New Hardware Developments

Hey Backers!

You’ve seen what we’ve been up to on the software side of things, but how about the hardware? In the video below, Rylan goes into detail about what changes he’s been making to the Peachy’s design and Scott tells us about the circuit he’s been working on!

Here are some images of the new galvanometer design:
We've swapped the position of the coil and magnets allowing for a far lighter mirror.
The increased efficiency gives us far higher mirror deflection and responsiveness.
Adding a small c-shaped core to the 2 magnets will cause the magnetic lines of force to be focused directly through the coil.
Here are some images of the new printer body. It features slotted side walls allowing for precise adjustment of the mirror assemblies. The laser and mirrors are also mounted in a new position allowing the beam to hit the mirrors at a more direct angle.
We've added tabs to the mirror assembly that fit with slots in the housing to allow for accurate adjustment and alignment to the laser beam.
Rylan testing out the alignment procedure.
Here you can see the lasers lens in a reflection on the 2nd mirror. The alignment was successful!
Looking directly into the beam... we don't recommend doing this with your camera, and certainly never with your eyes!
The slotted design works great but doesn't look so good... Don't worry, we'll be covering it up with the logo!
Stay tuned - There’s more to come!
