The Deer Head Project

[Otaku]

I used a white acrylic on my FCGs eyes. I mixed in some RIT whitener powder and got a nice bright glow.

Anyone know what I'm talking about?

How about Clearneon?

It goes on clear and is only visible under UV light.

I can wire the blue LEDs to have a resistor in line for 12 Volts (since that's the voltage of the wall wart with no load) and I can wire the UV LEDs to have a resistor appropriate for 9 volts since the wall warts voltage drops to 9 Volts under load.

Good thing I ordered extra relays and screw terminals from Digi-Key.

Do you need 9V for the LEDs? If not, you could put a voltage regulator (5V perhaps) inline with the LEDs.... That would give you the voltage regulation you need as long as you can wire the LEDs for less than 9V.

What I'm going to wind up doing is use a 9V regulator to regulate the voltage down to 9V to the LEDs and use a relay trigerred by one of the prop-1's outputs to switch between which LED spotlight is active.

How is this project going, Z?

Waiting for parts to arrive at the moment. Specifically, the 9v regulator to keep a nice steady 9v going to the LED spotlights. I expect this stuff to arrive on the 8th, which is Tuesday, I think.

Here's a look at the deer head under its blue lighting just after the UV leds kicked on. Now all I have to do is program the damned thing.

I am sad to say that the 9v regulator does not keep a nice steady current running to the LED spotlights. Every time one of the deer head's motors kicks on, the LED spotlights dim just a bit. At this point, I'm just going to live with it as it is.

That thing looks positively creepy! Love the way that eye stares at you.

that does look damn creepy, love the eyes too!

looks awesome Z.
