LUNA Delayed

Note: This is a crosspost of a Cynthion update on Crowd Supply: https://www.crowdsupply.com/great-scott-gadgets/luna/updates/luna-delayed

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...

Camera Trap Cookbook: Creating an ABR system

In this video, we show you how the BoomBox attaches to Bushnell TrophyCam’s PIR trigger to create an Automated Behavioural Response System (ABRS).

All Invited to the OpenTapeOut Open Source ASIC Design Conference This Weekend

The free and open source silicon community, both established and simply interested, is invited to a new event this weekend: the OpenTapeOut Conference 2021, hosted by Zero to ASIC course creator Matt Venn.

“We encourage all of you folks to join us at what we hope will be the start of a revolution! No matter who you are or where you are from, don’t care what you did, as long as you love ASICs [Application Specific Integrated Circuits] and electronics in general,” the event’s organisers explain. “We don’t expect you to have any serious pre-knowledge in ASIC design. Actually we’d love...

October Update Follow-up

Happy Halloween! As promised earlier this month, here is the follow-up to the October community update. Some of the topics I’ll touch upon will be covered in more detail in November.

How "Meet the PinePhone Pro" was made

As PINE64‘s flagship mainline GNU/Linux smartphone, the PinePhone Pro, was about to be announced, a trailer and some nice renderings showcasing the phone and its features had to be produced.

Alibaba’s T-Head Releases Four RISC-V Cores Under a Permissive Licence

Alibaba has released the source code for its XuanTie E902, E906, C906, and C910 RISC-V processor cores, promising to follow their release with additional development tools, software development kits, and customisations in the future.

Designed by Alibaba’s T-Head semiconductor arm, the XuanTie C906 was launched as a low-power in-order core for the Internet of Things, finding a commercial home in Allwinner’s D1 system-on-chip. The C910 is a higher performance out-of-order design, still built with the Internet of Things in mind, which has so far only been announced in a limited-production-run developer’s kit. The two E-family cores, meanwhile, are simpler designs for...

October Update: Introducing the PinePhone Pro

Welcome to what will likely be remembered as the most important community update of 2021. Today we’re introducing the PinePhone Pro and announcing that both PinePhone Pro and PineNote pre-orders are now open to developers.

Harald "LaF0rge" Welte: First steps towards an ITU-T V5.1 / V5.2 implementation

As some of you may know, I've been starting to collect "vintage" telecommunications equipment starting from analog modems to ISDN adapters, but also PBXs and even SDH equipment. The goal is to keep this equipment (and related software) alive for demonstration and practical exploration.

Some [incomplete] information can be found at https://osmocom.org/projects/retro-bbs/wiki/

Working with PBXs to simulate the PSTN (ISDN/POTS) network is fine to some extent, but it's of course not the real deal. You only get S0-buses and no actual Uk0 like actual ISDN lines of the late 80ies and 90ies. You have problems with modems not liking the PBX dialtone, etc.

Hence, I've always wanted to...
