Rather than attempt to make the Hydra battery first, I thought that the transponder would be simpler. I may have been wrong. The moral of the story is: don’t let a certain set of software skills sit unused for two years and then think it will all come back to you in minutes…
First, I gathered all available reference material, which sadly consisted of screencaps and professional and amateur auction photos. Nothing in the art book, no solid dimensions. So I guessed at the size based on comparing the width of my gloved thumb with the Captain’s. Then I scaled the images to match. Redrew the whole thing in Illustrator, then made some ‘blueprints’ for myself. Built it from scratch in 3D, with plenty of mistakes & compromises along the way.
Exported the final model, uploaded it to Shapeways, chose a material and ordered it. Ideally, it will ship out on the 30th of August.
In the meantime, I may try my hand at the battery. Problem with the battery is that it really has to light up for the full effect. The transponder doesn’t have to do anything.
