| I just finished building a bicore head from your tutorial last weekend. worked great first try with no problems whatsoever! I used a 74AC240 with a modified servo and powered by 2 AAA batteries that have lasted for quite some time now! I've been using it all week and they haven't gone dead yet! Great tutorial!

| It works great and now, 2 months later, the batteries are just starting to show signs of becoming dead. I'd say they have lasted for at least 30 hrs. of spinning. Great tutorial! 27 May 2001 |
