Looking for a tiny RISC-V core that scales with your needs?

We covered FazyRV by Meinhard Kissich in our community spotlight last year: blog.yosyshq.com/p/community-...

Now it's been silicon proven on @tinytapeout.com !

My huge beautiful company is so important but also needs more money or it will collapse and die as it is weak and frail but changing the world. Please help me I am so powerful and strong and my company is so good, but also it needs more money than anything else ever has, for reasons of some sort
Yeah I need way more money than anyone ever got before. I need it because my shit is difficult right now. But it's important in ways even I haven't been able to work out. OpenAI is a serious business. Help me. Please help me please my serious company is so good. Help me

In 1994, a math professor discovered that Intel's Pentium chip sometimes gave the wrong answer when dividing. Fixing this "FDIV" bug cost Intel $475 million. I analyzed the Pentium chip and found the bug. 1/N

Oh man. They leaned in hard on the security aspects. They knew in September it was faulty. Wanted the disclosure delayed until January. No notice of a 0 day. Whose IP has been vulnerable for months? Hack my stuff please, but if you want a secure platform is any of this ok?

This is the final 200 Glasgow shipment for the original Crowd Supply pre-order batch! This finalizes the Crowd Supply campaign! It took a lot of time and effort to get here. Thank you everyone for you trust and patience!

Call for SPI flashes at #38C3

I'm developing some SPI-flash tools and want to try a variety of devices and flash chips for testing.

Got devices where it's tricky to dump in-system or rare flash chips? I'd love to test them at #38c3 if you can bring them!

I love tools for electronics. As my present for christmas I just ordered an #Buspirate6 from @buspirate.bsky.social I bought my BPv3.6 many years ago, now its time for an upgrade. I love the community and the level of discussion at the forum where I'm learning a lot of electronics.

What's your favourite part?

We love the Zero to ASIC logo and the Oscillating Bones ring oscillator!

This was one of my most popular tweets, I think mostly due to the clear macro photo I took.

Footprint was P0.5mm vs 0.65mm. So IC couldn't be soldered down. I was able to bodge existing boards in 1-2hrs.
While my friend spent 10min on the redesign (+waiting a week for mfg/ship).

Hi 👋

I'm Greg, hardware engineer. I enjoy designing and building open source hardware projects. along with taking macro photos to document the process.

Previously at a startup I used FPGAs and thermal LWIR cameras to map bushfires from aircraft

Currently doing RISC-V ASIC things at IQonIC Works
