HP-35 in FPGA

[Ren]

Hackaday's upcoming Remoticon has a speaker, Rob Weinstein, who will describe how he duplicated the functions of the HP-35 in FPGA using the original patent?
(I hope I got that right)

I didn't see his name when I searched this website; is he here? (Is he banished? shudder!)

Ohhh, very interesting. I'm looking forward to his talk. There is another very interesting talk about the SkyWater kit...

Hi,

That was my presentation at Remoticon 2021. I hope you liked it. I had some technical issues with the presentation, namely Zoom wouldn't see my webcam and in the resulting panic, I shared my presenters view instead of the slideshow view. Other than that, it seemed to go okay.

Here's a link to a short video about the final calculator: https://vimeo.com/648116637

I'm told that the Hackaday folks will be publishing the individual presentations on Youtube, a couple each week. I'll post a link when it's available.

I'm happy to answer questions, let me know.

Thanks,

-Rob

Wow! that was a super great presentation.
With the level of research that you did and the details you put into this project, I am amazed that it only took you 750 hours to complete it.
Thank you very much for doing it and for sharing it.

Thanks for the nice comments!

Regarding the time I spent, 750 hours was just the research and initial Verilog design and simulation. I spent another ~750 hours on designing and building the working replica.

I am really impressed! It's incredible the amount of work/research you have done.
Congrats!

Hi,

I promised I'd post a link to the Hackaday article when it became available:

Remoticon 2021 // Rob Weinstein Builds an HP-35 from the Patent Up by Chris Lott

Thanks,

Thanks Rob W.
I have given up Hackaday for Lent, so I probably would have missed the article!
