Sunsky has good prices on LEDs. In particular, they carry ropes with 60 and 120 LEDs/m. They've also got an LED controller for under $3.
swappable joysticks on a small Tx. I've been wanting to fiddle with a tank-like controller for an arduino ground unit, but keep getting stuck on the asymmetric sticks. I keep hoping to find a supplier of 9x sticks!
Banggood has some stranded 32 gauge wire in short lengths for $1, including shipping.
DSM2 compatible Rx that has a UART and looks pretty nice for hooking up to projects with a real CPU. Connection is 9600/8N1, and provides stick positions at 50 Hz with a string like this:
where each value is an octet between 100-200. More details at the link.
There's a PPM port too!
nice idea for homemade nanoquad motor mounting. And check out the handmade MultiWii FC!
Servo Magazine looks interesting and is recommend by Chris.
