Aluminum Whisky Ice BAll Mold/Melter

Whisky drinking with fancy ice here we come!

Using a $7 ebay woodworking router bit and two chucks of 4" round bar aluminum.

Just need to figure out the right ice chunk sizes to use and a stand to hold the press together.












update: 2018/1/2

Printed a sleeve to hold the alum molds together.



Now I just need to figure out clear ice and some good starter ice tray molds to use before the pressing and drinking.

Halloween 2016 - Baby Dolls

To the thrift store for two slightly used dolls - can't beat 40 and 80 cents.

So sorry little gal but you need Red LED eyes!!



I never used servo's before - but found 5 sets of these cheep 28BYJ-48 Stepper Motor's for $12.68

I searched Thingiverse for a pulley created with openSCAD that had the stepper connection and quickly modified it as I don't need the V-groove (thing:913582). I screwed it directly to the gals head.


Looking good!

Next wire management - as I want the head to speed without twisting the wires. Searches on the webs came up empty with slip-rings that would fit my needs so - I designed my own thing:1824060 ;-)

I had issues getting power through the bearing so I popped off the dust cap and cleaned with wd-40 to flush out the grease.

   






Works great - well until the gal's stuffing gets wound out inside the bearing because it's missing the dust cap!

Next up is sound with this $9.99 MP3 Player with the help of this wikigit code and free Poltergeist MP3 we are good to go.

Halloween 2016 - Jumping Clowns

So I'm updating my 2015 Jumping Clown - CVS has restocked for the 2016!

So I'v added 2 more to my collection. They are a bit different and with the colors and with audio voice.

Anyways - I wasn't really happy with the setup of last year as I used a string to keep the clown from flying to the moon and after a while the spring would fail - not good.

So I've come up with a modified version that has a stop at the end of the cvpc. 

Here's the first test
 opps - need to glue the pipes.





It might be hard to see but the pipe is a bit too long and extents into the elbow so it can't get the lift that it needs to raise the clowns.



After cutting the pipe down - it's flush with the elbow.



Added painters tape for a tighter fit and grease - also note the hot melt glue used as a plug.



As I'm going to be running 3 clowns - I'm going to use a manifold to supply the air with all the valves in one location and running the hoses to the props.



Building the manifold only required a Lowes and two different Home Depot locations to find 3/4 x 1/4 bushings - it didn't help that I got a few 3/4 x 3/8 bushings the first time.

Here's two of the stands build from scrap wood.


I'm adding two of these cheep harbor freight HORN for when kids/adults get too close.












And Halloween is a go!
