This is my personal electronics website showcasing DIY projects, measurements, modifications, reviews, investigations, etc. Currently the focus is mainly on audio electronics. At least for now this is just a hobby although I have started selling some boards to fund future development and get at least some of the money back spent on these projects. I sell assembled boards on Tindie for now, and bare PCBs and occasional one-off boards here on my website.

At the moment most boards are audio. My design philosophy is very engineer-like, solid technical foundations and measurements first. I’m lucky to have access to state of the art Audio Precision measurement kit at my 9-to-5 work; therefore, I am able to provide comprehensive measurement results of my boards.

At the moment I have:

• DACs, performance up to -115 dB THD+N and 121 dBA dynamic range
• ADCs, performance up to -113 dB THD+N and 124 dBA dynamic range
• Various addon and supporting boards for DACs and ADCs such as balanced outputs, I2S to S/PDIF converter, power supply baseboards and so on

I have lots of ideas and am constantly developing new boards. However, progress is quite slow as this is just a hobby. So please bear with me.

Other relatively recent projects that are not part of Wee DAC.

Measurements of specific components or devices.

Generic information sharing of theory, measurements, teardowns etc.

Practical tips that has come to mind that may not be so obvious and are worth sharing.

These are older projects I am not working on anymore. Some of them are in active daily use, some completely ditched and forgotten. I do have ideas to improve and release new versions of some of them though. One day, maybe.
