¿QUESTION? PC Power Supply?

Nawwwwww,

I must have some Dr Mengele genes. I wanna hear them SCREAM. if they did not slaughter for sport I would not feel this anger for them. I am truly German in heritage - the enemy must be defeated with superior technology.

doesn't Mexico allow pellet rifles ?

a head shot (right in the ear) with a pellet gun will bring them down
think of the varmint hunting your missing

:E :B

C'mon! Tell us how you really feel about possums! ;)

Gdetrailer how about DIEZ MIL GRACIAS!

I am using the 30 watt chips powered by 12 volt battery power (supply when available). Since the chips are 36 volt rated it takes a special (most limit out at 35 volts) DC to DC booster to make this happen. And space is limited. When I can find them I snag bathroom LED ceiling fixtures, remove the 16 watt warm white chip and replace it with the 30 watt 5K. The 120/24 volt converter is removed and a small fan is fitted atop which goes the DC to DC booster.

The height of this assembly is no stinky-bueno for RV interiors. But for outdoor use they cannot be beat. I cap the booster with a three sided project box. A 30 watt light, fan and booster consumes 34 watts. Not even 3 amperes of 12 volt power.

HOWEVER!

When I saw those nineteen ninety five outdoor 120 VAC fixtures, I purchased two. There's gonna be some surprised possums. Heh heh heh. 12 volt motion detector. Fires off a relay. Power goes to the Turbo fence charger, lights, and get this, a purchased yesterday THIRTY WATT 30kHz ultrasonic piezo transducer. One watt will deafen a human at say 2kHz. This transducer is inside a metal horn. The metal horn is aimed at a mesh of 4" steel wire, 3" off the ground. The possums have already stepped through it unelectrified trying to get at the hens. Wait till 30KV hits them, ultrasonic pulses that will shatter glass and intense LED light. Those possums kill for the sport of it. Wonder how a deaf fried possum is going to enjoy life...

$16 for individual 30W LED driver seems to be really skinny on the price.. Even dumpster diving on Ebay most likely is not going to get you anywhere near that not to mention the quality of being cheap may bite you in the behind down the road (electronic items are often not a good thing to be cheap on)..

To get better pricing you may wish to consider a LED and driver bundle (30W LEDS alone are going for $10-$11 so a bundle for $19.99 means you are getting the driver for less than $9)..

$19.99 for 30W LED AND DRIVER

HERE

$16.99 for 20W LED AND DRIVER

HERE

$9.99 for Warm White 20W LED AND DRIVER

HERE

$5.30 for 40A solid state relay heat sink which could be adapted to LEDs..

HERE

OR.. you do realize that you can buy an entire 30W LED 120V AC weather proof outdoor light fixture for $19.99?

HERE

The above has a constant current driver which accepts 85V AC to 265V AC, 30W LED, Heat sink plus an enclosure..

If you don’t like or want the enclosure you simply can remove the LED and driver and possibly cut off the unwanted extra material to use the back of the fixture as the heat sink for the LED..

I was hoping to get indidual 30 watt drivers for around 16 dollars. Chip, driver, heat sink add up to a lot of money.

Thanks for realizing I have truly lousy internet here with TelCel using the cellular. Looks like I have to abandon The Great Plan.

Oh well the Cheapos will work.

It's difficult finding a 120vac / 36-vdc converter that is very inexpensive. For LED lighting.

100W LED constant current driver (120V AC to 36V DC) HERE for $26

You can also get lower wattage drivers for less money or buy a bundle which includes driver and LED chip..

There are also add on lens/bracket/reflectors which you can get for $10 which concentrate and direct the light from the LED chip..

Would something like this work.

I have a 19" Insignia LED television, with one of those adapter cords. It is 120 VAC input with 12VDC 4 Amp output.

There was a thread recently about this where there was a link to a video where a guy made his computer power box into a DC supply. I tried it out and the wires that do 12v gathered together plus the ground wire have a steady 11.9v.

I don't know the amps it would do, but it would not charge a 12v battery for sure with that constant voltage. I had an idea for using it to power an old spare car radio in the garage but haven't got that far yet.
