Worm gear. Another functional print.

The worm gear on my office window blind mechanism broke.  I couldn't source the part for my specific model of blind, so I decided to model the part on fusion 360 and 3d print it.  It was definitely the hardest thing I've modeled yet.

Functional Prints

Here are a few functional 3d prints that I've designed on fusion360 and printed on my Ender 5.

The roller on my Neeto D7 vacuum got worn out an flattened on one side causing the brushes to scrape the floor.  The black part is the original and the white one is printed.

These are table leg extensions for my daughter's home study setup.

This one's abattery tie down for my Mini  Cooper.  

お弁当 (Obento) Japanese Lunch Box

I've started really getting into packing bento lunch boxes for my one year old daughter.  I'm not quite as advanced as some of these people, Kyaraben Images, but I think it's a good start!

Joule Thief

Today I get an email from my sister asking if I have an LED that can be powered by only 1volt. I've seen LEDs that work at 1.5volts but they aren't very bright to begin with so they probably wont be visible at 1volt.

Immediately I thought, hey a Joule Thief might work. I've been hearing about this circuit often on Hackaday and Make but never attempted to make it.

I dug a broken xbox motherboard and pulled off the torroid and I had a bunch of transistors leftover from my senior design project last year. Wired it up and powered it by 1 AA that my wireless mouse tells me is dead...

My meter shows 1.132 volts, yet it lights up the blue LED strong!

edit:

Still going strong at 0.947volts

Still blinding at 0.786volts
