(EDIT: clarification, the plan had been 96 ports total since at least 2015, since that's what I had in existing Cisco switching. The major scope creep over that time was deciding that 2x 48 port switches with a bigger FPGA would be a more power efficient, easier to build, and generally superior design to 4x 24 port)
All that's left hardware wise is to design the main logic board with the FPGA, processor, and SFPs, plus the mechanical and thermal design of the 1U chassis. I've been focusing on firmware due to the tariff situation and wasn't planning on spinning the production-ish hardware for quite a while.
I don't plan any further scope changes now that I've e.g. already put in the production line card PCB order and mostly finalized the fabric architecture. I'm just holding off on the final logic board design until I'm sure about, for example, whether I'll want external packet buffer SRAM like LATENTPINK had or if I'll be fine with the KU5P's internal memory resourecs.
As far as the probes go, yes the antikernel.net site is way out of date and I've been too busy to refresh it.
* The AKL-PT1 did a kickstarter and I shipped probes to backers, but I stopped selling them because the fixed tip/ground spacing was too awkward and made it difficult to use.
* The AKL-PT2 (first gen solder in probe) was for sale for a while but extremely fragile, only 4 GHz bandwidth, and also had fixed signal/ground spacing.
* A few in-between designs were total flops and never reached the point of shipping a single unit
* The AKL-PT5 (second gen solder in probe) is >16 GHz bandwidth and has a flexible resistor based solder-in tip and a much nicer form factor. R&D is done but I ran into supply chain problems with the specialized resistor it needs (9 month lead time, poor yield, etc). I think I've mostly worked around those issues and I have a PVT run of a hundred units in the pipeline now. Fingers crossed they'll be hitting Digikey in the next 6-12 months."},"story_title":{"matchLevel":"none","matchedWords":[],"value":"Open Hardware Ethernet Switch project, part 1"},"story_url":{"matchLevel":"none","matchedWords":[],"value":"https://serd.es/2025/05/08/Switch-project-pt1.html"}},"_tags":["comment","author_azonenberg","story_43934869"],"author":"azonenberg","children":[43971415,43971708,43972488],"comment_text":"The plan is 96 ports total for my own use, split across two 48-port 1U switches.
