this month, and, no doubt, some are going back with
him to COS!:D:bow:

A WM-61A-based microphone With 28 db self-noise
($14,000 mic's have about 16db.), this geeky
$15.00 contraption has a frequency response as
shown in the attached graph. It's 12db more noise
than multi-kilodollar studio condenser mic's will never
even be heard, unless it's being used in an anechoic
studio room! Most of us Dimmers will never use a
recording studio. This microphone is built from 3/4"
PVC pipe, household materials, and a couple types of
adhesives. A tiny piece of *perf- board serves as the
mic capsule mount. A single drop of RTV silicone glue
mounts the mic capsule to the board, while providing
a phenomenal degree of handling-noise rejection.
Hahaha!, ^#*()(&**!!!, soldering the wires on that
6mm diameter capsule is like trying to solder wires to
an aspirin!:eek:

This microphone is pre-wired to feed
the mic input of a computer sound
card.

*That tiny piece of perf-board qualifies
this device as a work of perf-board
piracy.

My newest VLF Receiver is very inexpensive, small.
light-weight, and uses any device with a stereo
electret mic input(PC, Digital Voice Recorder, etc.)
for power and for most of the amplification. A mild
hi-pass filter and variable loop loading resistance
give this receiver a delightful degree of hum
rejection. Wolfgang Buescher's Spectrum Lab, a
free download, will allow your Computer to filter
out hum and interference to near wilderness
levels!

The loop can be supported with a variety of non
magnetic materials, so I built my demo version in
a cardboard box!

The most "dangerous" part is that only a small
amount of electronic knowledge and
construction skill are need to successfully
construct this device.

Okay found the link I wanted too. This is real, he is one of the best.

I started to get into flying 3D but parts got too expensive.

Yeah, its amazing. Kinda scary when you think about the 2K+ in money tied up into one stunt heli and a simple miss timed moved will ruin it all.
That could be a high-risk spectator sport, too.:eek:

Flyin' like that, any day without human injury,
property damage, or an arrest, is a good day.:bow:

well I've had a few injuries but to be honest, all were my own fault. Fingers, hands, arms have all been torn up but lucky for me just minor stuff.
