BrewPi Spark 3 update (almost ready!)
Just a quick update on the BrewPi Spark 3. We’re getting really close to release now.
Injection molded casing
I hoped we could release tomorrow, but we were not 100% happy with the new enclosure after the first test run of the mold. Let me illustrate with some photos.
As you can see, an edge is visible around the display, an edge we didn’t design on purpose. We thought the edge was caused by the ridge that holds the display in place on the inside. When the plastic cools it shrinks, and because of this features on the inside can cause a small deformation on the outside if they are too thick. So we did the following modification:
The result however, was disappointing. It had not solved our problem, as you can see below.
We figured it must be some combination of the very fine grained surface finish and the curvature of the front panel. Next plan: polish this area of the mold to a high gloss finish.
Finally, this redesign worked. And it looks nice combined with the glass panel of the display itself. The 2-tone casing gives it some extra character too. Our injection molding partner will take the mold apart one final time to polish again and get it really shiny and smooth.
We also tested the Spark V3 for CE approval, this means:
- Our products generates no radio waves that can interfere with other products
- Our product is immune to emissions from other products (or your amateur radio enthusiast next door)
- It can withstand electrostatic discharges of several kiloVolts on exposed pins (ESD)
Tests passed ✔
So when you buy one?
Looks like they’ll be ready to ship after a week, so Monday, July 10. Sorry for the delay!
Not yet, but it looks like this week is the week!
Just got the 4th test batch of enclosures. Quick photo:
I will receive another test batch of enclosures (nr 5!) tomorrow. These should be good according to the supplier, if they indeed are, we can ramp up production quickly and start selling on Monday. I’m not happy with the delays either, but after all the time I put into this new hardware release, I want it to look perfect too.
I check almost daily for the release of v3. As some others, I am ready to go with all of the other parts for my fermentation chamber. I’ve searched and have not found anything like the spark. I feel Ike an impatient child waiting for the release.
I hope you are having enough made…can’t wait.
Good news, enclosures are good now!
Release date: Monday
Will this include the release of the new software version?
