The Dangers of LED Constant-Current Boost Drivers - Hazardous to your Arduino!

Does this picture look familiar to anyone?   In particular, the raised bump of melted plastic on what used to be the voltage regulator for the Mega2650?  I hope not too many! 

Trinity robot chassis upgrade!!!

Dear: LMR

Just to let you know I have recently built a new chassis for my trinity firefighting robot. The purpose of me building a new chassis was that the old chassis was too diffucult to use and debug. FIrst of all it was a self ballancer robot which made it diffucult to control. Second of all it was so tiny it was diffucult to debug the wiring. Any opinions on the new chassis? Thank you.

From: Noah

PS: I used the same electronics from the old robot to the new robot including motors. Enjoy!!!
