Forget GPUs. Map the RISC-V register file to HDMI, use it as a framebuffer, and blast RISC-V across the screen on a kianV bare-metal beast. @davepl1968

You can make your own silicon with wafer.space too! Our second shuttle run is open at buy.wafer.space with a new $4 USD per die option!

First silicon just arrived. These dies are from the first wafer of my GF180MCU based Linux SoC KianV, built with a fully open source ASIC flow. This chip was part of the wafer.space GF180MCU run and hardware validation comes next. Big thanks to Leo Moser for help with the ASIC flow and to @mithro and @evezor for their guidance along the way. The picture shows the first dies. More bring up updates soon.

@Ishi_Kai_ASIC If you are super brave, you could try probing them or bonding them out. The packaged parts should be on their way soon!

去年の12月にTO(テープアウト)したWafer.Sapce GF180 Run 1 のサンプルベアダイが到着しました。 サンプルのベアダイ(生チップ)なので、現状では写真を撮るくらいしかやることはありませんので、写真を撮りました！ ishi-kai.org/waferspace/shu…

KianV Linux SoC GF180MCU @ wafer.space @mithro

🎉 New video showing off running PCI express over COTS SFP modules and associated complications along with future plans. And a small side quest with optical splitters and #ngscopeclient youtu.be/XaDa9bBucEI A bit on the long side, sorry😬 But I hope still interesting 🤞

@adafruit I have a very outdated presentation on open source FPGA generators using open source ASIC tooling and open source PDKs from 2022 when I was at Google - bit.ly/goog-fpga-22q3 See also youtube.com/watch?v=iBydHU… and youtube.com/watch?v=S0drZq… for other similar projects.

Did you miss our latest episode of Hackster Café? @mithro joined us to talk about wafer.space, which brings PCB-style pooled manufacturing to custom chips. Watch the interview to learn more! hackster.io/videos/1961

Behind the scenes of wirebonding our ASICs to PCBs

Open silicon is getting real. @mithro on wafer.space, open PDKs, and making custom chips actually accessible. Worth a listen. siliconimist.com/p/waferspace-t…

Thanks @mithro for giving me the opportunity to do a full-die KianV Linux chip run with you and get 500 chips :) wafer.space

wafer.space: Silicon now $4 USD, get inspired from Run #1! - Hackware Apr 2026 @mithro youtu.be/t6Z0_Krhshc

@elodiebear_m @splinedrive Google funded at least 80 individual projects before this run, so a whole bunch of people have done stuff already, there is a bunch of info on the Crowd Supply campaign @ crowdsupply.com/wafer-space/gf… This run's silicon should be back in Aprilish....

@splinedrive @mithro GF180MCU open ASICs? This changes the game. When can we see your test results?

I made my RISC-V ASIC/FPGA KIAN-V implementations open and free for everyone. github.com/splinedrive/ki…

@matthewvenn @Zeptobars @tinytapeout We'll have to get you to do some GF180MCU / wafer.space dies at some point!

I'm with @Zeptobars and we're going to try a FIB (focused ion beam) edit on a @tinytapeout chip. Here's the incredible machine that can do it...
