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.

FPV RC Rover Using Smartphones

I initially built a servo driven RC rover for my son to play with and because i found it to be something i have to try for myself. Who would guess the rover just been driven by two normal 9g servos. Thanks to rctestflight.
I just take it a little bit further by testing it for a ground FPV platform. Inspired by a friend who uses two smartphones as an FPV gear for his quadcopter, i dig out my old Galaxy Ace.

How To - Servo 360 Mod

I get a lot of question as to how i did the servo mod for my rc rover. That is involving modifying a normal 9g servo to be able to turn freely on both direction.
I got the tips from a youtube channel rctestflight which happens to be the same person i got the idea to build the rc rover. The build is really cool (you can ask my son) and the modification needed is simple. Anyone with a spare servo and couple of old broken one could easily make it.

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.

My Surmount Face Lift

It has been long since i first set sail with this model sailboat Surmount from HobbyKing. Although i got it as a second hand owner from my fellow rcer who got himself a new and bigger boat. It is fast becoming my favorite model for weekends. Since i got it, i have change the rigging, change the rudder servo and change the jib sail. But a friend of mine who recently bought himself a Surmount has shown me what have he done to his boat, which catch my attention to do something more to my boat.
