Hi Guys,
When rummaging in the attic I found my old Omnibot with the remote and the original battery pack
The battery is dead but I popped in two double A's and the digital clock still works. I was too young to really understand what I had was more than just a toy (I was 5 when I got it).
Anyway, I want to work on a project with my daughter. She's 7 but she's taken a real liking to electronics after I got her a snap electronics kit. Can anyone suggest a good project and what basic hardware I should purchases (servos, sensors, etc.) to get started.
Thanks, Ali

Anything else I need to get started on my Omnibot while my wallet is still out

It's knowing where to stop!
I had a budget for Melvin, I used that budget 5 times over already!
Spiral wrap is handy to have to keep wires neat, or tape...

What does the front of Melvin look like?
Found him!
For cutting the excess plastic around the head/eyes I will use a dremel but what do you suggest about smoothing out the plastic -- 200 grit sand paper?
The dome is scratched and beaten. I remember as a kid the painters dropped white paint on it too
Any thoughts about smoothing that out?
Thanks, Ali
There are reports (however I've personally never managed it) that using toothpaste can remove scratches from the dome. Or sanding with 2500 grit wet & dry.
I haven't yet smoothed any of Melvin's plastic. The dremel tends to melt it anyway so it leaves a pretty neat edge. But yes, sand it, 200 moving up to 800 or 1000 should do it depending on how you finish it (paint?). You could go mad and go up to 2500 grit, polishing compound etc. but it's probably not needed if you paint it, in fact you want a slightly rough surface anyway for paint.
