Live and recent posts from across the Fediverse tagged #haifuraiya, aggregated by home.social.

  1. Found a potential issue with the Theseus Cores #polyphase channelizer. The volunteer already has a fix in mind, and it's not a deal-breaker for lab demonstrations.

    #Haifuraiya progress! This is an #opensource #satellite #communications design and will be prototyped on the #hamradio #microwave bands.

  2. The magic of seeing the people I support at @OpenResearchIns get great things done never gets old!

    Thank you to all our volunteers for another great week. Getting up on a Monday and being able to dive right in and help #opensource digital radio work is a privilege that I do not take for granted.

    Most of what we do is on the #hamradio bands and is of direct benefit. The proof is what's on the air, from #ribbit, #RFBitBanger, #neptune, to #Haifuraiya

    Next demo? #defcon32 at #RFVillage.

  3. Testbench passing for #polyphase channelizer for #Haifuraiya, an #opensource #HEO or #GEO communications #satellite design. Applicable to #hamradio, 5 GHz uplink and 10 GHz downlink. Shown is the transponder receiver filter.

    If you’d like to join this or any other @OpenResearchIns project, get in touch.

  4. Thank you to everyone helping with both #ribbit and #rfbitbanger, and with all the #fpga work for #neptune and #Haifuraiya

    We couldn't do it without you. Some great #opensource #hamradio work going on supported by @OpenResearchIns and #ARRL, #qsotoday, #RAPAC, and more.

  5. Documentation Day!

    Some great news about #ribbit, #rfbitbanger, #Haifuraiya, #Neptune #DSG, and more coming out from all the folks at @OpenResearchIns

    Thank you to everyone doing ambitious work!

    Wednesday's #dumbbell antenna presentation to #RATPAC went very well and kicked off another set of modeling, to be delivered this coming Tuesday.

  6. There has been a lot of #OFDM work for #neptune, and #polyphase work for #Haifuraiya over the past week. We're looking forward to another great week ahead.

    Haifuraiya, by the way, is an #opensource #heo or #geo communications payload for #hamradio.

    There is a lot of great work going on, but if you have not been hearing about it and want to, then please add yourself to our newsletter audience here: openresearch.institute/newslet

  7. Documentation Day at @OpenResearchIns today and the updates are rolling in! We'll have a really nice April Inner Circle newsletter.

    Thank you to #haifuraiya #ribbit #rfbitbanger #regulatory #RemoteLabs and all our other #opensource #hamradio teams working hard to publish great work.

    It's an honor to help make it happen a bit easier and faster.

    We welcome people wherever they are. Learn how to get started here:

  8. It was another fantastic week in #opensource #digital #radio. I call this type of work OSDR.

    There's #ribbit and #rattlegram, #Haifuraiya, #rfbitbanger, and two more projects without snazzy names that are coming together rapidly.

    That's just a part of what is going on at @OpenResearchIns

    And there is so much more out there. Tools development, #AI, free tutorials on nearly any subject, and (supply chain permitting) cheap computing and components.

    It's a great time to do this sort of work.

  9. Final stretch of an important component for a COBS protocol decoder. This goes into #Haifuraiya which is an #opensource #HEO or #GEO #amateur #satellite on the #microwave bands.

    This writeup shows how the #VHDL was designed for the #FPGA used.

    There's a bug with tlast right now, but it's a problem only when frame delimiters are stretched more than a byte. This isn't something that "should" happen, but it "could", so the decoder is designed to tolerate it.

  10. The current #JAMSAT Journal has Open Research Institute's #opensource #amateur #HEO #satellite proposal, called #Haifuraiya. Plenty of details, runs pages 17-29.
