Major Dome Holes Cut

I got a lot done this weekend. All the major/required holes are now drilled out and test fitting of all the bits that poke through.

Took my time on the last hole, the back PSI, as there wasn’t any room for error. I used the same hole cutter method as before but went extra slow and double checked all my measurements.

Rear PSI Hole

I also installed all the holoprojectors with some screws that go through the inner dome.

I still need to JB weld the screws in and I’m not sure if I’m happy with the result. I’m worried that the screws may eventually give out or pull through the dome.

I got to work on some of the electronics and made up some quick housing for the PSI circuits. Nothing fancy just some 1 1/4″ PVC pipe couplers and end stops/plugs. I cut down/sanded the plug make it easier to remove, and added a slot to feed the wires in. I also stuffed the tube with some bubble wrap to help diffuse the light. Eventually I’ll change the wire and hotglue the circuit board into the cap/plug.


I was anxious to do a full test fit of all the dome parts installed, so here’s a quick photo of th rear logic and a holoprojector installed

Here’s a test video of the rear logic and psi in action (ignore the wrong color on the PSI 🙂 )

Now I need to cut out the final outer dome panels and start thinking about painting.

I guess I also need to decide if I’m going to cut the remaining pie panels to make them open.

PSI Blinker Units from Fiber Optic Products

Just got the PSI Blinker Units from Fiber Optic Products.

This is somewhat of a warning, and time saver to others to get the right thing the first time. If you’ve ever tried to use their website you’ll understand my frustration and confusion. And their return policy is a nightmare to read. They’re email address also doesn’t work and they never answer the phone.

I’d ordered the Dual LED Blinker Unit based on recommendations on the Builders Forum


There’s two reasons I’m disappointed, 1) the flash/blink is not very accurate at all, and 2) the description reads like the flash rate was adjustable – but they’re not. Here’s the text from the website –

“The New R2D2 Unit will flash the Red Long, Blue Short, or Yellow Long, Green Short. The Duel-2 unit has adjustable speed for each LED. Please select color choice. DO NOT turn pot full or you will burn out unit!”

They have another well hidden page that’s the New Dual-2.

Newer Dual-2 PSI Board

I know I know, they say that in the text for the Dual but it sounded like that’s what I was ordering.

Boards look identical BTW – just a variable resistors/pots in two spots instead of a fix resistor, so I may try and swap them out if I can’t return them.

The only saving thing was that they’re were only $8.50 a piece.

I really should have just waited for the next PSI run from Dan.
