calibrate failure

Hi Jason,

I followed your steps and after running node bot.js and doing calibrate gives following error

Your timely response is much appreciated.

This error:

RangeError: toString() radix argument must be between 2 and 36

Occurs when toString() is called on a number with an invalid radix. I've seen this before when two operations are trying to control process.stdin. What version of Johnny-Five is currently in node_modules?

@ubatra13 in node_modules/johnny-five/lib/board.js, find this line: process.stdin.emit( "data", 1 ); (it should be 304) and comment it out. Then run the calibration program and let me know what happens.

@rwaldron now I am getting different error while taping on control screen

@rwaldron also, when calibrating I get this

@rwaldron just to clarify because I guess I posted two issues here,

Issue 1. when calibrating for first time it went fine prints "13811111**** Repl Initialized" and then when trying out http://localhost:8011/control, I get the error I mentioned above.

/Users/ub/arduino/workspace/tapsterbot/src/bot.js:158
b = translationMatrix.elements[1][0],
^
TypeError: Cannot read property '0' of undefined

Issue 2. When I try calibrating second time, I got error as

1381111140745 Repl Initialized

/Users/ub/arduino/workspace/tapsterbot/src/bot.js:79
return ik.forward(servo1.last.degrees, servo2.last.degrees, servo3.last.degr
^
ReferenceError: servo1 is not defined

but Issue 2, I am not able to reproduce it now; so we can ignore it for now in case you know what it is?

I think for me, if issue 1 is resolved I am good to proceed.

[ubatra13]

@rwaldron please ignore, finally, it worked, I was doing calibrate step wrong, very thanks for your help.
