Last year and this spring I spent a lot of free-time on DIY electronics and as my full-time job is also electronics related, I needed to take a few-month break. I just didn’t feel interested, inspired, or motivated anymore. During the time off I focused a bit more on my photography hobby. I hoped that after a break I would feel motivated to do more electronics again. While even I had my doubts, the inspiration is back! I am designing new boards again. There will be a new DAC plus addon boards; the design and ideas are based on the H-DAC. I will also try to make assembled boards available to buy at some point.
