@jstarne1, Thanks! It's a big work in progress. Once I get him to a certain point, I'll showcase it.

He's an Omnibot. I've got his clock/display and tape player working. I wanted to keep as many of the original functions as possible.

The EZ-B is installed where the old battery would have been. He has an on/off key switch (top right), and tiny warp core looking thing (it's a re-purposed raver toy).

I've installed the usb/camera dongle in an old laser tag sensor (velcro'd to the back of the laptop that runs ARC).

I used an original Ghostbusters "trap" toy as a backpack. It houses his hbridge and mp3 trigger.

I'm still working on his camera, mp3 trigger, and distance sensors.

Anybody out there know a simple way to power the Omnibot's original circuits with the EZ-B? For instance, would I be able to power him the same way I power an led, with a pwm?

You guys have been phenomenal btw!

What original circuits are you trying to power. Personally I would replace lights with LEDs and yes a digital port can power those directly.

I think I'm asking the question the wrong way. scratches head and thinks

I'd like to power the Omnibot's original/factory board, but using the EZ-B. That way he could play tapes. I thought about using a pwm, run the wires to his barrel jack, but leave out the +5... The same way I wired/powered his LEDs.

I'm just not too keen on experimenting with the little guy for fear of popping his original board. I'm hoping someone can tell me if the pwm way would be safe to power his original/factory board. If not, can someone offer an alternative that doesn't require the addition of another battery pack.

The Omnibot was born to play tapes
