Hello all,

Driller Shark has been upgraded, and here are some pictures for your visual enjoyment.

The original Driller shark base.

Now souped up with a higher board mount.  Right now it looks too high, but with the sensor in place it looks fine.

New board based off the Samm version 2.

I changed the motor drivers from the MC3387 to this new one.  The part number is BD6232.  Two reasons for the switch are:  The MC3387 is obsolete and the maxon motors would trigger a shutdown state in the driver.

New sensors.  Got these off ebay from Sure electronics.  They were cheap.  The downsides of them are it doesn't give a distance reading and it is slightly slower than I would like.

Mild steel bar added for weight because I had a problem with being too light in Toronto.

Drumroll please.......  DRILLER SHARK: AUGER!!!!
