Picture of How 2.0: PB&J Mechanical Munchie Maker
Sure, you could just use a knife, but that would be so....retro. Techno-Guru Brian of technology makeover show My Home 2.0 introduces his sweetest invention ever: an assembly line machine for your favorite sandwich. Great for busy parents and tech-hungry kids. To see instructions, more great DIY projects, and their latest state-of-the-art home makeovers, visit: http://www.2pointhome.com.

A wise man once said, give a kid a peanut butter and jelly sandwich and she'll eat for a day...but give that kid a crazy, motorized, conveyor-belted contraption that makes peanut butter and jelly sandwiches and that day will be a lot more fun! (And yes, that wise man was me.)

Step 1: Self-analysis

Take a long hard look in the mirror and ask yourself, do I really need a giant machine to make one of the simplest sandwiches in the world?! If you're like me then the answer is a resounding YES!!!!!!!

Step 2: Get various 110v AC motors

Get yourself some used 110v AC motors at various speeds: 20rpm, 40rpm, 60 rpm, and 120rpm. (Sounds like a lot, but trust me you will want them in the end.) They all should have good gear ratios on them.

Very important: Make sure that you get motors that go in reverse as well!

(The reason for the AC motors and not DC is because AC is easier in the end, but hey, if you got a bunch-o-DC motors, go to town -- I'm not gonna
stop the creativity on your part.)

Step 3: Make conveyor belt

For the conveyor belt I used leather and sewed it together with my industrial machine, but you can use your grandma's sewing machine and break it....just tell her that you don't know what happened to it or how it got that way after you're finished with it. (This step is best done when she's not around!!!)

I also used four 7" paint rollers for the "wheels" and some 1/8" thick aluminum on the sides screwed to a piece of wood to hold them together. Attach one of the 20 or 40rpm motors to one of the outside edges. The whole conveyor belt system should be about 22" long.

that says "RUBE GOLDBURG" all over it
This project is around 60 hours to build and thats assuming you know what your doing. Because of time constraints I was not able to catalog the process. Every inch of it is custom fabricated with the exception of the motors. I have another project coming up that I cataloged the entire process and I believe it is better then this but thats totally subjective. It should be done in about a week or two. I'm glad you enjoyed my totally pointless invention.

Nice! Like The Muffinator said, with a little more work this instructable could be feature worthy.
Whoa! This is really cool!

You may want to use the Macro function - as some of your pictures are quite blurry. Also, you should either provide more photos that explain your text, or explain the steps better in the text.
For example, "Next I built a tower out of 3/4" square tubular steel and welded it together like this." Does not explain how you welded the tower, nor does it reference a picture that shows how you welded the tower (not the actual welding, but the structure).

This is a great idea - it seems like you put a lot of effort into it, and I'd really like to help make this instructable feature-able.
