20250817 Spinner Front Mandible

Two and a half years. Yeah.

I think that was how long I last worked on the Fujimi Blade Runner Spinner. The Main Board was ready, until I realised the fancy screw-less connector terminals have QC problems which led me to redesigning it again. The orange tab would go all floppy which means you cannot connect or disconnect the wires reliably. And while I am doing that, I wanted to revisit the other two PCBs as well. And as usual, it took me quite awhile to figure out what I did the last time since there were no walk through notes but brief texts.

The Front Mandible

It is just me or is Harrison Ford still sitting on the left side of a flying vehicle which has a pair of front mandibles complete with a set of a long horizontal engine? Anyway, the front mandibles are lit up during flight mode and there are three areas of lighting. Thinking about it, here are a few ways to light them up but in order for them to be uniformly lit, that would be a challenge.

For that, I am going to try with some 020 side view white LEDs and I have placed two per window. Hopefully, they will provide me with the uniform lighting I am looking for, with no cold spots. If this works, I would not have to cut out holes in the plastic but use them as diffusers. I hate to use those LED noodles which does solve the issue but to be honest, I am not sure how long they will last compared to a solid SMD LED. As for the side ‘dimple’, I would be using either a 3mm LED with a large electrode or, a 5mm straw hat, plus some silver paints.

This double-sided ‘universal’ design allows me to mount on the either side of the front mandibles. But at any one time, only 5 LEDs (per side) would be used.
This is how it would look like. Although the thickness is exaggerated, the actual thickness is 1mm. I think once this board works, the production version would be using White PCBs for better light spread. You know, I kinda like the three circles but years later, I would have forgotten why they’re there for in the first place; it’s to mark the ‘circles’ in the model kit part during testing for space for the components.
