Guitar Pedal Hack – How to Make a Guitar Pedal Power Supply!

Posted on February 3, 2010 by max

For guitar enthusiasts out there, you might want to check out this hack that involves making a power supply for your guitar pedal so you don’t have to keep using 9-volt batteries.

If you’re like me, you know how annoying it is to use up 9V batteries on your guitar effect pedals.  Its wasteful, and brand name 9V’s are almost $9 for a two-pack.  If you forget to turn off your pedals you’ve thrown away big bucks.  Its an extreme waste of money when you can build your own power supply for only about $25.

Rust DIY – How to Remove Rust by Making an Electrolytic Rust Removal System!

Posted on May 27, 2009 by max

As an immigrant who couldn’t speak English when I first came to America at the age of 9, I would keep myself busy by building things like Thermite, which is basically mixture of rust and aluminum.  Thermite is a great detonator for various bombs like TNT and whatnot, also used as emergency flashing guns.

Anyways, enough about me making thermite as a 9 year old, that was just plain, great chemistry fun, glad I didn’t lose an arm or leg during the process.  This can be great for removing rust

Here’s a nifty idea for future reading lamps, a dynamic hand-powered lamp that is completely driven by the energy generated by your hand, kinetic they call it.

Posted on February 5, 2009 by max

Removing rust can be a big headache but not if you use your brain a little and some electricity.

I used a 12V .5A power supply and attached the negative end to the pipe wrench and the positive end to a old piece of steel remesh. Both pipe wrench and remesh were put in a bucket of water that had some baking soda. After a few hours of bubbling I removed the pipe wrench and let it sit for a hour in a vinegar bath.

Thermaltake V1 CPU Cooler will not fit most PC Cases!

Posted on July 30, 2008 by max

Maybe it was just a picture, but the above pic does make it seem like the Thermaltake V1 CPU Cooler is too big to fit in most PC cases.

As you can see, the CPU cooler actually fits well inside a PC case while the cooling metal fins are designed right next to your power supply and vent fans for maximum cooling.
