I know exactly what you mean. I need to have a good play with the timings and may make the script a little more complex as I like a double blink quickly but when it's 3 or 4 in quick succession it is a little like he has a nervous tick. A script to check the last couple of pauses and if they were both short to do a longer one would probably make it look much better.

Blinking eyes video is very funny

@dschulpius I must have missed your question.

The head is from a Brian the Brain toy. I was unaware of it until Tony from Conceptioneering emailed me offering it to me after I mentioned about adding the back part of a brain in after fitting the Larson scanner and leaving the top of the helmet off. And rather than use just the back half of it, since it fits so well, the front was used rather than the back.

After weeks, if not months of avoiding them the arms will be tackled next week. But for the last time. If I'm not satisfied with the movement and the look of the arms this time then it'll be time to put another idea in place.

I've been working on an arm design but the problem is each arm will need at least 6 servos, if not more. If that happens it will be time to rock two EZ-Bs in there. So much for the budget project, I guess he has evolved

On another note, the blink script was totally re-written. The timings just weren't good enough the original way, I wanted to keep the occasional double blink but avoid triple (or more) blinks and have them spaced apart more. For such a simple action the script is rather long but it gives a much more realistic feel to the action. I haven't recorded it yet though, I'm still waiting on the eye movement to be sorted (i.e. give better control over eye position).

But at least now I have 10 days off work to concentrate on this, hopefully the WiFi module and Serial LCD Display turn up too, I'm itching to get playing with the LCD.

Oh, and still no camera position has been found other than to replace the mouth piece and fit it there.

I forgot to post the script...

# Eye blink pattern script

# Version 1.1
# Date: 2013-03-28
# Author: Rich

# Random blink patterns with random close time between 200 and 250 ms
# 1 in 100 chance of double blink with 20 blink wait and 1 in 1000

$doubleblink = 0
$tripleblink = 0

:loop
SleepRandom(3000, 5000)
Goto(start)
Goto(loop)

:start
IF (GetRandom(0,100) = 1 and $doubleblink = 0)
  Goto(blink)
  Sleep(600)
  Goto(blink)
  $doubleblink = 20
ELSEIF (GetRandom(0,1000) = 2 and $tripleblink = 0)
  Goto(blink)
  Sleep(600)
  Goto(blink)
  Sleep(600)
  Goto(blink)
  $tripleblink = 100
ELSE 
  Goto(blink)
  IF ($doubleblink > 0)
    $doubleblink = $doubleblink - 1
  ENDIF 
  IF ($tripleblink > 0)
    $tripleblink = $tripleblink - 1
  ENDIF 
ENDIF 
Return()

:blink
Set(D9,on)
SleepRandom(200,250)
Set(D9,off)
Return()

I think I can use this code for an idea on my project. Thanks!

Thanks for the Brian the Brain vid. He's kinda cool but I could see how he would start to wear on my nerves. I think your doing him a kindness by giving him a real brain (EZB).

I see brian the brain is under $30 on ebay including shipping
