  • Hi, would you be a be able to give me the schematics of the integrated circuit that Alberto made?

  • You'd have to email alberto, his website is intertlan

  • I'm courious what is the black mateial that you are using to house the electronis is it machined or cast. I'd love to see how you are fabricating them. I've noticed you used the same stuff in your other videos and it looks great.

  • Its a plastic called Delrin that is inexpensive and easy to drill and sand. I purchase it at mcmaster.

  • looks good Dan,

    You and Alberto make a great team. Keep up the good work.

    FYI the switch you show in the video is a roller switch. A reed switch is a magnetically actuated switch

  • Thanks for the clarification!
