Been thinking about a ‘coin plate’ (I use the term loosely) for the coin slot at the front of my cab.
After playing with some designs which had flashing LEDs and lit panels around the slot I had a
re-think. Then something caught my eye. Pixelhugger’s avatar! For those who aren’t familiar
with it (however unlikely) here it is.
The reason I liked it was because I was also inspired by something else the, glowing centre of
Iron Mans Chest, I thought about combining the two into a ‘Glowing Gear’ type arrangement with
a thick white PVC backlit centre powered with whatever LEDs are needed to achieve the right effect.
So firstly I asked Pixelhugger if he minded me using the basic shape less the centre rocket (cool as it ).
With his blessing I proceeded. His cabinets sport the logo in various forms, I’m happy to have the
recognisable shape on mine. It will certainly remind me of the inspiration gained from forums long
after the cab is finished.
Here's the concept..(Ignore the long object sticking out the front, that's a cutting guide for the coin reject slot).
So.....much time was spent coaxing the shape out of various materials and methods but the end
result is ok so far.
First I drew the shape as an object..and printed it out at exact size.
The stuck it to some very high density foam, cut out the shape and embedded into plasticine.
Put the plasticine in the freezer, took it out and removed the foam shape leaving behind a mold.
Mixed Plastibond up and poured into mold with this result....lots of air bubble holes....
Then followed firstly a centre hole cut, (using template guide) then some refining using Dremel tools
and sandpaper with some over coat of Plastibond into air bubble pits. Finally sprayed over with good
ol spray putty.. and test fitted with chrome collar.
The PVC centre was router cut out of 20mm thick white PVC (using template) and then
rounded off by mounting onto my drill press with sandpaper and Dremel tool. Some more finishing is
required as can be seen.
I’ll cut the coin slot with Dremel router bit later. Next post will cover LED wiring and final assembly.
My idea is for the unit to flash bright red twice after coin insertion, but normally glow white the rest of the time.
