Make your own MP3 player, with an FM transmitter built-in, using a box of Altoids. This site has the instructions to make your own MP3 player.

Limor's site itself is full of resources and has some cool HTML navigation.

Till's Palm Pages has it all for creating a tilt sensor for your Palm PDA. It has instructions to create your own Tilt Sensor, tilt enabled software and source code to incorporate tilt support in your software.

This is a serious hardware mod and so a little more than a evening project. In any case it is too cool.

I am a big fan of the Palm OS based PDAs and am always looking for something to do with my collection of Palm PDAs :)

Just bumped upon one very cool use. With Tom's Hardware and so many others writing about Home Theater PCs, we all want to have one. I built my own using Myth TV with everything needed including a nice black case to blend with my other components. The one thing missing was the LCD screen. Then I read about PalmOrb on Sourceforge. Here's a little excerpt from the site:

"PalmOrb is software that allows you to use your PalmOS device as a LCD status display for your computer! You can display system stats (such as: CPU load graphs, CPU temperatures, free disk space), news alerts, stock indexes, WinAmp graphs, etc."

"Koolio is a traveling autonomous refrigerator robot -- Picture a cross between R2D2 and a vending machine. It is designed for use on the 3rd floor of Benton Hall at the University of Florida . This floors houses the Machine Intelligence Lab (MIL) as well class rooms and professor’s offices. Around here professors are always working diligently in their office and sometimes can’t even find the time to get up and get a drink. Now they don’t have to worry. Here is the sequence of event."

It's been a long time since I have seen this thing on a mpg stream. Apparently someone has too much time on his hand and converted it to Flash a movie.
This "how to" can make you realise that your mummy was wrong after all, and she has showing us a wrong way of folding our T-Shirt.

I am posting a link for a general interest reference of the 2nd and 3rd generation iPod remote Control Protocol.
Let us see something interesting coming out from this reference. For example, a homemade iPod remote control.

Here's the link

I have always wanted to find a cost effective way to polish my pennies, but without the need to buy expensive chemicals and other marketed polishing products.
While searching online I found out that this could be done by using off the kitchen shelf products such as Taco Sauce, Tabasco™, or vinegar and salt you can successfully have a well polished penny (Woohoo!!).
To share my findings for those who are interested here's the link.

A couple weeks ago we had a link to MP3AR for hardware and software to build your own mp3 player. YAMPP (ironically stands for "Yet Another MP3 Player") is another site to download software and hardware schematics to build your own MP3 player.

We had such a positive response with our Free-As-In-Beer Mac disassembly instructions last time around, we decided to do it again: We've made six more FixIt Guides, perfect for those intrepid road-warriors who refuse to trust anyone else to work on their 'Book. Now there's nothing stopping you from trying that

This site here shows you how much fun you can have with putty and some canned air. Basically shoot the liquid from the canned air into a putty ball, as it expands into gas, the putty ball grows, then pops.
