November 2025 Opulo Update

Hey everyone, happy November! Here's what we've been doing at Opulo this past month:

Lead Times

We're still actively looking for more assembly techs to join the team! If you're in the Pittsburgh area and interested, please don't hesitate to apply!

As always, the official lead time on each product's product page is the most accurate metric for when you'll see your hardware ship! There's a good chance we ship early, internally it's about a 2-3 week lead time, but we keep it where it is to ensure we're able to stick to our estimate.

Wide Feeders

Tweaks to the 16mm and 24mm feeder CAD have been made, and DVT PCBs have arrived at Opulo HQ! We're in the process of building up a small batch of units for our Beta program. The most recent PCB revision has greatly simplified power electronics, that are also quite a bit more efficient.

The very first DVT unit is on our production line, being used to make PCBAs that go into Lumens! As we've gone through the development process, we constantly swap out the latest version to our line so we're getting immediate feedback on how it operates.

We're shipping feeders to Beta users starting tomorrow, so hopefully very soon we'll have some feedback from others that we can incorporate back into the design.

So far, it's been really wonderful having these in operation. Loading tape, especially with this wider tape, is much quicker and easier to do. Not only allowing the film to be pulled taut when disengaging the gears, but also having the whole film peeling mechanism on top makes the whole process of loading much smoother.

If you're interested in joining the Beta for 16mm or 24mm feeders, please fill out this form to join the list.

Viagrid

I've finally posted a video about the Viagrid system, and how to use it for extremely rapid prototyping. Since posting, we've had a ton of folks in the Discord sharing some awesome ideas. We're working on a new layout that leans heavily on the work of MatinatorX on Discord, and should make layout much easier.

This layout incorporates a lot more vias, a slightly different pattern, and mounting holes (which I found my original design to be sorely lacking). There's also a number of calibration features along the outer edge that makes aligning with both a laser and a backlit UV curing option much easier.

You can check out the Github repo for Viagrid here. We're also thinking about changing the name, and folks in the YouTube comments far and away prefer "Biscuit Board" (a play on the solderless breadboard). What do you think? Let us know at support.opulo.io!
