Skype Freezing on Windows 7

For the last couple of months I've been having a problem with Skype freezing up for 1-3 seconds every time I'd click to another application and come back. After 2 months or so of hatred for Skype, I finally found a fix that appears to be working.Open Internet Explorer -> internet options -> security -> …

Progress – and moving forward

I've had these blades for like 4 weeks maybe (sometime the week of the 24th of Mar).  I built a slideboard like the next week.  I've used the slideboard a few times (mostly b/c of weather).  I've managed to get in a skate about 2x a week (mostly due to location).  I'm trying to find …

AVR programming on a Mac

I have done a lot of my work locally on WinXP running in Parallels.  I bought the book Make:AVR Programming which I cannot recommend more for anyone wanting to do AVR programming.  With that, I installed http://www.obdev.at/products/crosspack/index.html - and then his examples use make files to build and flash to the AVR.  I would like to see …

Laser tripwire

My son keeps asking me if we can build a laser tripwire.  The idea is that a laser hits the photoresistor and if anyone breaks the laser beam then an alarm will sound.  Sounds great and annoying.The circuit is very simple.  A photoresistor, a 10K resistor and a laser pointer.I used this link to provide …

IR Emitter and Detector

About 2 years ago I worked for a company that made hardware and went on a RadioShack buying spree.  I bought an IR Emitter and Detector, but didn't know anything about hooking them up.  Over the couple of weeks I've gotten back into wanting to do some cool stuff with electronics including sending some sort …
