It took a long time, but now a new bechele software is available with the following new features:

  • No more Limit to support a maximum number of Servos (16 before) – now 1024
  • The software became much quicker while loading and for installation
  • Consolidated binaries. No more different programs for different hardware
  • Code base now hosted on github as a open repository
  • New Interface for, the teaching program for your servos
  • Possibility to copy servo movements to other servos with lots of helpful options
  • Possibility to add servo movements data by entering vectors
  • Disk image of Armbian Bookworm for OrangePi-PC available
  • Disk image of Raspbian Bookworm for RaspberryPi 1b available
  • Disk image of Raspbian Bookworm for RaspberryPi 3b available

    Hi there,

    So first off: amazing work, and thanks for sharing. So I haven’t dug into the software yet but I know I personally love to talk about my projects with others but if you don’t just let me know and I’ll see if I can find my answers by taking a peek.

    I’m looking to adapt your eye and brow control into a sock puppet I’m working on. I want to control the guy “live” and semi-manually, so my current plan is modify your “mouth and eyebrow mechanics” model so I can control the mouth like a normal sock puppet but have the eyes controlled electronically. I really only need the eyes to look left/right and the eyelids to open/close. How hard would it be (if possible at all) to have pots, bend sensors, or really any standard electronics input control the eyes? It would also be really cool to run short pre-programmed animations with a button press.

    Thanks in advance!

        Thanks for getting back to me. I randomly have a Raspi Pico laying around so I’ll give it a shot. I did see your eye mechanism designs but I ended up going with the one linked below as it seemed much easier to construct. I plan on modifying it so the eyelids actually look like real eyelids (like yours do) but for testing it’s good enough as is.

        I’m very new to Raspi’s, does the software take the form of a flashable Raspi dispo or is it software that needs to be installed on top of another dispo?

          Dear Blake, sorry for respondig so late, but somehow I have overseen your post. Unfortunately the pico is not the right device. You need a Raspberry Pi that may run the raspbian operating system. Currently only SD card images for Raspberry Pi 1b and 3b or OrangePi PC are available for easy installation (just install the sd card image onto the SD card using a disk imager software – for example Win32DiskImager). Some other mini computers that may install a linux based OS may work also, but then you need to install the software manually step by step with some effort and I expect some obstacles. See: If you are new I recommend one of the mentioned devices.
