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

I will start with the drivetrain. This is the H-Bridge I bought. Anyone have a tutorial for this one?
I'm back and working on the OmniBot hack.
I liked how B.O.B. bot has the lights that flash along face plate. It's a sequential blinking. Do you guys have any recommendations for lights, led, rgb or anything else so I can mimic it.
Thanks!
For the head rotation, I initially removed the tabs but the head did not rotate freely, it kept hitting the sides. So I shaved off the plastic using a belt sander. I also added foam to create friction.
Hey - that's exactly what i did. I used a dremel to cut the plastic around the head disc. I didn't cut it very smooth... yours looks better
You should use a standard servo for head rotation. Micro servo won't last very long. Trust this with my experience.
Thanks Dj!
rb550f, I already burned one out! :-)
I'm using the servos that came with the EZ-B Kit for the shoulder, elbow, and claw. The elbow and shoulder servos both make a lot of noise. Should I try replacing them or counter the weight some how?
Oh geez - i didn't notice it was a micro servo. I agree with @rb550f
The HDD servos are best to use for the arms and elbow. Are your servos HDD or HD from the kit? depends what version of the kit you have. Look at the servo label
@Dj, these are HD. What are the specs on the HDD?
The sticker is the same as the ones listed here (HDD): https://synthiam.com/Shop/AccessoriesDetails.aspx?productNumber=7
