Here is a brief update on the portal turret. I’ve talked about it at each open day but I’ve finally designed and 3d printed a reflector that matches the new LED array to the Fresnel lens and LCD.

Side by side you can see the extra length required match up with the new LED.

Coating the inside of the new reflector I’ve done some quick tests in a bright room and the output seems considerably brighter but the real test will be when it’s all bolted back in the turret frame.

Next task shall be relocating the HDMI connector and fixing the LED array and heatsink permanently to the projector housing.
