Hi everyone. My issue is my chip not supplying the amps I require.
I'm trying to make two 6w bulbs and a single 30w LED strip all blink/flash randomly (completely randomly, but I'll need to adjust the frequency of the change) independently, in the same style as a broken fluorescent tube that can't quite start.
This is the kind of effect I'm trying to achieve:

Using this circuit:

My issue is the chip (4026 counter and display driver) only supplies 100mA to each of the 8 channel, where as I need 2x 500mA and 1x 2A channel, all blinking independently. Perhaps there is a better way of doing what I am trying to achieve. Also, this is all held within a small wooden box unit (it's an art installation piece) so I'm worried about the size and heat dissipation of using multiple transformers, if that's what I should use.
Here are the diagrams for the circuit in which I need to raise the amps on 3 of the channels:
Here is a guy that's done it, but I don't understand the circuitry he's used (description under photo, scroll left/right for other photos)

Thanks for all your help!
