More Blue Smoke

A project log for Pico-Kubik quadruped robot

The tinniest Arduino quadruped robot.

Today is a sad day for this project.

I decided to use a new battery that I bought specially for this robot, instead of using battery packs from my Walkera RC helicopter. Taught with previous mistakes, I have a socket for the battery that only lets you insert the plug the correct way. Being assured by this, I didn't really look carefully when I connected the battery... Alerted by the hissing and smoke from the power switch, I immediately disconnected it but... too late.

What happened? Look at this:

See? Battery packs from different manufacturers have the plugs in reverse... I suppose that increases their sales.

Unfortunately, this time not only the power switch is fried -- also the VoCore. The Arduino Pro Mini and the camera module seem to be fine, though.

This project log should be called "No more blue smoke".

Because you let it out. All of it.

Well, I do have another VoCore, and a spare power switch, so there is some still left. Hopefully it will stay in there a little while longer.

Noooooo :( I've had some similar experiences once with a power connector soldered backwards on a controller board for my 3D printer... One thought - rectifiers everywhere would be awesome. No color coded cables anymore.

At least the LiPo didn't explode...
