Quick writeup on how to complete and flash this year's offical DEFCON badge rhye.org/post/defcon-27…

After hearing Kerry Scharfglass @ Home and Mike Szczys @[email protected] admit to not using OCD on the hackaday podcast, I thought I'd better write about how to get started with embedded GDB. It's a lot better than printf! rhye.org/post/stm32-wit…

In an effort to better understand #FPGA development myself, I've written a brief overview of Verilog and simulation with Verilator. Hopefully others may find it useful. rhye.org/post/fpgas-for…

Stuck at home? Maybe now is the time to read up on how to assemble and program your own simple open-source #FPGA dev board with the #yosys + #nextpnr toolchain. rhye.org/post/fpgas-1-r…

A walkthrough of how to make your own #FPGA based animated GIF panel, using the open source #yosys + #nextpnr toolchain rhye.org/post/fpgas-2-l…

New tool: Yostat. A visual way to examine the resource usage of #yosys designs. Tested with both #ecp5 and #ice40 #FPGAs, but should work with anything Yosys supports! github.com/rschlaikjer/yo…

Rocking out to the #DEFCONSafeMode tape but don't have an oscilloscope? Got you covered. #DEFCON #DC28 youtube.com/watch?v=RWaPUv… github.com/rschlaikjer/li…

How to build a custom #RISCV based SoC from scratch using the VexRiscv CPU and the #yosys+#nextpnr toolchain, from gateware to firmware: rhye.org/post/fpgas-3-s…

Thanks to the DEF CON HHV for a fun CTF! Initial writeup of my solves with some code samples up at rhye.org/post/defcon-29…

Built a cute little SFF PC using the Cubeor Aski 2 with some custom additions. Pictures and detailed thoughts on the case: rhye.org/post/cubeor-as…
