Sitting at the heart of the Ploopy Headphones preamplifier is a chip called “RP2040”. It’s the microcontroller, or MCU, recently made and released by the Raspberry Pi Foundation. It’s cheap, it’s available, and it punches way above its weight. This post will explain why we chose it for the Headphones preamp, as well as the… Continue reading RP2040: The Little Engine that Could

Using Spring Contact Principles with Chip-PCB Interfaces
This post answers a fairly simple question: how does a person electrically connect a very large number of chips to a very large number of PCBs in the shortest possible amount of time? Without the help of big fancy industrial equipment, that is. The question is simple, but the answer is far from it. I’ll… Continue reading Using Spring Contact Principles with Chip-PCB Interfaces
Unboxing Ploopies
If you get a kit from us, it is highly likely to arrive looking something like this: The box on the left is, indeed, a purpose-made box specifically chosen to ship our kits, and it’s wrapped in a tape that we’ve specifically chosen to inform the recipient that they’re about to receive a Ploopy. It’s… Continue reading Unboxing Ploopies

False positives on the filament sensor on your Prusa Mk3? Here’s how to fix it.
About two years ago, I started running into a problem with our print farm: the filament sensors on the printers began to fail. It was a very specific failure: the filament sensors started producing erroneous out-of-filament reports. That means that the printer would pause and beep, requesting new filament since it had run out. But… Continue reading False positives on the filament sensor on your Prusa Mk3? Here’s how to fix it.

“Ya’ll need a new name”
That’s an actual quote from someone who thought that the name “Ploopy” is shitty. Throughout the short history of our company, people have been asking my partner and I why we settled on that name. There’s not really much to it. We wanted a quirky name. I threw it out there as a wild suggestion,… Continue reading “Ya’ll need a new name”
A blog?
The way that my partner and I run Ploopy is sometimes a bit hard to explain. As a result, we usually don’t bother trying. It requires a lot of words. However, the questions keep piling up. Neither of us are answering them, so the pile keeps getting bigger. This blog will be a place of… Continue reading A blog?
