Let’s face it, sometimes you need to take time out from engineering cutting-edge electric vehicles to over-engineer a beer fridge. And to tell you the truth, after seeing what [Matt Brown] managed to pull off we now have a gut-felt yearning for one of our own. He took a beer fridge and added a vanishing dispenser handle from a Tesla Model S.
You might be thinking that this an expensive part, and you’ve be more correct than you realize. It’s not even a stock part. This is a prototype that someone threw in the trash. [Matt] plucked it from oblivion and milled a spot for it in the door of the fridge. Your average [Joe] probably doesn’t know that the Model S comes with handles that pull themselves flush with the body of the vehicle.
[Matt] dug out insulation on the inside of the door until there was room to cut a hole for the handle. The clamped the assembly in place and used spray foam to re-insulate as well as glue it in place. An Arduino monitors the area below the tap. When you put your glass under the spout the handle extends. When you pull on it a solenoid drives the tap handle forward. This sounds pretty dry, but we think the demo after the break will have you lusting after one as well.

This color changing door handle was made using a very simple manufacturing process. [Barmak] already had experience working with polyester resins when making passive component filled drawer pulls (he included a couple of pictures at the end of his post). The same process was used here except that instead making it from one solid chunk of clear resin he decided to use alternating layers of dyed resin.
The build begins with a mold made out of MDF. This material has a very smooth surface finish which will help with the final look of the door handle. Threaded rod is inserted through carefully placed holes in the side of the mold — these will serve as the mounting hardware when complete. He then pours thin coats of resin to build up the complete handle.
An RGB LED strip is incorporated in the side of the handle that will go toward the door. It seems like the wires to control the device pass through a hollow spacer surrounding the threaded rod. He makes some mention of using a 555 timer to control the colors, but there’s not much more information than that. Still, the reflected light is a unique feature if you’ve got a place in your home that needs to be spiced up.
Once you’re done, you can use any leftover resin to make your own project boxes.
