Parts Sourcing / 3D Printed Crow part replicas
« on: April 21, 2018, 02:20:35 PM »
Hi folks. Just wanted to let you know about a little project of mine that I'm working on to design 3D printable replica parts for the bots. Right now I'm in the middle of working on the parts for Crow, but will move on to Tom once I'm done. I'm posting the resulting STL files for anyone to use for free if they're having problems obtaining parts or need to make a bot on the cheap for some reason. (I do since I'm always working on making reversions of my automated versions of the bots, for example).

So, anyway, I'm posting the files up for free on Thingiverse as I go, so please feel free to take a look, use them, or provide any feedback on improvements needed.

A bot for every pot.

Tom Servo / MechaServo

While I'm building MechaCrow, I thought I'd share the details around the MechaServo build I did last year.

First, the MechaServo BOM:
  • 1 Standard Tom Servo kit or full set of standard Tom Servo parts.
  • 1 3 amp speaker
  • 1 Ardino UNO (other flavors may work)
  • 1 High torque micro servo (I use MG92B servos)
  • 1 Small stepper motor (could be swapped with a servo motor)
  • 1 Stepper motor driver
  • 1 Adafruit 16Mb WAV FX soundboard
  • 1 2.5w amp
  • 1 Arduino protoboard
  • 1 9v battery
  • 6 AA batteries
  • 4 Serial or Analog-Serial buttons and/or 1 RF receiver/transmitter trigger
  • Misc wires and resistors/capacitors depending on how you design the circuit and triggers.

This build can play audio of Tom Servo's voice recorded from video and converted to WAV file format. The Arduino, paired with the motors, allows you to also swivel the head and move the jaw in time with the audio of Tom's voice at the press of a button or any other assorted trigger. Since it's battery driven, it's portable and essentially replaces the puppeteer's hand with electronics.

Most of the steps in construction follow along with any other Servo build, except at certain steps where we shorten the control pipe, install some custom designed 3d printed parts, and install the electronics into the barrel and hover skirt. All of which I'll detail in subsequent posts if anyone is interested in trying their hand at this modified build.

It's not quite a "bot", but more of a poseable action figure... I made two versions, the larger of which was commissioned. Thought some of you might think it's neat, even if not entirely accurate to the original.

Here's a pic of Tom at MoPop (Museum of Pop Culture in Seattle) during a local maker faire with some familiar plunger-armed pepper pots.
