LM3914 Led mouth.

Hello everyone,

Here's a video of my led mouth I made for my "blue Freak Machine".

This is the circuit I made for it:

 

In my case the leds are numbered as follow:

8 6 4 2 0 0 2 4 6 8

9 7 5 3 1 1 3 5 7 9

 

Edit: Oops i mixed up the 3914 and the 3915.. they both will work anyways..

Solar powered motors

Test with solar panels and motors!
3 solar panels give enough current to move a couple of these popular 3-6v motors, with 6 470uF capacitors as buffer.

I will test soon with an arduino nano and a driver:)

servos are not working

I have a spektrum dx5e transmitter and a ar610 reciever. I believe that they are paired because when I turn on the transmiter the recivers light turns on.
