Man,
I just though I'd have a play with my ez-b having not played with it for a while, but when I connected the battery, nothing happened. Removed the power and re attached it a few times when it decided to just go pop
Anyone any idea what happened? And whether its repairable? Really can't afford another one at the moment
Matt
Do you think replacing the blown component should make it work again? Anyone know what the details of the component was?
So gutted
Basically same thing happened to me last year with my EZ-B, I replaced the regulator and it works fine, however I didn't have a cap pop. That cap is 220uf 6.3v cap if that helps. The regulator i'm trying to find the info on now...
That'll teach me to trust the colour of wires without checking. It was indeed down to the adaptor I cut off the old omni battery having the colours backwards (see in the photo, red has to go to black and black goes to red)
Thank you, thank you, thank you for designing the board for fools like me
Matt
Use a pair of side cutters, little ones... and cut away the material from the old capicator. Also cut away the electrical leads so they don't short. You're EZ-B will look better without that capicator
It's funny, when I blew up an EZ-B before - it was from the Omnibot connector also! I was super surprised to find that negative is Inside and positive is Outside. Totally backward!
@dschulpius thanks, I'll drop support an email and see what happens. I may convert it to wifi if it is shot.
But without should be ok
i would check the 5 volt line going to your bluetooth to see if its good
Hevent had the time yet to reverse engineer it and draw the circuit up,i can tell you more about it
Since designing and making battery power circuits is mainly what i do at work
You will need to replace the Bluetooth module
