Our friend Bill Beaty from amasci.com has come up with a way to Melt a Beer Bottle in a Microwave!

I don’t know about you but sometimes you just need to take a note or a quick sketch. Rite in the Rain was always done it for me. Just add a pencil or a write everywhere pen.

There are a bunch of sizes and types from spiral bound to stapled. 8.5 by 11 down to the 3 by 5 ones you can slip into a pocket. Where else can you find tactical copy paper in either green or desert tan?

Added bonus: Need some quad ruled paper, isometric graphpaper or maybe just a sheet of Herbicide Application Record after all the stores are closed? No worries. Just fire up your printer and head over to their free forms page.

This is definitely not going be UL listed but if you need a welder on the cheap this is one way to go.

The “Tiny Tim” Welder

Looks like the University of Alaska Fairbanks has grouped the engineering and culinary arts programs together.

“How does an electrical engineer cook a hot dog? 1.5 A for 60 seconds!

Taken at the E-Week open house put on by the engineering departments at the University of Alaska Fairbanks.”

This Speaker Power Detector might be a project that you want to add to your existing stereo system. The author is working on a revision so it may be something to do in the near future if you don’t want to implement the prototype design.

“The circuit revolves around the LM339, a low-power comparator designed to be easy to operate from a single (positive) power supply. A comparator compares two voltages and outputs a high, positive voltage if the first input (”non-inverting,” marked with a +) is higher or a zero or negative voltage if the second input (”inverting,” marked with a -) is higher. The circuit design then becomes pretty clear — just some connecting parts to hook the speaker wires up to the LM339 and see whether there’s a signal on them larger than some preset threshold.”

How to make your own scratchpad out of nothing but a pizza box and an optical mouse. I’m sure everyone has a spare optical mouse–and if you’re anything like me–an abundance of pizza boxes lying around. Check out a video of it in action.
I love to see these sorts of ultra low budget hacks. Keep up the good work out there.

P.S Merry Christmas!

Merry Christmas from everyone here at Hacked Gadgets, keeping the hacking tradition alive the video today is three roomba robots performing Christmas carols.

“Make your Roomba a musical instrument!

RoombaMidi2 is a small Mac OS X program that makes your Roomba appear as a MIDI interface to MIDI sequencer programs like Ableton Live, Apple Logic, and so on. RoombaMidi2 is an update of the original Java-based RoombaMidi.

The CoreMIDI-to-Java APIs provided by Apple look to be getting deprecated (as are all Apple-specific Java APIs). To get around any problems, the updated RoombaMidi2 is written in Objective-C for the GUI and C for the “roombalib” Roomba control API.”
