LED Navigation Light with ATtiny45/85

Since a friend introduce me to arduino, i has been my dream to build myself a navigation lights customize to my liking.
He who played with arduino longer than me have come out with an on board navigation lights complete with strobe lights, beacon and even capabilities to switch your lights on and off using your remote control.
I think i am far from that, but i have build myself a simple navigation lights with strobe and beacon and i'm using ATtiny45 for its small size.

DIY 5v Regulator from old ESC

Hi guys. Just wanna share my latest discoveries. It is actually common thing within electronics gurus out there, but i am a newbie in this so this is something i am really excited with.
As for us who has been long involved with RC hobby, i believe we have quite a collection of burned out ESCs laying around somewhere in our home.
Now we can use it to power something else.

Simple DIY 5V BEC

I'm looking for a way to power my servo tester with my LiPo without using an ESC which i used to do. I don't have a BEC laying around, and i'm too cheap to buy one just to power a servo tester. Then i remember a friend of mine building his own BEC from a minimal amount of component to power his sailboat with a LiPo battery.
I start looking for parts in my workshop to make myself a DIY BEC and lucky me i have some laying around in my electronics box. A couple of hours later after some datasheet reading, schematic figuring, component placing and soldering, i got myself one simple homemade BEC.
