Picture of STEAMPUNK STEAM GAUGE, POWERED BY ARDUINO
This was created to be some eye-candy for my kitchen. I wanted something unique for a special blank space on my wall, and adding movement, blinky lights and interesting mechanical “guts” made it even better.
Ultimately, this project ended up requiring the following range of skills:
1. Basic mechanical skills
2. Light metalworking and fabrication
3. Graphic design – for the new dial face
4. Circuit design
5. Arduino programming
6. Woodworking- for mockups and decoration
7. Drywall and 120V wiring – for mounting and permanent power supply

Step 2: IN THE BEGINNING: A FIRST LOOK INSIDE

This project started with a beat-up Ashcroft 10" pressure gauge bought cheap on ebay. The glass dial cover was cracked and the valve was frozen, but that didn't matter. The main priority was size, because ideally I would want to add stuff inside it. If the mechanical guts of the instrument were "interesting" enough, then I would also want to make those visible as well.


Fortunately, the three screws holding the brass outer ring were not frozen or stripped. The pointer came off with just a little persuasion, as it was simply press-fit onto the shaft. The faceplate was also held in with three screws, all of which came out as well. The insides had the standard "C" shaped Bourdon tube, which flexes open under pressure. The mechanism was in good shape overall, but it would need some cleaning up and polishing. So far so good....

Step 3: THE BASIC MECHANISM

Great job. I like the movements you've chosen. LEDs add just enough "flair". I really like the Steam Punk look. Thanks for posting.

Wonderful work, and awesome that you were able to make the mechanical linkages work as well!
