Electronics anyone?


#1

Anyone into electronics here?

I just wired an Arduino and DMD display up for a science show today:

The kids will get some little remote controlled cars and race them around a track, using this to time the best lap and overall time.

Anyone else built anything with an arduino/esp/raspberry pi/etc… recently?

I’m building a small Arduino CNC machine with the step motors of old DVD drives.
At present, it is still a test setup for development of the control software.

Nice @Sealord ! I’ve never had success getting smooth operation of old CD drive motors. It could have been the brand I was using. Were you able to get accurate movements?

Laser CNC?

Got my hands on a Wild Thumper robot base kit the other day. Trying to hook a camera up to it and make it follow someone with a Pi + OpenCV
