Project logs / Teardowns
I want to share pics of my electronics teardowns. They are not the most detailed or finest quality, but I hope you find them interesting.

Most, if not all of the pics are hosted on my Flickr account, but if you know a better way to host them, let me know. I chose the Flickr, because at my opinion it wasn't so PITA as most others I knew at the time. I've been thinking of hosting them myself (by turning my Seagate Dockstar to a server?), but I'm not sure about that yet.

I'd like to hear your opinions whether to include the images on the forum or just the links to them?

Project logs / I need help to fix an old PSU
I bought an really old (1988 or so) PSU from second hand store. It is a 13,X VDC 5A PSU for Mobira "mobile" telephone :D When I plugged it in, it only gives one volt or so, and screams with high freq. I don't even know what component it is that is screaming, some short circuit protection I guess. (My dad has similar PSU and it keeps the same noise when shoted, but it works...)

General discussion / New tools
Hi! I thought that it would be nice to see what kind of equipment people use. I got today a new soldering station and el-cheapo-dremel. If you like, please post some images/comments of your tools :)

Project logs / MP3 player earmuffs
This is one of the first projects I have ever made. I have partially broken radio earmuffs (radio doesn't work well) and partially broken mp3 player (vol-up smd-button missing). One day I decided to join them. I don't have pictures yet and it maybe won't be pretty, but it it works, I'm happy.

I don't have any idea what buttons I should use to control the player. I looked through Digikey catalog and it didn't help. There are so many choices and I only need few normally open, somewhat waterproof buttons which are easy to mount on curved plastic. I looked at Dealextreme too, but they seem to have only clicky flashlight switches.

If someone knows what to seek for or where, it helps a lot.

USB Infrared Toy / Is 3.3V UART possible with IR Toy?
Hi! I need a 3.3V serial port, and IR Toy has one. I tried to look from PIC manual and everywhere, but found nothing interesting. Then I measured 5.0V between TX and GND. Is there a software way to use 3.3V logic level or should I try something else?
