Using an Oscilloscope
Ever wonder what an Oscilloscope is? Or how to use one? Here’s a good guide on getting starting “An oscilloscope is easily the most useful instrument available for testing circuits because it allows you to see the signals at different points in the circuit. The best way of investigating an electronic system is to monitor signals at the input and output of each system block, checking that each block is operating as expected and is correctly linked to the next. With a little practice, you will be able to find and correct faults quickly and accurately.” Link.
Chris writes “Remote controls are a consumption product. They fall in the floor, the get coffee spilled over them, the get stepped on (maybe not..) – and they wear out. In this how-to we will show you how to revive your remote by swapping the buttons around. Easier then you think actually.” 
“Getting music to your Symbian phone is not as easy as it should be… If you are using a Nokia phone you may be able to use the Nokia Music Manager (which is part of PC Suite). This How-To shows you how Mass Storage Synchronizer can be used to copy music from iTunes to a memory card (which you can then put in your phone). This does not syncronize iTunes with the phone, it copies music from the PC (iTunes library) to a memory card in a USB memory card reader. ” Thanks Ewan! 
Here’s one of many resources for finding DOS games. If you have an old PC laying around, or looking to do something with one, these old games could make a great little gamer machine and will bring back a lot of memories.[
Excellent DIY iPod dock for tinkering on panocamera “I needed a quick way to test signal interactions with a microcontroller and an iPod, so for about $50 and an afternoon of soldering, I threw together an iPod dock/breakout box. Ingredients include a small breadboard, and a $15 cheapie usb charger cable, which when stripped of its plastic housing luckily has all 30 dock connector pins ready to solder.” 
Using an Xbox (1st generation) headset and a PSP headphone remote you can make your own headset for SOCOM PSP. You can likely use just about any type of headset, like the ones that come with cell phones too. 
Here’s part 2 of Fabienne Serriere’s great rotary phone to cell phone project “This week we bring you Part 2 of The Magic Phone How-To: The Circuit. The Magic Phone is a project where both a DECT compatible wireless home phone and a GSM cellphone are placed inside an old rotary phone. In Part 1 of the How-To, we showed you how to reverse engineer the matrix on a phone circuit.”
