One of LUNA's core features is the ability to perform protocol analysis of USB 2.0 low-speed, full-speed, and high-speed. For most target devices, LUNA can endlessly stream the capture directly to a host PC over its own high-speed port. However, for high-bandwidth target devices that can't be streamed in real-time, LUNA has 8 MiB of memory on board to buffer captured data before sending it upstream. Read the full update.
Over the next while we will be updating the LUNA project to use “Amaranth HDL”, which is the new name whitequark and other maintainers have chosen for their project. Amaranth is the hardware description language used in LUNA. Read the full update.
LUNA is delayed. All of us at Great Scott Gadgets are sad to have to give this news, but the global chip shortage and supply chain chaos has impacted our LUNA manufacturing and delivery timeline more deeply than anticipated. Unfortunately, LUNA is now expected to start shipping December 2022 because the lead time for the ECP5 FPGA chip we use on LUNA doubled between July and September. There isn’t a suitable substitute component for the ECP5, so our timeline depends on Lattice’s production schedule for this chip. Please know that getting LUNA into your hands as soon as possible is our highest priority, and has been since before the Crowd Supply campaign was launched. Read the full update.
In our last update we asked you all for feedback about whether populating the optional Pmod host ports would be a welcome addition to LUNA, and whether they should be added to bare board LUNAs, encased LUNAs, or both. We got many comments through our Discord, direct messages, email, and GitHub. The feedback was overwhelmingly in favour of adding Pmod host ports to encased LUNAs only, so we are going ahead with that change! Read the full update.
It is almost the end of the LUNA Crowd Supply campaign! Thank you so much for coming on this journey with all of us at Great Scott Gadgets by backing LUNA, reading these updates, attending our AMA, joining our Discord server, and asking questions. These last few hours are your final chance to purchase a LUNA board, or a LUNA in a case, before prices go up after the campaign. This update also includes details about our enclosure!

Ten years ago this summer I quit my day job at a radio research lab and made Great Scott Gadgets (GSG) my full-time job. I dedicated myself and the company to our mission: to put open source tools into the hands of innovative people. Read on for the rest of the story and for a brief time line that shows how LUNA came to be. Read the full update.

Here's a peek at our current progress on the aluminum case for LUNA, and how we got here. Plus, a design contest for a custom etched case. Read the full update.
Every time USB hacking comes up, there's always someone who's convinced the conversation is about to veer into the deepest of dark magics. At GSG, we've always found USB to be much more inaccessible than it is complicated. USB feels like something every engineer, hacker, and maker would be able to have fun with – if only the tools weren't so expensive and limited! Finally, while teaching a class on USB, we decided to do something about it. The inspiration and sketches that followed became LUNA, a USB multi-tool designed to be ultra-cheap and way more capable than anything else out there. After nearly two years of development, we're thrilled to be launching this campaign. With your help, we'll put LUNA into the hands of innovative people everywhere! Read the full update.
