iCEBerg-FPGA
The iCEBerg FPGA development board is my first take on an FPGA design using the Lattice iCE40UP5k. The design was created in KiCad and is fully open source.
Pinecil
The Pinecil is a portable open-source soldering iron, in it's heart a RISC-V core.
Bachelorthesis — Waveform Generator as ASIC
During the work on my bachelor thesis I developed my first digital design, the waveform generator, and implemented it as ASIC with the open source 130nm SkyWater PDK.
Steam Deck
Finally my Steam Deck is here!
The ULX3S — ECP5 based FPGA Board
In this post I introduce the ULX3S, my latest addition in FPGA boards. Here I show how we can use the Open Source toolchain to program a simple blinky example.
Our group project: The Mic-1
As a project at the FH Joanneum, we as a team developed a Verilog implementation of the Mic-1.
A look at the PS ∕ 2 protocol
Before I can develop the gateware to read keystrokes from my PS/2 keyboard, I first need to know how the protocol works.
Assembling the levelshifter PCB
In this post I show the process of assembling the levelshifter PCBs with my DIY hotplate
Reflow Soldering Iron
This is the story of how an old iron gets transformed into something beautiful.
