Animated Christmas Crab light

thingiverse

Animated Christmas Crab light. The Silhouette I used is attached but generated from a silhouette and fed through https://rasterbator.net to desired size. Print out, trace onto 3mm MDF, paint in a metallic paint (aluminium used here). The bushings for the claw holders are 5mm Aluminium tube from the hobby store. Might need a drop of glue to hold in place. The axels used are 3/16" threaded bar which fits perfectly in the Al tube. Geared Motor used was from https://www.jaycar.com.au/70rpm-12vdc-reversible-gearhead-motor/p/YG2732 No doubt cheaper alternatives exist. You need to drill a hole in the motor attachment and one of the claws and bend some piano wire up as a push rod. I was making this up on the fly so didn't really plan the hole placement...just a bit of trial and error. Hot glue some cheap solar lights around outside. May need to solder extensions on the lights to allow the claws to move freely, see video/photos what I did Quick video of mech and end result at https://youtu.be/ZyQaMih5vMc
