VariGage moving along nicely

The ugly prototype of the Varigage Circuitry.

Well, things are proceeding, slowly but well. I’ve been busy with Christmas and general work and relaxing but it’s time to carry on with the device.

This prototype currently has the following features:

  • An Arduino Mega (will be replaced with a PIC)
  • HD44780 display module, may replace it with a nice flat transflective LCD
  • an ugly keypad
  • Input for quadrature from linear scale
  • Output to DC motor
  • Switching 12v to 5v supply
  • rs485 transciever for communication to the anvil

All of the parts are made but not entirely finished. Going to finish them soon. I was able to assemble them and the actuation is smooth as silk.

Anyways, gonna try to finish the mechanical soon so I can have the ungly prototype up and running. Hopefully I’ll be able to get a finished version ready for the oil show.

Enough fucking around… The VariGage

Well, After some time thinking about it, it’s time to take things into my own hands and design what I want, the way I want it. Since it’s shortly after my 34th birthday I’ve realized that time is getting short and I have to forge ahead.

Hence, the VariGage. I’ll change the name later but it suits it just fine for now.

The prototype VariGage. Not much to it right now but the implications of a miniaturized version are great.

This device will allow for a multitude of gaging options with full communication between the anvils and expansibility. Gagemaker makes something quite similar however, mine differs in a number of ways in both design and use.

  • Affordability, the average machinist should be able to afford a unit to fit in their repetoire. While it’ll be a very expensive tool, it’d be nowhere near the 12,000 bucks or so of the GageMaker device.
  • Anvil communication. The device will communicate with the anvils allowing for future use of anvils that weren’t available upon first creation of the device. also this allows for cheaper calibration of anvils rather than the device itself.
  • The device is motorized. It will position itself to the desired location and hunt when the user is pressing and calibrating a gage on the device. The final version will involve a clutch to allow rapid hand positioning
  • Light weight with modular display design.

These are a few of the differences. The market is completely different from what GageMaker sells. I’m not even completely sure it’s sell able but I simply have to build it. I have a few other ideas and designs I have to get done but this is the first in the line and I think it’ll be very interesting when done. Heck, it’ll be nice to have if I go to another shop even, who knows. 🙂
